Basic ARCi Internet – System Description
Multi-Sector Hub Configuration
The Multi-Sector configuration consists of two or more ARCi Hub antennas mounted on a
common building roof or tower/monopole structure served by a single Wireless Hub (WMTS)
located in an adjacent equipment room.
As each Hub antenna covers a sector sixty degrees wide, six ARCi Hub antennas are required for
complete 360-degree coverage. Fewer Hub antennas may be required depending on the
relationship of the Hub site to the geography to be covered by the system.
Each hub requires a separate Upstream and Downstream IF cable, so a six sector (six ARCi Hub)
installation would require 12 IF coaxial cables. Refer to figure C1. The DC power and telemetry
cables are simply paralleled in a multi-sector configuration. This can be accomplished by running
separate power/telemetry cables from each ARCi Hub antenna to the equipment room, or by
installing an Outdoor Junction Box (OJB) on the mounting structure adjacent to the Hub antennas
and paralleling the DC power and telemetry in the OJB.
See the
Hub Installation Details section of this manual for more information.
