between multiple analog inputs using the frequency-division multiplexing technique. In transmitting wirelessly‚ a laser and photodiode are used instead of antennas. This choice is made because it is complex to build a Frequency Shift Keying (FSK) circuit. Without FSK‚ an antenna would need to be 75km long in order to transmit a wave of 4 kHz. 1.2 Problem Identification In this project‚ a laser pointer is used to transmit analog signal wirelessly. In order to realize digital transmission‚ the analog

| | IntroductionThe term “computer network’’ means a collection of autonomous computers interconnected by a single technology. Two computers are said to be interconnected if they are able to exchange information. The connection need not be via a copper wire; fiber optics‚ microwaves‚ infrared‚ and communication satellites can also be used. Networks come in many sizes‚ shapes and forms. Uses of Computer Networks 1. Business Applications 2. Home Applications 3. Mobile Users 4. Social Issues

ABSTRACT 4G TECHNOLOGIES Wireless technology has transformed our lives in many ways. Until very recently‚ we needed a computer wired to a port‚ to get online. Even wired telephones are becoming a thing of past. Nowadays‚ we use our mobile phones for banking‚ to check ticket availability at a Cinema Hall‚ and many more. Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”. And‚ Wireless networking refers to any kind
