Authentication. Authentication is the process of confirming that an artifact is genuine or
valid. Authentication in the Cellular 500W remote module is the process of verifying a
request is from a valid source and in its original form.
■
Encryption. Encryption is the process of transforming information to make it unreadable to
anyone who does not have a valid security key. There are two types of encryption: symmetric
and asymmetric. Symmetric encryption uses a shared key to decrypt or encrypt information.
Asymmetric encryption uses a private key to encrypt and a public key to decrypt. Data
transmissions over the network are protected using AES-256 encryption.
Battery Life
Powered by a single non-replaceable, long-life lithium battery, the 5 pit module has an expected
battery life of 20 years, dependent on use case.
Low Battery
Cellular 500W remote modules include a low battery indicator that helps utilities proactively plan
and manage field module replacements.
Note: Low battery functionality is based on the module's firmware version. For more
information, see Firmware Functionality on page 13.
Transmission Modes
The Cellular 500W remote module is an IPv6 Wisun compliant device that operates in Mobile
Mode or OpenWay Riva Network Mode.
Mobile Mode
In Mobile Mode, the module transmits every nine seconds over multiple RF channels to report
on:
■
meter register value
■
cut cable or communication error event
■
reverse flow (encoder version selected)
■
system leak status
■
low battery indicator
Network Mode
In OpenWay Riva Network Mode, the module reports four interrogation cycles daily. Each
interrogation collects six hours of 3,840 buckets of interval and event data. Interval data is
configurable from 1 minute to 1 hour (for example, 160 days of hourly data or 40 days of 15
minute data). Interval options are 5, 15, or 30 minutes.
