Introduction The demand from social market for high speed broadband communications over wireless media is pushing the requirements of both the mobile and fixed networks. The past decade has witnessed tremendous advancement in the blooming development of mobile communications including mobile-to-mobile and mobile-to-fixed networks. Wireless fixed and cellular networks of future generation will need to support new protocols standards and architecture leading to all IP-based networks. Different systems like digital video broadcasting DVB via satellites have great success commercially as they provide ubiquitous coverage and serve large number of users with high signal quality. Satellite communications have proven to be attractive means to provide communication services such as broadband communications 3G services surveillance remote monitoring intelligent transportation systems navigation traffic warnings and location-based information etc. to fixed and mobile users. However to meet the growing demands of mass market integration of satellites and terrestrial networks seems to be inevitable for future generation wireless networks. Due to technology advances and growing traffic demands communication systems must evolve to completely new systems or within themselves in order to provide broadband services in a safe and efficient way. While enhancements continue to be made to leverage the .
