 The purpose of a TRC is to multiplex network traffic channels from multiple BSCs onto one 64 Kbits/s PCM channel which reduces network transmission costs. FUNCTION OF MSC:- 1. Switching and call routing 2. Charging 3. Service provisioning 4. Communication with HLR 5. Communication with the VLR 6. Communication with other MSC’s 7. Control of connected BSC’s 8. Direct access to Internet services

Overview, of the typical RF antenna design types used with satellites, both on the ground and on the satellite. This includes satellite television (tv) reception. A variety of forms of antenna can be used for transmitting to and receiving from satellites. The most common type of satellite antenna is the parabolic reflector, however this is not the only type of antenna that can be used. The actual type of antenna will depend upon what the overall application and the requirements.  Antenna gain The distances over which signals travel to some satellites is very large. Geostationary ones are a particular case. This means that path losses are high and accordingly signal levels are low. In addition to this the power levels that can be transmitted by satellites are limited by the fact that all the power has be generated from solar panels. As a result the antennas that are used are often high gain directional varieties. The parabolic reflector is one of the most popular. Antennas...
