本人四川的,一外行,是搞房屋建筑工程的。最近我家所在楼栋(18层)的屋面被安装上了天线,到处钻些洞,搞破坏。问物管也说不出过所以然,说什么加强信号覆盖。哎,不管事的没用的物管。后又听说本来是准备安装到隔壁小区的,但那些业主不同意就安在咱们这个小区了,可叹物管连个公示公告都舍不得出一张。
我最初以为是加强电梯信号的,但一想不对啊,电梯旁边就是通信电缆井,为什么还要在楼顶安天线呢。于是特地到屋顶看了一圈,天线产品铭牌是烽火科技900M双极化基站天线,屋顶四大角都有安装,直接用角钢固定于女儿墙上,高度离屋顶约2.5~3m左右。通过已布置的电缆发现从屋顶上有好几根5CM粗的电缆沿外墙窗洞引入到了顶楼一住户内,估计是机房。单元电气井内有约1.5CM粗的电缆,并在每层留了一个“10db腔体[size=2]耦合器[/size]”,好像一直通到地面的电缆沟内(那天出门看到一个工作在电缆沟内工作,问那工人是安的是啥东西,工人说不知道,只管干活)。由于我这个工程在外地,一周多没回家了,听家里人说大家门口旁边安了一个什么东西,外壳上没写得有字,所以不知道是啥。每层楼安了2处。这一看更不对了吧,如果是加强电梯信号不应该安在我家门口呀。
如果只为加强电梯间信号,在电梯机房处安个天线什么的往电梯井内定向发射不就得了?无线路由那定向天线也能穿二三壁墙。当然,这是想象,毕竟不专业。
所以,现在想问一大家:
1、估计这个基站是干什么用的?
2、此类基站建设是否也像大家建筑工程一样,有设计、施工、监理、验收等建设程序,以及其它行政审批程序?
3、此基站天线安装是否符合要求,对人体有没有影响?
4、有没有相关行业规范、规定,叫什么名字?
谢谢!

这个应该叫做室内分布。增强手机信号用的,如果不安装的话,住户和楼梯间可能信号很弱,甚至完全没信号,这也是运营商为了更好的提供服务做的。
楼主完全不用担心,大家就是干这的,这都是经过设计院设计,监理企业监理,专业施工队施工完成的,有它一整套的工作流程。室分天线出口功率一般是10dBm左右,手机发射5-33dBm。室分天线一般离人体较远(几米之外),手机一般是紧贴在头部使用,所以手机的辐射要比室分天线大多了。所以挂的这个天线比您口袋里的手机要安全!
