There are a variety of possible technical solutions to resolve the US law enforcement's fears about criminals and terrorists "going dark" in regards to their access to mobile devices. The question isn't what is technically possible or even what is legally feasible, it is whether we want to live in a country where these solutions are enshrined in law.</div>
<div dir="ltr" style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 12.8px;">
<br /></div>
<div dir="ltr" style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 12.8px;">
As US citizens, we have long accepted that, with a warrant signed by a judge shown sufficient evidence, law enforcement could search our homes or any other space and anything within them. If there is a safe in your home, Law enforcement has the right to break into it with a warrant. US law enforcement is currently trying to extend this line of reasoning to our mobile devices as though it were the same sort of inquiry. Missing from this reasoning is the fact that <u>mobile devices contain far more info about us than our homes</u>. How often do we do Spring cleaning on our mobile devices? If we run out of space on our phones, we can get more space or shuttle data to on-line services accessible from our devices. If we run out of space in our homes, it is a much harder problem to solve and we are under constant pressure to dispose of traces of our lives. Mobile devices bring all of our data together in one place and commonly access all our history, too. Phone manufacturers and mobile service providers often provide tools or services to move all of your data from your old device to your new one. It makes sense: It encourages customers to buy more. These capabilities keep an unprecedented amount of history accessible to if not stored directly on our mobile devices.</div>

If I want to know what I was doing in 2007, I search my Gmail. If I want to know what I was doing in 2001, I search my previous webmail provider. Law enforcement may be able to get separate warrants to search both of those service providers. Getting a single warrant for my mobile device, by contrast, gives them the passport to <u>all</u> of my data, no matter which medium or service it is stored in. At some point, many years ago, I ran out of physical space and time to keep and manage even a small portion of these data in my home. </div>
<div dir="ltr" style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 12.8px;">
<br /></div>
<div dir="ltr" style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 12.8px;">
Arguably, my home PC would give a searcher access to these same data sources. The difference is that my home PC doesn't go places with me, logging everything as I go. My mobile device is my GPS, storing all the places I lookup driving directions to or map-based searches for and which route I took, when, whether I deviated. I'll often search for businesses using a mobile map app to constrain the results to those nearby or more quickly get to a place's phone number, menu, etc. Those data are accessible to the map service provider but are also accessible on or through my mobile device with everything else. My mobile device is also my primary camera. By default, it time-stamps and geolocates every photo I take with it. Certain apps scan these photos for faces, conveniently making who I was with, when, and where accessible from a simple app. Again, these photos may be backed up or shared via on-line service(s), but the <u>all</u> of originals with full resolution and details are on the phone and it would be more policework to get warrants for all of the services I could possibly use to share and backup photos. There are also logs that the device manufacturer or service provider keep on the device that indicate which tower I was near at what times, filling in gaps between map searches and photos with a continuous log of where I was potentially going back several years. Which apps I use, when, and what for are logged, too, not only web search history and cookies. Mobile devices tend to store more passwords to my on-line services, too. Typing a complex password on a PC is far easier than on a tiny touchscreen so its more likely that I'll check that "remember me" box and less likely that services will even ask. I use a variety of apps services to make voice calls, message,<span style="font-size: 12.8px;"> take notes, manage my calendar, and reminder myself of things. Regardless of whether these data are stored in on-line services, they are of little value unless they are with me when I need them. Therefore, the best place to access them from is my mobile device. </span><span style="font-size: 12.8px;">The single place that</span><span style="font-size: 12.8px;"> </span><u style="font-size: 12.8px;">all</u><span style="font-size: 12.8px;"> of those logs, calls, messages, notes, meetings, and reminders can be accessed from is my mobile device. </span></div>

<div dir="ltr" style="background-color: white; color: #222222; font-family: arial, sans-serif; font-size: 12.8px;">
<span style="font-size: 12.8px;">No other location, device, service, or data source has as much information about me, my identity, my thoughts, my beliefs, my history of actions, meetings, locations, and communications than my mobile device. It stores things I have long since forgotten, <u>making access to it more personal than direct access to my own memory</u>. Giving someone access to this device gives them unrestricted access to </span><u style="font-size: 12.8px;">all</u><span style="font-size: 12.8px;"> of it, unfiltered, unbiased by my feelings of what is important and what I can forget. Forgetting is easy. Deleting is hard. Therefore, access to my mobile device is far more invasive than access to my home and should be subject to far greater protections from access, even by those with the noblest of intentions.</span></div>

I created a chart of project financial data similar to one we use in Excel with some dummy data. Google Sites is built into Google Apps for Business and would supposedly allow easy publishing of these data. When I selected "Publish" on the chart, it gave me some HTML to put on any site as a way of publishing the chart. Here goes:<div><br /></div><div><br /></div><br /><br /><script type="text/javascript" src="//ajax.googleapis.com/ajax/static/modules/gviz/1.0/chart.js"> {"dataSourceUrl":"//docs.google.com/spreadsheet/tq?key=0AoL33dLEFM8edDFuTUZBNTlxTW1ITE1vZWlORERRdXc&transpose=0&headers=1&range=A1%3AG12&gid=0&pub=1","options":{"vAxes":[{"title":"Period Cost ($k)","minValue":null,"viewWindowMode":"pretty","viewWindow":{"min":null,"max":null},"maxValue":null},{"title":"Cumulative Cost ($k)","viewWindowMode":"pretty","viewWindow":{}}],"series":[{"color":"#8e7cc3","type":"bars"},{"color":"#3d85c6","targetAxisIndex":1},{"color":"#ffe599","type":"bars"},{"color":"#ff9900","targetAxisIndex":1},{"color":"#741b47","type":"bars"},{"color":"#ff00ff","targetAxisIndex":1}],"title":"Test Financial Chart","booleanRole":"certainty","animation":{"duration":500},"legend":"bottom","vAxis":{"format":""},"focusTarget":"category","useFirstColumnAsDomain":true,"type":"line","hAxis":{"title":"Month","maxAlternations":1,"format":""},"isStacked":false,"width":1000,"height":600},"state":{},"view":["{\"columns\":[{\"calc\":\"stringify\",\"sourceColumn\":0,\"type\":\"string\"},1,2,3,4,5,6]}","{\"columns\":[0,1,2,3,4,5,6]}","{\"columns\":[0,1,2,3,4,5,6]}"],"chartType":"ComboChart","chartName":"Test Financial Chart"} </script><br /><br />As you can see above, it works quite well. It works even more easily in Google Sites, where you can navigate through the user interface to the specific Google Doc, Chart, or whatever you want to show without inserting any code. The only caveat is that you have to change the permissions on that doc to make it accessible. Otherwise, it is only visible when someone you explicitly share the document with has signed into their account.2012/02/testola.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-9190762267229871652Thu, 25 Aug 2011 22:31:00 +00002011-08-25T18:36:37.518-04:00BBM Music - If you can't compete, lock your customers in<div><a href=" Music beta announced</a></div><div>BBMessenger is one of the few features remaining locking non-business BB users into the platform. They've successfully added a new feature in BB Messenger Music (BBMM?) that works in concert with it to bring users who might use a Bleakberry but not BBM into the fold. Now they'll be getting pressure from any friends who use BBMM to hop on it and share their music so that those friends can have 25 more songs for free and it might seem reasonable because they'll get free access to 25 songs per friend, in turn. Social pressure can be a powerful thing. If your friend leaves who has a song you like but haven't purchased, yet, you must buy that song or find another friend to regain access to it(?). So, when you're in a phone-buying situation, you'll have that additional consideration holding you back from switching platforms (on top of the unfamiliarity of the other platform, potentially outrageous ETFs or unsubsidized purchase prices, contacts transfer, and all the other things going through your mind). Uncertainty motivates people to maintain the status quo. </div><div>
<br /></div><div>I remember watching a poor Circuit City salesperson one day deal with a lady and her bratty daughter who kept whining about whether the new computer Mom was buying her would have AIM. She didn't care what else it did, how much it cost, and didn't bother to look into the fact that she didn't even have to be a paying AOL member to have access to it from *any* computer. The salesperson could have pointed at the most outrageously-expensive model in the store and said, "I know for a fact that one will run AIM," and Mom probably would have bought it just to get her daughter to shut it. Silly perceived lock-in situations like that keep companies (AOL, Circuit City) in business long after they've stopped competing when they occur as part of the buying decision. </div><div>
<br /></div><div>On the plus side, BBMM has the potential to improve music discovery, which IMHO stinks with existing on-line music stores, assuming wide adoption (Could it possibly be worse than Ping?). More pragmatically, however, if RIM can have one more silly thing locking people into their platform, they want it because they're hemmorhaging market share. Whether its actually good for consumers - as partnering with an open platform like gchat might be - is secondary to their business interest as they try to remain afloat in a sea of innovative competitors.</div>2011/08/bbm-music-if-you-cant-compete-lock-your.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-6696722810424648457Sat, 14 May 2011 14:15:00 +00002011-05-14T10:52:14.613-04:00Chromebook Please<span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; ">I would love one of these <a href=";. I do a fair amount of computer support by day and the potential to make life so much easier is obvious to me with Chromebooks. I bought a netbook a couple years ago looking to do just what a Chromebook does - quickly get on the web, look at some photos from our cameras on vacation, and entertain myself on the airplane. Instead, I got MS Windows which takes away any notion of doing anything quickly and adds a support load, a tiny screen which Windows clearly wasn't designed for, and 2 hour battery life. I wish the screen were just a bit bigger, the battery life alot better, and the web a bit faster. </span><div><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; "><br /></span></div><div><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; ">Chromebooks hold a similar appeal to me that iPads do for many: Simplified, portable computing.

There's no waiting for Windows Update only to launch my browser to find that there's a browser update only to finish installing that to find that there's an update to Flash that needs installing. There's not startup programs slowing my down. There's no worries about backup, whether it really went to sleep when I closed the lid, viruses, or other malware (do I trust this download?). You just open the lid, login, and you're on-line. With all that, they're still cheaper than iPads.</span></div><div><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 14px; "><br /></span></div><div><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 14px; ">I'm not sure how big a deal the 3G connection is. I really like that they've bundled the connection in and removed the need for a contract. I'm doubting I'll like the pay-as-you-go rates, though, whenever they're announced. The fact that I'm already paying $30/month for an unlimited data connection from my phone and I can't use it for the Chromebook without paying even more would grate on me no matter what. I really like that they've included dual-band WiFi, though, so I can use it with my 5GHz home network.</span></div><div><div><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; "><br /></span></div><div><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; ">What I'd love to see next is simpler ways to install the servers and webapp hosts at home so I could have my own private cloud.

I've personally been affected by user data theft at <a href="; and Sony's <a href=" Network</a>. Epsilon's breach revealing names and e-mail addresses was low impact but Sony's loss of control of everything you give them is no small matter: Name, Address, Credit Card Number, CC Expiration Date, Date of Birth, e-mail, <span>username</span>, and <span>password</span>. Storing your Credit Card Number was optional but the rest was mandatory to access PS3 features such as on-line play, downloadable content, and third party services such as Netflix's streaming movies. That's most of what someone needs to steal your identity. Furthermore, if you thought of this account as a throw-away, you may have used a username and password that you use elsewhere, potentially allowing hackers access to gain additional info and sell it to the highest bidder. Given that you have to enter your username and password with a D-pad and on-screen keyboard, a pretty frustrating system, users were certainly incentivized to use an easy-to-type password.<div><br /></div><div>We trust companies who store our personal information in an on-line system more than they deserve. According to Sony's <a href=" on their breach</a>, credit card numbers were stored encrypted and they're only warning customers to assume their CC numbers were released in an "abundance of caution." That statement in addition to their statement that they're rebuilding the network from scratch with security upgrades says to me they aren't very confident in the encryption, key management, or communications security they used to move that info around. It is apparent that no one scrutinized their system before it was approved to store all this info and expose it to the open internet.</div><div><br /></div><div>It shouldn't be possible for this to happen for all 77 million of their customers in a single breach. The concept that a firewall keeps the bad guys out has been disproved again and again. Critical information needs to be protected making the assumption that the bad guys are inside your network. Simple, mature techniques for protecting this kind of information (https, AES encryption, etc) have been in place, implemented on many platforms, and promoted by security experts for many years. Often, turning them on requires no more than ticking a checkbox. All the security experts get to say, yet again, "I told you so."</div>2011/04/on-line-security-they-told-you-so.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-7791307393242684491Fri, 17 Dec 2010 04:00:00 +00002010-12-16T23:12:24.130-05:00chromechromeosdatagooglemobileprivacyHigh Hopes for ChromeOSGoogle held an event last week that provided more detail on their efforts surrounding ChromeOS and announced a pilot program. There seems to be much confusion around two questions:<br />1) What is it?<br />2) Why should I care?<br /><br />I can address #1 somewhat. ChromeOS is an operating system Google is making available to partner computer manufacturing companies that boots straight into the Chrome Web Browser and really restricts itself to using the web. The concept is that people using netbooks and even full-power laptops and desktops often spend the majority of their time in the web browser. Google has improved the Chrome Web browser, incentivized web app developers by adding a web app store, simplified the operating system to running this single application, baked in the latest security capabilities in a user-friendly fashion, and dictated inclusion of up-to-date wifi and 3G radios in the hardware so that users can be almost always connected. <br /><br />So, why should you care? Google partially answers that question here: <br /> />For myself, manufacturers should be able to turn this platform into cheap, simple to use, long battery-lived, quick access computers that do nearly all the things people do on today's computers and more. Powerful applications can run on powerful servers instead of requiring you to lug around beefier hardware. Simple applications stay simple, are always up to date, and don't expose your data to loss or theft when, inevitably, the computer is damaged or lost. The frustrating days of paying thousands of dollars for a laptop, then hundreds or thousands more for applications, loading it up with private info, personally owned media, and precious memories, only to leave it in the airport security line and lose everything may soon be behind us.<br /><br />Google's CR-48 pilot program demonstrates all these benefits for some, however, access to them remains in the future for the larger marketplace. Google's pilot program demonstrates what can be done but its up to other parties to carry this forward. Manufacturers need to come out with compelling hardware at a reasonable price, soon. Developers need to leverage the power of HTML5 in their web apps to make them perform like locally-installed apps. More web development of private cloud technology is necessary so that people and businesses have a secure place to keep their info that doesn't belong to a third party. Finally, wireless carriers need to get on-board. Nobody wants yet another 2 year, $60/month contract tied to a single, limited device. I really don't want to pay by the byte, either, (would you want to pay for your electricity by the electron?) but that appears to be the way things are headed. The 100MB/month free setup Verizon includes with Google's CR-48 pilot program is encouraging but it remains to be seen what will be offered with real products. Here's hoping it all comes together2010/12/high-hopes-for-chromeos.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-5592466778973172123Thu, 02 Dec 2010 04:05:00 +00002010-12-02T00:17:25.473-05:00frequencytime capsulewifiWhy Is My Home WiFi Flaky?<div style="text-align: left;">I spent probably way too much on an Apple Time Capsule a couple years ago. In an attempt to get my money's worth, I have been trying to get alot of use out of it. Its supposed to do alot: dual band (2.4 and 5 GHz) WiFi, Gigabit Ethernet, 1 TB network-shared hard drive built-in, and a host of other Appley features. Since nearly every WiFi device is compatible with 2.4 GHz, I've left it in that mode for those couple years. The coverage is flaky, however. Videos studder, even when I'm playing them from a share from another computer in the house, and sometimes connections just drop. In an attempt to find out why, I read up on and downloaded a free program called <a href="; which produces a handy graph of all the WiFi networks in range and what channel they're on. Here's what I found:</div><div style="text-align: center;">2.4 GHz Networks</div><div style="text-align: center;"><img src="; border="0" alt="2.4 GHz Networks" /></div><div><span class="Apple-style-span" style="color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; "><br /></span></div><div style="text-align: center;">5 GHz Networks</div><div style="text-align: center;"><img src="; border="0" alt="5 GHz Networks" /></div><div><span class="Apple-style-span" style="-webkit-text-decorations-in-effect: underline; ">(Network names are obfuscated to protect the innocent) There are multiple, overlapping networks in range at every available channel in the 2.4 GHz spectrum. While the WiFi specs have algorithms in place to continue operating in spite of all the interference, they're pushed to the limit by all the overlapping networks. By contrast, there are far more channels in the 5 GHz spectrum and only a single network in range. A 5 GHz network in my house could easily operate without any interference from neighborhood WiFi networks.</span></div><div><span class="Apple-style-span" style="-webkit-text-decorations-in-effect: underline; "><br /></span></div><div><span class="Apple-style-span" style="-webkit-text-decorations-in-effect: underline; ">Luckily, or so I thought, the Time Capsule supports 5 GHz WiFi, as well. As I found when I switched it over to 5 GHz mode, however, the performance was dismal. Despite having no other networks interfering with it, speeds and reliability in 5 GHz mode were even lower in some cases than in the overcrowded 2.4 GHz mode. It was actually worse when my laptop was in the same room as the Time Capsule, so range isn't the cause. After using jperf to take some actual throughput measurements at a few places in the house and comparing them to what competing wireless routers can do (2-7x faster in on-line reviews), I've decided to retire the Apple Time Capsule. Since I've got the Windows Home Server handling backup of both PCs and Macs in the house, now, even its use as a Time Machine backup target is no longer relevant. What a colossal waste of money.</span></div>2010/12/why-is-my-home-wifi-flaky.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-57529919474131075Thu, 02 Dec 2010 03:30:00 +00002010-12-02T00:21:00.346-05:00internet tvlicensingvideoDon't Get Me an Internet TV Device for Christmas<div style="text-align: left;">A startling and confusing array of Internet TV devices have been launched over the recent months, all competing to be your gadget of choice for getting internet content onto your TV. Even more confusing to most folks is why they would want such a device since none of them gives us access to the full web we see on our computers. I was in the middle of drafting another diatribe on the topic when I came across this series of posts from Tim Higgins over at Smallnetbuilder.com: <a href=" style="text-align: left;"><br /></div><div>That link is to his most recent post where he comes to the same conclusion I have: Its all a big waste unless deals are cut with the content companies. He comes to another conclusion that the best device for watching internet content on your TV is still the computer. Apparently, content license owners are coming to the same conclusion and exerting more control over what they make available online. Just tonight, my wife and I sat down to watch back episodes of a show a good friend turned us onto - The Big Bang Theory - and we've become hooked on. Its not on Hulu, Netflix, CBS (who broadcasts it), and though it shows up in Amazon's VOD service, you get this annoying message: </div><div><div><a href=" currently unavailable</a></div><div><a href=" to our licensing agreements this video is currently not available for purchase or rental.</a></div></div><div style="text-align: center;"><span class="Apple-style-span" style="color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; "><img src="; border="0" alt="Amazon licensing error message" /></span></div><div><span class="Apple-style-span" style="color: rgb(0, 0, 238); -webkit-text-decorations-in-effect: underline; "><br /></span></div><div>It's a not so subtle reminder of who, exactly, is in charge of what we watch, when. Like it or not, our options are to wait for the license owners to come around or work around them and be labelled a "pirate." As nifty as the Internet TV devices are, technologically, I don't want to be in tonight's situation of searching all over, site by site, only to be thwarted by someone else's "licensing agreements." And, as Tim Higgins points out, even the best of the available devices still have their bugs to be worked out. </div>2010/11/dont-get-me-internet-tv-device-for.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-3957151273862450044Fri, 24 Sep 2010 02:53:00 +00002010-09-23T23:12:11.352-04:00Windows Home Server and Apple Time CapsuleI just got a HP Mediasmart Windows Home Server and was digging through some forums about another issue. I came across these very <a href=", detailed, instructions</a> on homeserverhacks.com for how to get the remote access features working with my Apple brand router.<br /><br />I'm in the middle of backing up all my systems (two Windows laptops, an older desktop, and a Mac Mini) to the server at the moment so I haven't messed with it. So far, the system has performed well. A few warnings, though:<br />1) The Media Collector that comes with the HP-branded models works great for automatically collecting and organizing music from iTunes. Some sites claim it does the same thing for videos from iTunes and photos from iPhoto. That hasn't been the case in my first 24 hours of experience. iPhoto's approach of storing everything together along with a DB only it can manage doesn't lend itself to sync with any other system and HP's software is no exception. Since we switched to using Picasa a while ago, which uses the approach of leaving image files where they are and detecting new ones as they arrive, our more recent photos have synced over but the old ones from iPhoto have not. I'm not sure what to think about the iTunes movies. Its amazing what the Mediasmart Server does, but it doesn't quite meet the expectations I had, so far.<br />2) The point of the Media Collector is gathering all your media together from different systems. You get out of this process, however, what you put into it in terms of organizing your media before the collector goes to work. Again, in contrast to its nice handling of music, photos and movies are collected into the server shares by username. Unless you happen to use the same account on all your systems with similar folder structures and everything it its default location (e.g. all your pictures you want collected in the windows "My Pictures" folder), Collector makes an equivalent mess out of your files in its shares. One option I found out about too late is enabling the Guest account on the server. This option should allow everything to be Collected under that single username.2010/09/windows-home-server-and-apple-time.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-6860650016995887339Fri, 06 Aug 2010 19:44:00 +00002010-08-06T16:10:57.340-04:00WSJ and re-reporters miss point on IE In-private Filter<span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; ">The Wall Street Journal recently published an article titled "<a href=" Quashed Effort to Boost Online Privacy</a>" on Microsoft's internal struggles about how to implement their "In Private Filter."

Steve's presentation makes it clear both implicitly (with his body language and dramatic pauses) and explicitly (with what he says) that he thinks there's no real problem here. He expresses his view that the only reason all this hubbub occurred is because the media is blowing the problem out of proportion. <div><br /></div><div>Apple's successful manipulation of the media has led to some of the best free advertising for any tech company in existence. Now, the combination of media uncertainty about how to properly explain a legitimate technical performance issue with the iPhone 4 and a lack of clear technical explanation from Apple has led to negative coverage. Boohoo. Welcome to real world. The media giveth and the media taketh away. They especially take away when customers report a real problem and the company responsible tries to claim everything but responsibility for it. </div><div><br /></div><div>You can't have it both ways Apple. This performance issue can't be both the result of an Apple design choice to expose the antenna and its "weak spot" on the outside of the phone and not your fault. The extremely limited data Apple provides in its presentation show an increase in dropped calls from the iPhone 3GS to the iPhone 4. Given that the "revolutionary" antenna design was supposed to improve wireless performance, seeing poorer performance is clearly an issue. Again, you can't credibly present those data showing an increase in dropped calls and then claim there is no technical issue.</div><div><br /></div><div>As someone who knows just enough to be dangerous about radio signals and electronics and is willing to speculate based on the coverage I've seen so far, I think the first failure is that no one - not Apple, popular media, the tech media, or any experts brought in to comment - has succinctly explained the problem and its likely causes. Anandtech did a great job of proving quantitatively, as best as you can with something as complex as RF devices and without the complex test equipment, that there is a problem in their article: <a href=" 4 Thoroughly Reviewed</a>. Where they didn't do so well is in explaining it <i>plainly</i> and this poor explanation was repeated in follow-up interviews such as CNet's <a href=" Roundtable</a> and <a href="; (This Week in Tech) episodes. I can give the journalists, podcasters, and bloggers some leeway because they're not all experienced engineers and this poor performance - and its inconsistency among users - is likely due to a complex combination of technical issues. </div><div><br /></div><div>As I've said before, its easy to criticize and harder to do better. Here's my attempt at doing better. </div><div>Caveats: Modern radios and the antennas that work with them are extremely complex. I understand antenna design is hard and explaining it is even harder. Its not possible to explain plainly something so complex without making some gross generalizations.</div><div><br /></div><div>Background: Every cell phone manufacturer takes as many of the complex factors determining connection performance as they can into account in their phone design. Its a fact of life in the mobile wireless industry that you will have something nasty like a hand (in terms of causing RF signal attenuation) covering your antenna and blocking its ideal signal path to the tower. I'll call this Problem A. Manufacturers have handled this problem by making ever more sensitive receivers, better amplifiers, and moving antennas around inside their phones. Since modern handsets are about the size of a hand, the insides of the case provide limited options for improving performance by moving the antenna. The wireless standards bodies have addressed these realities by including all sorts of digital encoding and processing schemes into the communications spec such that weaker and weaker signals still result in a successful connection. </div><div><br /></div><div>The simple part: Apple thought they could break the mold and do something revolutionary by putting their antennas around the outside of their phone, thereby reducing the effect of Problem A. Instead, they added a second problem, Problem B, that occurs only when the phone is held a certain way. When a user physically touches the two antennas running around the outside and electrically connects them, they drastically change the RF properties of the antenna-hand system and make the antenna less sensitive to the frequencies it uses to connect. Problem B reduces signal at the receiver which compounds with Problem A to make the signal drop even more sharply. Problem B simply cannot occur when the antenna is insulated inside the handset's case. </div><div><br /></div><div>To put some numbers on these problems, Anandtech measured their compounded drop (A&B) to be 24 dB, or about 250x less signal than is otherwise received. They further measured the attenuation with the phone in a case, essentially isolating Problem A, to be 7.2 db, or about 5x less signal than is otherwise received. So, Problem B knocks the signal down roughly (250/5=) 50 times! Whereas internal antenna designs have to deal with Problem A, Apple's iPhone 4 antenna design has to fight the compounded result of both Problems A and B.</div><div><br /></div><div>The complex part: So, why don't all customers see the same increased call-drop or poor connection quality behavior? Three reasons:</div><div>1) Not all users expreience problem B. They either don't hold the phone that way or they have a case which prevents it. They only experience Problem A. Therefore, they don't experience the extra ~50x drop in signal strength.</div><div><br /></div><div>2) Digital encoding technology hides the issue in strong signal areas. As previously mentioned, and explained in Anandtech's article, a modern digital handset can maintain its connection at the same level of quality in the presence of an extremely low signal that is still above threshold as in the presence of a high signal. A signal weakened 250 times can still be above threshold. With digital technology, as long as your signal is "good enough," the connection stays good and the user notices no ill effects. When the signal level drops ever so slightly below the systems' threshold, however, the connection just drops. There's very little in-between where the connection sounds fuzzy or distorted like with older analog technologies. This technology effectively hides from users whether they're in good or bad signal areas for all situations above threshold.</div><div><br /></div><div>3) Wireless phone users have become accustomed to calls dropping and intermittent connections. There are enough other problems wireless handset manufacturers and carriers face, not described here, to take up the rest of the alphabet and then some. AT&T has gotten its coverage and service heavily criticized of late, and I think there is some merit in that criticism. Regardless of AT&T's specific issues, all carriers face these problems, all drop calls, all drop connections. If you hear that AT&T's service is poor in your area and buy an iPhone anyway, then dropped calls and intermittent data connections are something you're expecting. What are a few more of something that has not previously been quantified?</div>2010/07/apple-apologizes-reluctantly-for-iphone.htmlnoreply@blogger.com (AG Crazylegs)0tag:blogger.com,1999:blog-7131598542764201761.post-1343695011174344359Thu, 10 Jun 2010 20:28:00 +00002010-06-10T18:35:12.490-04:00User-focussed mobile data plan modelIf you look at some of my older posts, you'll see that I'm no fan of the data plan model currently in-place in the mobile wireless industry. Flat fees for "unlimited" plans that are, in fact, quite limited, with zero accountability for the quality of service provided, and inordinately large and increasing termination fees that hamper consumer mobility just aren't good enough. The recent changes announced by AT&T and rumored to be coming soon on Verizon where users are charged for "buckets" of bytes doesn't make sense to me, either. These plans create a false sense of scarcity for something that, once "enough" infrastructure is in place, costs the carrier nothing: the byte. In fact, the majority of costs to a wireless carrier are incurred to install and maintain a given capacity and those costs remain nearly static no matter how much you use them. The cost per byte actually drops the more customers consume them. This by-the-byte approach rolls out at the same time as mobile ad platforms (which use data, too) are rolling out. How much are you willing to pay to <span style="font-style:italic;">see</span> ads? Since no system is in place to inform users of how much data they currently use, until they exceed their arbitrary limit and find out in their increased bill, metered usage doesn't make sense, yet, and still fails to incentivize carriers to provide higher capacity and availability. This approach continues to put all the information, and therefore power, in the hands of the carrier while all the responsibility for managing usage falls to the customer. There are many criticisms that could and should be applied to the wireless industry (not the least of which is the spinning of the word "bandwidth," but that's a whole other rant). <br /><br />It is easy to criticize, however, and hard to propose a more reasonable alternative. The fact is that carriers are saying they will provide feedback to users about how much data they have "used" along with warnings when they're about to exceed the plan amount. Also, bytes, like minutes for phone plans (as in, used for talking), are fairly easy for users to understand and carriers to monitor. The more data you send and receive, the more you pay. Carriers, for their part, need to track usage as part of normal operations to ensure their network is balanced, anyway, so why not report those data to users. Its simple, in concept. How else should usage be tracked if not by byte?<br /><br />So, what if we came up with a way to meter the bill based on something that's focussed on user experience? The primary complaints customers have, and the primary challenges of a carrier, are capacity and availability. If there are great connections all over a city but poor connections outside the city, what happens when you're driving or taking the train home for the evening? Your call gets dropped and your files start downloading slowly. So, why should you pay the same price while you're in a bad area as you do in a good area? Reversing the scenario, what load (and therefore cost to the carrier) do you put on the network when you're in an office building where the signal doesn't penetrate? How about when your phone is powered off? None. The carrier allocates zero wireless capacity resources to you when you're off the grid. So, why should you be paying at all for the significant portion of the day when you're not able to use the service? I suggest billing based on two factors: 1) The Carrier's quality of service to the user (i.e. speed and latency) and 2) The portion of time that service is available to the user (availability). The better job the Carrier does, the greater proportion of the plan fee they can charge their customer at the end of the month. <br /><br />As with any idea, the implementation details determine everything. I'm not advocating making the wireless business so volatile that carriers can hardly stay in business. Reasonable limits should be in place such that customers have a minimum fee to pay, even if they choose to turn their phone off all month. There are some costs to having the network available to you, even if you don't choose to use it. Likewise, reasonable limits should be in place on how much the carrier can charge if they achieve 99.99% coverage, quality, and reliability. That maximum amount should be known and agreed to when the plan is purchased. Carriers should publish their quality and reliability numbers, by area, every month with history reported for at least the length of the longest contract offered, so that customers can make informed choices when selecting their carrier. <div><br /></div><div>This approach increases complexity, though, by using several numbers to determine your bill. There are many ways to simplify that complexity, however. Speed and latency thresholds could be set in the plan such that the sole variable determining the bill is time of availability better than both of those thresholds. By contrast to AT&T's recent announcement of $15 for 2GB with $10/GB after that, perhaps you'd pay $15 as a minimum for the month plus $15 x the percentage of the month your phone had a connection at the agreed quality available to it (as determined by periodic connection tests from phone to internet firewall). I'm sure many methods of implementation would be thought up and tested in the crucible of the market. The point is that customers would pay more for a better, more consistent experience and less for a worse experience. Right now, you get what you get and you pay the same or even more, regardless.<br /><br />This approach has merits for the customer in that it re-balances power such that more is in hands of customers and it gives carriers an immediate and continuing incentive to improve the customer experience. It also gets the industry away from billing customers for a commodity that has no direct link to cost - bytes - and which customers have little to no control over (web pages don't tell you how big they are before you load them!). Instead, the industry moves towards billing for the primary cost drivers - capacity and availability. Carriers who provide a better experience by expanding and balancing their networks better make more money. Customers pay for availability at an agreed quality level.<br /></div><div><br /></div><div>So what's wrong with this idea? First of all, carriers would never willingly agree to giving up so much power. Gov't regulation would be required and that's tough to get right. Secondly, its complex. The only way to ensure lawmakers, who don't really understand the issues, get those laws right is to make things crystal clear, black and white, such that its clear they're doing the right thing and gathering the approval of constituents (who often don't really understand the issues, either) by voting for it. The industry has already convinced us that paying over $1500/MB for text messaging (that's about what 20 cents per message works out to) mak
