yes, at least in a limited CONTEXT. Some of the proposed benefits of 5G are only POSSIBLE if technology is developed that allows full depleting (sending and receiving, or uplink and downlink) simultaneously on a SINGLE chip small enough to fit into a Smartphone. This seems really difficult or impossible to achieve, since signals so physically close to each other inevitably INTERFERE. A team from Columbia University seems to have developed a preliminary solution, by embedding interference-cancellation circuits in what they CALL a ‘noise and leakage canceling receiver’ that works between 0.3 and 1.7 GHz on a CMOS design chip, The Register reports.
