1. A wireless communication system comprising:
a multilevel facility comprising a concrete floor structure that separates a first floor of the multilevel facility from a second floor of the multilevel facility, wherein a lower surface of the concrete floor structure forms a ceiling of the first floor, and an upper surface of the concrete floor structure forms a floor of the second floor;
a plurality of container carrying assemblies disposed on the floor of the second floor, wherein individual container carrying assemblies of the plurality of container carrying assemblies comprise a metal structure and are configured to support a plurality of containers having objects disposed therein;
an autonomous mobile robot configured to transport the individual container carrying assemblies from a first location to a second location on the floor of the second floor;
a first wireless access point coupled to the lower surface of the concrete floor structure, such that the first wireless access point is positioned in the first floor of the multilevel facility, wherein the autonomous mobile robot is configured to wirelessly communicate with a remote computer system via the first wireless access point;
a first antenna embedded in the upper surface of the concrete floor structure, such that the first antenna is positioned in the second floor of the multilevel facility, the first antenna coupled to the first wireless access point and configured to transmit and receive wireless data, wherein the first antenna is a round antenna; and
a first antenna cable coupled to the first wireless access point and the first antenna, wherein the first antenna cable passes through the concrete floor structure.
