Cisco Connected Grid Modules for CGR1000 Series—WiMAX Installation and Configuration Guide
OL-26236-03
Hardware Overview
Hardware Overview
The WiMAX module is designed to be installed into the CGR 1000 Series Routers ruggedized
routers/concentrators designed for deployments in secondary substations within the electric utility
distribution grid. The WiMAX module is used mainly for uplink to the Neighborhood Area Network
(NAN) within the Smart Grid environment.
The main function of the WiMAX module is the WAN uplink over wireless 2.3GHz band in Distribution
Automation and AMI concentrator deployment. The WiMAX module runs on CG-OS.
