Multiple Distributed Sites with Communication
What happens if, in Figure 11-1, the GSU towers themselves have radios communicating as
shown in Figure 11-2?
Consider GSU 1 and GSU 2: Both collocated towers transmit and receive simultaneously. How-
ever, the radios communicating at GSU 1 and GSU 2 must transmit and receive in turn accord-
ing to the scheme in marked “Normal Phase” in Figure 11-3. This is an impossible situation,
if all the links must send and receive together. It is further complicated by adding a third and
further sites as shown.
