1. An active transceiver array for a wireless telecommunications network comprising:
- a central processing unit and a plurality of calibratable transceiver modules;
the central processing unit comprising a primary signal generation unit;
each transceiver module comprising;
a transceiver chain operable to process a primary signal and generate a processed primary signal;
a comparator unit operable to compare said primary signal and said processed primary signal to determine a transceiver chain error induced by said transceiver chain in said processed primary signal; and
a correction unit which uses the transceiver error to correct said primary signal to be processed by said transceiver chain;
wherein each transceiver chain comprises a digital connection to the central processing unit, a digital to analog converter and an antenna element; and
wherein each module further comprises a coupling, operable to couple the transceiver chain to the comparator unit, the coupling being provided between the digital to analog converter and the antenna element.
