Development of broadband data is growing rapidly across the world. In areas lacking fixed broadband infrastructure, mobile networks are expected to play a major role as it has been the case in rural areas here Second Generation (2G) GSM has been the predominant way to provide voice and text services. Satellite can be used for mobile backhaul when the distance between the base station equipment and the core of the network is too large for microwave to be economically viable.
Backhauling third Generation (3G) and Fourth Generation (4G) mobile through satellite brings also new challenges to cope with delay sensitive traffic, synchronization and data throughput and cost performance.
While satellite backhaul, for 2G networks, were focused on reducing the bandwidth required to transport voice, optimization for 3G/4G focus on data transmission. Available solutions include header data compression, web and video acceleration, and caching. Typical applications of 3G/4G backhaul by satellite include: Read More
