The management of cell phone jammer can be implemented by sections

Or some of the busiest section of the district traffic and TCH channel is not enough to produce the Assignment Falure (TCH assignment failure) by the TCH congestion. These are TMSC1 not received the news of the end office to send back the ANC (ANN). So, long distance, then switch rate is a very comprehensive assessment indicators, can scientifically measure the overall quality of the GSM network. Paging success rate and long distance, then switch rate are closely related. The general said the level of the Paging success rate and long distance, then switch rate the level of the corresponding relations. Wireless coverage, the base station simply Paging less than a cell phone; if SDCCH congestion, the phone grab less than a dedicated channel to the hair to the base station on the Paging the Response.The control of  cell phone jammer  is performed by buildings
In addition to the individual hot spots, for the time being can basically meet the need. Zhejiang Telecom GSM 5, expansion of the GSM network frequency range: 898.6 ~ 908.8MHz, a total of 10.2MHz. A network band extends to 885.0125MHz GSM network bands down extended to 14.4MHz 23 to 94 frequency points in the six expansion principle. At present, Zhejiang Telecom G base stations in many areas has been very intensive, particularly the three cities of Hangzhou, Ningbo and Wenzhou, part of the distance between the base station is only four or five meters, the selection of suitable sites for has become increasingly difficult. Stand too close, resulting in the same frequency and adjacent channel interference increases. In addition, the higher the antenna gain, the narrower its beamwidth in the vertical plane.The management of  cell phone jammer  can be implemented by sections
RF frequency hopping, power control, continuous emission, antenna diversity techniques, in order to reduce interference; without changing existing network infrastructure. However, despite the high utilization of this approach frequency, but the system interference increases, such as using anti-jamming measures are not effective and may have a greater impact on network quality and should therefore be used with caution. Concentric circles technique is usually the district is divided into the outer layer (Overlay) and inner (underlay), the outer layer of coverage for traditional honeycomb cell, while the inner layer of the coverage is mainly concentrated near the base station. In addition, the inner and outer layers of the frequency reuse coefficient is generally different from the outer layer of the general 4 × 3 reuse, while the inner layer closer to reuse, such as 3 × 3,2 × 3 or 1 × 3, etc. .  cell phone jammer  can be used for 24 hours 365 days continuously.
Depending on the implementation of concentric circles can be divided into ordinary concentric circles with the smart two kinds of double-layer network (IUO), the main difference between the two is that the transmit power of inner and outer layers of the inner switching algorithm.
