Packet Telephony

Packet Telephony consists of telephony and data tightly coupled on packet based switched multimedia networks. The packet telephony simply refers to the use of personal computers and a packet data network to produce a voice conversation. The goal of packet switched fabric in both LAN and WAN, the vision in to drive voice and data over a single multimedia (packet based N/W) allowing waves to engage in a media rich communication in a natural and straight-forwarded manner. The packet & based fabric is capable of supporting future applications such as video streaming and video conferencing. The transaction to a new paradigm will take years to complete. However technology matures and new application proliferate packet technology will appear in broader market. There is a major distinction between Intranet telephony and VoIP. While VoIP, which usually takes place in managed networks of large corporate is allowed in India. Internet telephony which occurs in public network is not allowed in India.

Multimedia Broadcasting via Satellite

Simply put, a satellite is a microwave receiver, repeater, and regenerator in orbit above the earth. Satellite transmission involves sending signals to an orbiting satellite that receives them, amplifies them, and returns those signals back to earth. The advancement and standardization of satellite transmission technology has created a new opportunity to deliver Internet protocol (IP)-based services to sites around the world. This new opportunity offers exciting possibilities for efficient transmission of streaming and/or large file data from a centralized location to remote sites anywhere in the world.
Multimedia broadcasting by satellite enables the expansion of communications in both the Internet and enterprise businesses. Typically, these applications are ones that already involve or could benefit from the use of video and audio presentations. Satellite delivery is the right solution for the applications described in this document because satellites provide a compelling economic solution, and the wireless connectivity of satellites enables access to areas of countries or regions that have limited access to terrestrial alternatives.

It's great !
