It ensures that the communication will continue without user’s sessions or connections being dropped. Terminologies: Mobile Node (MN): It is the hand-held communication device that the user caries e.g. Cell phone. Home Network: It is a network to which the mobile node originally belongs to as per its assigned IP address (home address). Home Agent (HA): It is a router in home network to which the mobile node was originally connec...
Covers Satellite Communications, GSM specification and explain functional architecture of GSM , Introduction to Wireless LAN and IEEE 802.11, WIRELESS LANS AND PANS, Multiplexing, MULTIPLE ACCESS TECHNIQUES Satellite Communications Overview Basics of Satellites Types of Satellites Capacity Allocation Basics : HOW DO SATELLITES WORK Two stations on Earth want to communicate through radio broadcast but are too far away to use conventional means. The two stations can use a satellite as a relay station for their communication One Earth Station sends a transmission to the satellite. This is called a Uplink. The satellite Transponder converts the signal and sends it down to the second earth station. This is called a Downlink. ADVANTAGES OF SATELLITES The advantages of satellite communication over terrestrial communication are: The coverage area of a satellite greatly exceeds that of a terrestrial system. Transmission cost of a satellite is independent of the distance from t...
