Frequency (Cellular)

Sets of frequency ranges allocated among mobile networks for mobile phone use. Cell phone repeaters are created to improve different frequencies.

Full duplex

Communication signal exchange goes the following way:

Cell Tower>>Donor antenna>>Repeater Outdoor downlink (amplifies signals)>>Sever antenna>> Mobile phone (receives signal after amplification). After it communication goes in reverse order: the phone (transmits signal)>>Sever antenna>>Repeater indoor uplink>>Donor antenna>>Cell Tower.

To put it shortly, the signal goes in two directions: to phone and from it.
