Abstract
Embodiments described herein provide for a distributed antenna system (DAS) including a host unit and a plurality of active antenna units (AAUs). The host unit is configured to send management information to the one or more RAN nodes. The one or more RAN nodes are configured to manage the RF signals based on the management information.
Claims19
A host unit for use within a distributed antenna system having a plurality of antenna units configured for communicatively coupling with the host unit over communication links, the host unit comprising:
- circuitry configured to:
- communicate radio access network signals with at least one radio access network node, the radio access network signals including an analog version of a radio frequency signal modulated with at least one of an over-the-air radio access modulation protocol or digital samples corresponding to a radio frequency signal modulated with an over-the-air radio access modulation protocol;
- convert between the radio access network signals and respective transport signals;
- communicate the transport signals with the plurality of antenna units;
- and
- send management information to the at least one radio access network node, wherein the at least one radio access network node is configured to manage the radio frequency signals based on the management information;
- and
- wherein the plurality of antenna units are configured to convert between the transport signals and the radio frequency signals modulated with the over-the-air radio access modulation protocol, and to wireless communicate with at least one wireless device using radio frequency signals.
