The present invention discloses novel methods of communication for wireless local loop communication systems. The method comprises the steps of providing a plurality of fixed access units in radio communication with an array of radio fixed parts; utilizing a plurality of radio channels divided into a predetermined number of synchronized time slots; conducting radio communication between an activated fixed access unit and an activated radio fixed part during a chosen time slot on an assigned radio channel; and denying radio communication on said assigned radio channel during said chosen time slot in a controlled number of radio fixed parts surrounding said activated radio fixed parts.
