As noted above, in the example shown in FIG. 1, the DAS is implemented as a digital DAS. In a “digital” DAS, signals received from and provided to the base stations 106 and mobile devices of a user 108 are used to produce digital in-phase (I) and quadrature (Q) samples, which are communicated between the master unit 102 and remote antenna units 104. It is important to note that this digital IQ representation of the original signals received from the base stations 106 and from the mobile devices of users 108 still maintains the original modulation (that is, the change in the amplitude, phase, or frequency of a carrier) used to convey telephony or data information pursuant to the cellular air interface protocol used for wirelessly communicating between the base stations 106 and the mobile devices of users 108. Examples of such cellular air interface protocols include, for example, the Global System for Mobile Communication (GSM), Universal Mobile Telecommunications System (UMTS), High-Speed Downlink Packet Access (HSDPA), Long-Term Evolution (LTE), and Fifth Generation (5G) air interface protocols. Also, each stream of digital IQ samples represents or includes a portion of wireless spectrum. For example, the digital IQ samples can represent a single radio access network carrier (for example, a UMTS or LTE carrier of 5 MHz) onto which voice or data information has been modulated using a UMTS or LTE air interface. However, it is to be understood that each such stream can also represent multiple carriers (for example, in a band of frequency spectrum or a sub-band of a given band of frequency spectrum).
