What is Sectoring in cellular communication?

What is Sectoring in cellular communication?

Cell sectoring is used to increase the cellular system capacity through reducing the co-channel interference. Traditional sectoring is fixed sectoring with 3 or 6 sectors and identical sector size. It is efficient to mitigate the interference in case of uniform traffic in a cell.

What is cell splitting and Sectoring?

Cell splitting is a method of subdividing cell into the smaller sized cell. The parent cell that was originally congested is called as macro cells and the smaller cell called as microcells. Cell sectoring is another method to increase capacity.

What do you understand by Sectoring explain?

The technique for decreasing co-channel interference and thus increasing system performance by using directional antennas is called sectoring. The factor by which the co-channel interference is reduced depends on the amount of sectoring used. A cell is normally partitioned into three sectors.

What are the benefits of using Sectoring in cell design?

Advantages of cell sectoring : Reduces interference. Increases capacity. Reduces cluster size. More freedom in assigning channel.

What is cell Sectoring and why is it used in wireless communication?

Cell sectoring is a method of decreasing the co-channel interference and enhancing system performance by using a directional antenna. The size of clusters in a particular service area can be reduced because the cell sectoring increases the signal to interference ratio (SIR).

How cell Sectoring improves the capacity of cellular system?

The number of cells in a specific cluster is decreased in cell sectoring, and the separation between co-channels is decreased. So, cell sectoring basically refers to the method of decreasing co-channel interference to increase the cellular system capacity by using directional antennas for each sector within a cell.

Why is cell splitting and Sectoring important in cellular telephony?

While the purpose of both cell splitting and cell sectoring is same –to increase the channel capacity and improve the reliability of a cellular telephone network – they work very differently.

How does Sectoring achieve cellular system capacity improvement?

B) SECTORING: This is another method to increase cellular capacity and coverage by keeping cell radius unchanged and decreasing D/R ratio. In this approach, capacity improvement is achieved by reducing the number of cells in a cluster and thus increasing the frequency reuse.

How does Sectoring increase capacity?

How cell splitting and Sectoring techniques improves the capacity of cellular system?

It 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 increase the capacity of the cellular system since it increases the number of times that channels are reused.

How does cell Sectoring reduce co-channel interference?

Summary of Cell Splitting and Cell Sectoring Cell sectoring, on the other hand, reduces co-channel interference by reducing the number of interferers that each cell is exposed to, whereby each cell is divided into radial sectors with directional BS antennas.

What is frequency reuse cell Sectoring and cell splitting in mobile communication?

Techniques such as cell splitting, sectoring, and coverage zone approaches are used in practice to expand the capacity of cellular systems. Cell splitting allows an orderly growth of the cellular system. Sectoring uses directional antennas to further control the interference and frequency reuse of channels.

What are co-channel cells?

The group of cells where the available frequency spectrum is totally consumed is called a cluster of cells. Two cells having the same number in the adjacent cluster, use the same set of RF channels and hence are termed as “Co-channel cells”.

How does Sectoring reduce interference?

ABSTRACT : In this work, cell sectoring is used to reduce cochannel interference in the reverse link of a wireless cellular network. The advantage that the number of interfering mobiles decreases with respect to the increase in the number of sectors is taken to sectorize a cell with 120 degrees opening per sector.

How does cell Sectoring expand capacity?

What is the principle of 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. For example, when N cells are using the same number of frequencies and K be the total number of frequencies used in systems.

What do you mean by co-channel?

/ (ˈkəʊˌtʃænəl) / adjective. denoting or relating to a radio transmission that is on the same frequency channel as anotherco-channel interference.

What is co-channel in mobile communication?

What is co-channel in wireless communication?

Co-channel interference takes place when two access points within a network are on the same channel, causing interference that weakens the signal and thus provides problems to the end-user experience on the network.
