Fujitsu develops tech to double capacity in wireless cells

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.

Fujitsu hopes to enable wireless carriers to make better use of infrastructure and spectrum resources by allowing simultaneous transmission and reception on the same frequencies.
