Preface
This guide describes the installation and use processes for Gridstream Concentrators. Any training
provided directly to installers and users by the utility or by the Project Management Team takes
precedence over this guide.
About the Gyr Gridstream Network
The Gridstream Automated Metering Infrastructure (AMI) network transfers information from a
number of endpoints distributed over a large geographical area. The most common endpoint sources
are from electrical, gas, and water endpoints. The network includes a Radio Frequency (RF) Wide
Area Network (WAN) and an RF Local Area Network (LAN). The WAN includes Collectors (Take
Out Points, or TOPs) and concentrators. The LAN is the RF link between the concentrator and
endpoints with Gridstream modules installed. Endpoints transmit data via radio frequency (RF) to
the concentrator where it is stored and processed. The concentrator transmits the data via RF to the
Collector and then to the utility. This chapter prepares the reader for details and procedures that
appear in following chapters about the concentrator installation process.
About the Concentrator
The Concentrator is a device that receives one-way endpoint data from the network, processes that
data, and sends it to a Collector. It also receives and passes, but does not process, 2-way data. The
concentrator contains:
•
a LAN radio (BLT 3)
•
a WAN radio (Gridstream IWR)
•
a power supply
•
a processor board (CPU)
•
a battery pack in case of an AC power outage.
