1. A wireless communication system distributed over a plurality of floors of an infrastructure having a coverage area, comprising:
a plurality of remote units, each of the plurality of remote units comprising:
at least one electrical-to-optical (E/O) converter configured to convert electrical uplink communications to optical uplink communications;
at least one optical-to-electrical (O/E) converter configured to convert optical downlink communications to electrical downlink communications; and
at least one antenna configured to transmit radio frequency (RF) communications services to the coverage area;
wherein at least one of the plurality of remote units comprises:
a first communications port connected to and configured to provide power to a first external power-consuming device configured to provide WiFi service in the coverage area; and
a second communications port;
a head end comprising a remote controller coupled to the plurality of remote units, wherein the remote controller is configured to provide a prioritization of services;
at least one riser cable comprising a plurality of optical fibers in optical communication with the head end; and
at least one interconnect unit in optical communication with the at least one riser cable, wherein a plurality of cables connects at least two of the plurality of the remote units to the at least one interconnect unit.
