  • Method and system for extending multiple input multiple output wireless service
    Patent number: 8880082
    Abstract: Disclosed herein is a method and system for extending MIMO service in a wireless communications system. The system comprises a base station, a remote system, and a host system communicatively coupled to the base station and the remote system. The base station is configured to generate, from a baseband signal, a downlink signal comprising a plurality of downlink signal streams, including at least a first downlink signal stream and a second downlink signal stream. Accordingly, the base station may include a first and a second antenna that are configured to transmit the first and second downlink signal streams, respectively. The remote system provides wireless service in a remote coverage area. Further, the remote system is configured to transmit a downlink signal as a plurality of downlink signal streams. The host system is communicatively coupled to the base station and to the remote system and configured to relay the downlink signal streams from the base station to the remote system.
