New Mobile Network Technology at 2.5 GB/Second?

craig.hathaway writes to tell us that Japan's NTT DoCoMo claims to have a prototype wireless network capable of speeds up to 2.5 GB per second. From the article: "MIMO (multiple input, multiple output) uses multiple antennas to send and receive data, as well as specific coding that scrambles and unscrambles the signals produced by those antennas (see "Faster, Farther Wi-Fi"). A base station that uses MIMO technology has multiple antennas that simultaneously receive and send data to and from wireless devices. Unlike base stations with a single antenna, those with MIMO use the multiple antennas to create a number of intertwining channels through which data moves. The jumbled signals are untangled by a 'signal processing' that sorts through the bits."

Technology may be convenient...

...but the review sounds like written by a complete clueless moron.

"The new computer has more gigabytes than the old computer and thanks to these all additional megabytes it's faster. The bits get computered in the additional gigabytes and each gigabyte can work separately so more bits can be computered at the same time resulting in faster computering by the computer."

Oh come on... Where's the news?

Seriously. I've been using several MIMO devices for months now trying to find the right one. And then they post an article where the larger of the only two paragraphs is dedicated to explaining MIMO as if it's brand new.

Uselss

All these technologies risk to become useless because they need time to enter the market in a stable way and time to stabilise and cheapen the technology itself.
Think about the notorious 3G and 4G: a lot of buzzing, but too far from the GSM (aka 2G) and GPRS (aka 2,5G) to be considered a real and useful techology advance,
They should be bale to produce a mobile device able to operate and roam over three or four different network technologies (GSM/GPRS, UMTS, WiFi and 4G) with cost as low as a GSM phone. And it should be cheap enough to be adopted by more and more operators.
This sounds more like a dream than an actual business plan!
