4700 Duke Drive, Suite 200 900 MHz Radio Telemetry Module Description This document describes the features and architecture for a general purpose 900 MHz telemetry transceiver module with exceptionally long range and reliable communications. Architecture Radio Standard and IC Selection The module is designed around the Atmel AT86RF212 802.15.4 transceiver IC. The 802.15.4 radio standard is an especially good choice as it provides for operation under the FCC CFR 15.
4700 Duke Drive, Suite 200 Frequency Agility Incorporation of automatic ability to change operating frequency helps the radio pair avoid disruption due to on-channel interference. FCC rules mandate that products must tolerate occasional interference. One of the best strategies for doing so is avoidance. Radio Control It is desirable that integration of this module into various products be as simple as possible. This is achieved by use of the microcontroller to manage many basic radio and network functions.
