Information on Frequency Division Duplex

Frequency division duplex is a technique in which one frequency band is used to transmit and another used to receive. In other words, one block of the electromagnetic spectrum is allocated for the uplink carrying data from mobile phones to the base station, while a different block of spectrum is allocated to the downlink carrying data from the base station to the mobile phones.
     CDMA mobile phones use frequency division duplex.
