摘要
对于电信运营商来说,高站资源是一种既稀有又难以利用的资源。高站资源可以解决高层楼宇的覆盖问题,但一般的高站基站会产生较大的越区覆盖,对周边环境造成不良干扰。因此为了有效利用高站站址资源,首先对一种新型的天线——大下倾天线的性能进行了测试;然后在实际WCDMA环境中从统计角度,分析了大下倾天线在高站情况下的使用情况;最后在LTE环境下进行了路测,验证了大下倾天线的覆盖收缩能力。从实际应用的角度,证明了大下倾天线可以有效改善高站越区覆盖,盘活高站资源。
For telecom operators, high station resources are a kind of rare resource which is difficult to use. High station resources can solve the covering problem of high-rise buildings, but the high station base station generally produces larger area coverage problem, will cause harmful interference to surrounding environment. Therefore, in order to effectively use the high station site resources, a large tilt antenna was tested by using statistics data in the actual WCDMA environment. And also, road test was tested in the LTE system to prove the contractility of the antenna. From the perspective of practical application, large down tilt antenna can be used to effectively improve high station, and invigorated the high station resources.
