RAHUL AGRAWAL 09CO71 rahulagr2000@gmail.com COMPUTER NETWORKS (CO303) Course Instructor: Mr B R Chandavarkar destine 2 (CNAS2071_rahul_agrawal) Problem Statement: Study and write out front long notes on the features and services provided by animal(prenominal) spirit level in 1G, 2G, 3G and 4G networks. 1. Brief Description of the PHYSICAL LAYER of the transmission control protocol/IP architecture The corporal degree consists of the basic ironware transmittal technologies of a network. It is a fundamental layer fundamental the logical entropy structures of the higher level functions in a network. Due to the overplus of addressable hardware technologies with widely alter characteristics, this is perhaps the just about complex layer in the OSI architecture. The Physical Layer defines the core of transmitting data instants instead than packets over a material link connecting network nodes. The bit stream may be grouped into code lecture or symbols and converte d to a physical signal that is inherited over a hardware transmission medium. The Physical Layer provides an electrical, mechanical, and procedural interface to the transmission medium. In a nutshell, the Physical Layer translates logical communication theory requests from the Data get in touch 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 part of the electromagnetic spectrum is used, what is the overall bandwidth available, how is this ! part into carry? Ensures that mechanisms are available to underwrite utilised bandwidth to pick up coexistence with other users of the same spectrum. ? Propagation - Power levels that are permitted by regulatory authorities in the spectrum in question. The mechanisms are available to control the transmitted power or propagation formula to inform co-channel interference for other users, maximise effective take to the woods or utilise...If you want to get a full essay, order of battle it on our website: OrderCustomPaper.com
