Satellite Cell On Wheels
Major Factors To Be Considered
Synchronization – Satellite Modem provide PRS at NodeB
Satellite Roundtrip Delay – expected between 500-550ms
Satellite Link Capacity – 2xE1 being used,
Frame Synchronization – Both uplink and downlink widow needs to be increase to cover the satellite delay
MAC/RLC Parameters/Timers – need modification to support satellite link delay

Satellite Cell On Wheels
Design and Deployment
Synchronization
The PRC from satellite modem wasn’t stable enough, a high accuracy clock controlled by GPS being deployed
Satellite Roundtrip Delay
The controlFrameT window increase to 800ms to cover the delay
Satellite Link Capacity
Result in limited CS & PS traffic capacity
