A Noval Approach For Optimization OF PHYSICAL LAYER FOR WIRELESS AND MOBILE COMMUNICATION

Abstract

In modern era communication is very important. This communication can be divided in two parts (1) Voice and (2) Data. .In voice communication real time data transmission is necessary while data can wait for while. But major area of concern is cost and that is the main reason why we cannot have separate lines for both. In any communication transmission of signal should be secure, error free and least affected by attenuation.  These all can affect signal during transmission in physical layer where little can be done to prevent this. In recent developments in mobile communication has raised the expectation of users to a new height and as demand arises new advancement by mobile companies are also offering newer and faster technologies. In this series the latest development is advancement towards 5 G mobile network with expected data rate over 1 Gbps . This network is expected to roll out around 2020 but a lot of work is pending like infrastructure improvement, architecture development frequency band allotment etc
