WiFi capacity doubled at less than half the size

[RocketmanDan]

EurekAlert reports that Engineering researchers at the Columbia University if Engineering and Applied Science have discovered a way to have a WiFi chip transmit and receive on the same frequency on a single antenna simultaneously, massively increasing the throughput capacity. I think this is great. It can only mean further improvements in wireless technology and the researchers at the university have something to be proud of.

"Our circulator is the first to be put on a silicon chip, and we get literally orders of magnitude better performance than prior work. Full-duplex communications, where the transmitter and the receiver operate at the same time and at the same frequency, has become a critical research area and now we've shown that WiFi capacity can be doubled on a nanoscale silicon chip with a single antenna. This has enormous implications for devices like smartphones and tablets."

EE Times say that funding is being provided so that carriers are encouraged to adopt the technology so that it can be implemented more quickly and hopefully be put into effect relatively cheaply.

If adopted by carriers—and major wireless chip makers are now providing funding—wireless communications will soon be able to double its throughput at virtually no extra cost—trading a chip for a second antenna.

Interesting stuff.

Oh that's so going to screw with interference we already have if you put multiple people on the same channel/frequency. Watch.
