Chapter 3: Module Description
The Itron Riva Modular LE (module) is a single full modular low energy radio communications device. The
module is designed for integration into 3rd party host devices wanting to communicate by radio frequency
(RF) on an Itron Riva network. As shown in Figure 2, the module is contained inside the silver rectangular
perimeter and is fully shielded (shield is removed in this image). The module and can reside on an Itron
host board or be integrated with any host as a standalone module.

The module is designed for low energy applications (including battery powered). The module includes a
communications processor that sleeps whenever possible to conserve power. The microprocessor uses
an external 32.768 kHz mems oscillator and an internal resistor-capacitor (RC) oscillator at up to 40 MHz
when awake and processing/sending/receiving data. The module has modulations ranging from 150 kbps
GFSK down to 10 kbps GFSK at maximal ranges and can operate in other modes including 100 kbps
FSK, 50 kbps FSK and 16384 bps OOK.
ITRON RIVA MODULAR LE HIGH-LEVEL ARCHITECTURE
The Itron Riva Modular LE has a dedicated communication processor for handling RF connection to Itron
developer boards and devices, Cisco CGRs, and other compatible hardware, via Itron’s Riva network.
The module can be integrated with a dedicated application processor for interfacing with sensors,
actuators and custom devices.
The diagram shown in Figure 3 depicts the layers and communication protocols for the Itron Riva Modular
LE and a sample host with application processor (which is any host board that can be integrated with the
module).
The host will provide the power supply and antenna connectors.
