Optimizations

The result of user traffic and TDMA calculation for this network was a total modem data rate
requirement of 8625 kbps. Preliminary link calculation showed that a single carrier solution
would lead to a very high power requirement for the earth stations.
Therefore it was decided to split the capacity into two carriers, the master stations using carrier
1 and the slave stations carrier 2. The following requirements were defined:
Topology
Modem rate [kbps]
Gross container size [Byte]
BER max.
Rain availability min. [%]
