U-Base stations
At these points the selected limit value should be measured.
If uninterrupted telephony is to be guaranteed, the next transmitters must also be visible with
–70 dBm at these –70 dBm points shown by the previous transmitter. Next walk around the entire
radio hop, determine the corresponding locations of the transmitters, and enter them in your plan.
IP-Base stations
• As the base stations synchronise among themselves, it is imperative that they are in sight of one
another, i.e. a base station must not be positioned further away than a maximum of –70dBm from
the next base station, base stations included. Ideally however at least two base stations within a
cluster should be in sight so that synchronisation is accelerated and
is increased
