Abstract: An antenna unit includes a first physical layer processor configured to receive a first downlink physical layer signal from an upstream device and to convert first downlink physical layer signal into first downlink higher layer data units; a higher layer processor configured to convert first downlink higher layer data units into second downlink higher layer data units; a second physical layer processor configured to generate a second downlink physical layer signal from second downlink higher layer data units; and a radio frequency conversion module configured to convert second downlink physical layer signal into radio frequency signals for communication using an antenna. Communication between upstream device and antenna unit using first downlink physical layer signal having first downlink higher layer data units has a lower data rate than would communication between upstream device and antenna unit using second downlink physical layer signal having second downlink higher layer data units.

Abstract: A distributed base station radio system includes first channelized to broadband conversion unit that receives first downlink channelized data for first radio frequency band from first channelized radio frequency source; and first universal remote radio head communicatively coupled to first channelized to broadband conversion unit. First channelized to broadband conversion unit converts first downlink channelized data into a first downlink broadband signal. First channelized to broadband conversion unit communicates the first downlink broadband signal to first universal remote radio head. First universal remote radio head receives first downlink broadband signal. First universal remote radio head frequency converts the first downlink broadband signal into first downlink radio frequency signals in first radio frequency band. First universal remote radio head is further configured to transmit first downlink radio frequency signals in first radio frequency band to first subscriber unit.

Abstract: A distributed antenna system includes a host unit communicatively coupled to a first service provider interface which receives a first signal from the first service provider interface; and a first remote antenna unit communicatively coupled to the host unit, the first remote antenna unit having a first antenna. A base station to which the distributed antenna system is communicatively coupled is configured with a subscriber access timing window having a minimum allowed delay and a maximum allowed delay. The distributed antenna system is configured so that a first total delay between the host unit and the first remote antenna unit is equal to or greater than the minimum allowed delay. The first antenna of the first remote antenna unit is configured to communicate the first signal to a first subscriber unit.

Abstract: Embodiments described herein provide for a distributed antenna system including a host unit and an active antenna unit (AAU). The AAU is configured to wirelessly communicate with, and to receive uplink radio frequency (RF) signals from, one or more wireless devices. The AAU is further configured to sample the uplink RF signals to generate digitized RF data. The AAU includes an Ethernet interface for receiving Internet Protocol (IP) formatted data from an IP device coupled to the Ethernet interface. The AAU is configured to transport the digitized RF data and the IP formatted data over a transport signal to the host unit, the transport signal including a plurality of bits. The AAU is configured to adaptively adjust the number of bits that are allocated to the digitized RF data and the number of bits that are allocated to the IP formatted data.

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).
