1. A system for transporting wireless communications, comprising:
a set of digital access units (DAUs) that receive a set of radio resources from one or more signal sources including:
a first DAU that provides a first subset of the set of radio resources, and
a second DAU that is communicatively coupled to the first DAU and provides a second subset of the set of radio resources; and
two or more remote units, including:
a first remote unit that is communicatively coupled to the first DAU and includes a first antenna for transmitting the first subset of the set of radio resources, wherein the first remote unit is included in a first set of remote units, and the remote units in the first set of remote units are daisy-chained such that each remote unit is linked to a next remote unit by a single bi-directional optical fiber, and
a second remote unit that is communicatively coupled to the second DAU and includes a second antenna for transmitting the second subset of the set of radio resources,
wherein a first number of radio resources in the first subset is different than a second number of radio resources in the second subset.
