Researchers combine full- and half-duplex in same network
Study by NYU and Trinity College Dublin argues that full duplex alone has too many trade-offs, but hybrid network can deliver huge gains

Full duplex technology – which allows radios to transmit and receive on the same frequency at the same time – is seen as one of the most important ways to improve spectral efficiency in emerging wireless networks. However, it has downsides including more limited coverage, so researchers at New York University Tandon School of Engineering and Trinity College, Dublin are proposing a hybrid scheme.
Full duplex – as pioneered by various start-ups, most notably Kumu Networks, which has attracted investment from Cisco, Deutsche Telekom, Swisscom and Verizon –effectively doubles spectral efficiency, by using self-interference cancellation (SIC) to reduce the noise of transmission.
