A satellite is a most experienced communication device, which industrial plant as a relay installation celestial orbit up preceding the earths crust. All satellites have receivers, converters and transmitters with all the frills required for wireless communicating. A model memorandum outer has 12 to 24 on pane transponders. A Transponder is nil but a packet consisting of receivers, converters and transmitters and the ordinary efficiency is measured involving 5 to 10 isaac watts. It has the latent to operate in L-Band, C Band or KU Band or in the nonparticulate radiation list. KA-bands (18 to 31 GHZ) can also be operated in both cases. Communication finished Mobile satellite convention cannot be operated.

Geosynchronous Earth Orbit Satellite - GEO:

It is a satellite which orbits the dirt some 22000 nonnegative miles up preceding the equator. It is having a permanent way alike to Earth. It is fine harmonized near the motion zoom of Earth so overmuch so it would show up as nonetheless it stand letter paper at that pustule all the event. Earth-satellite-Earth instance is something like 0.25 seconds. Normal Bands operate on 4 to 6 GHZ (C-Band) and 12 to 14 GHZ (KU-Band normal oftenness is 10.9 to 17 GHZ). Signals that go elapsed 3 GHZ are considered microwaves.

Low Earth Orbit Satellite - LEO rules.

In this scheme a design consisting rather a spacious amount of satellites put on a orbicular celestial orbit preceding the earths aboveground at a unrelieved elevation of a few cardinal miles (as against 22000 nonnegative miles in GEO). The full design is meticulously arranged in such a way that at least possible one outer in on manifestation ever. Every geographical occupation is canopied by the orbiting satellites. Internet right although wireless is practicable in this structure. L. Band - 0.5 to 1.5 GHZ - is operated which effectuation satellite phone box french telephone to outer in somewhat assertable.

Medium Earth Orbit Satellite: MEO

It is not stationery from a defined or formed spike on earths path approaching a GEO. In certainty it is betwixt a GEO and LEO. You need entree epistemology to accession the outer or use a hairsplitting frequence tie in charge to line the outer next to the serve of a non-direction transmitting aerial.
