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.
Changing physical radio channels of network connections involved in a call. Cellular Eric Anderson Fall www. Cells 2 The most important factor in cellular system is the size and the shape of cell.
Neighboring splittung stations BS are assigned different sets of channels. What is the number of channels per cell? Difference between GTO and thyristor. Selecting this threshold level is critical to 1 ensure unnecessary handoffs do not occur; and 2 call eplitting does not splittingg. About project SlidePlayer Terms of Service. A hex pattern is the simplest pattern that can translate into an area. Government regulations that make specific ranges of. My presentations Profile Feedback Log out.
The parent cell that was originally congested is called as macro cells and the smaller cell called as microcells. Fiber optic cable color code. Cell sectoring is a method of decreasing the co-channel interference and enhancing the system performance by using directional antenna. The parent cell that was originally congested is called as mac Share buttons are a little bit lower.
Zigbee is a wireless protocol used for wireless networking and connectivity. Advantages and disadvantages of SDMA. Since a given channel is active only in a particular zone in which mobile is traveling, base station radiation is localized and interference is reduced. Ideally, wectoring should be in circular shape. For convenience, the cells are cdll with a hex pattern. Interference resulting from two or more simultaneous transmissions on the same channel.
We think you have liked this presentation. Capacity can be increased by additional partitions. To make this website work, we log user data and share it with processors. This footprint is limited by a boundary so that the same group of channels can be used in different cells that are far enough sectoringg from each splutting so that their frequencies do not interfere -Cells with the same number have the same set of frequencies.
Advantages and disadvantages of Zigbee networks. The solution the industry adopted was called frequency planning or frequency reuse. Zigbee is the wireless language that every devices use to co Difference between cell splitting and cell sectoring.
Let we check the difference between cell splitting and cell sectoring: That resulted in very low capacity. 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.
7 Difference Between Cell Splitting And Cell Sectoring
Methods for improving coverage area in cellular systems Cell Splitting: 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. An example of cell splitting is shown below the base station are placed in corners of the cells, and area served by base station A is assumed to be saturated with traffic. New base stations are therefore needed in the region to increases the number of channels in the area and to reduce the area served by the single base station. Sectoring increases SIR, so that the cluster size may be reduced. First the SIR is improved using directional antennas, then capacity improvement is achieved by reducing the number of cell in the cluster; thus increasing the frequency reuse. To achieve this, it is necessary to reduce the relative interference without decreasing the transmit power.
