The engineers achieved this feat by implementing the first ‘on-chip RF circulator’ which allows both incoming and outgoing signals to be sent and received using just one antenna.
In the era of Big Data, the current frequency spectrum crisis is one of the biggest challenges researchers are grappling with and it is clear that today's wireless networks will not be able to support tomorrow's data deluge.
Today's standards, such as 4G/LTE, already support 40 different frequency bands, and there is no space left at radio frequencies for future expansion.
At the same time, the grand challenge of the next-generation 5G network is to increase the data capacity by 1,000 times.
The new duplex system enables simultaneous transmission and reception at the same frequency in a wireless radio by using switches to rotate the signal across a set of capacitors.
Full-duplex communication is of particular interest to researchers...
