Motorola Field Tests Wireless Broadband At 300Mbps
cft_128 writes "Motorola Labs just finished field testing its new ODFM (Orthogonal Frequency Division Multiplexing) wireless broadband technology that prove it can attain 300Mbps. This is only a test, but it is an order of magnitude faster than the fiber to the premises that Verizon is now starting to offer. They do mention that the final network would only see 20Mbps sustained and 100Mbps peak."
when does this technology hit the streets?
Suddenly, the iPhone is making a whole lot of sense.

Can't be too long. They think they patented all OFDM technology, it would seem.
"..traveling at typical highway speeds (in excess of 100 kilometers per hour or 62 mph)."
With a connection like that you could easily set up some pretty cool homebrew telemetric systems. Maybe have a community database of good restaurants?

There is a second concern that I can think of. If a phone is able to get broadband speed and has a videocamera attached, it could cause privacy problems. Do we really want a new kind of voyer with these devices??
What else could broadband on a phone be used for?? I doubt anyone will use their cell phone as a computer. A phone is first a phone and secondly all other things. Plus, cell phones have such limited battery use times, that I doubt anyone would really use those other features for more than a very limited time.

It's only an order of magnitude faster than Verizon's offering if there are less than 10 people using it. Wireless spectrum is a shared medium, FTTP is not. Yes, it all gets shared at the internet uplink anyway, but that's beside the point.
Random and weird software I've written.
Who said this was for phones?
Wireless broadband COULD be used for phones *I guess* but it's more likely to be used for people's home PC's or notebook PC's, at least at first.
Wireless technology has a MUCH better chance at rapid deployment in most areas because all you need to do is set up some antennas - whereas with fiber or other wired networks you have to lay down millions of meters of lines to reach everyone's home.
I believe that it's going to be the method of network access for the future. Cheap deployment, fast, and mobile.
Unless you live in NYC or some other major metropolis, don't expect very high speed internet access within the next 10 years or more if you're waiting for verizon's fiber. But if Motorola deploys it's wireless system on a wide scale, you could see it in half that time.

300Mbps until someone fancies a microwave burrito... that's 4 minute of downtime right there.
Multiply that by a decent sized coverage area, TV dinners, reheated coffee, yesterday's pizza and those pastry things that explode if they're in the microwave for too long, but are stone cold if they're not in long enough.... and you're looking at very little actual usable airtime.
I really don't think this can be used for mobile nodes. Power consumption issues with OFDM might relegate this technology for use only with fixed nodes. I don't think we will have a usable laptop adapter for this technology. I have experience using a 802.11a adapter on my laptop and it sucked the life out of my laptop's battery at express speed.
Yeah, Verizon is rolling out their service at 30mbps, and this can attain 300mbps in the lab... well, I've seen 1tbps in the lab over fiber... so touch that wireless! Anyway, I work at a ftth provider, we have 1gbps dedicated to every home, switched network, not shared (like wireless is).
We give up to 50mbps for internet... as our bandwidth gets cheaper, we'll be bumping that up to 100mbps, wireless can't hold anything to fiber.. besides, you can't do reliable voice over wireless (latency issues) and certainly not video which we provide as well, more than 5ms of latency and your video stream is toast...
Wireless will never be a reliable triple play provider, which is the holy grail in telecommunications right now.
I have used fixed wireless as my connection to the internet for over 4 years now. It is a 5mbs link connected to a mountaintop center point about 20 miles away using MMDS technology. I get peak speeds that approach what 3 T-1s would provide at a reasonable monthly fee. Downloads from capable servers provide data at rates of around half a megabyte a second. It is extremely reliable and costs about the same as a cable hookup that would provide only one tenth the speed. For those who say it is not as fast as a fiber hookup, you are correct. However no fiber hookup can compete at these prices (at least not for a while). After the central tower is built the only cost to install is the installation of a pizza box sized antenna on the roof of the home. When compared to the cost of laying fiber to reach homes this is dirt cheap. It is also very reliable - I have experienced about 5 hours of total downtime in over 4 years of use (3 or 4 incidents). I know many cable users that would be happy if they only had 5 hours of downtime in a week. Fixed wireless is a very viable high speed home connection alternative. The main problem with the technology my hookup uses is that line of sight to the central tower is required which makes it a very hard install in the flatter cities. The spread spectrum choice would eliminate that problem. (Mine is microwave based)
