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
