Investigation of a rural telecommunication system using VSAT technology in Malaysia

This study investigates the VSAT network that is applied to rural telecommunication network. The VSAT network is planned based on telecommunication demand as obtained from the survey. The network uses Measat-1 satellite and existing hub of Maxis located at Shah Alani. Selangor. The network is also based on a star network using access of FDMA-MCPC inbound and a TDM outbound channels. To decide antenna diameter and HPA power of antenna, the satellite link budget is calculated based on the service requirement of BER at 10/sup -7/, 64 kbps inbound information bit rate and BPSK modulation techniques. Rain attenuation is calculated by using the local measured rain rate with 0.01% time of the year that is exceeding 129 mm/h [Hassan, 2002].
