高速铁路长大涉水大桥无线覆盖方案
Research on Wireless Coverage Scheme for Long and Large Water-crossing Bridges of High Speed Railways
摘要
Abstract
The wireless coverage of long and large water-crossing bridges of high speed railways is a difficulty in wireless communication design and construction.Due to water surface distance,water surface reflection and other restraint factors,the high tower is generally set on land for wireless coverage.Additionally,the repeaters and supporting rods are set on the bridge deck,and the leaky cable or antennas are used for coverage.This paper studies the field strength coverage and quality test data of various schemes,identifies the advantages and disadvantages of each scheme,and conducts a comparative analysis.In actual projects,it is necessary to consider the actual situation of the bridges,and choose an economical,reasonable and feasible scheme.关键词
