The objective of the invention is to increase the potential hop density of
single frequency TDD radio links by allowing a set of closely located
terminals to use a single channel. This is possible when transmission and
reception periods of the terminals are synchronized so that the transmit
period of any of the terminals in a terminal group does not overlap with
the receive period of any of the terminals in the group. Synchronization
is achieved by selecting at least one terminal in a hub site as a super
master terminal. This terminal gives timing through a common bus to the
rest of the terminals in the group These terminals use the received
timing for adjusting their own timing i.e. for adjusting the starting
moment and ending moment of the transmission and reception periods in
such a manner that none of terminals is sending a burst while another
terminal is receiving.
