What is reuse factor?
The frequency reuse factor is defined as 1 over the number of cells in the cluster of the system.
Valid clusters are those that result in 6 cells with the same frequency of a particular cell located at equal distance from it..
How can I increase cellular network capacity?
Cell splitting is the process of subdividing a congested cell into smaller cells, each with its own base station and a corresponding reduction in antenna height and transmitter power. Cell splitting increases the capacity of a cellular system since it increases the number of times that channels are reused.
What is the condition for handoff?
Explanation: Handoff occurs when a mobile moves into a different cell while a conversation is in progress. The MSC automatically transfers the call to a new channel belonging to the new base station. 2. Handoff does not require voice and control channel to be allocated to channels associated with the new base station.
Which type of handoff is used in CDMA?
Soft handover or soft handoff refers to a feature used by the CDMA and W-CDMA standards, where a cell phone is simultaneously connected to two or more cells (or cell sectors) during a call. If the sectors are from the same physical cell site (a sectorised site), it is referred to as softer handoff.
What is the frequency reuse concept useful in cellular communication?
Frequency reusing is the concept of using the same radio frequencies within a given area, that are separated by considerable distance, with minimal interference, to establish communication. For example, when N cells are using the same number of frequencies and K be the total number of frequencies used in systems.
How do you find the frequency reuse factor?
The frequency reuse factor of a cellular system is 1/N,since each cell within a cluster is assigned 1/N of the total available channels in the system. In this example, N = 19 (i.e., i = 3, j = 2). Where, i and j are non-negative integers. To find the nearest co-channel neighbours of a particular cell, a.
Why cellular communication is required?
This process allows millions of cells to communicate and work together to perform important bodily processes that are necessary for survival. … Both multicellular and unicellular organisms heavily rely on cell-cell communication.
What is meant by frequency reuse?
Technique for using a specified range of frequencies more than once in the same radio system so that the total capacity of the system is increased without increasing its allocated bandwidth.
What is the major concern in frequency reuse?
1 Frequency Reuse. Covering a large geographic area with limited amount of spectrum leads to the reuse of the same frequency in multiple locations; this leads to co-channel interference considerations, meaning interference from different areas (or cells) that use the same frequency channel.
Why the size of the cell is kept small in cellular network?
Explanation: The size of the cells in cellular network is kept small because of the need of high capacity in areas with high user density and reduced size and cost of base station electronics. 12. What is handoff?
What is the purpose of frequency?
A frequency distribution is an overview of all distinct values in some variable and the number of times they occur. That is, a frequency distribution tells how frequencies are distributed over values. Frequency distributions are mostly used for summarizing categorical variables.
What is the use of frequency?
Frequency measures the number of times something occurs in a specific amount of time. … While frequency can be used to measure the rate of any action, in technical applications it is typically used to measure wave rates or processing speed.
Why the shape of cell is not circle?
Why the shape of cell is not circle? Explanation: Circle is the first natural choice to represent the coverage area of a base station. But while adopting this shape, adjacent cells cannot be overlaid upon a map without leaving gaps or creating overlapping regions.
How does frequency reuse enhance cellular network capacity?
Frequency reuse improve the spectral efficiency and signal Quality (QoS). … In Frequency Reuse scheme, total bandwidth is divided into different sub-bands that are used by cells. Frequency reuse scheme allow WiMax system operators to reuse the same frequencies at different cell sites.
What is frequency reuse concept in cellular communication ques 10?
Cellular phone networks use cellular frequency reuse. In the cellular reuse concept, frequencies allocated to the service are reused in a regular pattern of areas, called “cells”, each covered by one base station. In mobile-telephone nets these cells are usually hexagonal.
What is meant by frequency?
Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Which is one of the disadvantages of 2g standards?
The downsides of 2G systems, not often well publicized, are: * In less populous areas, the weaker digital signal will not be sufficient to reach a cell tower. * Analog has a smooth decay curve, digital a jagged steppy one. This can be both an advantage and a disadvantage.
What is the sign of frequency?
symbol fFrequency is denoted by the symbol f, and is measured in hertz (Hz) – formerly called cycles per second (cps or c/s) – kilohertz (kHz), or megahertz (mHz).
What is reuse distance?
Reuse distance is the number of distinct memory references that have happened between two memory refer- ences to the same location. In short, it tells you when was the last time you used this address.
