1 Overview

As illustrated in Figure 1, the main components of the system include:
The BSR-757 Base Stations, described in this guide.
The wireless modems. The Base Station supports two modem types:
V390i – this is an industrial wireless modem located in the utility substation sites.
It includes a V384 data modem with additional interfaces, such as four serial
ports (typically for SCADA devices), three Fast Ethernet ports, and a WiFi
access point. This modem is described in the V390i User Guide.
V384 (monitoring modems) – this is an indoor UHF band A data modem, which
is part of the BSR. It is used to monitor the RF signal quality of a sector.
The NMS, described in the NMS User Guide.
Overview of the Base Station
The Arcadian Networks BSR is a pre-configured rack, containing all the components
necessary for operating a secure wireless network for communications.
The BSR is designed to provide broadband wireless connectivity over two 1 MHz wide
bands in the 700 MHz A-Guard Band frequencies, separated 30 MHz from each other.
These 1 MHz channels are divided into three equal subchannels, each subchannel
being delivered via each one of a three sector antenna array providing a frequency
diverse coverage area from each base station tower site. Each BSR has three discrete
RF paths to and from its Wireless Modem Termination System (WMTS) to the sector
antennae. The antenna is typically installed on a 100-300’ height must. The base
station transmits a “Downstream” RF signal to the CPE, and receives an “Upstream” RF
signal from the CPE.
This document describes the three-sector Base Station configuration. One-sector or
two-sector configurations are optional, either for Omni coverage, or for support of two
sectors out of three. Where a three-sector configuration includes three RF
subcomponents (Upconverter, PA, LNA, Downconverter, etc.), the one- or two-sector
configurations include the corresponding one or two RF subcomponents. All sections of
this document are relevant also for the one- and two-sector configurations.
