Ensure that all base stations in the network run the normal antenna and feeding system can run well. 38 of Hebei Engineering College 3.1 base station antenna system operation index optimization method for optimizing the network to lay a solid and reliable basis, the author sums up the base station antenna of the following methods to optimize the system. 1) antenna system on the electrical properties of the test to ensure that the base station transmitting and receiving signals properly. 2) Antenna installation fees by check, to ensure that the specification of the system installed to eliminate risks of failure. 3) Check the grounding system for lightning protection to ensure that antenna systems,<a href="http://www.toryburchsaler.net" target="_blank">tory burch</a>, base stations and transmission tower, a good grounding performance. 4) The erection of the antenna azimuth angle, pitch angle adjustments to improve network coverage and better interference conditions. 5) The selection of antenna, base station sites, stations and other project-based inspection and planning to improve network coverage condition, give full play to network resources, save construction and operation and maintenance costs. 6) establish a comprehensive database base file for future network construction, operation and maintenance to provide reliable and effective basis. 7) through the optimization of the antenna system, not only to higher level network optimization for the foundation, but also help to improve the reliability of network operation, the gold medal is more conducive to creating the network and attract more users to join. 3.2 Contrast wireless environmental monitoring, a reasonable construction of the antenna network in the initial selection because of the smaller users, the general regional system of base stations, the use of high towers to increase coverage. But after a few of the expansion, especially after higher density urban base stations, antennas need to be re-optimized, in particular, the height of the antenna should be dropped, otherwise the number of base stations would cause interference to the surrounding, but also result in more area coverage, handover success rate decreased rate of dropped calls increased and so on. In addition, many in the erection of the antenna, due to the establishment of post billboards around the production of new buildings, causing part of the sector should be difficult to absorb the traffic, although in the high traffic area, but traffic is very low. By re-adjust the antenna position,<a href="http://www.stivaliuggboots.com" target="_blank">ugg milano</a>, select the appropriate antenna depending on the location model, to ensure reasonable coverage of the antenna in order to ease the traffic load around the district to ensure the full and rational use of radio resources. 4 Conclusion of the above analysis, in order to fundamentally solve the Antenna problems, from routine maintenance on equipment, manpower, Antenna regular inspection, testing, identify problems and timely treatment. The maintenance and installation personnel to enhance their own quality training, master Antenna installation and maintenance methods, use of the rich to maintain means of quickly and accurately diagnose and troubleshoot problems, improve maintenance efficiency and ensure quality of mobile network operations.
