1. A distributed antenna system (DAS) comprising:
a host unit; a plurality of active antenna units (AAUs) communicatively coupled to the host unit over a respective communication link, the AAUs configured to wirelessly communicate with one or more wireless devices, wherein the host unit is configured to bi-directionally communicate RAN signals with one or more RAN nodes, the RAN signals including an analog version of an radio frequency (RF) signal modulated with an over-the-air radio access modulation protocol or digital samples corresponding to an RF signal modulated with an over-the-air radio access modulation protocol, wherein the host unit is configured to convert between the RAN signals and respective transport signals, wherein the host unit is configured to bi-directionally communicate the transport signals with the plurality of AAUs, wherein the plurality of AAUs are configured to bi-directionally communicate the transport signals with the host unit, wherein the plurality of AAUs are configured to convert between the transport signals and the RF signals modulated with the over-the-air radio access modulation protocol, and to transmit and receive the RF signals, wherein the host unit is configured to send management information to the one or more RAN nodes, wherein the one or more RAN nodes are configured to manage the RF signals based on the management information. |
