Once satellite is in position, earth station can be installed and communication can be established in days or hours. Satellite communication is used in mobile and wireless communication applications. Satellite communications use artificial satellites as relays between a transmitter and a receiver at different locations on Earth. After C, Ku bands it is the Ka band which is hogging the limelight for its high throughput performance capabilities (Excess of 100 Gbps per satellite). Satellite communication usually requires large‐area, high‐gain antennas pointed directly toward the satellite. As urban dwellers, we often overlook the role of satellite technology in providing vital communication links to remote areas where terrestrial networks are unavailable or out of reach. The cell with low traffic speed is called as micro-cells and large high-speed traffic called macro-cells. Cell splitting is a method of subdividing cell into the smaller sized cell. Significant advantages of satellite communication systems over terrestrial communication systems are _____. The satellite transponder converts the signal and sends it down to the second earth station, and this is called Downlink frequency. A Satellite in the Geo Synchronous orbit can cover around 33% of the earth’s surface and can provide … High bandwidth. 3. Wireless and mobile communication applications can be easily established by satellite communication independent of location. ©2017-2020 ecstuff4u.com The content is copyrighted and may not be reproduced. But terrestrial circuits require time consuming installations. Microwave communications are ideal for television and radio broadcasts, while satellite communications are used for communicating to ships and aircrafts, relaying telephone calls and providing communications to remote areas. The two stations can use a relay station for their communication. If you want to learn some different you are the right place for reading so keep reading for a few minutes for the right information regarding satellite communication. More users supported - Cable device have limited slots whereas wireless does not. Disadvantages of satellite communication : The satellite has a life which is about 12-15 years. Satellite Communications: Select all correct answers. here is some basic quick look at some key advantages of satellite communication. Advantages of satellite over terrestrial communication The coverage area of a satellite greatly exceeds that of a terrestrial system. This question appears in Mumbai University > Satellite Communication and Network subject. Once the satellite is in position, earth station can be installed and communication can be established in day or hours. With careful coverage coordination, maximum communications effectiveness is obtained. For communication between remote areas (hilly terrains, island etc) and the main land satellite communication is the only cost effective option. Moreover, visibility from the earth is very short duration which requires fast satellite to satellite handover. We discuss multipath communication architectures and scheduling strategies for … ➨It covers wide area of the earth hence entire country or region can be covered with just one satellite. Satellite communication services being so portable and are very easy to install and also have user-friendly as well, The satellite communication services are very helpful for the people staying in a remote area, The satellite communication services are very helpful for the department of defence where the people on the fields used the wired service every time, This service provides wider bandwidth based on SCPC or MCPC allocation types, It covers a wide area of the earth hence entire country or region can be covered with just one satellite, It is used for mobile as well as wireless communication applications find at independent of location, It also co-exists with terrestrial microwave line of sight communication system, It is easy to install and manage the cost per VSAT site, It does not incur much of costs per VSAT site, It has a small fading margin on the order of about 3 Db, It is easy to obtain service from one single provider and also uniform service is also available, It is used for voice, data and any other information transmission.
