1. A massive multiple-input multiple-output (M-MIMO) wireless distribution system (WDS), comprising:

  • a plurality of remote units each configured to be deployed at a location to serve a respective remote coverage area; and

    a central unit communicatively coupled to each of the plurality of remote units over a communications link among a plurality of communications links, the central unit being configured to;

    encode a received downlink communications signal to generate a downlink MIMO communications signal; and

    distribute the downlink MIMO communications signal over the plurality of communications links to the plurality of remote units, wherein;

    each of the plurality of remote units comprises one or more antennas configured to distribute the downlink MIMO communications signal to at least one client device located in the respective remote coverage area; and

    at least one remote unit among the plurality of remote units comprises a different number of antennas from at least one other remote unit among the plurality of remote units,wherein a location corresponding to each of the plurality of remote units is determined based on client device density distribution throughout a coverage area of the M-MIMO WDS to maximize system capacity of the M-MIMO WDS.
