This document discusses VSAT, VoIP, and shared internet access. It provides details on VSAT specifications and applications including receive-only and transmit/receive uses. VoIP technologies like softphones, gateways, and codecs are explained. The concept of a shared access network is introduced where a satellite bandwidth is shared between multiple users like a neighborhood network to reduce costs. Wireless options for sharing a high-speed 11Mbps connection are also described.
