Full-duplex transmission has been held up as a shining hope for wireless network efficiency for a decade, and has been the subject of many academic and R&D projects, and several high profile start-ups such as Kumu Networks. Full-duplex supports the ability to send and receive on the same channel at the same time, which effectively almost doubles the capacity of given spectrum. However, it has been challenging to implement the technology in a standards-based and affordable way, so scale has been elusive. There have been trials by some large operators, such as Deutsche Telekom, but full-duplex has looked like a clever technology in search of a compelling use case – at least until 5G-Advanced or 6G architectures make it…
