Wireless I/O Radios, Modules & Sensors

Freewave Wireless I/O Family – Radios, Stand-Alone Modules, & Sensors

Freewave wireless I/O includes remote measurement, remote control, and data communications in one seamless package. The I/O products are scalable, and can be integrated into large or small SCADA systems and other industrial automation projects. The radios operate in either the 900 MHz or 2.4 GHz ISM bands. Various models have been developed to address different applications. A summary of each model is given below, and in addition, brochures are available for download that include detailed specifications. Please give us a call to discuss any of these radios.
