Total emission power of cell phone jammer is about 1.2W

Often there are some serious adjacent channel, coupled with the physical environment and terrain change, we must fine-tuning must be in their daily work by measuring to be modified and adjusted, in order to further reduce interference, the optimum frequency of the program . Frequency planning that can not be used in many frequency points, but can be used in the implementation; frequency that can be used in planning, implementation, there may be a serious interference because of the terrain height, reflection, and other reasons. In addition, the terrain caused by the phenomenon of cross-regional coverage, especially these station antenna is often because of objective reasons can not be lower in more detail the frequency of adjustment, which must rely on to solve. In practice, we adjusted for part of the cell frequency, the interference problem significantly improved. This kind of cell phone jammer has little influence on cell phone or other electronic equipment.
But this is a repeated need to constantly be adjusted to achieve the best results. Good frequency planning is to achieve a good switching performance, especially the more important is the planning of BCCH. If done well, it will lead to the MS in decoding the BSIC spend more time due to poor quality, so that the switch has become very slow, or no solution BSIC lead to dropped calls. BSIC planning is very important. BSIC = NCC + BCC, in which the TSC = the BCC, NCC and BCC, respectively, from 0 to 7. BSIC code of 0 to 63 in decimal, for example. Generally a station allocated a BSIC code, but can also be a station within the different communities with different BSIC code. Total emission power of cell phone jammer is about 1.2W.
Balanced traffic generally have the following methods: expansion, ie to solve the congestion by increasing the channel of the high traffic district; the construction of micro-cellular, in practice, we think this is one of the best, most effective way; to adjust the antenna direction through high-traffic areas, to achieve the purpose of sharing traffic, so that the boundary of two or more cells, but it will bring a lot of switching, increase the system load; parameter adjustment, OFFSET, CRO and other relevant parameters to artificially interfere with or encourage the mobile station to enter in some quarters. In practice, depending on the circumstances, to choose the best method. Compared with the macrocell, micro-cellular has the following characteristics: the coverage of small (typically a few hundred meters), install, easy to use. The customer can select this kind of  cell phone jammer as the practical tool.
