Tom Marzetta, the leader of Bell Labs' communications and signal processing research group in Murray Hill, New Jersey, is working on the successor to 4G mobile communication.
Although it is in a very early stage — no working prototype has yet been created — his system would see 400 antennae on one base station. This would theoretically allow for 20 times the bandwidth of long-term evolution, the replacement for 3G that is just starting to be deployed now.
"We haven't been able to come up with a catchy name," Marzetta said, adding that 'massive MIMO' and 'large-scale MIMO' are candidates.
