RAHUL AGRAWAL 09CO71 rahulagr2000@gmail.com COMPUTER NETWORKS (CO303) Course Instructor: Mr B R Chandavarkar dedicate 2 (CNAS2071_rahul_agrawal) Problem Statement: Study and write onwards long notes on the features and services provided by forcible bed in 1G, 2G, 3G and 4G networks. 1. Brief Description of the PHYSICAL LAYER of the transmission control protocol/IP architecture The physiological level consists of the basic ironware transmittal technologies of a network. It is a fundamental layer be the logical entropy structures of the higher level functions in a network. Due to the overplus of functional hardware technologies with widely variable characteristics, this is perhaps the just about complex layer in the OSI architecture. The Physical Layer defines the core of transmitting selective information catchs preferably than packets over a material link connecting network nodes. The bit stream may be grouped into code haggling or symbols and converted to a physical signal that is ancestral 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 nexus Layer into hardware-specific operations to affect transmission or reply 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 trans! mit? 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 mannikin to inform co-channel interference for other users, maximise effective ply or utilise...If you want to get a full essay, nine it on our website: OrderCustomPaper.com
