the new network you would like the radio to be a member of and click OK. The radio will be
automatically moved to the destination network and updated with the destination network’s
network ID.
Note UtiliNet radios may only communicate on one network at a time. You will not be
able to communicate to the integrated meter radio over-the-air until you move your
locally connected radio to the same network.
For more information on UtiliNet module configuration, transparent port configuration, and
routing configuration see the UtiliNet Technical Reference Guide.
Chapter 3 Network Engineering
This chapter discusses the network design plan, calculation of latitude/longitude, RF considerations, field
studies and use of directional or gain antennas.
Network Design Plan
A UtiliNet network consists of two or more UtiliNet packet radios that communicate data to and from
points in the network. When designing a UtiliNet network, it is important to remember that UtiliNet
combines three different technologies: a connectionless (store and forward) mesh architecture, packet
switched data transfer, and spread spectrum radio techniques. Since this combination of technologies
affects the design layout and plays a part in the overall optimization of the network, each one is discussed
in this chapter.
OSI Layers
For those familiar with the Open Systems Interconnection (OSI) model, the above technologies, or OSI
layers, also address why a UtiliNet network communicates like a computer network. In fact, it is often said
that UtiliNet radios are computers that use radio waves to communicate with each other, or that end devices
do not talk through UtiliNet radios but to them. From a certain point of view, this is true. UtiliNet radios
are computers first and spread spectrum radios second. Truly optimizing the benefits of a UtiliNet network
requires understanding the interaction and purpose of the physical, data-link, network, transport, and
session layers of the OSI model.
