Feasibility studies of an integrated terrestrial/satellite network for disaster management

This work investigates the feasibility of an integrated terrestrial/satellite network for use in Disaster Management using Nigeria's NigComSat-1R to provide emergency telecommunication services. The use of NigComSat-1R (42.5°E) on both Ku and Ka bands were analyzed. The worst rain fade calculated was at Calabar and Bayelsa (10.1 dB and 8.8 dB respectively at 99% availability). Calabar gave a rain fade link margin of -0.75 dB at Ka-band, and 1.20 dB at Ku-band (both on NigComSat-1R, but on applying uplink power control from 1 W to 1.5W, the link margin increased to 1.01 dB. NIGCOMSAT-1R on the Ka-band provided the best option with calculated downlink and uplink data rates of 48 Mbps.
