First Claim
1. An apparatus configured to distribute radio bands in one or more sectors among a plurality of sectors in a distributed antenna system, comprising:
- a plurality of radio interfaces each configured to;
split a received downlink electrical radio frequency (RF) communications signal into a plurality of downlink electrical RF communications signals; and
control providing each of the split plurality of downlink electrical RF communications signals to one or more sectors among a plurality of sectors in a distributed antenna system configured for the radio interface; and
a plurality of optical interfaces each configured to;
receive the split plurality of downlink electrical RF communications signals from the plurality of radio interfaces;
control for which sectors among the plurality of sectors configured for the optical interface, the received split plurality of downlink electrical RF communications signals are provided to one or more remote antenna units (RAUs) communicatively coupled to the optical interface; and
convert the received split plurality of downlink electrical RF communications signals into a plurality of downlink optical RF communications signals, whereinthe plurality of optical interfaces are each further configured to;
split a received uplink optical RF communications signal into a plurality of uplink optical RF communications signals;
control providing each of the split plurality of uplink optical RF communications signals to the one or more sectors among a plurality of sectors configured for the optical interface; and
convert the received split plurality of uplink optical RF communications signals into a plurality of uplink electrical RF communications signals; and
the plurality of radio interfaces are each further configured to;
receive the plurality of uplink electrical RF communications signals from the plurality of optical interfaces; and
control for which sectors among the plurality of sectors configured for the radio interface the received plurality of uplink electrical RF communications signals are provided to one or more carriers communicatively coupled to the radio interface.

Abstract
Embodiments disclosed provide sectorization in distributed antenna systems, and related components and methods. The antenna units in the distributed antenna systems can be sectorized. In this regard, one or more radio bands distributed by the distributed antenna systems can be 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.
