Full duplex radio
Full duplex! Bristol boffins demo Tx and Rx on the same frequency AT THE SAME TIME
Transmitting and receiving on the same radio frequency, at the same time, has been demonstrated by the UK's University of Bristol in a new YouTube video.
The system being used is running 900MHz and 1800MHz with exactly the same equipment.
There are a number of companies working on this technology, called full duplex radio, a technology traditionally viewed as being extremely difficult to implement – if not impossible.
However, what has now seemingly made it possible are improvements in processing, which allows the noise of the transmitted signal to be subtracted from the received signal.
One of the first patents on full duplex was filed by UK-based electronics, defence and telecoms company Plessey in 1980, for a combat radio repeater using the tech. This was called "Groundsat" and was used by the British Army.
