Power distribution module(s) for distributed antenna systems, and related power units, components, systems, and methods
First Claim
1. A distributed antenna system, comprising:
- a power distribution module comprising;
a power supply configured to provide a plurality of power outputs; and
a plurality of power controllers each connected to a respective one of the plurality of power outputs in parallel to provide split power from the power supply to a respective power controller output;
each power controller output coupled to a respective power output port, at least two power output ports configured to be coupled to a single remote unit in a first connection configuration and each power controller output configured to be coupled to a respective remote unit in a second configuration; and
a remote unit comprising;
a first power input configured to receive a first power signal from a power distribution module through a first power medium;
a second power input electrically isolated from the first power input, the second power input configured to receive a second power signal from the power distribution module through a second power medium;
a communications module configured to receive power from at least one of the first power input and the second power input to communicate radio frequency (RF) communications with client devices through an antenna defining an antenna coverage area associated with the remote unit; and
at least one wired service port configured to couple to at least one of the first power input and the second power input to distribute power to an external module coupled to the at least one wired service port.

Abstract
A power distribution module can be installed in and connected to a power unit for providing power to a power-consuming DAS component(s), such as a remote unit(s) (RU(s)) as a non-limiting example. The RU may include an antenna, and may sometimes be referred to as a remote antenna unit or RAU. Power from the power distribution module is distributed to any power-consuming DAS components connected to the power distribution modules including but not limited to remote units. The power distribution modules distribute power to the power-consuming DAS components to provide power for power-consuming components in the power-consuming DAS components. In a first configuration, the power distribution module uses two power links to provide power to a single RU. In a second configuration, the power distribution module uses two power links to provide power to two RUs.
