The High speed micro wave communication link is requirement to fulfill the ever increasing tele-communication needs with high QoS at Low CoS. The systems developed till date is named as per their frequency of operation LF, MW, HF, V/UHF, Microwave and cellular communication.Latest of all is cellular communication and are of two types firstly GSM (Global System for Mobile Communication), Secondly CDMA (Coded Division Multiple Access). Both the systems are used for providing communication at all times/places. A boom is underway in case of GSM. Standard set developed by the European Tele communications Standards Institute (ETSI) to describe protocols for generation (2G). The GSM standard was developed as a replacement for (1G) first Generation cellular network & optimized for full duplex voice telephony. This was expanded over time for including data communication by Circuit switched transport, packet data transport via GPRS (General Packet Radio Services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS). Further improvements were made when the 3GPP developed third generation (3G) UMTS standards followed by fourth generation (4G) LTE Advanced standards. This paper explains the developments in the field of communication, services provided, causes of link degradation, the various methods used to overcome the problems and the advantagesof high speed microwave comunication
