Firefox 3.5 has shipped with location finding turned on: The latest release of Firefox includes by default the option to use a computer's IP address and, if available, a scan of nearby wireless networks to provide a location to Web sites that use appropriate JavaScript to request a position. Users can opt out when asked, disable location requests for a site, or disable location requests entirely. However, "ask for permission" is on by default.
Firefox is using Google Location Services, which is a combination of cellular tower data that the company has assembled along with some unknown method of collecting and locating Wi-Fi hotspots, much as Skyhook Wireless has been doing for years. Likely, Google gathers this information as it drives the streets for Google Maps.
Mozilla's location mascot
With several tens of millions of smartphones (iPhone and Android-based models mostly) and handhelds (almost entirely the iPod touch) providing location data through various combinations of Wi-Fi, cellular trilateration, and built-in GPS, getting a location instantly may not seem that interesting any more on the desktop or laptop.
But it still seems to have a place. Location has two purposes. One is to find oneself, an existential proposition if I ever heard of one, because you don't know where you are. But the other is to identify your location to someone else because you want them to know where you are for some purpose: personal, commercial, or otherwise.
In the latter category, having location built into a browser lets Web sites offer rich location data even when you're at home. Aren't you frustrated about having to type in repeatedly your street address for work or home to find something in proximity, such as with a store locator? Wouldn't you like to have Web applications that automatically took advantage of your location by providing relevant data you didn't need to look up separately? (There are already plenty of utilities for Mac OS X and Windows that can use location to change system-wide settings, such as backlighting, r to launch or quit programs, or change your instant messaging status.)
Smartphones work best at giving you instant proximity data when you're out and about, because there's zero startup time. You take the phone out, hit the wake button, and run a program. I've become addicted nearly instantly to Urbanspoon after installing it on my iPhone because it tells me with incredibly little fuss what's near me. I needed to find a place to take my older son for lunch, and his appetite doesn't mesh well with restaurants. He agreed to eat a hot dog. I punched hot dog into Urbanspoon and within a few seconds found a suitable place. (He did eat the hot dog, and about a million fries. We went to Schultzy's.)
A laptop is a much more tedious operation for a spur-of-the-moment check. You have to dig it out, find a surface on which to balance it or hold it in your hand, wake it or power it up, find a network connection (unless you have a cell data card), find the Web site you want, and so forth.
The flip side is that when your desktop or laptop is already running, and you need a location-based piece of information, it's far more convenient to get a full, fast browser experience, with a real keyboard you can use to type in what you're looking for.
We'll see how it pans out. Sites have to enable location services, which should work identically in Firefox 3.5 and Chrome, and which will likely spread to other browsers over time if there's interest. (I suspect indexing software can identify if the JavaScript used on sites contains location calls, and smart people will use that to quantify geolocation-aware sites.)
There has to be a pull from sites to make people interested in and expecting to use location services. If all that sites do is enable store locators via this option, I can't see much interest developing over time. But if sites can find unique ways to let the browser plus location combination provide the social networking or sheer utility of many smartphone apps, then the uptake could be large.
Part of this could happen through making laptops act more like smartphones, too, trickling technology back up. While Sprint includes GPS technology in all its 3G networking cards and dongles--and an API for developers--that's about the extent of GPS in most mainstream products.
Netbooks already have many of the attributes of smartphones (small, fast turn-on time), and are starting to gain ubiquitous networking via built-in 3G cell cards. This makes Dell's decision to put a GPS chip in its Mini 10 quite fascinating. The company has also paired with Skyhook Wireless, which will integrate Wi-Fi and GPS data for a location result. The GPS-equipped model ships next week. Pricing is still unknown, but a reputable gadget site puts the cost at $70 above the current $300 to $350 price tag.
This turns a cheap netbook into a potentially fabulous turn-by-turn navigation system--although you certainly want to have a passenger holding it or figure out a mounting system. The Dell Wireless 700 option, as the company labels it, comes with CoPilot software as part of the cost. But it also means that people with netbooks and without smartphones will have fast and accurate location data.
Is this part of a revolution? Location-based services (LBS) have been discussed as the next big thing for targeting advertising, coupons, and, well, information of use for several years. The stars (and satellites) may finally be aligning.
Mozilla Configuration
Location preferences are a bit obscure. By default, permission-based location access is enabled in Firefox 3.5. If you click a link where a site is attempting to use the Geolocation API's JavaScript, you're presented with a prompt along the top bar of the browser, much as with pop-up windows and certain security alerts. On the left you see a message, with the site requesting location data:
On the right, a set of options, which let you set a once-only share (Share Location by itself) or a site-based share (check Remember for This Site and then Share Location). You can also click Don't Share or click the X to close the bar.
If you set site-wide location permissions, then you have to be on a page at the site in order to disable this permission. Select Page Info from the Tools menu, click the Permissions tab, and then you can modify the options for Share Location. You can use a combination of options, such as unchecking Always Ask and setting the radio button to Block or Allow. Or check Always Ask to re-enable that behavior.
To disable geolocation for the browser, type about:config in the Location bar, then type geo.enabled, and finally double click the geo.enabled preference. Repeat these steps (or double click the preference again while displayed) to turn location back on.
Although they have moved to virtualize servers, some IT managers have found there are applications, particularly specialized ones for healthcare, retailing and other industries, where vendors are wary of software support in virtualized environments.
There is only one obvious question in Cisco's overture Tuesday that it might take on Microsoft and Google in the online productivity application arena -- what took so long?
Sony introduced its Walkman portable cassette player thirty years ago this week, kicking off a revolution in the consumer electronics industry by changing the way people enjoy music.
With Microsoft's recent addition of Bing to the search landscape, the spotlight is again shining on who has the best engine for finding anything and everything on the Internet.
Cisco Systems won't try to compete with pay-as-you-go cloud computing providers such as Amazon, and instead will sell its infrastructure to those companies and provide its own software as a service.
Metageek drops down a few gigahertz with the Wi-Spy 900x: The new spectrum analyzer from Metageek, in a USB dongle form factor as with previous offerings, extracts data from the 900 MHz band, an unlicensed band used for cordless phones, baby monitors, RFID tags, ZigBee, and other mishegas. The price is $199. While WLAN use 2.4 and 5 GHz, there are still plenty of purposes for 900 MHz devices, which take advantage of the better propagation available at this frequency range.
As expected, Comcast will resell Clearwire's WiMax service: The Comcast High-Speed 2Go brand will be powered by Clearwire, starting in Portland. Comcast is focused on the mobile part, of course, since the company has its own extensive residential and business fixed broadband portfolio. Comcast has invested in Clearwire, and has previously resold Sprint Nextel service, as well.
The company will offer a Metro plan and card that works only in the WiMax footprint area, and a Nationwide plan and card that offers 3G everywhere Sprint has it, and 4G within WiMax footprints.
Comcast is using the power of the bundle, where the reduced cost in presenting and collecting multiple bills results in savings for the company and the consumer, with a 12-month introductory rate. A $50/mo bundle pairs 12 Mbps home cable broadband with WiMax service; consumers can add national 3G service for another $20/mo. The rate after 12 months is $73/mo for WiMax and $93/mo for 3G+WiMax, or $30 to $50 above the current 12 Mbps broadband rate. You pay separately for a broadband dongle, likely under $100, but that information wasn't provided yet.
Clearwire charges $50/mo for unlimited consumer roaming, and has a variety of business plans for shared bandwidth among multiple accounts. Sprint has a combined 3G/4G plan that's $80/mo (with a 2-year contract) that includes 5 GB per month of 3G bandwidth and unlimited 4G bandwidth. Comcast appears to be following both firms' leads on that topic.
With either plan, it looks like a fairly enormous discount, especially during the introductory year, but also thereafter.
I complained the other day that camera manufacturers weren't integrating support for Eye-Fi's Wi-Fi SD cards: But that's not quite right: a few camera makers have the religion. Eye-Fi is the only generic solution to moving images (and now video) from a camera to a computer or photo-sharing service via Wi-Fi. The market seems to me huge, and Eye-Fi continues to expand models, features, and distribution channels, as well as upload partners. This makes me think the market is robust, too.
However, no competing product has entered the field. Eye-Fi is a startup, and you might expect another firm--a memory-card maker, certainly--would add up the potential and try to compete. It has not happened after nearly 2 years of product in the market.
Camera makers should thus wake up: if they can't properly integrate Wi-Fi into the firmware and hardware of their cameras--and I'd argue no Wi-Fi equipped camera below the expensive professional level has yet done so--then the only reasonable partner is Eye-Fi.
Eye-Fi has two limitations in operating as a separately functioning computer-on-a-card independent of the camera's gear. First, a camera's standard power-down operation will remove the power to the card before all uploads have completed in many cases. I upgraded my Wi-Fi network by moving to 802.11n, and that reduced congestion and seems to make the Eye-Fi cards I use--which have 802.11g built in--more efficient at uploading.
Second, the camera can't alert the user that the uploads have completed. Eye-Fi gets around this with notification services via email or SMS that you can set up for each card. But a ding or dialog would go a lot further.
Eye-Fi has a page at its site that I was unaware of that lists all the camera models that have Eye-Fi integration. This includes 5 recent Casio models that signal whether an Eye-Fi is inserted, allow Wi-Fi to be turned on or off, that stay powered up until uploads are completed, and which indicate transfers in process.
I expect it's a multi-year process for Eye-Fi to convince cameramakers that the company will be around in the long term, that it is sui generis for Wi-Fi digital cards, and that firmware integration enhances the value of a new camera (i.e., more sales from people who thus need the new cameras) instead of pushing money over to Eye-Fi that the makers would rather keep themselves.

SlashGear has gotten their hands on the new Novatel MiFi 2352. What makes this different from the previous version offered by Verizon and Sprint? Well, this one is GSM based and could see 3G download speeds of up to 7.2 Mbits and upload speeds of nearly 5.76 Mbits.
For a detailed review, including unboxing pictures of this personal WiFi hotspot check out the review below.
Sure, Clearwire has Baltimore and Portland, but Atlanta eclipses those: The Clear network in Atlanta spans 1,200 sq mi and passes 3m people. Given the hideous commute and highway backups, I can see a ubiquitous network that's cheaper than and faster than 3G competitors being a windshield warrior and mobile work team must-have. Clearwire maintains that 4 to 6 Mbps downstream is typical, with an over 15 Mbps burst rate.
Clearwire pairs the Atlanta announcement with a laundry list of gear customers can use to connect, which has increased considerably in the last few months.
Wireless networks are always a chicken-and-egg problem. Wi-Fi insinuated itself into nearly every mobile device because there was no network lock in. You could install one hot spot and have one adapter and have all the freedom you needed to cut the cord. Wi-Fi became cheap to include in mobile devices years ago, and required no carrier or regulator relationship.
Cellular 3G and 4G networks have a harder row to hoe because every adapter will have both high cost and provider lock in. 3G cell modems are starting to become a standard feature on some netbooks and laptops, although it's a financial risk to the makers of these computers, as the underlying cost of mobile broadband modems remains high. If the user never activates the modem, or cancels within a short period, the buyer isn't bearing the full cost of that adapter based on the current model. (It's not clear whether carriers and/or modem makers absorb some of this risk to ship more adapters and gain more customers, too.)
For Clearwire, it's a bit different, because Motorola and Samsung are both major investors and principle equipment manufacturers. This can be awkward, because the two makers can't offer gear to Clearwire at cost, but neither do they have a motivation to extract every last dollar.
Clearwire notes in this release how many WiMax adapter are now available, and in what variety. For laptops, there's a $60 (or $5/mo) USB modem. This takes care of legacy laptops and even desktop computers. USB modems for 3G networks have multiplied and added features (such as having a microSD slot) because the ability to move the modem among multiple computers is desirable.
For home users, there's the Clear Residential Modem, which is $80 or $5/mo; voice calling requires an additional $15 adapter and a $25/mo calling plan (competitive with Vonage, and from half to one-third less than Comcast's).
Apparently, this is the soft launch of Clearwire's Clear Spot, a Wi-Fi/WiMax gateway ($140), which is battery powered and requires a Clear USB modem. As I previously noted ("Clearwire Offers CradlePoint WiMax/Wi-Fi Hotspot," 31-March-2009), this is a Clearwire-enabled version of a product that CradlePoint has offered for some time. On the laptop side, Clearwire lists a variety of Dell, Fujitsu, Lenovo, Samsung, and Toshiba notebooks and netbooks. A Panasonic Toughbook is coming later this year.
An anticipated 3G/4G broadband modem is due "this summer," which will combine Sprint 3G with Clearwire WiMax, and start allowing business customers in Clear coverage areas to upgrade to have the benefit of a faster network at home and roaming while away, or in weak WiMax coverage areas.
MetaGeek breaks the $100 barrier with the Wi-Spy 2.4i: The company's new USB spectrum analyzer is a revision of its entry-level model, which handles 2.4 GHz (2.400 to 2.492 GHz). A spectrum analyzer constantly samples the radio frequency environment around you; software that works with the analyzer can derive graphs, charts, and other visual and numerical representations. You use a spectrum analyzer to troubleshoot problems in wireless network, identifying interferers, or to plan networks by figuring out what's already in place and testing access points' reach when you fire them up.
While Ubiquiti sells 2.4 GHz spectrum analyzers that are less expensive (the cheapest can be found for $40), I believe that MetaGeek is offering higher resolution (375 KHz instead of what looks like about 512 KHz). MetaGeek also has software support under both Mac OS X and Windows (with the free Chanelizer Lite).
MetaGeek also dropped the price of its next-level-up analyzer, the Wi-Spy 2.4x, which has an external antenna, and both finer and adjustable resolution. It's now just $199. The 2.4/5 GHz Wi-Spy DBx took a $200 plunge, too, and weighs in at $599.
Also, in this Newsday piece and elsewhere, Sen. Schumer seems to think that there are similar and inexpensive systems running all over the U.S. There are now a number of production systems in the U.S. (and elsewhere) on trains, but there isn't anything running on the scale of LIRR. The closest is the MTBA (Massachusetts Bay Transportation Authority), which is either in the process of or finished with a rollout across 13 commuter lines after a successful test on a Worcester line.
Other rail-Fi projects are much smaller in scale, often involving (as in Utah and elsewhere) new projects that were designed from the start to have Internet service in stations and on board.
In the Bay Area, the BART system has a contractor in place (Wi-Fi Rail) which is ostensibly in the process of setting up systemwide Internet access as we speak. If Wi0Fi Rail is successful as it rolls out in the Bay Area, it's likely that the company's approach will be useful in other metro areas that are otherwise quite expensive to get backhaul and signals through.
In talking early this year with Aircell's CEO, the firm planned to create a partnership with the winning bidder. "Anybody who gets that license is doing so on the basis of forming a relationship with us where they operate the physical network in Canada," Jack Blumenstein said back in February. Blumenstein said that the rollout in Canada would likely be in 2010. He also noted that only 20 base stations would be required to serve all of content, because Aircell already had a number of near-border locations that could be turned north.
The bid price seems rather high, but that's clearly in expectation of the winner being part of a cross-border monopoly on this particular service by dint of owning the license. While Canada has a smaller population, there are plenty of aircraft crossing the country and traveling back and forth to the U.S.
Eye-Fi has added a fifth member to its product matrix, the Pro which supports RAW format uploads, direct computer transfer: Eye-Fi's list of options is getting a little longer than makes sense for a simple product, but the distinction between Pro and the others is clear. If you need to upload anything but JPEGs, you need the Pro card (street $150, 4 GB, SDHD). Maybe professionals and plenty of amateur photographers prefer the loosely-defined RAW format (not a standard) in which the quirks of the image sensors aren't smoothed out. This allows better post-capture correction.
An additional feature found only in Pro is allowing transfers using the Wi-Fi ad hoc mode. All Wi-Fi base stations and some software found in operating systems or added on use infrastructure mode, which hub and spoke. Each station (a spoke) communicates via a coordinating access point (the hub). In ad hoc mode, however, all devices are equal players and there's no central coordinating point. (Ad hoc mode is also responsible for the ubiquitous Free WiFi networks you see at airports, because if you're not connected to a network and ever used an ad hoc network, you broadcast the ad hoc names under Windows XP and some other OS's.)
Ad hoc mode is useful for photographers, because it means they can transfer images directly to a laptop or computer they have with them without having to also have a gateway. Mac OS X offers both a software base station mode and ad hoc networking, but Windows only has ad hoc built in for direct transfers. One year of hotspot access is included at Wayport operated locations. (Eye-Fi says 10,000 hotspots, but given Wayport has merged into AT&T, does that mean that the 7,000 Starbucks and thousands of others are excluded?)
Eye-Fi also updated all its models to support Selective Transfer. With this new mode, any image marked as protected or locked (depending on camera firmware options) will be uploaded, while all other images will not. That's a clever way around the fact that only one high-end digital camera so far talks directly to the Eye-Fi card. I was really expecting at least one camera maker to integrate Eye-Fi as an offering, using the firmware as a way to enable more features. Ah, well; camera makers aren't known for understanding what users want out of image transferring over Wi-Fi.
Selective Transfer is available through a firmware update via the Eye-Fi Manager. Connect your Eye-Fi card via a USB card reader and run the update to get the new feature.
Eye-Fi has defined its featureset as seven items, all of which are part of Pro: JPEG uploads, online sharing, video uploads, geotagging, hotspot access, ad hoc transfers, and RAW uploads. As you move down through the matrix, fewer features are found, but the cards cost less, too. Cards start at $50 for transfers only to a networked computer (not via ad hoc) with the 2 GB Home model. You can upgrade cards that lack webshare, hotspot access, and geotagging for $10, $15, and $15 per year, respectively.

Qualcomm says it has 600 Mbps 802.11n 4x4 solution: The cellular and GPS chipmaking giant finally releases new Wi-Fi gear, blowing the roof off with a 600 Mpbs (raw), 4-radio, dual-band, 4x4 antenna array--the N-Stream Wireless LAN WCN1320. The chip will sample this month, allowing manufacturing partners to start designing products around it. A production date isn't announced.
Ever since the grand compromise was made that allowed Task Group N in the IEEE 802.11 Working Group to move forward, the option of having four radios and a 4x4 antenna array for a raw data rate of about 600 Mbps has existed. However, the cost of such a device would be so high that until 2-radio (raw 300 Mbps) 802.11n was in wide use--especially in enterprises--the 4-radio flavor didn't seem to be something the market would demand and pay a huge premium for.
1 1/2 to 2 1/2 years into the N revolution, depending on how you count, the time must be ripe. Qualcomm is advertising this product as a way to carry multiple HD streams across a house. The chip integrates an application processor, which allows a set-top box or other equipment maker to offload some processing to the chip instead of adding an additional burden.
Qualcomm acquired the pioneering MIMO Wi-Fi firm Airgo a couple of years ago, and this is the first standalone Wi-Fi product that's emerged from the firm since then.
The company isn't the first to announce a 4-radio 802.11n solution. The startup firm Quantenna announced a 4-radio, 4x4 antenna chip that it could configure in a pair for what they say would be an aggregate of 1 Gbps across 2.4 and 5 GHz. As far as I can tell, Quantenna is sampling, but no products are yet shipping.
The Wi-Fi positioning firm Skyhook Wireless gets a nice snapshot in the New York Times: I've been following and talking to Skyhook for many years, and the Times nailed the salient points quite well in a non-technical and useful way. The interesting figure is that Skyhook says it handles 250m requests per day for positioning data. There's a terrific video embedded in the article that shows a heatmap of location requests in Manhattan over a 24-hour period.
Most of the requests come from iPhones, Skyhook says. Apple has sold approaching 20m iPhones worldwide, and that means it's likely that the average iPhone users is pushing out several requests a day. I know I do! The iPod touch can also tap into Skyhook's system, but because the touch lacks a second channel to request information it must be connected to a Wi-Fi network in order to retrieve positioning data.
Metro-scale Wi-Fi gear maker purchased by firm focused on smart-grid technology: Trilliant claims that SkyPilot's backhaul tech--an awfully clever solution to frequency reuse-is perfect for handling metering and other data collection. Trilliant might be right. SkyPilot's backhaul/distribution tech involves using sectorized antennas operated in a scheduled manner to avoid interference. This bought them some of the best aspects of time division and power limit rules.
The FCC had granted a ruling years ago to Vivato that allowed extremely high signal output (the maximum legal limit) in quasi point-to-point scenarios; previously, the limits were much lower unless you had a very specific P2P setup. SkyPilot used that exception to push out tens of watts of power in 5 GHz, allowing extremely long-distance links from a single backhaul device. By rotating among several antennas, one device could serve 8 feeders on a scheduled, GPS-time linked basis.
Trilliant's business is in smart meters, and earth2tech reports that the company has worked with a variety of backhaul options and firms. But with the federal government plowing billions into electrical grid and utility development, everyone with some action in smart grids and meters now needs a network technology. Metro-scale Wi-Fi equipment maker Tropos has gone into that space, although it also seems to have a significant public-safety wireless business, too. Smart-metering firm SmartSynch is an early AT&T partner for cellular backhaul under a new arrangement that makes mobile broadband sensibly priced for metering.
Of the other early companies that were making mesh or metro Wi-Fi gear, only BelAir is still pumping out real news. BelAir is the equipment provider for Cablevision and USI Wireless in Minneapolis, which are both reasonably big networks. BelAir may have some other cable firms up its sleeve, too; Comcast may decide to roll out subscriber-only Wi-Fi, too. Strix Systems is active, but it hasn't had any big contract wins for some time.
In the early days, Tropos was aligned with EarthLink, SkyPilot with MetroFi, and Strix with Kite Networks for municipal Wi-Fi rollouts. BelAir had no specific alignment, although it was tapped by Toronto and other networks more on a case-by-case basis. EarthLink exited muni-Fi, MetroFi shut down, and Kite went out in a blaze of confusion.
There's a lot of geekiness in this press release. The company provided some updates on its 7.2 Mbps upgrade plan. The HSPA (high speed packet access) technology it uses, part of the GSM roadmap, is currently limited to 3.6 Mbps. The 7.2 Mbps flavor isn't in wide use worldwide, but it's starting to kick in as demand from smartphones and mobile broadband users with netbooks and laptops steps up.
The timing is clear: Apple is about to release a revised iPhone, one that various usually reliable sites report will record video, take larger pictures, and have a faster processor. It will also almost certainly contain a 7.2 Mbps HSPA chipset, and thus be a huge and immediate drain on 3G resources across AT&T's territory. (Apple's developers conference is in two weeks, at which time the company will likely announced that the iPhone 3G+ and its iPhone 3.0 software will be released in July.)
AT&T's CEO said at the All Things D conference run by the Wall Street Journal this morning, in reference to Wi-Fi that there's a growing "bandwidth requirement," and that mobile broadband has to meet what fixed-line (fiber/DSL/cable) services can provide. Wi-Fi is a "bridge," he said, and AT&T can back its 20,000+ Wi-Fi hotspots with fixed-line services. But obviously the company also has to beef up mobile broadband, too. (The 20,000 count is new; it was about 17,000 not too long ago.)
In order to support the 7.2 Mbps HSPA service and future LTE, AT&T says it's doubling the amount of bandwidth devoted to 3G in many metropolitan markets, and bringing more backhaul to "thousands of cell sites." The company couches its backhaul statement by saying "fiber-optic connectivity and additional capacity," meaning it's not bringing fiber to thousands of cell sites, but to some of them.
The company will also add 2,100 cell sites to improve density. The greater the density, the smaller the cells, and thus the fewer devices that connect to each cell, increasing frequency reuse over a given area.
AT&T is also expanding its use of 850 MHz, which has better penetration to interior spaces, and can cover more area from a single base station. That's a smart move to counter some of the CDMA advantage in the U.S., where Sprint and Verizon seemingly have better network coverage. (AT&T's network was built up as more of a patchwork in many ways, and AT&T still lacks its own coverage in some small but significant parts of the country.)
On the Wi-Fi side, AT&T says it will offer seamless Wi-Fi/3G switching on "many" smartphones. That might be a reference to a capability that could be part of the iPhone 3.0 software due out perhaps as soon as July. AT&T currently has a very silly SMS-based notification system to get a code that allows free access, although Devicescape's Easy Wi-Fi for AT&T (99¢) automates the process. (It's a mystery that AT&T didn't either license and distribute that software from Devicescape or develop its own similar approach.)
A bit buried at the end of the paragraph is rather fascinating: "AT&T also can create permanent or temporary extended Wi-Fi zones in areas with high 3G network use, like a grouping of hotels or a festival." Fascinating. This is an interesting admission of scarcity coupled with AT&T's fixed prices for smartphone 3G use (as opposed to 5GB/mo limits on laptop 3G connections).
Wi-Fi's key advantage and problem is its low power, which both allows and requires a honeycomb of tiny radius cells. In a dense area with lots of usage, AT&T could push in dozens of Wi-Fi access points tied into a fiber network and overlay gigabits per second of additional capacity without stressing the 3G infrastructure. I've never heard of a carrier suggesting that they might do this before, however.
AT&T also said in this release that it's working towards releasings its 3G MicroCell, a femtocell product that's been talked about widely and is in some test customers' hands. It's still not clear whether AT&T will follow the Sprint model of adding a fee for unlimited monthly incoming calls and U.S. outgoing calls, or the Verizon model of paying a large fee for the femtocell, and gaining only indoor coverage improvement. AT&T is unique at this point is having a 3G femtocell for voice and data; Verizon and Sprint's system's are 2G and voice only.
Verizon has joined the bandwagon and announced a new open access plan for its network. This plan will go into effect next year and means any application can run on any device from any manufacturer and will have full access to the Verizon spectrum.
Verizon representatives say this move was prompted by two different motives, the first being more sophisticated customer needs and the second is an explosion in innovation. They are hoping to see an wave of wireless devices flood the market in more arenas than the traditional handset market.
Some speculate that this decision is tied to the upcoming 700MHz spectrum auction, Verizon denies this was their motivation but the timing couldn’t be more coincidental.

The much anticipated 700MHz spectrum auction in January officially has another bidder. Google has announced that it will toss its hat in the ring.
A Google representative says that the company’s goal is to offer American consumers more choices in an open and competitive wireless world. Officially, Google doesn’t have to announce its plans until December 3rd so until then speculations abound.
Some say Google has no interest in becoming a network provider, others look to the previously proposed four open access provisions, or possibly they will lease space to others. Nothing is certain at this point except that when Google does make its plans known it will create a nationwide buzz.

CBS has just made an announcement that is sure to delight New Yorkers. From Times Square to Central Park and from 6th to 8th Avenue will become the new CBS Mobile Zone. This zone will carry free Wi-Fi for cell phones, laptops and other devices that want to access the internet or even make voice over internet phone calls.
In return, CBS gets ad impressions, tons of them. Visitors to the region will be greeted with a sponsored homepage with hyperlocal news and information for people within the specified area.
CBS Outdoor Chairman and CEO, Wally Kelly, explains that this is just one example of how CBS is dedicated to turning Outdoor assets into next-generation interactive platforms.

The deal struck between Sprint Nextel and Clearwire back in July has been scrubbed and the national WiMAX network took a hit. Both companies say they will continue to work on the technology independently.
Although both companies appear committed to developing WiMAX, their shareholders may actually hold the reins as huge sums of money are necessary to go forward.
Manufacturers of WiMAX equipment feel the technology is still sound and they plan to go ahead with device creation, it just may take longer for the technology to take hold. AAA So, the future of WiMAX is uncertain, it may be better suited for emerging markets than the U.S., only time will tell.

The recent departure of Sprint CEO, Gary Forsee, is having some far reaching impact. The WiMAX build out between Sprint Nextel and Clearwire is the latest victim as the proposed joint, nationwide WiMAX effort has been dropped.
Sprint’s corporate shake up was not the only reason the proposed venture was nixed,the complexities of the transaction were also cited as a stumbling block. So that leaves the American WiMAX project in a bit of a conundrum, do Sprint and Clearwire go out and forge independent networks or will new bonds form?
In the meantime, WiMAX is progressing nicely overseas, proving that they technology is valid and workable.

IBM has joined forces with MediaTek to develop microprocessor chipsets that will wirelessly transmit videos almost instantly.
These chipsets will let you connect HDTVs with set top boxes without the need for wires. They will also transfer data at rates of at least 100 times that of current WiFi standards.
This new technology, mmWave wireless, is expected to be used widely in homes and offices.

WiMAX has a reason to celebrate. The International Telecommunications Union has just approved the non-cellular technology as part of a 3G standard. This means that operators with 3G spectrum in their 2.5 GHz bands globally can use WiMAX to build out a spectrum.
The last interface added was back in 1999 when ITU added IMT-2000 as it established the original technologies. IMT-2000 and five other cellular standards had to be used in the 3G standard, now the door is open to WiMAX.
But all is not rosey for WiMAX, the debate between technologies is far from over.

The BBC has announced that the Health Protection Agency is going to begin a systematic research program on how WiFi is used. The goal of this study is to determine how WiFi is being used and the possible radiation exposure that results from such use.
Spokesmen from the HPA believe that the study will confirm the safety of using WiFi, but feel that since England’s Chief Medical Officer suggested children limit their non-essential cell phone use due to potential exposure to radiation that a study into the radition emmissions of WiFi was the next logical step.
Results of the study will be publicly available, but officials reinforce their belief that WiFi is safe.

Chicago’s WiMAX World show displayed a large rift between Mobile WiMAX supporters and municipal WiFi.
With continued problems halting all progress in the municipal WiFi world, WiMAX supports say they have the solutions. They contend that their licensed spectrum will guarantee continuous coverage and that indoor reception will not be as problematic as it is for WiFi.
But all is not rosy in the world of WiMAX, hardware is a huge problem. Every laptop has built-in support for 802.11b/g and will soon have 802.11n, this won’t be the case for WiMAX for quite some time, several years at least.
Right now all eyes are on Sprint and their pricing of Xohm. A reasonable price point may make or break a WiMAX solution for the masses.
