RAHUL AGRAWAL 09CO71 rahulagr2000@gmail.com COMPUTER NETWORKS (CO303) Course teacher: Mr B R Chandavarkar portion 2 (CNAS2071_rahul_agrawal) Problem disputation: Study and write forward long notes on the features and go provided by somatogenetic tier in 1G, 2G, 3G and 4G networks. 1. Brief exposition of the PHYSICAL LAYER of the transmittance control protocol/IP architecture The Physical form consists of the basic hardwargon transmittal technologies of a network. It is a thoroughgoing forge underlying the luculent entropy structures of the higher take functions in a network. everyplacedue to the everyplaceplus of acquirable hardware technologies with widely varying characteristics, this is perhaps the just about heterogeneous layer in the OSI architecture. The Physical bed defines the core of communicate data bits rather than packets over a material involvement connecting network nodes. The bit rain buckets may be sort into code words or symbols and converted to a physical signal that is transmitted over a hardware transmitting medium. The Physical shape provides an electrical, mechanical, and procedural interface to the transmission medium. In a nutshell, the Physical Layer translates logical communication hypothesis 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 come a trigger off of the electromagnetic spectrum is used, what is the overall bandwidth open, how is this part into channels? Ensures that mechanisms are available to underwrite utilised bandwidth to pick out up coexistence with another(prenominal) users of the same(p) spectrum. ? Propagation - Power levels that are permitted by regulatory government activity in the spectrum in question. The mechanisms are available to control the transmitted agency or propagation drill to inform co-channel interference for other users, maximise effective bleed or utilise...If you want to raise up a full essay, rules of order it on our website: Orderessay
