Beck's paper, "Enhanced TKIP Michael Attacks" [a href="http://download.aircrack-ng.org/wiki-files/doc/enhanced_tkip_michael.pdf"strongPDF download/strong/a], describes how to work around certain assumptions in the MIC (Michael) checksum that's used to ensure a packet hasn't been tampered with to insert truly massive hunks of data without breaking a TKIP key. /p pFor certain kinds of routine network traffic, enough data is already known in the right circumstances to brute force one missing piece and insert from 120 to 568 bytes, if I read the paper right. The Michael checksum isn't changed, but the packet is inserted as a fragment before a correctly checked hunk of data, so the receiver has no suspicion of tampering./p pWorse, this technique can be used in some cases to decrypt data headed to the client, even though the TKIP key hasn't been recovered./p pAs with the previous attack, a lot of stars have to be in alignment. The biggest requirement is that TKIP has be the key type, not AES-CCMP. An attacker has to be proximate to sniff traffic and inject packets. The router has to be running Linux, like many Wi-Fi routers do. The router doesn't need to be compromised; there's a particular Wi-Fi packet sequence that's more predictable, and thus easier to use in the attack. Network QoS (802.11e/WMM) needs to be enabled as well./p pIf you can use the AES-CCMP key type (sometimes incorrectly called WPA2 by itself, but really the more advanced of two WPA2 methods), then you should! All corporations and other entities should already be using AES-CCMP, and with nearly all devices sold starting in 2003 supporting AES-CCMP, even home networks should be able to make that choice. /p p(A reader sent email asking if I wasn't mistaken: doesn't WPA2 only support the AES key? Yes, but it's also backwards compatible. If you have a WPA2 implementation, it may support TKIP unless the router maker has provided an option to lock into using AES only. Depending on the router, you might see "WPA, WPA/WPA2, WPA2" as a set of options, which corresponds to "TKIP, TKIP/AES, AES" for key types; or an explicit menu that lists key types after you select WPA or WPA2.)/p pCopyright copy;2010 Glenn Fleishman.

pa href="http://www.nytimes.com/aponline/2010/02/25/business/AP-US-On-the-Call-Cablevision.html?_r=1"strongWhile T-Mobile's UMA offering has been around for years, Cablevision may be trying something new:/strong/a Cablevision's COO mentioned in the company's earnings call today that the firm is testing phones that will switch seamlessly between cellular and Wi-Fi networks. That sounds an awful lot like UMA (unlicensed mobile access), a standard used for roaming by T-Mobile in the US and several carriers around the world./p pT-Mobile offers UMA because it lets them leverage other companies' broadband and its network of home and roaming Wi-Fi networks. T-Mobile operates relatively few hotspots now compared to when it was anchored by Starbucks, but the key to UMA is voice over Wi-Fi over a wired or wireless broadband connection at home./p pCablevision has an even easier time of it, because it provides its CT/NY/NJ Wi-Fi network only to users that subscribe to its home cable broadband service. So any phone it offers can carry voice over Wi-Fi at home over its cable network and outdoors over its Wi-Fi network. In the past, Cablevision has partnered with Sprint for wireless service. However, I'm unaware of any production UMA gear that would work on Sprint's network./p pThe notion of UMA is to reduce the cost to a carrier of subscribers while providing subscribers with more unrestricted minutes. T-Mobile's plans, for instance, offer unlimited domestic calling over Wi-Fi even for plans with modest numbers of cellular minutes. This keeps customers loyal and happy with a lower cost structure. Femtocells have the potential to offer similar advantages to T-Mobile's competitors, but none are being priced or marketed in that way yet./p pCopyright copy;2010 Glenn Fleishman.

Subscribers stand at 688,000. The company will spend about $3b in 2010 to get to its target of 120m people to whom service would be available. But if the network is to grow any bigger, more cash is needed./p pIn contrast, T-Mobile has crossed 200m already in upgrading its 2G network to add 3G, and it's ostensibly on track to something approaching ATT (233m) or Verizon (280m) levels. (Yes, those Christmas ads in which Verizon said it has the biggest 3G coverage are correctly, but the 50m gap is in small towns; ATT has the big markets.)/p pClearwire is leaning on Sprint for its fallback position, Sprint being the majority owner of Clearwire. If you get a combo 3G/4G USB modem or portable 3G/4G-to-Wi-Fi gateway, you can use 3G (up to 5 GB on Sprint's network) when away from a Clearwire area, and 4G in the footprint./p pBut Sprint has underspent on 3G. The company reports (the latest number I could find) 270m people passed with 3G emwith roaming/em. That's a critical point. Compare Verizon's native coverage map with Sprint's map, where Sprint shows gray for roaming, orange for 3G and tan for 2G: /p pimg src="http://wifinetnews.com/images/2010/Sprint-3G-map.jpg" alt="Sprint-3G-map.jpg" border="0" width="350" height="192" //p pAnd here's Verizon's, where dark blue is 3G, green is 2G, and yellowish is roaming:/p pimg src="http://wifinetnews.com/images/2010/Verizon-3G-map.jpg" alt="Verizon-3G-map.jpg" border="0" width="350" height="215" //p pSprint has the big cities, sure, but it doesn't disclose its non-roaming footprint, and it limits 3G customers to no more than 300 MB per month of roaming data, after which point it can choose to cancel a mobile broadband contract./p pbr / /p pCopyright copy;2010 Glenn Fleishman.

This is a blow for Row 44, which Southwest has picked, but for which we still have no details about financing: will Southwest back the installation, or Row 44 raise private capital? What will Southwest charge for service?/p pRow 44 has only a couple of non-announced airlines to pitch to in the US, and it's likely that airlines that haven't committed aren't planning to until there's more proof that Internet service produces happier customers who pay more for flights--as well as reasonable revenue from the service./p pAlaska will put service on 737-800 long-haul planes first, then roll out fleetwide. The press release is fairly frank in stating why the airline switched: "Their reliable, lower-cost equipment can be installed quickly, allowing Alaska Airlines to introduce Gogo service to our customers as soon as possible." /p p(You can stronga href="http://www.publicola.net/2010/02/24/mile-high-wi-fi-comes-to-alaska-airlines/#disqus_thread"read my full report on this/a/strong, including an interview with Alaska's VP in charge of this area, over at Publicola, a Northwest news and culture site.)/p pI had written in the past that Alaska's choice of Row 44 made sense because of the large number of over-sea routes the airline flies to Alaska and Mexico. However, Aircell will have service operating in Canada as a partner to a license winner at some point (this year?). /p pThat, combined with pointing some antennas at over the ocean, might allow reasonably continuous coverage between continental US routes and Alaska. Mexico is another story, but Aircell hopes to have the same deal Verizon Airfone had in Mexico and the Caribbean to allow use of the same spectrum for which it has licenses in the US./p pAlaska said in the press release, "To ensure the service is available to the airline's namesake state, Aircell will expand its network to provide Gogo Inflight Internet service on flights to, from and between key destinations in the state of Alaska."/p pAircell's Gogo Inflight Internet is on over 700 planes at present. I expect it'll hit about 1,500 planes this year, although the pace of installation could speed up if airlines are happy about uptake and revenue./p pCopyright copy;2010 Glenn Fleishman.

pa href="http://www.att.com/gen/press-room?pid=4800cdvn=newsnewsarticleid=30358mapcode="strongATT didn't want to let T-Mobile steal the initiative on HSPA 7.2:/strong/a I missed the 5 January 2010 release from ATT that explained the firm had updated its mobile broadband network to HSPA 7.2; T-Mobile said last week its entire footprint is now HSPA 7.2 as well. /p pATT said last year that it would roll out the 7.2 update--which offers a raw data rate of 7.2 Mbps including network overhead--to most sites by the end of 2010, and its entire footprint by 2011. In Europe, HSPA 7.2 networks seem to operate in a broad range: users report regular performance from about 1 to 4 Mbps. It's unclear how carriers will provision, throttle, or shape HSPA 7.2 here./p pATT's announcement coming early made it seem like it might have leapfrogged T-Mobile, given that ATT has more metro areas covered with 3G, and has already sold a fair amount of HSPA 7.2 enabled gear, such as the iPhone 3GS. But that's not the case./p pATT wasn't trying to pull a fast one, even though it was marketing this move as an enhancement. In the 5 January press release, the company makes it crystal clear that it's upgraded the software to allow HSPA 7.2 even though it doesn't have the necessary backhaul improvements in place to make the network actually faster./p pThis is refreshingly frank. The release said that the software update would improve network quality even before backhaul improvements that are slated for this year and next are in place to provide increased capacity. I'm sure ATT is correct. More efficient use of the local link among capable devices means less wasted air time and less congestion, which allows better packet shaping and prioritization. I'm sure local network links function far better at 7.2 Mbps, even if the backhaul can't support the uplink side./p pSix cities have the promised backhaul improvements underway: Charlotte, Chicago, Dallas, Houston, Los Angeles, and Miami. The release says the updates are site by site, which means you could experience different speeds driving around the same city while the upgrades are in process./p pT-Mobile, on the other hand, has been building its fresh HSPA network with the notion that backhaul for HPSA+ (21 Mpbs in its version) will be flooding the grid, and thus has the advantage of not having to deal with legacy installations. It has been able to make all its choices about towers with the notion that each base station may need 20 to 100 Mbps of backhaul. (These are guesses; the company hasn't released that information.)/p pI continue to find it ironic that wireless networks rely so heavily on wires./p pCopyright copy;2010 Glenn Fleishman.

pstronga href="http://www.pcworld.com/article/189413/tmobile_usa_to_sell_first_hspa_usb_stick.html"T-Mobile is trying to seize its HSPA+ momentum:/a/strong The fourth-ranked carrier by subscribers in the US, T-Mobile is trying to establish an advantage through its fast deployment of 7.2 Mbps HSPA followed this year by 21 Mbps HSPA+. But you need the proper hardware to go with that faster network, and today's announcement of the webConnect Rocket USB Laptop Stick (no pricing yet) is signaling more to come./p pThe modem won't ship until March, and HSPA+ is available only in Philadelphia so far. T-Mobile said it will focus on bringing HSPA+ to the coasts first, and then move inland. In an interview, T-Mobile said it would have the "majority" of its footprint upgraded to HSPA+ in 2010./p pThe company also stressed its work on backhaul improvements, a bane of the mobile broadband industry. You can have as much bandwidth as you want on the local link between devices and the tower, but then you have to offload that to a core network. Many cell sites had paltry backhaul and it was difficult to bring in more. T-Mobile promised me more details soon, but the company recognizes that you can't advertise a raw rate of 21 Mbps--probably 5 to 7 Mbps to individual users--without having invested on the backside, as ATT has learned to its high discomfort./p pT-Mobile would like bragging rights for having the fastest network, although even with the latest market rollouts, it's still covering just over 200m people in approaching 300 cities. ATT, by contrast, even with its smaller-than-Verizon 3G footprint has 350 metro areas (not just cities) with 3G service, although ATT doesn't seem to discuss people passed with service./p pI keep pressing T-Mobile on its 5 GB monthly bandwidth limit included with all its 3G plans as it discusses HSPA+ plans. The 5 GB limit was a quiet or explicit limit before 3G networks could routinely deliver over 1 Mbps (back in the EVDO Rev. 0 and GPRS/UMTS days), and now it seems quaint even for EVDO Rev. A and regular HSPA./p pWhy give people HSPA+ when, at full speed, they could use up their entire monthly allotment in just over two hours (assuming 5 Mbps average speed)?/p pSo far, T-Mobile just repeats that most of its 3G users consume just a fraction of the 5 GB to which they are entitled each month./p pCopyright copy;2010 Glenn Fleishman.

As no obvious catastrophe has shown itself, "I would tend to think there's nothing there."/i/p pThat's where I keep coming back to Occam's Razor related to EMF exposure. People who claim effects say that there are tens of millions of more people obviously suffering from effects, but the research (described quite well in stronga href="http://www.latimes.com/features/health/la-he-electromagnetic-syndrome1-2010feb15,0,801515.story"the second LA Times article/a/strong) doesn't back this up./p pI would argue that electrosensitivity has been well and truly put to bed, and that means that the effects should show up in cancer studies, given the use of cell phones for longer than 10 years by a significant population. That's not showing up in general work, nor in studies like Interphone, which I wrote about a few days ago./p pOne set of analysis of a segment of the Interphone work showed a possible correlation between use of a cell phone for more than 10 years and, in those people who had certain kinds of brain tumors, the tumor appearing on the same side of the head as those who used a cell phone mostly on that side of the head./p pBut the researchers in that study noted quite clearly that there's a recollection bias. If you have a tumor next to your right ear, and researchers say 10 years or longer ago did you mostly use a cell phone on your right side, the expectation is that people tend to say they used the damaged side of the head./p pI remember the concerns in the early 1990s about ELF/VLF (extremely and very low frequency) EMF produced by CRT-based computer monitors. Studies abounded that showed risks, especially from Sweden, but when you read the studies you found that exposing chicks to radiation at huge multiples of what normal exposure was, or that retrospective studies asked people detailed questions to correlate usage at old video display terminals (VDTs) and miscarriage, without eliminating other risk factors. The research was basically garbage, no link was ever found, and there were no bulges in epidemiology related to CRT use. It was forgotten./p pI expect in time the same thing will happen here. With no smoking guns for cancers, no long-term health effects found, and electrosensitivity isolated again and again from the presence or absence of EMF, in 10 years we won't be talking about this at all./p pCopyright copy;2010 Glenn Fleishman.

Students in Vail, Arizona, ride on a Wi-Fi bus, which uses a mobile broadband router (stronga href="http://www.autonetmobile.com/"Autonet/a/strong) to power their laptops en route./p pThe longer battery life in laptops, which have become ever cheaper, coupled with greater coverage of the fastest flavors of 3G, mean that students can actually get real work done that requires an Internet connection.

pa href="http://www.gq.com/cars-gear/gear-and-gadgets/201002/warning-cell-phone-radiation?currentPage=1"strongI finally read the GQ piece that's been widely cited as "proving" the dangers of electromagnetic radiation produced by cell phones:/strong/a It's a piece of crap. The article spends the vast majority of its time looking into corporate conspiracy to keep news about cell-radiation issues silent, and giving a forum to anecdote and studies that have since been shredded to pieces for lack of rigor. /p pI don't doubt that corporations have worked hard to prevent studies from coming out that would show any correlation of risk, because that's a common pattern for large corporations. That said, there's such a huge amount of data, and studies with such large cohorts, it's hard to believe that companies were successful in "suppressing" such data./p pThe reason I even address GQ, provider of fine investigative journalism that it is not, is that a Santa Fe resident was nearly hauled out of a city council meeting after arguing against installing more wireless base stations--perhaps for cellular. The Los Alamos National Laboratory physicist Frank Bruno is a href="http://www.santafenewmexican.com/Local%20News/No-decision-on-Wi-Fi--after-heated-debate"strongpictured in this article holding up this awful GQ story/strong/a as part of his proof that microwave radiation is deadly. So it can't be ignored./p pI'm going to focus on two elements in the story, because it's mostly full of farragoes and nonsense. /p pThe first is the a href="http://www.springerlink.com/content/x88uu6q103076p53/fulltext.html"strongInterphone study/strong/a, the best science cited in the article. Thousands of people with certain cancers that seem likely to result from close proximity to cell phones were selected, interviewed, and results compared against interviews with controls selected from the population at large in those countries. Despite the huge amount of effort to recruit subjects, just under 8,000 participants with cancers were interviewed (several hundred per country) and under 7,000 controls. /p pBut studies resulting from Interphone don't say what the GQ article alleges. The author writes, "Interphone researchers reported in 2008 that after a decade of cell-phone use, the chance of getting a brain tumormdash;specifically on the side of the head where you use the phonemdash;goes up as much as 40 percent for adults." That's not inaccurate, but it leaves out 100 percent of the context./p pThe a href="http://www3.interscience.wiley.com/cgi-bin/fulltext/114072761/HTMLSTART"strongstudy itself/strong/a (International Journal of Cancer, Vol 120, Issue 8, 2007), which perhaps the GQ author didn't read, notes, "The results of our analyses do not provide consistent evidence for increased risk of glioma related to use of mobile phones. We did not find indications of increased risk related to regular mobile phone use overall, or in the majority of the subanalyses based on various exposure characteristics. The most exposed group (the highest 10% based on the exposure distribution among controls) did not show an elevated risk of glioma."/p pThe study authors do note that in one subset of analysis that looked at use of a cell phone preferentially on one side of the head or other--as reported by subjects, and covering 10 years and longer--"was associated with significantly increased risk of glioma and there was also an increasing trend with years since first use on the ipsilateral side."/p pThe study authors note that there's likely strong reporting bias on both use and which side a person regularly talks on. The conclusion about the higher rates: "This may be due to either chance or causal effect or information bias, i.e. overreporting of mobile phone use on the affected side by the cases with brain tumors."/p pThe a href="http://www.iarc.fr/en/research-groups/RAD/current-topics.php"strong"latest update" on Interphone research/strong/a--8 October 2008--citing this and other studies concludes fairly strongly that there are a few areas that should be looked at further, but that the data generally supports no pattern or revelation about a connection between cancers studied and cell phone usage patterns. /p pI won't go into every other item mentioned in the GQ article, because we have had discussions at this site over the years on these subjects./p pWhat I will mention is that none of the vast array of credible information contrary to the conclusions of this author and, obviously, GQ, were mentioned except in passing. This includes the now dozens of well-conducted, published studies that find no connection between a signal and "electrosensitivity," and some of which show the presence of measurable, severe symptoms whether a signal is present or absent./p pThe second element simply reveals the poor knowledge of the reporter and factchecking employed by GQ. The article notes,/p piIn the summer of 2006, a super-Wi-Fi system known as WiMAX was tested in rural Sweden. Bombarded with signals, the residents of the village of Gouml;tenemdash;who had no knowledge that the transmitter had come onlinemdash;were overcome by headaches, difficulty breathing, and blurred vision, according to a Swedish news report. Two residents reported to the hospital with heart arrhythmias, similar to those that, more than thirty years ago, Allen Frey induced in frog hearts. This happened only hours after the system was turned on, and as soon as it was powered down, the symptoms disappeared./i/p pSo where did this come from? I'd never heard of this. And WiMax wasn't commercially available except in test form in 2006. What un-cited "Swedish news report" covered this?/p pI used The Google to find out. First off, it wasn't summer, it was February 2006. Second, the report a href="http://www.theinquirer.net/inquirer/news/1038429/swedish-town-blighted-wimax"strongseems to have originated at the Inquirer/strong/a on 12 June 2006, which links to an Australian bulletin-board on ISPs, which a href="http://forums.whirlpool.net.au/forum-replies-archive.cfm/537044.html"stronghas a post by a reader named Brains/strong/a, which links to a 23 May 2006 report from Sweden's STV network. /p pThat report, which is neither available at the original URL, and which I could not find by searching on stories on Gouml;tene (of which there are many), is paraphrased here by someone who backs the electrosensitive theory. The story apparently came from a "current affairs program 'Debatt,'" rather than from public-health officials or other sources. Nor does the Australian link mention that the system was shut down; nor can I find any evidence it was./p pFollowing this further, I a href="http://omega.twoday.net/20060531/"strongfound on an anti-EMF-use site/strong/a that the Debatt program is, well, a debate: two Swedish experts pro and two con as to whether EMF poses a threat to health. The usual Swedish sources (Mona Nilsson and Olle Johansson) took the view that there was a threat to health. The Gouml;tene story was apparently a lead-in, and it's unclear whether the guest representing the Swedish government provided any refutation to the details./p pThe GQ author follows this up by noting, "Today, Sprint Nextel and Clearwire are set to establish similar technology across the U.S., with a $7.2 billion government broadband stimulus speeding the rollout."/p pDozens of WiMax systems are up and running in the United States, and hundreds worldwide (some quite modest). The power output of WiMax is comparable to cellular, although using mostly different frequencies. The notion that WiMax is something new and different than 3G from a signal perspective or "electrosmog" view is nonsense./p pThe GQ article doesn't advance any knowledge in this area, lacks rigor, and again gives credence to what is palpably a false cause for those suffering from real symptoms--ones that have been repeatedly shown to be unrelated to "cell radiation."br / /p pCopyright copy;2010 Glenn Fleishman.

In some cities, like Lompoc, Calif., which launched efforts around the same time, cable and telco firms stepped up and made the Wi-Fi networks nearly unnecessary for indoor use./p pChaska.net still operates, however, although the operation is servicing debt and not accruing capital, which is the goal; current expenses aren't mentioned, but the setup costs were $3.3m, including $1m in fiber expense, the article in the Chaska Herald reports./p pThe network doesn't deliver just Wi-Fi in the city, but is part of a backbone that brings point-to-multipoint wireless broadband to smaller towns nearby, and to 36 business customers in town./p pChaska has a fairly stable base of about 2,100 subscribers, the article notes, expecting just a net add of 60 per year in the future. That's a huge uptake for a town that in 2000 has 24,000, which likely means 5,000 to 8,000 households. Subscriptions would likely be higher except the ability to get a signal isn't uniform across the town, which is true of all wireless systems, but Wi-Fi's low power limits makes it particularly susceptible./p pChaska was used by Tropos as its poster child when that firm was out trying to persuade firms and cities that high-quality "mesh" networks could be built for indoor and outdoor service using 20 to 25 nodes per square mile. Chaska never lived up to its marketing in those early days, and, Tropos at one point (apparently at its own cost) swapped out all the initial nodes installed in the city.

That puts them at 2012 on this scheduled for full-fleet rollout. /p pCost still hasn't been set. Of course, people would prefer to pay nothing, but Southwest hasn't been consistently low-operating-cost and low-fare by guessing wrong on what people will pay./p pCopyright copy;2010 Glenn Fleishman.

pimg src="http://wifinetnews.com/images/plane.jpg" align="right" border="0" hspace="5" /strongMy recent trip to San Francisco for Apple's iPad launch gave me some hands-on time with Gogo Inflight Internet:/strong Despite writing about in-flight Internet for nearly nine years, I have rarely had the chance to experience it. My heavy flying days--tens of thousands of air miles a year--ended back with the dotcom boom in 2001. I flew a a href="http://wifinetnews.com/archives/2004/09/up_in_the_air.html"strongConnexion by Boeing test flight in 2004/strong/a with other reporters out of Seattle's Boeing Field that didn't even use the production flavor of that service; and I was on board a href="http://wifinetnews.com/archives/2008/11/live_from_virgin_americas_inaugural_wi-fi_flight.html"strongVirgin America's launch of Wi-Fi in 2008/strong/a. Other than that, nada!/p pa href="http://www.flickr.com/photos/jeffcarlson/4313567798/in/set-72157623305966174"img src="http://wifinetnews.com/images/2010/glenn_va_jlc.jpg" alt="glenn_va_jlc.jpg" border="0" width="159" height="240" style="padding-left: 5px" align="right" //aSo it was rather exciting to be able to have a real-world experience with Aircell's Gogo on the way down and back to San Francisco--even better, I was able to snag seats in an empty exit row on the way down and had an empty middle on the way back. The flights are 100 minutes in the air, with perhaps 80 to 85 of those above 10,000 feet. I had previously a href="http://www.gogoinflight.com/gogo/splash.do;jsessionid=2A2317A1AE31DE3D169759BF4597EC18.node2?execution=e1s1"strongset up an account with Gogo/strong/a, something Aircell advises because it removes the friction in the air from starting up a session. You can store a credit card for billing as part of account setup. /p pConnecting to the network was no trouble for me, but my colleague Jeff Carlson couldn't initially pull up the redirection hotspot page. We checked his settings, and found he had hard-coded his DNS servers to OpenDNS. This is a good idea in general--faster DNS, phishing protection, and search result redirection--but it causes trouble when there's a hotspot redirection page. He removed his DNS server settings and then got the splash page./p pSetting up a session is straightforward: you choose a plan, such as a day or month pass, and then pay for it. We had complimentary codes, and entered those in the checkout stage./p pa href="http://www.flickr.com/photos/glennf/4309342916/in/photostream"img src="http://wifinetnews.com/images/2010/apple_reflection_va.jpg" alt="apple_reflection_va.jpg" border="0" width="240" height="180" align="left" style="padding-right: 5px; padding-bottom: 5px" //aService was reliable and consistent for nearly the whole way down and back. I used the Web, Dropbox, an RSS reader, email, screen sharing (VNC), Twitter, iChat, and other services and protocols without any problems. A test at one point during one flight of bandwidth showed precisely 256 Kbps of downstream (Internet to me) and about 300 Kbps upstream (me to the Internet). The service is clearly throttled and provisioned, and the exact 256 Kbps (two to the eighth power) figure shows perhaps how precisely so. Gogo has about 3 Mbps of raw bandwidth to divvy up./p pIt was definitely both useful and a pleasure to have Internet access nearly continuously during this particular trip. Jeff and I were trying to stay up to speed and get prepped on the way down, and then were writing and posting material at the Apple event venue, at a Starbucks afterwards, at SFO, and then from the plane itself. I rarely have to keep a constant stream of activity like that, but I work for myself./p pJeff and I conferred about the price. If were paying for it, we likely would not have paid the $9.95 for the SEA-SFO leg, because we could have read a book or slept. It was useful, but not critical. The ten bucks for the SFO-SEA would have been a no brainer, as we had plenty of work to do on that flight./p pNow if only the people in the seats in front of Jeff and I hadn't leaned back so far we could barely open our laptop covers. Perhaps the iPad will solve that problem./p p(Disclosure: Aircell gave me free codes to use to test the service on these flights, but this post is not sponsored, nor did Aircell see this post or have any input into it. I paid the listed fare for the flight. As you can tell from other articles on this site about Aircell and Gogo, I don't pull my punches.)/p pCopyright copy;2010 Glenn Fleishman. All rights reserved.

pstronga href="http://www.apple.com/ipad/specs/"Apple's 3G iPad models will come with two unique aspects: only unlocked, no-contract services:/a/strong It's not surprising that Apple will have Wi-Fi only and Wi-Fi plus 3G variants of its new iPad mobile device. Rather, it's that Apple finally got its demands met about how consumers will control the relationship with cellular carriers./p pThe iPad will come with a stronga href="http://www.pcmag.com/article2/0,2817,2358489,00.asp"micro SIM/a/strong, a new tiny form factor for SIM in mobile devices that's not yet in real use, as far as I can tell. (I had never heard of it before today, even though it's a settled 3GPP format.) Steve Jobs said it will be simple to swap out SIMs from other carriers, so that the US version of the 3G iPad will "just work" in most cases outside the US. It won't be until June or July that Apple has carrier relationships for direct sales and data plans other than in America./p pThe unlocked iPad will be coupled with two data plan options from ATT, neither of which requires a contract or (as far as I know so far) any cancellation penalty. ATT has some services now that you can turn on or off on demand, such as navigation./p pThe 250 MB/mo. plan is $15/mo; the unlimited plan is $30/month. While you might scoff at 250 MB, the iPad will have the same limitations as the iPhone in terms of downloading and storing stuff over the Internet, so outside of purchasing movies, the biggest 3G drain will be streaming video. Because the iPhone OS doesn't support Flash, streaming video must all be embedded H.264 format or accessed via the YouTube app or other applications./p pI'm calling the 250 MB/mo plan "your mother's plan," because it's most likely to appeal to people who won't be heavy 3G users, and will mostly use the device over Wi-Fi at home or at hotspots. However, they will want the flexibility of having 3G available wherever when they carry the device with them./p pThe iPad still is slated to have the disappointing pairing of UMTS for upload (384 Kbps) with HSDPA for download (ostensibly HSPA 7.2 as with the iPhone 3GS); this detail is noted on the stronga href="http://www.apple.com/ipad/specs/"Tech Specs page/a/strong for the iPad. The iPad will likely be a heavier producing device, especially given that there's a camera connection kit (USB or SD card reader) that will let you suck photos directly into the iPad. These will sync with iPhoto when you return to a Mac (or through other means specified in iTunes on a Mac or under Windows), but uploading photos during a trip will certainly be desirable, and limited over 3G networks to the paltry 384 Kbps rate./p pI should note, of course, that the iPad will have 802.11n support, but it's unknown to me yet whether this will be a single-stream radio, which would use less juice and thus be more sensible in a device intended to have a long battery life, or a two-stream 802.11n adapter, which will drain it faster. Apple uses USB for syncing large amounts of content, and doesn't provide over-the-air sync for anything directly. (You can use its MobileMe service to sync calendars and contacts.)/p pThat means that the gating factor on most networks will be the Internet connection, not the wireless LAN. Having a 50 Mbps or so top rate with 802.11n single stream won't really be a clog on the iPad's abilities./p pCopyright copy;2010 Glenn Fleishman. All rights reserved.
