Duplexer Radio
What is the need for paired spectrum in the FDD?

The frequency band for cellular communications frequency band pairs and it is difficult to find. What is the frequency of pairs need? If the duplex unit next frquencies required? I wonder why the need for frequency pairs! Do you know why? Tell me, please!

Cell phones can talk to are full duplex (both sides at the same time), so) must have two frequencies, one for each call when FDD Frequency Division Duplex (. It would be possible to use a single frequency, if the code division duplex (CDD), where return paths are somewhat different from the codes were, but not how the system was created.
