Abstract

Embodiments disclosed herein include distributed antenna systems (DASs) supporting expanded, programmable communications services distribution to remote communications service sector areas. In one embodiment, the DAS includes a first programmable switch for distributing downlink communications signals into one or more communications service sector sets. The DAS further includes a second programmable switch configured to distribute the one or more communications service sector sets to one or more remote communications service sector areas. A configurable extender module is also included to provide expanded routing of communications service sector sets in the DAS. In this manner, the DAS is programmable to allow any combination of communications service sector sets and expanded communications service sector sets from any number of different base stations to be routed to any combination of remote communications service sector areas and expanded remote communications service sector areas, based on capacity needs and capability of the DAS.
