Iub Interface Over Satellite
(Share of Telstra SatCOW Project Experience)
Satellite Cell On Wheels Project Objective Design and set up a transportable mobile base station capable of using satellite transmission to link back into the Next G network, that could dramatically expedite mobile network disaster recovery within 2 hours
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
link delay
Parameters/Timers – need modification to support satellite
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
