    • The application relates to optical fiber-based distributed antenna systems DAS or WLAN systems without a DAS infrastructure which are provided indoors, such as inside a building to provide indoor wireless communication for clients. Without such a system, wireless reception may be poor or not possible for wireless communication clients located inside the building. Other services may be negatively affected or not possible due to the indoor environment. For example, it may be desired or required to provide localization services for a client, such as emergency 911 (E911) services as an example. If the client is located indoors, techniques such as global positioning services (GPS) may not be effective at providing or determining the location of the client. Further, triangulation techniques from the outside network may not be able to determine the location of the client. This problem is solved by the application, in that the systems disclosed herein provide location information to a mobile terminal (24) via a remote unit, such as a WLAN AP (66) or a beacon terminal (78). The location information is provided within a Service Set Identifier SSID and comprises three dimensional coordinates of the remote unit. The three dimensional coordinates include the floor level. If the wireless client (24) may receive SSID signals from a plurality of APs, the client may calculate through any appropriate algorithm it's location. The wireless client (24) may include for this purpose an applet. Once calculated, the location may then be provided to other programs that can use that location, e.g., provision of E911 services or other location based services.

    • An optical fiber connector assembly (10) that provides improved radio-frequency (RF) antenna capability for a radio-frequency identification (RFID) tag (200). The assembly includes a connectorized fiber optic cable (150) having a connector (11). The assembly also includes a wire (246) that either is connected to the RFID tag or is configured to electrically connect to the RFID tag. The wire runs alongside a portion of the fiber optic cable length and is loosely held thereto. The wire serves as at least a portion of an RFID antenna (220) for the RFID tag. The RFID tag may be supported by the connector or may be supported by a connector adapter that is configured to operably engage the connector. The optical fiber connector assembly allows for improved RF antenna capability that provides improved RF communication with an RF reader (400), particularly in RFID applications where existing RFID tag antennas are inadequate. The wire can also serve as substantially the entire RFID antenna, thereby obviating the need to include an RFID antenna as part of the RFID tag.
    • 一种为射频识别(RFID)标签(200)提供改进的射频(RF)天线能力的光纤连接器组件(10)。 组件包括具有连接器(11)的连接的光纤电缆(150)。 组件还包括连接到RFID标签或被配置为电连接到RFID标签的线(246)。 电线沿着光纤电缆长度的一部分延伸并且松动地保持在其上。 该线作为RFID标签的RFID天线(220)的至少一部分。 RFID标签可以由连接器支撑,或者可被配置成可操作地接合连接器的连接器适配器来支撑。 光纤连接器组件允许改进的RF天线能力,其提供与RF读取器(400)的改进的RF通信,特别是在现有RFID标签天线不足的RFID应用中。 导线也可以充分地用作整个RFID天线,从而避免了将RFID天线作为RFID标签的一部分。
