The satellites orbit at a persistent altitude and must(prenominal) remain in contact with their partner satellites and stations. Satellite operat es at very high bandwidths but is extremely ! high-priced and complicated. For these reasons this architecture is exclusively used for WANs. Infrared- used for short-distance networks that are in now line of sight. This medium can be operated at speeds of 4 Mbps or less. And Used in layover 2 point and multipoint applications within a confined area e.g. a one room. IrDA (Infrared Data Association) is the standard for...
