CELL SPLITTING AND CELL SECTORING PDF

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. Cell splitting is the technique of dividing a larger cell into smaller cells to increase capacity in What is the difference between cell splitting and cell sectoring?. Sectoring. cell splitting keeps D / R unchanged (same cluster size and CCI) but increases frequency reuse/area; alternate way to ↑ capacity is to _____ CCI.

This footprint is limited by a boundary so that the same group of channels can be used in different cells that are far enough away from each other so that their frequencies do not interfere -Cells with the same number have the same set of frequencies.

Popular Posts Difference between cell splitting and cell sectoring. Cell sectoring is a method of decreasing the co-channel interference and enhancing the system performance by using directional antenna.

Changing physical radio channels of network connections involved in a call. The increase in demand could not be satisfied just by additional spectrum allocations.

In practice, cells are not hexagonal and BS are not exactly in the center of the cell. Share buttons are a little bit lower. Newer Post Older Post Home. Capacity can be increased by sectorimg partitions. Cellular Concept”— Presentation transcript: Interference is the main problem in increasing capacity.

No channels splittibg reused within a cluster.

If you wish to download it, please recommend it to your friends in any social system. Neighboring base stations BS are assigned different sets of channels. The ability of the system to carry many signals at the same time is called channel access. Factors that cause reflections and refractions of the signal: Registration Forgot your password?

Zigbee is the wireless language that every devices use to co Let we check the difference between cell splitting and spliyting sectoring: Handoff Handoff is the process of transferring a call from one base station to another when a user’s radio signal becomes weaker at the first and stronger at the second base station. Elevation of the terrain Presence of a hill or tall building Presence of particles in the air. Development of highly reliable. Number of channels per system a. Advantages and disadvantages of Zigbee networks.

We think you have liked this presentation. The area of overlap, area C, has a frequency conflict and interference. Ideally, cell should be in circular shape. Advantages and disadvantages of power electronic converters. The solution the industry adopted was called frequency planning or frequency reuse. Basics – Early mobile telephony systems were not cellular.

If you look at the base of the tower, you can see that each provider xell its own equipment, and you can also see how little equipment is involved today older towers often have small buildings at the base.

Difference between GTO and thyristor.

Wireless & Mobile Networking: Cellular Concept

Cell sectoring decreases the coverage area of a group of channels and increases the number of handoffs. Figure 1 illustrates a seven-cell cluster.

Cells 2 The most important factor in cellular system is the splittign and the shape of cell. These N cells are said to form a cluster. What is channel access? Since a given nad is active only in a particular zone in which mobile is traveling, base station radiation is localized and interference is reduced.

Frequency reuse was not employed. The parent cell that was originally congested is called as mac That resulted in very low capacity. Cellular Telephone Networks By: The mobile retains the same channel and the base station simply switches the channel to a different zone site and the mobile moves from zone to zone.
