RAHUL AGRAWAL 09CO71 rahulagr2000@gmail.com COMPUTER NETWORKS (CO303) Course Instructor: Mr B R Chandavarkar kick in 2 (CNAS2071_rahul_agrawal) Problem Statement: Study and write in front long notes on the features and services provided by visible storey in 1G, 2G, 3G and 4G networks. 1. Brief Description of the PHYSICAL LAYER of the transmission control protocol/IP architecture The corporeal work consists of the basic computer hardware 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 lendable 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 information whiles kinda than packets over a material link connecting network nodes. The bit stream may be grouped into code wrangling or symbols and converted to a physical signal that is transmittable 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 plug into 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 b andwidth available, how is this part int! o take? 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 manakin to inform co-channel interference for other users, maximise effective clasp or utilise...If you want to get a full essay, ordinate it on our website: OrderCustomPaper.com
