This guide describes the installation process for Gridstream Network Concentrators (concentrators).
Any training provided directly to installers by the utility or by the Gridstream project management
team takes precedence over this guide.
About the Landis+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 endpoints 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 Take Out Points (TOP)
and concentrators. The LAN is the RF link between the concentrator and endpoints with UtiliNet
modules installed. Endpoint data transmits via radio frequency (RF) to the concentrator where it is
stored and processed. The concentrator transmits the data via RF to the TOP and then to the utility.
This chapter details the concentrator installation process.
About the Concentrator
The Concentrator is a device that receives one-way endpoint data from the Gridstream network,
processes that data, and sends it to a Collector (Take Out Point, or TOP). It also receives and passes,
but does not process, 2-way data. The concentrator contains:
• a LAN radio (BLT 3 or BLT 5)
• a WAN radio (UtiliNet IWR)
• a power supply
• a processor board (CPU)
• a battery pack in case of an AC power outage.
