1 Overview
TUNet connects to residential and C&I meters, distribution equipment (e.g. reclosers, capacitor banks), load control devices,
fault indicators, and a variety of other devices. Data from the devices is transmitted over the wireless network to an NC-2202
Network Controller located at the base station radio site. The NC-2202 delivers the data to the utility’s operations and
customer service centers via any standard TCP/IP link (e.g. cable, fibre, satellite, public telephone).

Authorized utility operations personnel interface to the NC-2202 and manage the TUNet using a standard web browser. No
other software is required. Access to the web interface is restricted to users with an assigned username and password.
A 220 MHz Wide-Area Network (WAN) reaches the utility’s service area up to 20 to 30 miles from the base station. In
applications with large concentrations of devices, such as advanced metering, a Local-Area Network (LAN) collects data
from as many as 60 devices in a local area and relays the information to a WAN radio placed on a centrally located device.
