There is a further restriction: If there are two distributed sites transmitting to each other,
they must both use the same RFP. This requirement, together with use of shifted transmis‐
sion phase (item 3 below), ensures that communicating distributed sites to not interfere
with each other by transmitting simultaneously.
Two GSU managed sites transmitting with shifted transmission phase and using the same
RFP, transmit one half a RFD apart (see Figure
2. Setting the Tx Transmission Ratio
Since the GSU is always HSM, it must be able to cater for hub site RADWIN 2000 C and
later ‐ based links. (See the RADWIN 2000 User Manual, Chapter 5). If you use asymmetric
