cell phone jammer in the specific area in the workshop

CDMA network distribution system is mainly used to solve the high-rise pilot pollution problems: pilot pollution is a guide when the cell phone received four or more Ec / Io the intensity is greater than T_add frequency, and which do not have a pilot the intensity can be used as when the dominant frequency. The object of low heat resistance should keep away from  cell phone jammer .
Pilot pollution in the pilot Ec / Io is poor in contaminated areas inside and not stop the signal of cell phone Idle transformation caused by cell phone from respiratory difficulties; cell phone if the call state, a pilot suddenly become strong and it is not the mobile station effective set, then the cell phone will be dropped calls.
Test report submitted in addition to detailed to reflect the call problem areas, the structure of the overall framework of the building wall to outline in detail the link budget to provide sufficient conditions for signal recording. Should be more simple, clear, the report should also include the pilot number of each pilot field strength Ec / Io, this information is very important. Network optimization is a key link in the network construction and development. In the course of the CDMA network optimization, pilot pollution is a need to focus on resolving the problem, the results of a direct impact on the improvement of network performance.
Base station after the opening test, so that the coverage of base stations to achieve we have to control the range, and will not have coverage, covering issues such as weak or senior pilot pollution. Pay attention to the maintenance of each base station in the existing network to ensure that each base station can run well. Coverage is very important in the choice of antenna type, to be adapted to local conditions, and flexible use. General can be considered to select the ESC or the built-in inclination in the urban areas, with the upper side lobe rejection, vertical lobe of the antenna can not be too high. Machine tune the pitch angle of the antenna can not be under pressure in the urban area is too large, greater than 8 ° lobe began to produce deformation of the concave, but has little effect; greater than 15 ° lobe concave is very powerful. the direction of the main lobe energy is almost as far as possible, generally in use can not be greater than 10 ° greater than 10 ° is necessary to use the built-in antenna of inclination or the power transfer.
