A DAS will often be shared between several mobile operators, and it is a great concern for each operator that their signals are not corrupted by spurious signals generated by other operators’ equipment.
One of the great advantages of a digital DAS is that each incoming signal is filtered into a discrete digital data flow, with no possibility of interference between signals for each operator. However, if a common analogue interface is shared at the head-end then there is still a risk of interference between operators being picked up before the signal is digitized.
The Maven Orion master node implements 8 separate band modules, each with their own independent analogue to digital interfaces. This high density makes it cost-effective to provide a dedicated interface per operator, eliminating any concerns about interference.
