I've met the FiberTower guy on a site once. [A non-XOHM one..] They were stretched very thin, personpower-wise. DragonWire has glossy but uninformative web pages. What either provider boils down to is: do they have enough spectrum under license where you need bandwidth, or not?
We're talking Bandwidth here folks. Figure 40-60 MB *per tower site* to do the job right. And they likely have hundreds of sites in the DC/B'more area. [Think of what the data pipeline into the MSO must look like..]
I've heard stories about how muchXXXXlittle XOHM is starting out with, and it's no Jack Kennedy. So it will be interesting to see how much XOHM delivers, and how long the honeymoon is before it too gets bandwidth caps announced. |

Quoted from the article:
"According to the WiMAX Forum, worldwide WiMAX customers will exceed 200 million by 2012, generating US$7.7 billion in equipment sales."
If that truly is a worldwide estimate, it sure makes one doubt any wide availability here in the USA in the foreseeable future. Sadly.

Clearwire says it still expects to close the WiMax JV with Sprint Nextel sometime in the 4Q of this year. A company spokeswoman said "We continue to believe that the approval process is on track to permit closing before the end of the year,"

If WiMax works as published in the large city markets, it could put Sprint back in the game an independent telco player.
While I am disgusted with the way it has handled the 5 GB cap issue, I would like to see it remain independent for the sake of competition and for its history of pursuing new technologies.

 Besides, my data contract runs out next month and both Clearwire and Sprint serve the Reno market. I'm ready for a new combo data card and service.

| What I want to know is when can I use this when I'm parked at a rest area in the middle of Kansas, Michigan, or some other remote place like I can with EVDO now and not worry about 5 gig limits? Truth be told, I have no problem at all locating a hotspot in Baltimore or Chicago so why or when should I be impressed? |

End user access and performance is certainly the bottom line. WiMax and WiFi are really not fundamentally different in respect to technologies. They each have to obey physics and they each serve to deliver bits to/from the user. It could even be argued that with some tweaking to a WiFi standard to reduce the low-end data rate and provide performance down to the -100 dBm region, 802.11 (especially b) might have been used in the same manner as WiMax.
There are certainly other issues like sharing, handoff, quality-of-service but fundamentally the two do similar things. It's been suggested that WiMax has been rising to fame primarily because Intel missed the WiFi bandwagon, wants to sell wireless silicon into every wireless device and arranged the marketing muscle and made the contacts to further that.
So, a reason for being truly impressed is that a carrier or carriers manages to roll out a large enough network that operates well enough that anywhere you go you can do on it something you can't do with WiFi hotspots. The carriers do have access to a lot of sites, even if most of them don't own the sites anymore.It's not just Sprint that doesn't seem to care to own their network hardware, Crown Castle and the other biggies are the heavyweights here, not the carriers.
Neither WiMax nor WiFi do well at high data rates unless there is adequate signal, generaly in the -65 dBm region for 10's of Mbps. Ask yourself in how many regions you frequent and want service you have this kind of signal level from Wifi and how many from mobile carriers (any carrier). Remember that the difference between this sort of signal strength and the -105 dBm sort of level that a voice call might require is at least 1000:1 and perhaps 10,000:1.
What would be impressive would be to see a large fraction of the US blanketed with coverage at those kinds of signal levels enabling the *mobile* user to have high quality and high rate access to information. That would be impressive because it could enable really new services, like turning the camera around on your mobile vision-phone and communicating in full-rate or even HDTV.
In my opinion it's the network that would make things impressive for mobile users, not the particular protocol.

Clearwire holders will get shares in Sprint WiMax JV
"Clearwire Corp said on Friday that it would issue its shareholders about $1.62 billion worth of shares in its wireless joint venture with Sprint Nextel Corp in exchange for their existing Clearwire shares."

Network World is reporting Sprint WiMax is scheduled to launch first in Baltimore, then in Washington, D.C., and Chicago by the end of this year. Next to launch in 2009 will be Philadelphia, Boston, Providence, Rhode Island, and Dallas/Fort Worth, Texas. Clearwire expects to launch mobile WiMax in Atlanta, Las Vegas, Portland, Oregon, and Grand Rapids, Michigan, in 2008.

So how about all points in between? Clearwire has been offering service in my town, Dayton, Ohio for over a year now. I Have Roadrunner, don't need Clearwire. I cant use EITHER Clearwire or Roadrunner but a few days a month when I happen to be home. One day I'm in Paulsboro NJ, The next I'm in Hamilton, Ohio, the next Lenexa, Kansas, Today I'm outside of St Louis. I have no clue where I'll end up tomorrow. I'm just wondering how long will it take for this to benefit me?
And another thing....Why does Sprint have to be in charge of it? Knowing their track record, they will come out with some new fangled revolutionary phone/pda that controls the weather or beams people across the country or something ridiculous then tell us laptop users to stop hogging all the bandwidth. |
