"The typical way to increase capacity on a network is to add more infrastructure, but that's an expensive undertaking. It can also be time consuming and frustrating for network operators who have to get permission to put up new towers, or dig up the ground to lay cables. This is especially true in heavily populated areas where more antennas and traffic disruption are not what anyone wants to see. Rice University has come up with a groundbreaking solution, though. One that promises to at least double the capacity of existing networks with the addition of minimal extra hardware. That solution is full duplex wireless communication. This isn't a new concept, but one that hasn't been possible until now due to the inherent obstacles it throws up."
