What is frequency reuse in GSM?
Frequency Reuse 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. Frequency reuse offers the following benefits − Allows communications within cell on a given frequency.
What is it 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.
How do you find the frequency reuse ratio?
The number of cells after which a frequency channel can be reused is called as the Frequency reuse factor (R.F). It is given by R. F=1/N, Where N is the cluster size.
What is frequency reuse and cluster?
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.
What is the frequency reuse factor in CDMA?
Figure 1.10 shows how CDMA systems can reuse the same frequency in each cell site. This example shows that the frequency use factor is 1 (N=1) and that the overlap of the radio channels results in an increased interference level in the overlapping area.
Which is the disadvantage of frequency reuse?
Although frequency reuse- m model mitigates ICI, the main disadvantage of such technique is that it reduces network capacity. With less resources available in each cell, the operator is not able to accommodate all the existing UEs.
What are GSM standards?
The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.
Why GSM is better than CDMA?
GSM users can experience better voice quality than CDMA users or vice versa in particular areas. Furthermore, the GSM network can transmit voice and data simultaneously. On the other hand, not all CDMA phones can transmit voice and data at the same time.
What are the disadvantages of Sectoring?
Disadvantages of cell sectoring :
- Increases number of antennas per base station.
- A decrease in trunk efficiency.
- Loss of traffic.
- Increased number of handoffs.
