Abstract: A communication system includes master host unit, hybrid expansion unit, and remote antenna unit. Master host unit communicates analog signals with service provider interfaces. Master host unit and hybrid expansion unit communicate N-bit words of digitized spectrum over communication link. Hybrid expansion unit converts between N-bit words and analog spectrum. Hybrid expansion unit and remote antenna unit communicate analog spectrum over analog communication medium. Remote antenna unit transmits and receives wireless signals over air interfaces. Master host unit includes master clock distribution unit that generates digital master reference clock signal. Master host unit communicates digital master reference clock signal over communication link. Hybrid expansion unit receives digital master reference clock signal from master host unit over communication link and generates analog reference clock signal based on digital master reference clock signal. Hybrid expansion unit sends, and remote antenna unit receives, analog reference clock signal across analog communication medium.

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).

Abstract: A distributed antenna system includes a host unit configured to receive downlink wireless network information from a radio access network interface and at least one antenna unit communicatively coupled to the host unit by at least one digital communication link. Host unit is configured to convert downlink wireless network information received from radio access network interface from first protocol layer to second protocol layer. Second protocol layer uses relevant bits more efficiently than first protocol layer. Host unit is configured to communicate downlink wireless network information to at least one antenna unit across at least one digital communication link. At least one antenna unit is configured to convert downlink wireless network information communicated from host unit from second protocol layer to downlink radio frequency signals. At least one antenna unit is configured to communicate downlink radio frequency signals wirelessly using at least one antenna.

Abstract: Embodiments described herein relate to a host unit for a distributed antenna system. The host unit includes a first radio access network (RAN) interface module to communicate with a RAN node. The host unit also includes a distribution module configured to distribute transport signals between one or more downstream RJ45 connectors and the first RAN interface module. One or more non-permanent connectors are included to couple the distribution module to a second RAN interface module and one or more upstream RJ45 jacks. The one or more upstream RJ45 jacks are configured to pass Ethernet signals therethrough. The distribution module is configured to couple a downlink portion of the first transport signals and either a downlink portion of the second transport signals or a downlink Ethernet signal from one of the upstream RJ45 jacks to a first twisted pair cable connected to one of one or more downstream RJ45 jacks.
