Chapter 2: Overview
This document provides information on the design, construction, and operation of the Itron Riva Modular
LE device (module).
The module is a fully shielded communications device which can be integrated into a host device where it
provides communications capability for joining the Itron OpenWay Riva network. The module is used with
an external antenna.
The module housing is a lead free, non-vented, surface mount shield that provides protection for the
internal components. Power may be supplied from a host supply ranging from 5VDC to 9VDC or by
batteries.
This module contains the cutting-edge communication technology featuring IPv6 RF to route messages
and data between the host device and the head-end system on an Itron OpenWay Riva network.
Intelligence in the module chooses the communication link quality and modulation scheme that support
the best possible data rate. This is done automatically in real-time by the module without any need for
pre-programming or path hard-coding. The communication modules create their own multi-hop
environment using the best available physical path for communication where the routing is managed by
standardized IETF routing protocols that are independent of the physical link. Itron’s technology offers a
unique way to deploy the same communication module anywhere, regardless of traditional network
design considerations, such as geography, density, or structural environment.

The module was certified for operation in multiple configurations of the FSK, GFSK, and OOK modes
within the 902=928 mHz frequency range. The module employs channel hopping and channel
separation, The low, mid, and high channel frequency was recorded for each configuration.
