BART Wi-Fi Plan Not in Jeopardy over Funding
The Examiner reports that Wi-Fi Rail may be in trouble about signing contract with BART, raising money: But Wi-Fi Rail says it ain't so. Cooper Lee, the company's head, just called to let me know that the focus of the article was a bit off. In an earlier version of this item on Wi-Fi Networking News, I wrote: "Wi-Fi Rail spoke bluntly to the San Francisco Examiner five months after the board of the Bay Area Rapid Transit plan had approved contract negotiations for a full-blown installation. The negotiations aren't finished, and the tight credit market means it might take months after signing a deal for Wi-Fi Rail to raise the necessary funds." Lee said, however, that they've already raised the money they need for the next 12 months, and that they believe they'll sign a contract soon. Lee said that the company needs to spend a total of $20m over 24 months, but that $9m are in equipment leases, which is simple financing. He also said that much of the negotiation with BART was ensuring that the ramp-up for customers and revenue was fair relative to the fees paid to BART; BART doesn't want Wi-Fi Rail to be saddled with obligations they can't meet before customers appear, which makes sense for a transit authority looking many years into the future. They'd rather have a stable than a squeezed provider, obviously. Lee said the company is moving forward with the expectation they'll be able to start work soon, hopefully before Christmas....

Wee-Fi: iPhones Get Free Wi-Fi; Another Loiterer Arrested
AT&T finally gets off the dime--sorry, quarter--and opens its Home network to iPhone subscribers: AT&T had promised some kind of Wi-Fi deal for its legions of iPhone subscribers for more than a year, and at least twice posted information that was premature. Yesterday, the company pulled the trigger. The mechanism to get service at about 18,000 domestic hotspot locations--mostly McDonald's and Starbucks--is complicated. You join the network, visit a gateway Web page, enter your cell phone number, and wait for a (free) text message. The message contains a link to a secure site that, when followed, activates 24 hours of access, but only at that location. You can apparently activate service at as many locations as you want in a single day. British lad arrested for kiping Wi-Fi: A 16-year-old was arrested for breaking the encryption on his neighbor's Wi-Fi network. The arrest was apparently "canceled" later--I don't understand British jurisprudence enough to get this part--with the boy's father fileing "a complaint for unlawful arrest and detention," The Register writes. The misuse was discovered because the fellow's network name was set to be his own (by his father), and this showed up in the Wi-Fi gateway's list of DHCP assignments....

UWB Retreats?
Ultrawideband's future as personal area networking technology seems dim: With leading UWB chipmaker WiQuest going out of business last week, with very few devices on the market two years after UWB was supposed to have its big introduction, and with apparent little interest in that changing, it's hard to see how UWB winds up in printers, cameras, laptops, desktops, and hard drives. It's not that UWB will disappear (likely): the technology has other uses, some niche, and some as mainstream as being one of the options for wireless high-definition streaming as an HDMI cable replacement. Alereon, another chipmaker, announced today that it would acquire Certified Wireless USB assets of Stonestreet One, a firm involved in tests of UWB in mobile devices, like smartphones. Alereon's CEO Eric Broockman would like to spin the story, as he writes in his blog, that there's a very long timeframe for most new technology adoption, and that market leaders are rarely the first to capitalize on the advantages. Right. But with Intel, a leading UWB backer, seemingly having shifted its interests; with a leading UWB chipmaker gone; with just Lenovo and Toshiba offering any kind of UWB option; with no word on any UWB-enabled peripherals going into Christmas; well, I could go on. Broockman is certainly correct that there's always a shakeout, but I'm surprised how long UWB has been under development without any deep niche adoption. Early flavors of Wi-Fi were in devices sometimes years before standards were ratified. Airgo, for instance, had its MIMO flavor of 802.11 on the market long before competitors, and it was acquired by Qualcomm (disappearing from sight, but not unsuccessfully in terms of the investors' interest or in spreading MIMO as an essentially mandatory element of 802.11n). I wrote more about this at Ars Technica along with the historical background....

Wee-Fi: Enterprise 802.11n Rated; Au. U Illegal Use-Fi; Micro-Fi: Shorts on Cities
Enterprise 802.11n gear has up to 10 times throughput of previous generation: Network World put four equipment makers' enterprise 802.11n gear through its paces, and found enormous improvements over 802.11g. However, as I've seen repeatedly with consumer-grade gear, maximum throughput is limited by internal system resources, like the system bus. 802.11n offers such a vastly higher rate of speed that firms and their engineers clearly need to move up yet another notch in designing equipment that can take full advantage. Network World examined Aerohive, Bluesocket, Motorola, and Siemens access points. Aruba, Cisco, and Trapeze declined in various ways to participate, which is a shame. University of North South Wales shocked--shocked!--to find illegal downloads occurring: This Australian university may turn off its free Wi-Fi because students are acting like students, downloading what the IT director calls illegal content. The university fines students up to A$1000 for illegal downloads. Micro-Fi round-up: Hillsboro, Ore., gains Wi-Fi through effort of local resident with Meraki boxes; Birmingham (UK) has extremely limited free-Fi, choosing to have residents, visitors pay for access via BT, criticized by Flickr's visiting community manager; Niagara Falls gets 12 square blocks of free wireless; Portsmouth, NH, accepts $350K in Cisco gear for downtown service with few strings attached....

Backwards, O Hands of Time: Atheros Single Stream
Atheros thinks single-stream 802.11n has potential to replace 802.11g: Atheros has introduced the Align, a family of chips that use a single antenna to bring some 802.11n advantages without the spatial multiplexing, improved receive sensitivity, further transmit range, or antenna diversity, among other characteristics. The company told EE Times that they wanted to get beyond 802.11g for future devices to bring the advantages of newer designs. This should allow G prices with some improved N features. This won't break 802.11n compatibility, as 802.11n can hear a single spatial stream just as well as it can multiple ones. In fact, 802.11n provides the flexibility to have multiple streams sending the same data redundantly, which is what Quantenna has opted to do with its consumer gear--sacrificing raw speed for resilient performance. Atheros is claiming 50 Mbps in TCP throughput with 20 MHz channels and 107 Mbps with 40 MHz. This isn't out of line with the base raw symbol rates in 802.11n (65 Mbps instead of 54 Mbps). TCP throughput still has overhead, of course, so it's likely that single-channel N will be about twice as fast as the 20 Mbps or so 802.11g could achieve....

Wee-Fi: More Geolocating with Google, Boingo Ups Count, Nationals-Fi, Free AU Mickey D-Fi
Google announces update to Geolocation API with Gears: The company's browser engine allows extending JavaScript beyond what's possible by itself, and their library for geolocation (finding oneself through information a Web page can query the browser for, in this case with your permission) now includes Wi-Fi positioning data. This is true for both laptops, where the Geolocation API now works, and mobile devices that support Google applications. Google wouldn't say how they've developed their own Wi-Fi location database. Read my full account at Ars Technica. Boingo says they've broken 100,000 (103,749, to be exact): The Wi-Fi aggregator signed up 2,600 hotspots from Telefonica in Spain and Argentina, while sharing 7,000 of their locations with customers of the telco networks. The 2,200 Spanish locations are online now; Argentina's 400 follows. Last month, Boingo folded in 1,100 Swisscom locations, typically supremely high priced even in Europe for stand-alone usage. Baseball team gets lots of coverage for future add-ons: The Washington Nationals installed an 802.11n network from Meru at their ballpark, and I've seen articles all over about both their choice of N as well as their plans to add Wi-Fi-accessible instant reply clips for fans, an ability for fans to send in photos and text messages, as well as internal applications. The installation sounds cheap: $280,000 for 200 access points and all the planning and deployment. So far, the network has been used for wireless ticket scanning to add capacity where needed at gates, and to provide service for reporters and photographers. McDonald's service goes free in the antipodes: Australian McDonald's stores will offer free Wi-Fi starting in December. By March 2009, 720 outlets will be available for use at no cost through a partnership with Telstra. McDonald's charges for service in the U.S. at its 10,000 equipped company-owned and franchise restaurants, but has a variety of partnerships and bundles that enable many users to access the network at no cost....

Fon Raises Alien Price to 5 Dollars, Euros
Fon ups the ante on joining its network by raising its daily connection price to $5/€5 for "aliens": The Fon network of what they claim is nearly 200,000 active locations is all about participation. You can be a participant (a Fonero) and charge or not, but anyone with an active Fon hotspot gets free roaming on the entire network. Fon charges for access regardless of whether someone collects part of the fee (a Bill, not available in Japan, Russia, or the UK) or opts not to (a Linus). The fee affects Aliens, those who aren't running Fon hotspots, and thus aren't contributing to the network's size. But $5 or €5 is a lot in most countries, and buys you a fair amount of time in an Internet cafe, making VoIP calls, or an hourly or daypass on a Wi-Fi hotspot network. At 5 monetary units, doesn't that push Aliens to finding a free or cheaper alternative? The only explanation I can find of the price change is on the German Fon blog. That entry explains that they're trying to focus on building a community, and that raising the price should encourage more people to participate in sharing their Internet access. That doesn't square precisely with their goal of making money, though, because there's no monetization outside of Aliens paying fees to use the network. Like airport parking lots, you can only raise prices so far until people find cheaper, even if less convenient, alternatives. [Thanks to Klaus Ernst for the price increase alert!]...

Positive Response to WiMax Launch in Baltimore
The New York Times and BusinessWeek are bullish on the Sprint Xohm launch in Baltimore: Two veteran tech reporters, who have had time to see it all and be cynical about it all, are fairly positive about the Sprint launch of WiMax. This is the first city-wide launch in the U.S. for regular signups, and one of the largest networks now operating in the world. (As far as I can tell, Seoul's WiMax-compatible WiBro network is still not designed for 100-percent city coverage, but is boutique.) Bob Tedeschi at the Times found solid performance wherever he tested, but he notes the caveat that the network is nearly empty at the moment. While comparing Sprint's promised up to 4 Mbps down and 1.5 Mbps up, he uses an outdated number for AT&T's 3G network. AT&T used to give out the numbers he states, but as of their HSUPA upgrade a few months ago, they claim 700 Kbps to 1.7 Mbps downstream and 500 Kbps to 1.2 Mbps upstream. I haven't had the opportunity to test these rates, but this is their current claim, not what Tedeschi reported. Tedeschi checked out various adapters and devices, including the Nokia N810 WiMax Edition ($500) that just went on sale. He had problems with video playback, but that could have been the network or the phone's operating system or the site he was accessing. He did like the quality of VoIP calls. BusinessWeek's Stephen Wildstrom was more enthusiastic, seeing rates of 3 Mbps down and 500 Kbps to 1 Mbps up, and was able to watch Hulu.com streaming content as a passenger in a moving vehicle. Both reporters note that WiMax seems to improve on Wi-Fi and cell data service in both speed (as 3 Mbps is faster than most Wi-Fi hotspots, and much faster than the average of most 3G networks), availability (for Wi-Fi), and cost (for 3G). Subscriptions are a little complicated: $30 for roaming, $35 for home, $45 for a combined plan, and $60 for multiple devices, if I have all that right. Subscribers also need to buy a dongle, card, adapter, or CPE (home bridge), which seem to run under $100. Adapters will eventually be built into Intel-designed laptops....

Wee-Fi: Quantenna In Depth, WalkingHotSpot, T-Mobile's 3G Footprint, Devicescape's Easy Wi-Fi. Boingo on Moto Q 11
In-depth on Quantenna: For Ars Technica, a great technology site for which I recently started a regular writing relationship, I wrote up a long interview with Quantenna's founder, in which I examine more detail about how they achieve 1 Gbps with standard Wi-Fi. The secret? Lots of radios, lots of antennas, deployed in what they say will be an inexpensive fashion. Could shake up the market, even if Quantenna isn't the winner, but they appear to have a real lead over established chipmakers. Taproot releases WalkingHotSpot: Yet another software package for turning certain smartphones into Wi-Fi hotspots using the built-in cell data service as backhaul. The $7 per month or $25 per day software license turns on the service on Symbian S60 or Windows Mobile phones. There's a 7-day trial, too. Only WEP security is supported because ad hoc mode is used; infrastructure mode isn't available. T-Mobile clarifies 3G availability: T-Mobile must have gotten tired of explaining that 21 markets doesn't mean 21 cities. For instance, in Los Angeles, they note via email, that market includes Anaheim, Irvine, Long Beach, and Pasadena. For clarity's sake, they're now saying 92 major cities across 21 markets now; Wednesday, with the G1 with Google smartphone launches, they'll be up to 95 cities. They say by the end of November, 120 major cities. Devicescape expands platforms, renames software: Devicescape announced its availability on HTC phones, dominate in the Windows Mobile market worldwide; on a Fujitsu phone sold in Japan by DoCoMo; and as part of DeFi, a global VoIP over Wi-Fi calling service that's soft launching. The company also said that it's software will now be named Easy Wi-Fi across the board, and they've split their platform approach into devices, laptops, and handsets, to make it simpler for development and licensing by partners. Easy Wi-Fi is now available on a pretty large selection of smartphones, including those made by Palm, running Windows Mobile or the Nokia E60 platform, the iPhone and iPod touch, among others. Boingo adds Moto Q 11: Boingo's software for connecting to its aggregated worldwide hotspot network is now available on the Moto Q 11 phone in the Boingo Mobile flavor ($8/month worldwide). All owners of this model can get a free month of service to test it out....
