  3. 3. INTRODUCTION WHAT IS WIRELESS ? The word wireless is dictionary defined “having no wires ” . In networking terminology , wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and or microwaves to maintain communications. Wireless networking utilizes specific equipment such as NICs and Routers in place of wires (copper or optical fibre).
  4. 4. 0G TECHNOLOGY(0G – 0.5G) Mobile radio telephone systems preceded modern cellular mobile telephony technology. Since they were the predecessors of the first generation of cellular telephones, these systems are sometimes referred to as 0G (zero generation) systems. It operate on 160 MHz VHF band using frequency modulation on 160 -162 MHz for the mobile unit and 168- 170MHz for base stations. 0.5G is a group of technologies with improved feature than the basic 0G technologies The raw signaling rate is 19.2 kbps, and with Reed- Solomon coding the effective data arte is 14.4 kbps full duplex before control overhead.
  5. 5. 1G TECHNOLOGY 1G refers to the first generation of wireless telephone technology, mobile telecommunications which was first introduced in 1980s and completed in early 1990s. It's Speed was upto 2.4kbps. It allows the voice calls in 1 country. 1G network use Analog Signal. AMPS was first launched in USA in 1G mobile systems.

Within a second we can download the five films that is 20 GB files and upload the 15 GB files or any datum. Therefore it also navigates the satellite networks techniques, hence using the OFDM methodology and FEC for the speed of communication process. It is possible technique only when achieve the higher bandwidth and improves the satellite cell sensitivity with its signal fidelity.
