InterReach Spectrum supports up to eight frequency bands in a single system. Each antenna
location supports those bands in modular, group pairings. Each location includes a Main Remote
Access Unit (MRAU), which can power up to three additional Secondary Remote Access Units
(SRAUs). An MRAU supports two frequency bands, and each SRAU can support up to two
frequency bands, for a total of up to eight frequency bands.
MRAUs and SRAUs are grouped logically, based on common service provider groupings and
include, as an example:
•
850/1900
•
700/700 MIMO
•
800/900 SMR
•
1900/AWS.
To add more frequency bands, you connect an SRAU to the existing MRAU.
