Now that Nextel has gone and dashed Flarion's hopes for a nationwide deployment, there are signs that T-Mobile USA's parent might be seriously considering using Flarion for a 450 MHz deployment in Germany. Unstrung has the details here. So don't count out Flarion just yet.
Siemens is already onboard to produce equipment and T-Mobile has a stake in Flarion so it's hard to see how this deployment won't happen. But after the Nextel/Sprint deal, anything is possible.
The 450 MHz band in Europe has to be driving the major cellular vendors crazy. Just when they thought they had their carrier customers locked into a nice GPRS/UMTS/HSDPA upgrade path, another swath of spectrum opens up allowing another technology (a potentially better technology) to take hold.
If there is one certainty in the years ahead it is that there is no certainty about which cellular technology will dominate. Every new band of spectrum that opens up promises new opportunities and new threats. This is great news for consumers (and industry analysts) but not the best news for the large vendors who must keep a hand in every new wireless technology and standard.

Daily Wireless reports on the forthcoming Samsung SCH-i730 PDA phone, which will include EV-DO, Wi-Fi and Bluetooth. This is the perfect mix of WLAN and WAN connectivity. Now will Verizon Wireless drag its heels on supporting this device or will Sprint be first out of the gate? Either way, I believe that carriers, despite their fretting about lost minutes of use, will learn to love Wi-Fi, for it will give their EV-DO networks some much-needed breathing room.
This could be my next handset.

Dave Mock is a wireless consultant and analyst with currentofferings.com and author of the forthcoming book The Qualcomm Equation. Dave took a moment to answer a few of my burning telecoms questions...
Q: What are your thoughts about a Nextel/Sprint merger? Is this good news for US telecoms industry? Good news for consumers?
A: The Sprint/Nextel combo will have pros and cons but overall I think its a move in the right direction for both the industry and consumers. Nextels strained network will get relief and Sprint will get some very profitable channels. The different network platforms will slow the integration though theyll operate two networks for a while.
Q: What are your predictions about Qualcomm and China? China has been testing the two leading 3G technologies along with a homegrown technology. Any thoughts on how it will all play out?
A: I think China will push TD-SCDMA into the market somehow, with the principle purpose of leveraging a bigger role in the industry. Whether it is successful or not probably doesnt matter as much as what it buys them. I think arguments of Qualcomms assertion of IPR in the standard are moot, as I dont see it as a significant driver of royalty for them. However it plays out, CDMA and WCDMA should still develop a significant presence.
Q: EV-DO vs. HSDPA: Which do you like better, and why?
A: I like EV-DO because its here today. Ultimately, HSDPA promises more flexibility for operators, but its got some distance to go before widespread deployment.
Q: Qualcomm is becoming a network operator with its MediaFLO deployment. Why is Qualcomm doing this and do you think it will pay off?
A: Well, Qualcomm has no interest in being a network operator. But they certainly would like to see the spin-off take fire to boost demand for wireless broadband (re: their EV-DO). Its a typical practice for them I call seeding the market, and its very forward thinking as there is not yet significant demand for streamed media. Odds are it wont pan out well (just as several other ideas have flopped), but they only have to be right once to hit it big again.
Q: Since MediaFLO will using an ODFM technology, is this a sign that OFDM is going to drive Qualcomm's next-generation chipsets?
A: I think OFDM will play a bigger role in Qualcomms designs going forward (where its appropriate). When it comes to chipsets, Qualcomm has demonstrated competency in integrating whatever customers demand be it GSM, WCDMA, OFDM or maybe even Wi-Fi. As long as OFDM offers performance advantages, theyll play.
Q: Speaking of Wi-Fi, do you think that Wi-Fi-enabled handsets will hurt the success of EV-DO and other 3G technologies, or increase usage of these networks (or both)?
A: I think Wi-Fi is shaping up to be a serious threat, and this is no surprise to anyone in Qualcomm. But I think it hurts Qualcomm less than the operators, who will lose control of the channel. Regional (and municipal) Wi-Fi deployments have the biggest chance of limiting the uptake of EV-DO, and pressuring service prices. Actually, Wi-Fi itself is not the true threat its the aggregation of hotspots and roaming agreements for WLANs that potentially could cut out EV-DO. But so far these efforts have failed.
Q: Should Qualcomm be frightened by WiMAX? And do you think the vendor will ultimately support WiMAX?
A: Qualcomm should be concerned about WiMAX and anything like it and they are. The standard itself will likely be stalled to no end as it is too broad right now, but some significant decisions will be made in 2005 that could put it on the fast track or send it out to be shot. Intels weight shouldnt be underestimated here, and I think theyll be successful in getting many in the industry to adopt the standard if it comes through in marketable form.

Glenn makes sense of this "Wi-Fi in the air" story.
The FCC didn't just suddenly decide to allow Wi-Fi on planes. Two years ago, the FCC lobbied the ITU to allocate global satellite spectrum specifically for the purpose of providing in-flight broadband. This is not news. The news now is that the FCC will be allowing a different form of backhaul (ground to air) to the planes.
The real reason we haven't see Wi-Fi on domestic flights yet is lack of resources and vision. Domestic airlines are terrified of any new cost, regardless of whether or not they may actually profit from it. They'll come to their senses after one of the more aggressive carriers (Jet Blue?) starts deploying Wi-Fi. I also look forward to seeing data from Lufthansa that shows they are nabbing customers from competing carriers based solely on their Wi-Fi service.
And there are other, equally compelling, reasons why I believe airlines will ultimately adopt wireless broadband backhaul to their jets: telemedicine, real-time aircraft monitoring, VoIP, security, content. Like any other commercial venue, wirleess broadband in general and Wi-Fi in particular will serve many audiences and many needs.
What I want to see discussed is the use of VoIP over Wi-Fi on aircraft.
VoIP is currently allowed on at least some of the aircraft using Connexion by Boeing and yet we have the FCC taking a year to study cellular phone use on aircraft. What happens when your cellular phone has Wi-Fi embedded in it? Will a flight attendant tell you not to use your phone even if you're only using Wi-Fi?

According to The Economist a company out of Atlanta, Georgia plans to launch an "airship satellite" stationed 13 miles off the ground to function as a cost-effective low-orbit satellite.

This "stratellite" certainly appears to be less expensive than the real low-orbit satellite WildBlue which is coming on line in 2005.
The airship could be used to light up cities with DSL-like bandwidth. At 13 miles, I suspect latency will be an issue. But it certainly is a convenient way of manufacturing the tallest tower in town and would make a nice platform for fixed wireless base stations. Perhaps TowerStream would be interested in such a service.
Thanks Chris for the heads up.

Firetide has posted a case study on its first hotel Wi-Fi mesh deployment at a Holiday Inn in Bluefield, West Virginia (not exactly a high-profile property, but you gotta start somewhere).
I've been following Wi-Fi in hotels for a few years now and was surprised that mesh didn't find its way into these properties sooner. Anything that makes for a faster installation is going to attract the attention of general managers and integrators alike. I'm glad to see a real-world deployment.
According to the case study, the hotel used mesh routers and access points to cover the entire property (134 guest rooms, two conference rooms, the office and the pool are) in just two days. I estimate that a conventional Wi-Fi installation of this size would have taken five to seven days.
The hotel uses a DSL connection for backhaul, keeping operational costs low; a number of small hotel properties use DSL for their main connection rather than a T1 line. They'll have to upgrade as usage increases, but there's no sense is paying for what you don't yet need.

Well, it looks like we've got a merger happening between Nextel and Sprint. I find it disappointing. Despite what they will say in the weeks and months ahead, this merger isn't about improving the customer experience; it's about Nextel sidestepping a very expensive network deployment -- one that could have been more sophisticated than anythng the other carriers had in store.
Instead, Nextel will likely follow Sprint's lead on the EV-DO network. It's a great technology, but Verizon's got the exact same technology plus a head start.
Nextel's Research Triangle deployment using Flarion's gear has been by most accounts a success and the pricing was very aggressive at $35/month. I would like to see a major carrier commit to some seriously high-speed broadband wireless, regardless of what gear they use: Flash-OFDM, WiMAX, whatever. Maybe it will be AT&T (who just partnered with Intel).
Here's an interesting analysis of the situation thus far.

Vonage has partnered with Viseon to promote a videophone package and service in Q1 2005. The phone is going to look a bit like this:

I think videophones and VoIP make a powerful combo and will popularize yet another acronym: VVoIP. The Apple iSight inserted new life into the videophone market a year ago, but carriers have been largely unenthused by the devices. I do think people will want this product/service - particularly travelers who want to stay in touch with loved ones (and possibly the office).
But I think a few things need to happen before this can become mass market:
1. A video phone/video softphone bundle. This would include the fixed line phone and a webcam that attaches to the laptop (like the iSight) and includes supporting software. I don't think it will be enough to just sell the fixed line phone by itself. Vonage needs to provide a package suited to business travelers so they can stay in touch with home. They key is to provide bundled devices so that people instantly have someone to "video" with. I think Apple would have had much greater success with iSight if they had created a non-Apple video phone to bundle with it. But they're only just beginning to test the non-Apple waters with the Windows iTunes software. Perhaps their much-rumored Apple wireless phone will be another step in that direction.
2. Video Phone Interoperability. I want to know that this phone will work with other webcams that are already out there. Is there a videophone standard in the works already? I'd certainly like to see some standard -- officially or unofficially -- that everyone can support, including Apple. Apple's iChat software does interop with AOL software, so that's a start.
3. Cellular Phone Interoperability This is perhaps of less importance, but I'd like to see a point where VVoIP works with cellular-based video. This is no doubt a larger challenge because carriers don't like to open their "walled gardens." But I think it's an issue that will need to be addressed eventually. Perhaps Wi-Fi-enabled smart phone/camera phones will bypass carrier networks altogether.
Anyway, I'm glad to see Vonage out there looking for more ways to utilize its network. I'd like to see it pursue home monitoring services as well, as I believe this is currently being overlooked by all carriers.

Intel has released a few results of a survey of more than 2,000 men and women and their attitudes toward technology. The survey finds that women are more predisposed to wanting wireless-enabled laptops than men. According to the release:
Not often recognized as early adopters, women in the survey are revealed as leading the way with wireless Internet access, as more women than men believe this is one of the most important features for a laptop to have (39 percent women versus 29 percent men). While men (51 percent) and women (48 percent) agree that the airport tops the list of the most useful locations to have wireless Internet access, women (38 percent) are more likely than men (30 percent) to desire a connection in a doctor's office as well.
Wi-Fi isn't mentioned specifically, but I think that's what we're talking about here.
In a recent investor's briefing, Intel says that its Centrino (Wi-Fi) line has generated $5 billion in revenues in just two years. Not too shabby. Now Intel is aiming for the desktop. People may wonder why Wi-Fi would be useful in a desktop since it is a stationary device. For starters, wiring is a pain and always will be. But I think the larger opportunity is home monitoring and control. So many devices are going to be running on the home Wi-Fi grid that it will make sense to have all computers supporting Wi-Fi.
Finally, given such user demand for wireless devices, I wonder if Intel and Qualcomm will learn to play nice and start cranking out a line of Centrino/EV-DO devices. And why not add a Centrino/HSDPA line as well.
Yes, I know WiMAX is coming. But Intel should hedge its bets. It owns the wireless laptop market and should do all it can to keep that lead.

Siemens Loves OFDM
Siemens is getting some blazing speeds out of OFDM. It is also going to be building OFDM gear in partnership with Flarion. OFDM is becoming the technology of choice for next-generation networks. Qualcomm's on board. Wi-Fi uses it. Who's next?

For several years now, the US has taken a back seat to Asia and Europe in regard to next-generation wireless deployment. A mix of competing wireless standards and tepid SMS usage were largely viewed as a sign that the US could not keep pace with the rest of the world.
Not any more.
While Japan and Korea will retain their lead for some time, the US is poised to surpass Europe in network speeds, bandwidth consumption and, more important, network variety. Here's the landscape as it looks today:
Next-gen Network Plans
Cingular: UMTS/HSDPA (6 cities live with UMTS)
T-Mobile: Wi-Fi currently and UMTS/HSDPA appears likely
Verizon Wireless: EV-DO (14 cities live)
Sprint: EV-DO
Nextel: EV-DO Rev A or Flash-OFDM
Europe will see isolated HSDPA deployments, but nothing on the scale that we're going to see here. That's because Verizon's EV-DO network is pushing the other carriers to keep pace or try to leap ahead. And because Europe is on one standard and one set of train tracks, things are going to move a bit more slowly. One big wild card is the extent to which Flash-OFDM and UMTS-TDD succeed in Europe.
Remember when the US was criticized by Europe for its chaotic mix of wireless technologies? Ironically, this chaos appears to be doing more good than harm as it creates a more dynamic technology horse race.
And then there is bandwidth consumption. So what if US text messaging isn't on par with Europe; Americans are now paying for TV feeds from Sprint and are hungry for more frames per second. Qualcomm is priming the multimedia content market with its own nationwide OFDM rollout. And then there is Wi-Fi, which is wildly popular in the US and is driving carriers to create "Wi-Fi-like" wireless experiences.
Finally, there is Nextel, which will deploy a technology that is in line with what's going on right now in Korea. Truly cutting edge. (I'll post my thoughts on which vendor will win out in a few days.)
Yes folks, things are looking up for wireless consumers in the US.

Another mesh hardware vendor is taking a shot at the emerging outdoor market. Strix announced its new equipment today, joining the likes of Tropos Networks and Belair Networks. Strix differentiates itsself by allocating radios to specific functions and supporting standards throughout.
Given the growing number of municipalities pursuing outdoor networks, this looks like a good move on their part.

MuniWireless has culled together eight RFPs from municipalities around the US, all looking to deploy wireless networks. Most of these networks will use Wi-Fi and most munis hope to the charge for the networks. Rome Georgia is planning an 802.16 network for its own use. All in all, there's a nice mix of large and small, public and private.
You can download it here. Esme Vos has done an excellent job of making MuniWireless a valuable resource for tracking what has turned out to be quite a revolution.

Scott Carson is no longer president of Connexion by Boeing. He's moving over to VP of commercial airline sales and in his place is Laurette Koellner, who was formerly VP of Internal Services. Hard to tell if this means major changes are in store for Connexion. I like Scott and suspect his skills are needed to help boost sagging jet sales. I still don't fully understand why the new Dreamliner jets don't ship with Wi-Fi by default; maybe he can change that. It seems like a Wi-Fi/picocell infrastructure should be included so that Boeing is in a position to sell the value-add services that airlines increasingly need: consumer voice, data, entertainment, real-time aircraft maintenance, telemedicine, etc.

Bad News for Navini; Good News for IPWireless
Unstrung reports that PCCW has dropped Navini in favor of IPWireless. Navini had tried to go the proprietary fixed wireless route awhile back, then began backing 802.20 only to change course and join the WiMAX Forum.

Take water, add wireless technology and what do you get? Some pretty nifty applications. Applications that conserve water and alert you to water leaks at home.
The Motorola home monitoring system includes a device that will send you an email if it detects a water leak. Anyone who worries about freezing pipes in the winter may find this device handy.

And Wellspring Wireless announced that is will be using ZigBee to develop wireless monitoring devices for multi-tenant buildings.

These devices allow landlords to monitor usage by unit. Landlords will love these devices because they can install them under the guise of "water conservation" while giving them the opportunity to bill tenants as water usage increases over a set limit. The ends do justify the means, particularly out here in Southern California.

Wi-Fi Article
Yours truly is quoted in an article by Jeannette Borzo on some of the creative uses for Wi-Fi networks once they're in place. Wi-Fi isn't just about Internet access anymore. In fact, I was at the Electronic Home Expo recently and was suprised to see just how many home monitoring devices and remote controls that now use Wi-Fi.

The IEEE has a new working group up and running (802.22) and they've got a new acronym that is sure to confuse media and profit analysts for years to come: WRAN, which stands for wireless regional area network.
WRAN joins a growing list of acronyms defined by coverage area:
- WPAN (personal area network)
- WLAN (local area network)
- WMAN (metro area network)
- WRAN (regional area network)
(There is also 802.20 "wireless mobility" which is in desperate need of a good acronym.)
Labeling a technology by coverage area is an inperfect solution. WLAN can easily be powered up to cover several miles and WMAN is not likely to see many deployments over 5 to 10 miles (let alone 30), at least in the unlicensed band.
WRAN will attempt to bring order to new unlicensed UHF/VHF bands that will open up as part of the FCC-mandated digital television "upgrade." Specifically, the working group's charter is to "develop a standard for a cognitive radio-based PHY/MAC/air_interface for use by license-exempt devices on a non-interfering basis in spectrum that is allocated to the TV Broadcast Service."
The "non-interfering basis" will probably be the technical issue most contested by broadcasters in the years to come. But every little unlicensed crack in the FCC wall is a good thing and I wish this group luck.

I want to clarify something about the CNET article that states that Nextel is "dropping" WiMAX from consideration.
WiMAX was not a serious contender to begin with. Yes, Nextel had taken a very close look at the technology, but so have all the other operators. Nextel needs to get moving quickly on a network that will allow them to compete with Verizon Wireless in 18 months, not four years from now. So, it will either use the same gear that Verizon is using or take a chance on Flarion's solution (which functions today very much like WiMAX is expected to function three years from now).
Now I realize the WiMAX backlash is in full swing, and that much of it is well deserved. But I also think we need to keep things in perpective. This news is not a setback for WiMAX any more than Cingular's decision to deploy HSDPA is a setback for WiMAX.

Engadget is reporting that Canadian cellular carrier Telus has finally launched a Fastap-enabled LG handset.
Fastap is keypad layout, developed by Digit Wireless, in which the letters are interspersed between the numbers, as shown below. The letters are also raised slightly to prevent selecting multiple keys at once.

I first met the folks from Digit Wireless three years ago and I thought the keypad was a winner back then. Apparently carriers and device manufactuers have been less enthused. But I'm glad Digit Wireless stuck with it because this really is a great way to squeeze a lot of functionality into a little space.
I've used Fastap and I believe that it's a lot easier to learn than Blackberry's latest keypad incarnation, included below.

I still prefer qwerty but I also wonder if qwerty is a generational thing. I was forced to learn qwerty in high school using, yes, actual typewriters. And I distinctly remember just how absurd qwerty appeared to me at first. Today, qwerty is my perferred mode of text input, and I very much want my smart phone to support qwerty as well.
But I am old news in the eyes of the cellular industry. The next generation of computer users, particularly outside the US, have grown up using cellular handsets. These folks might find Fastap to be a better way to input text than qwerty because they never had that required typing class.
Of course, Fastap is going to have to find its way onto a few dozen more handsets before that changeover can begin.
