ARLA/CLUSTER: Tecnologia wireless: Rádios que emitem e recebem simultaneamente

[João Gonçalves Costa]

A technology that allows wireless signals to be sent and received simultaneously on a single channel has been developed by Stanford researchers.

Their research could help build faster, more efficient communication networks, at least doubling the speed of existing networks.

These first wireless radios can send and receive signals at the same time, this immediately makes them twice as fast as existing technology, and with further tweaking will likely lead to even faster and more efficient networks in the future.

Researchers are working that if a radio receiver could filter out the signal from its own transmitter, weak incoming signals could be heard.

Their setup takes advantage of the fact that each radio knows exactly what it's transmitting, and hence what its receiver should filter out. The process is similar to noise-cancelling headphones.
