Abstract
Embodiments of the disclosure relate to digital-analog interface modules (DAIMs) for flexibly distributing digital and/or analog communications signals in wide-area analog distributed antenna systems (DASs). In this regard, in one aspect, a DAIM is a multi-functional device capable of distributing the digital and/or analog communications signals to a local-area DASs in a wide-area DAS. The DAIM comprises an analog radio frequency (RF) communications signal interface for coupling with an analog signal source, a digital communications interface for coupling with a digital signal source, an analog local distribution interface for coupling with a remote antenna unit (RAU), and at least one digital remote distribution interface for coupling with a head-end unit (HEU) of the local-area DAS. By employing the DAIM in the wide-area DAS, it is possible to flexibly reconfigure the wide-area DAS for distributing digital and/or analog communications signals over the digital communications mediums.
