story category Clearwire Shows Off Mobile WiMax In San Fran
2-4Mbps, with spikes up to 10Mbps....

Clearwire has apparently set up four, three-sector towers near the CTIA Fall 2008 trade show in San Francisco this week to demonstrate their mobile WiMax service under no-so-real-world conditions. According to the company, they're seeing average speeds between 2-4Mbps in areas where they're deploying the technology. "We've seen up to 10 megs down," says Clearwire's VP of network deployment, John Storch. Clearwire is using the temporary towers in San Fran to take conference attendees on fifteen minute driving demonstrations of the technology (see pics of the rigged van).

Can it be that Wimax may really happen sometime in next yr?

Is Wimax really, truly going to turn from vaporware in to a real product over the next 12 months with all that cable & Intel money paving the way?

Why is this impressive?

They are currently using 5 Mbps WiMax here in Utah for the UTA TRAXX light rail system:

Conduit and fiber optic cables installed under the tracks allowed UTA to build a very robust WiMax backhaul system.
Fiber backhaul system connects to a dedicated 20 megabits per second ISP.
The rail corridor features 28 WiMax towers that connect the fiber backhaul system to the trains by broadcasting a 5 megabit WiMax connection to access points on board each car.
The access points then broadcast the WiFi to users seated anywhere on the train.
Train cars also feature an ATT 3G data backup network that maintains a continuous connection with WiFi users to prevent any loss of signal in the event of a drop from the WiMax system.

They already have an average of 1000 people per day that use this system. We take mobile broadband internet connectivity very seriously here in Utah. I have a carpc with a 3G EV-DO connection, just waiting for the day I can switch over to WiMax.

Re: Why is this impressive?

I'd pose the same question to you. What is so much more impressive about the system you have described as opposed to a citywide mobile WiMAX network?

Re: Why is this impressive?

Because a functional citywide WiMax network is not yet a reality for most of us. All we really need to do is add some more towers here and it would make this hyped SF system look like the nonsense that it is.
Oh, did I mention that the TRAXX WiFi network is FREE to use by any passenger? I hope you all enjoy making Clearwire investors rich, and while you all waste your money on slow ISP's, we will continue to enjoy our 50 Mbps Utopia connections.

San Juan, PR		 AFAOK the Utah system uses Redline AN80 Backhaul units, they are not Wimax. They are fixed wireless with a propietary protocol

Re: Why is this impressive?

The Redline AN80 is just an ethernet bridge. Are you saying that Utah lies when it states that its system is WiMax? ROTFLMAO

Its still considered WiMax so what does the equipment have to do with it? Are you saying that Utah lies when it states that its system is WiMax? ROTFLMAO
I believe you've misunderstood what he said.

They are not using "WiMax" for "Backhaul"....from what I see in that "press" release...they are using fiber to feed "WiMax" towers along the track, which in turn feed the wireless signal into the passing trains.

Re: Why is this impressive?

Exactly why would it be called a "WiMax Tower" if it did not use WiMax technology? The fact that the passengers are using WiFi to connect to a WiMax router makes very little difference, theres just not a whole lot of WiMax PC adapters available yet, ya know.

Please re-read what was posted.

He said the "BackHaul" portion was NOT WiMax...he never said anything about the towers that feed the trains.

This article is about MOBILE WiMax, not fixed WiMax. Clearwire has offered fixed WiMax here for 3+ years now. There is a big difference in the two technologies.

Re: Why is this impressive?

Well exactly what speed do you consider "mobile" then, is 79 mph not quite up to your expectations? The same system is used by the UTA bus fleet. If I had the same equipment in my car I would be good to go, what is so hard to understand there?

No, they are using fixed WiMax to get the signal to standard WiFi access points. Mobile WiMax doesn't require an intermediate WiFi access point. It's straight WiMax to the laptop, cell phone, whatever, at the speeds listed.

Cha-Ching!

For what it's worth, Clearwire just signed a $173 million agreement with Florida Atlantic University to lease its unused broadband spectrum for the next 30 years. Selling thin air in South Florida has never paid so well.

"Storch says that Clearwire has been getting average download speeds of 4 Mbit/s and uplinks of 2 Mbit/s on the network."

That's cool!
