1. A cellular base station telecommunication system comprising:
- a. at a first site, a first cellular base station comprising a first group of base station antennas controlled by a first local controller, each antenna having a controllable electrical or mechanical parameter, each antenna further having two or more radiating elements and an electromechanical structure responsive to externally supplied control signals and configured to effect relative movement of components of one or more phase shifting elements to vary the phase of signals supplied to the respective radiating elements to vary a direction of a beam of the antenna;
b. at a second site, a second cellular base station comprising a second group of base station antennas controlled by a second local controller;
each antenna having a controllable electrical or mechanical parameter, each antenna further having two or more radiating elements and an electromechanical structure responsive to externally supplied control signals and configured to effect relative movement of components of one or more phase shifting elements to vary the phase of signals supplied to the respective radiating elements to vary a direction of a beam of the antenna; and
c. a central controller communicating with said first and second local controllers and configured to control said parameter in one or more of the antennas of said groups of antennas.
