Abstract

Migration of frequencies has become a necessity to accommodate higher number of user and applications for future technology advancement. In Malaysia, the migration of C-band to accommodate fixed satellite services (FSS) has been made by the Malaysian Communication and Multimedia Commissions (MCMC) by the migration from MEASAT 1 to MEASAT 3. The frequencies range assignment has changed from between 3700 MHz to 4200 MHz and 5925 MHz to 6425MHz; to the frequency range of between 3400MHz to 3700MHz and 6425MHz and 6725MHz; an expansion of 300MHz. At the same time, the number of transponder has also increased from 12 transponders to 24 transponders. With changes in frequency range and number of transponders, the Received Coverage Area (RCA) is also changed. This is because RCA is directly influence by changes in the minimum elevation angle caused by change in the satellite altitude. The deployment of new satellite also introduces an economic impact in relation of the environment at which the satellite is deployed because the interference on the signal will greatly influence the offered service. Satellite altitude for MEASAT 1 is lower than MEASAT 3; giving higher interference in MEASAT 3. At the same time, the minimum elevation angle of MEASAT 3 is higher than MEASAT 1 therefore resulting in lower coverage area. However, higher frequency means a lighter weight and smaller satellite with lower power that reduce the cost of MEASAT 3. In long run, MEASAT 3 is seen as an essential migration because of its flexibility in design, able to operate in both C-band and Ku-band, overcome the congestion in the current C-band and most importantly, MEASAT 3 will allow a wider coverage inside and outside of Malaysia's territory which could have a huge economic impact for Malaysia.
