Satellite-based fully distributed mesh hybrid networking technology DVB-S2/RCS-WiMAX for RRD areas

Abstract

The convergence of satellite DVB-S2/RCS broadcasting/multicasting systems side by side with terrestrial mobile satellite and broadband wireless 4G WiMAX becomes the most perspective networking technology for BRIC and other countries with many remote, rural, and difficult for access (RRD) territories. The RRD regions differ also by the poor terrestrial core infrastructures and sparsely populated areas. However, the recent broadband satellite systems are based mainly on centralized (i.e., star-like) low-meshed architecture. It requires providing a high concentration of the terrestrial traffics. Hence, such structures are not adequate to the characteristic RRD distributed traffic topology. Therefore the cost of these centralized systems is growing unacceptably for deployment of the 4G public broadband communications in RRD regions. This paper focuses on the developing and the performance analysis of the low-cost, fully distributed (i.e., gridlike) and mesh hybrid networking technology DVB-S2/RCS-WiMAX which meets the RRD requirements.
