University of Bristol Showcase (Potentially 5G) Full Duplex Tech

Full-duplex tech

The University of Bristol will demonstrate a prototype for single antenna full–duplex radio, a candidate air interface technology for 5G which could double the capacity of wireless systems.

“the preferred choice for operators when upgrading to 5G networks”

Full-duplex radio is a transceiver which can transmit and receive at the same time and in the same frequency band. The prototype will have electrical balance duplexing to allow for this dual capability.

A spokesperson claimed it will be ‘the preferred choice for operators when upgrading to 5G networks’ and described it as ‘a breakthrough that has important ramifications for spectral efficiency by potentially doubling the capacity of wireless systems and could allow unrestricted international roaming’.

“Self-interference cancelling technology will take priority”

The technology was associated with 5G during SK Telecom’s activity at the World IT Show in Seoul last month, as well as in recent Chinese research. Canada’s University of Waterloo has also claimed to have ‘the best worldwide’ full-duplex node in it’s 5G work. Kumu Networks is probably the best known developer of Full Duplex radio so far.

University of Bristol PhD student, Leo Laughlin, will present the demo at the Cambridge Wireless (CW) Radio SIG meeting which will take place on Wednesday 8th July at the institution’s School of Chemistry.

Self-interference cancelling technology is the key enabler for full duplex transmit/receive.
