Basic ARCi Internet – System Description
Single Sector Hub Configuration
The ARCi Internet hub location consists of one or more ARCi Hub Antennas mounted on the
building roof or adjacent tower or monopole structure and its associated equipment located in the
interior hub equipment room. Signal and power cables are run from the hub antenna(s) to the
hub equipment room. See figure C1 on the preceding page.
The outdoor ARCi Hub Antenna
is mounted on a vertical pipe or tower leg, aimed at the
geographic area to be served. As each hub antenna covers a sector (arc) about 60 degrees wide,
from one to six hub antennas are required depending on the desired coverage. Each hub
antenna requires its own upstream, downstream and power connection to the hub equipment
room.
Refer to the
Frequency/Coverage Planning section of this manual for the details of antenna
coverage and frequency utilization.
The
Installation Details section provides mounting information, test access and system grounding
recommendations for the antenna and wireless hub.
The
ARCi Specifications section provides dimension, weight and mounting details.
Located in the equipment room
are:
1. Wireless Hub and its network manager system
2. Downstream Upconverter
3. 100 Mbps Ethernet switch
4. Gateway system
5. Router and ISP access equipment
6. Uninterruptible power supply system (UPS) to protect all hub equipment
7. DC power supply for the hub antenna electronics
The Wireless Hub (WMTS), Upconverter and Network Manager components are purchased from
ARCi or directly from Vyyo, Inc.
The Gateway and ISP access equipment are selected and configured according to the
requirements of the particular ISP and the backhaul facility between the hub site and the ISP
facilities.
The customer also must provide a DC power supply with sufficient capacity to operate the radio
equipment. The UPS is strongly-recommended to protect system operation throughout short
outages, as well as to provide isolation between incoming power line anomalies and the hub
electronic equipment. See the
Hub Installation Details section of this manual.
