What are the advantages and disadvantages of satellite as a transmission media?

Answer 1

advantages

• used for long distance communication
• high speed data transmission
• many reciver stations can receive signal from the same sender station

disadvantages

• very costly

Answer 2

A Satellite Television system has many benefits and is ideal for many types of people. Some of the advantages are: * People in remote areas can get satellite television even if they are not able to receive cable services. * The picture provided by satellite is far sharper than either cable or off air broadcast. * People who are the technical types and like fixing their own things will love satellite television. * It provides digital information and text services. * Satellite television gives you access to channels and programs that can never be offered through cable. * It gives you news coverage which is live and unedited so you don

Answer 3

I am slightly switched towards Sky TV itself, more than Cable - simply because there is a wider choice of channels, better customer services when you need them, and the cost is pretty much the same.

Sky TV all the way to be honest, and if considering Cable, look at it like this and you might see the reasoning to opt for satellite rather than cable... 37 HD transmissions on Sky TV, and only about 6 on cable.

Hope this helps.

Answer 4

Satellite communication systems are very dependable due to the unlikelyhood of an interruption of the flow of energized communication when compared to other systems, notably terristial radio. Satellite communication systems can be interrupted at those frequencies where rain drops are near the size (length) of the wavelength of the RF, but otherwise clouds nor darkness interfere. Too, the satellite systems must be in line of sight from the ground station and the satellite (unless the one satellite can relay to another distant satellite in a chain of two or more to move the communication beyond line of sight and around the globe). The receive station must be in line of sight of the satellite, too, but not in line with the sending station. Further, the bandwidth is generally greater than most other systems.

Terrestial radio systems that wish to perform beyond the horizon are unreliable due to the changes in the height of the ionosphere, all kinds of radio noise, and variations in RF power and antenna productivity. Due to shared use of the radio spectrum, radio bandwidth is limited compared to satellite systems.

Wire communication systems are only very effective when the wire is continuous between the sender and receiver (not cut) and if the electric power in the wire is great enough to travel by wire over expected distances. Amplifiers can be used to relay a weak wire signal, amplify it, and send it on down the wire. Like ordinary LF, HF, and VHF radio, wires are subseptiable to lighting noise and actual damage, too. Wire has limited bandwidth, but fiber optic systems equal or exceed satellites in bandwidth.

Signal flags (semiphore) and manual waving, flashing lights in Morse Code, yelling by amplified or natural voice, drums and other natural (non electrical) methods are also useful in communication over distances, but have their obvious limitations.

Nothing!! :D
