Introduction

The information in this document will provide guidance on proper
implementation of the Model 101-2017-025 Aclara Radio Module (ARM). The
ARM is a limited single modular transmitter that can be used on Aclara’s
proprietary end point devices to support Aclara’s RF network. Proper RF
performance, within Aclara’s licensed operating frequency band of 450 MHz to
470 MHz, can be achieved by following a few design guidelines. With the
module implemented properly, there is no need for repeating FCC transmitter
tests, saving both time and cost of final device certifications.
