Sectorization in distributed antenna systems, and related components and methods
First Claim
1. A method of providing RF communications signals from radio bands distributed among a plurality of sectors in a distributed antenna system, the method comprising:
- receiving in a plurality of radio interfaces, a plurality of downlink radio frequency (RF) communications signals;
in each radio interface among the plurality of radio interfaces;
providing a downlink RF communications signal among the plurality of downlink RF communications signals;
splitting the received downlink RF communications signal into a plurality of split downlink RF communications signals;
selectively switching the split plurality of downlink RF communications signals to one or more sectors among a plurality of sectors;
in each optical interface (OI) among a plurality of OIs, wherein each OI supports a subset of remote antenna units (RAUs) among a plurality of remote antenna units (RAUs);
receiving the plurality of split downlink RF communications signals from the plurality of sectors;
converting the plurality of split downlink RF communications signals into a plurality of downlink optical RF communications signals; and
selectively switching the plurality of sectors in the OI to allocate a selected one or more sectors among the plurality of sectors to the subset of RAUs supported by the OI, to provide the downlink optical RF communications signal among the plurality of split downlink optical RF communications signals selectively switched to the one or more sectors, to the subset of RAUs.

Abstract
Distributed antenna systems in which the distributed antenna systems can be sectorized. Radio bands distributed by the distributed antenna systems are allocated to one or more sectors. The antenna units in the distributed antenna systems are also allocated to one or more sectors. In this manner, only radio frequency (RF) communications signals in the radio band(s) allocated to given sector(s) are distributed the antenna unit allocated to the same sector(s). The bandwidth capacity of the antenna unit is split among the radio band(s) allocated to sector(s) allocated to the antenna unit. The sectorization of the radio band(s) and the antenna units can be configured and/or altered based on capacity needs for given radio bands in antenna coverage areas provide by the antenna units.
