Abstract
A system for routing signals in a Distributed Antenna System (DAS) includes one or more local Digital Access Units (DAUs) located at a local location and one or more remote DAUs located at one or more remote locations. Each of the one or more local DAUs includes an optical port coupled to an upstream unit. The upstream unit includes at least one of a repeater, a baseband unit, a Base Transceiver Station (BTS), or a DAU. The one or more remote DAUs are coupled to the one or more local DAUs via one or more optical cables. A distance between the local location and each of the one or more remote locations is greater than two kilometers.
Claims21
A system comprising:
- one or more wireless units configured to receive a radio frequency (RF) signal from an antenna and to convert the RF signal to an optical signal;
- one or more local Digital Access Units (DAUs) located at a local location, each of the one or more local DAUs including an optical port coupled to one of the one or more wireless units via an optical cable, the optical port configured to receive the optical signal from the one or more wireless units;
- and
- one or more remote DAUs located at one or more remote locations, wherein the one or more remote DAUs include at least one port and are coupled to the one or more local DAUs via the at least one port.
A method comprising:
- receiving, via one or more wireless units a radio frequency (RF) signal from an antenna;
- converting the RF signal to an optical signal;
- receiving the optical signal from the one or more wireless units at one or more local Digital Access Units (DAUs) located at a local location, each of the one or more local DAUs including an optical port coupled to one of the one or more wireless units via an optical cable, the optical port configured to receive the optical signal from the one or more wireless units;
- and
- providing one or more remote DAUs located at one or more remote locations, wherein the one or more remote DAUs include at least one port and are coupled to the one or more local DAUs via the at least one port.
