Multiple-TRX pico base station for providing improved wireless capacity and coverage in a building

A pico base station system comprising:

• a pico base station that includes:
• an enclosure;
• a plurality of radio transceivers, housed within the enclosure, to transmit and receive, within a building, wireless traffic using radio frequency spectrum assigned to a at least one public land mobile network;
• and
• an interface to communicatively couple the plurality of radio transceivers to the at least one public land mobile network using an Internet Protocol (IP) backhaul connection for which voice signals are converted to IP packets;
• wherein the pico base station is configured so that to output the wireless traffic is output by the pico base station at a power level less than one Watt;
• wherein the pico base station is coupled to a distributed antenna system used to couple the pico base station to a plurality of antennas;
• and
• wherein the a distributed antenna system comprises including a hub unit installed within a rack included in a server room and a plurality of remote antenna units located within a the building, wherein the hub unit is a separate component than the pico base station, wherein the remote antenna units are located remotely from the hub unit and each of the plurality of antennas is coupled to at least one of the plurality of remote antenna units, wherein each radio transceiver of the plurality of radio transceivers of the pico base station is configured to be coupled to a hub unit of the distributed antenna system used to couple the pico base station to a plurality of antennas;
• wherein the hub unit includes one or more converters configured to convert the wireless traffic output by the pico base station to a first form, wherein each of the remote antenna units includes one or more converters configured to convert the wireless traffic from the first form to a second form, wherein the wireless traffic is radiated from the antennas in the second form.
