Airgo Quadruples Wi-Fi Limit

QED writes "Airgo Networks, a privately held maker of wireless networking components, said on Wednesday it has developed chips that will increase the Wi-Fi speed limit by a factor of four. The Palo Alto, California-based company, which designs its chipsets around Multiple Input and Multiple Output (MIMO), a wireless technique that uses different radio channels to improve both speed and transmission quality, said it has achieved data rates up to 240 megabits per second (Mbps)...

Thanks for the response, much appreciated.

I do that occasionally - come out with a massively wrong pedantic response, hoping to bring out the standards people and engineers who worked on the thing, just to see how bad the SNR is around here. Glad to see it's still not terrible. It's good to see people come out and defend stuff.

Please mod grandparent back down. Some people don't know how to read background to see that what I'm quoting is terribly wrong, and shouldn't be modded "Informative".

My 2001 project was on the usefulness of 2-MIMO to increase throughput at the fringes of wireless networks. Differential (MIMO vs. SISO) throughput turns out to follow a Rayleigh distribution as one gets out towards the fringes. I also modeled multipath, loss, and scattering in office environments. Measured signal granularity was significant, with nulls of -20dBm below average signal level on scales of half the wavelength at 2.4GHz. Average signal power over a given channel varied with a time constant of about 5000ms*dBm, both in the 2.4GHz and 5Ghz range.

MIMO-OFDM is going to work wonders on throughput and range with the True MIMO chipset, and I can't wait to get some of Airgo's stuff on the range here.

I'm writing a college textbook using the Linksys WRT54G and firmware for a networking lab (coming soon). And if you used the (large-networking-company) 340 series back in the day, I simulated and tweaked the antennas and tested the hell out of it in a massive site survey.

Don't worry, I'm a believer. Airgo's a cool company. :)
