From ComputerWorld: Fujitsu is developing technology that doubles the capacity of individual cells in cellular networks through task-sharing and efficient scheduling.
The approach effectively allows for transmission and reception of radio signals on the same frequency. The company sees it as a step toward the next stage in cellular network standards.
Since the current radio spectrum used by 4G/LTE leaves little room for the deluge of data expected as mobile devices proliferate, researchers have been trying to increase capacity by using the same frequency for simultaneous transmission and reception, a technique known as full duplex.
Users could enjoy the same speeds and capacity with only half the spectrum, and it could save carriers billions of dollars on auctions for spectrum licenses.
But providing simultaneous transmission and reception on the same frequency has proven very elusive because of the massive interference caused by transmitting signals, which can leak into adjacent receivers.
