Abstract: A signal interface unit for interfacing uplink downstream signals from a downstream device with an upstream device includes at least one upstream interface configured to communicate a primary uplink upstream signal and at least one emulated-diversity uplink upstream signal to an upstream device; a downstream interface configured to receive an uplink downstream signal from a downstream device; wherein the signal interface unit is configured to convert the uplink downstream signal into the primary uplink upstream signal; wherein the signal interface unit is further configured to generate the at least one emulated-diversity uplink upstream signal from at least one of the primary uplink upstream signal and the uplink downstream signal.

Abstract: Clock Priority Chain Level Systems and Methods are provided. In one embodiment, a method for determining clock priority for a multihost unit distributed antenna system is provided. The method comprises identifying which port of a plurality of ports is receiving a reference clock signal having a highest priority Network Chain Level (NCL) value, wherein the highest priority NCL value indicates a master clock priority level (MCPL) of a host unit providing a Master Clock and a chain level value indicating a chain depth; selecting a system clock reference port from the plurality of ports based on the highest priority NCL value; locking a local clock to a reference clock signal received on the selected system clock reference port; calculating an incremented NCL value based on the highest priority NCL value; and transmitting the incremented NCL value over the plurality of ports.

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.
