RAHUL AGRAWAL 09CO71 rahulagr2000@gmail.com COMPUTER NETWORKS (CO303) Course instructor: Mr B R Chandavarkar dole out 2 (CNAS2071_rahul_agrawal) Problem averment: Study and write beforehand long notes on the features and function provided by animal(prenominal) mold in 1G, 2G, 3G and 4G networks. 1. Brief translation of the PHYSICAL LAYER of the transmission system control protocol/IP architecture The Physical level consists of the basic ironw ar transmission technologies of a network. It is a fundamental frequency layer underlying the crystal clear entropy structures of the higher level functions in a network. imputable to the all everyplaceplus of forthcoming hardware technologies with widely varying characteristics, this is mayhap the just about interlacing layer in the OSI architecture. The Physical floor defines the core of convey data bits rather than packets over a material radio link connecting network nodes. The bit rate of flow may be classify into code words or symbols and converted to a bodily signal that is transmitted over a hardware transmission medium. The Physical class provides an electrical, mechanical, and adjectival interface to the transmission medium. In a nutshell, the Physical Layer translates logical communication surmise requests from the Data Link Layer into hardware-specific operations to affect transmission or reception of electronic signals. 2.

Physical Layer Technologies/ Features in Wireless Networks The Physical layer takes care of the following issues in wireless data transmission ? Spectrum The set up of the electromagnetic spectrum is used, what is the overall bandwidth available, how is this weaken into channels? Ensures that mechanisms are available to underwrite utilised bandwidth to pick up coexistence with different users of the kindred spectrum. ? Propagation - Power levels that are permitted by regulatory regime in the spectrum in question. The mechanisms are available to control the transmitted part or propagation descriptor to inform co-channel interference for other users, maximise effective function or utilise...If you want to write down a full essay, differentiate it on our website: Orderessay
