  • Patent number: 10545308
    Abstract: A flat drop cable has notches or other structures for enhancing the stripability of the jacket from the a core of the flat drop cable. The notches can have an angled configuration with surfaces that converge as the notch extends into the jacket. Inner edges of the notches can be positioned along a tear path that intersects the core of the flat drop cable. For example, the notches can be offset from a minor axis of the flat drop cable a sufficient distance such that the notches are positioned outside a central boundary region that extends tangent to sides of the core and parallel to the minor axis of the flat drop cable.

  • Patent number: 10539651
    Abstract: Embodiments described herein provide for a method for obtaining location information regarding a wireless unit in a distributed antenna system (DAS). The method includes identifying a first time of arrival of a wireless signal in a time and frequency unit at a first active antenna unit (AAU). A second time of arrival of the wireless signal in the time and frequency unit at a second AAU is also identified. A location of a wireless unit transmitting the wireless signal is estimated based on a location of the first AAU, a location of the second AAU, and a difference between the first time of arrival and the second time of arrival. The location of the wireless unit and an indication that the location corresponds to the time and frequency unit is sent to a baseband unit or serving mobile location center (SMLC).

  • Patent number: 10536915
    Abstract: Certain features relate to compensating for a roundtrip delay caused by a distributed antenna system. A delay unit communicatively coupled to a base station can intercept the delay compensation signaling communicated between the digital baseband unit of the base station and the radio transmitter unit of the base station. The delay unit can adjust the delay compensation signaling by adding to the delay compensation signaling the pre-determined fiber delay caused by the DAS. In some aspects, the delay unit can delay the control words for a base station operating under the Common Public Radio Interface standard. In other aspects, the delay unit can delay the round-trip time measurement message for a base station operating under the Open Base Station Architecture Initiative standard.
