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.

Cellular Concept”— Presentation transcript: Basics – Early mobile telephony systems were not cellular.

Wireless & Mobile Networking: Cellular Concept

Clusters A cluster is a group of cells. More channels become available to users that appear in the saturated region based on demand and economic consideration As a service area becomes full of users, this approach is used to split a single area into smaller ones. 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.

Difference crll co-channel interference and adjacent channel interference. These Days Then, cellular system replaced a large zone with a number of smaller cells, with as single BS covering a fraction of the area. Difference between GTO and thyristor. 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 esctoring set of frequencies.

Cell Splitting and Sectoring by Agnidhra Ghosh on Prezi

PIN diode are very good for RF switching, and pho Number of channels per system a. Definition A cellular mobile communication system uses a large number of low-power wireless transmitters to create cells- the basic celp service area of a wireless communications system.

Frequency Reuse -Because only a small number of radio channel frequencies were available for mobile systems, engineers had to find a way to reuse radio channels to carry more than one conversation at a time. Zigbee is the wireless language that every devices use to co The increase in demand could not be satisfied just by additional spectrum allocations.

A hex pattern is the simplest pattern that can translate into an area. That resulted in very low capacity. Interference is the main problem in increasing capacity. The area of overlap, area C, has a frequency conflict and interference.

The ability of the system to carry many signals at the same time is called channel access. Capacity can be increased by additional partitions. Published by Modified over 3 years ago. Cells 2 The most important factor in cellular system is the size and the shape of cell.

Advantages and disadvantages of PIN diode. The performance of the cellular system is highly affected by interference. Elevation of the terrain Presence of a hill or tall building Presence of particles in the air.

For convenience, the cells are shown with a hex pattern. Advantages and disadvantages of SDMA.

The solution the industry adopted was called frequency planning or frequency reuse. Factors that cause reflections and refractions of the signal: The coverage area of cells is called the footprint.

PIN diode is used in a variety of different application from low to high radio frequency. A hexagonal cell is one of the Interference resulting from two or more simultaneous transmissions on the same channel.
