Abstract: This article is proposed to different types and bandwidth demands keep climbing, third and of mobile network communications between the fourth generation (3G and 4G) devices and wireless networks. In the past few decades, mobile wireless networks have become common place. 5G has technologies have experience 4G or 5G generations speeds which is way better than what 4G offers. It is of technology revolution and evolution, namely a very high bandwidth and wireless mobile from 5.5G (10G network) supports a variety of multimedia internet networks can be completely TDS services, but is not necessarily directly wireless communication without limitation, which correlated with individual customer Internet speed makes perfect wireless real world – World Wide availability. TDS 10G network enables services like Wireless Web (WWWW). 5.5G (10G network)TDS TV, TDS and managed IP Hosted, and high-speed is the “backbone network” that connects TDS residential and commercial Internet service. markets to each other, to our data centers, and to the Satellite network will be used from 6G mobile Internet. The 6G of wireless mobile communication communication systems onwards. In 6G the cost of network must integrate satellites so that it can go mobile call will be relatively high but in 7G this fully global and cover more areas. The next problem will be improved and the cost of call will generation could be 7G which is the most advance be reduced and lower level user will benefit from it and may unite other generations. Therefore i7.5G or moving towards all the latest development that has 8G also navigates the satellite networks techniques, been done up to 7.5G or 8Gconnectivity. hence using the OFDM methodology and FEC for the speed of communication process. It is possible Keyword : 0G to 5G, 5.5G to 7.5G or 8G mobile technique only when achieve the higher bandwidth network communications. and improves the satellite cell sensitivity with its signal fidelity. I. INTRODUCTION The idea of wireless communication predates the discovery of "radio, derived from Latin word II. EVOLUTION "radius", meaning "spoke of a wheel, beam of light, ray"" with experiments in "wireless telegraphy" via What is Wireless? The word wireless is dictionary inductive and capacitive induction and transmission defined “having no wires”. In networking through ground, water, and even train tracks since terminology, wireless is the term used to describe 1830. Now a day’s mobile phones got much smarter any computer network is no physical wired due its capability to record, play, stream, upload, connection between sender and receiver, but rather download – audio and video, capture images, share the network is connected by radio waves and or data via Bluetooth and Wi-Fi, browsing internet, microwaves to maintain communications. Wireless voice and video calling, etc. Wireless networking utilizes specific equipment such as communication is the transfer/distribution of data / NICs and Routers in place of wires (copper or information between two or more points using radio optical fibre). waves (wireless) i.e. without connecting electrical conductor. The first generation (1G) of cell What is the necessity of Wireless Communication? technology was analog, with no signal compression Wireless technology can offer businesses more or manipulation of any kind.

It can be used in different cells. for services such as Wireless Application Protocol (WAP) access, Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web access. 2.75 – EDGE is an abbreviation for Enhanced Data rates for GSM Evolution. EDGE technology is an extended version of GSM. It allows the clear and fast transmission of data and information up to 384kbit/s speed. Fig1.
