    • Embodiments disclosed provide sectorization in distributed antenna systems, and related components and methods. The antenna units in the distributed antenna systems can be sectorized. In this regard, one or more radio bands distributed by the distributed antenna systems can be allocated to one or more sectors. The antenna units in the distributed antenna systems are also allocated to one or more sectors. In this manner, only radio frequency (RF) communications signals in the radio band(s) allocated to given sector(s) are distributed the antenna unit allocated to the same sector(s). The bandwidth capacity of the antenna unit is split among the radio band(s) allocated to sector(s) allocated to the antenna unit. The sectorization of the radio band(s) and the antenna units can be configured and/or altered based on capacity needs for given radio bands in antenna coverage areas provide by the antenna units.
    • 公开的实施例提供分布式天线系统中的扇区化,以及相关的组件和方法。 分布式天线系统中的天线单元可以扇区化。 在这点上,由分布式天线系统分配的一个或多个无线频带可被分配给一个或多个扇区。 分布式天线系统中的天线单元也被分配给一个或多个扇区。 以这种方式,仅分配给给定扇区的无线电频带中的射频(RF)通信信号被分配给分配给相同扇区的天线单元。 天线单元的带宽容量在分配给分配给天线单元的扇区的无线频带之间被分离。 可以基于由天线单元提供的天线覆盖区域中的给定无线电频带的容量需求来配置和/或改变无线电频带和天线单元的扇区化。

    • Transponder systems and methods for radio-over-fiber (RoF) wireless picocellular system are disclosed. One type of transponder system includes a RoF transponder used in combination with at least one radiation-reflector assembly to provide for enhanced antenna directivity of the transponder. Another type of transponder system is a transponder node assembly, wherein two or more transponders are integrated into a single assembly, thereby reducing cost while facilitating RoF wireless picocellular system deployment. Another type of transponder system provides one or more transponders in a RoF wireless picocellular system with radio-frequency identification (RFID) tags, and uses an RFID tag reader to locate and read information from the transponders, as well as to perform transponder mode selection. Another type of transponder system is directed to a tether cable assembly that includes a dispensible/retractable coiled tether cable housed in a protective housing for connecting the tether cable to a transponder.
    • 公开了用于无线电光纤(RoF)无线微微蜂窝系统的应答器系统和方法。 一种类型的应答器系统包括与至少一个辐射 - 反射器组合组合使用的RoF应答器,以提供应答器的增强的天线方向性。 另一种类型的应答器系统是应答器节点组件,其中将两个或更多个应答器集成到单个组件中,从而在促进RoF无线微微蜂窝系统部署的同时降低成本。 另一种类型的应答器系统在具有射频识别(RFID)标签的RoF无线微微蜂窝系统中提供一个或多个转发器,并且使用RFID标签读取器来定位和读取来自应答器的信息,以及执行应答器模式选择。 另一类型的应答器系统被引导到系绳电缆组件,其包括容纳在用于将系绳电缆连接到应答器的保护壳体中的可分配/可伸缩线圈系绳。
