Ch3. The Cellular Concept Systems Design Fundamentals

Cellular System rely on an intelligent allocation and reuse of channels. Each B.S. is allocated a group of radio channels to be used within a cell. B.S. in adjacent cells are assigned channel groups which contain completely different channels than neighboring cells. To prevent large interference, optimum.

Channel allocation schemes

In radio resource management for wireless and cellular networks, channel allocation schemes allocate bandwidth and communication channels to base stations, access points and terminal equipment. The objective is to achieve maximum system spectral efficiency in bit/s/Hz/site by means of frequency reuse, but still assure a certain grade of service by avoiding co-channel interference and adjacent.

When a mobile user or mobile terminal crosses the cell boundary or passes out of the range, the signal gets unacceptable. The transition and the process to make the transition are called handoff.The term handoff does not mean a physical change in the assigned channel but rather that the different base station handles the radio communication task.

Cellular network

A cellular network or mobile network is a communication network where the last link is wireless.The network is distributed over land areas called "cells", each served by at least one fixed-location transceiver, but more normally, three cell sites or base transceiver stations.These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and.

Cellular Wireless Networks

Each cellular base station is allocated a group of radio channels within a small geographic area called a cell. Neighboring cells are assigned different channel groups. By limiting the coverage area to within the boundary of the cell, the channel groups may be reused to cover different cells. Keep interference levels within tolerable limits.

ELECTRONICS GURUKULAM: Channel allocation in Cellular System

 · Here, channels are assigned to cells just as in fixed allocation schemes. If a cell needs a channel in excess of the channels previously assigned to it, that cell may borrow a channel from one of its neighboring cells given that a channel is available and use of this channel won't violate frequency reuse requirements.

A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. A repeater sited at a high elevation can allow two mobile stations, otherwise out of line-of-sight propagation range of each other, to communicate. Repeaters are found in professional, commercial, and government.
