Raveon’s RV-M7 WX data radio modems are high-speed FCC and CE certified data radios designed for telemetry, SCADA, AVL, wireless data, mobile-data and remote control applications. The WX version houses the M7 in a weatherproof IP65 rated aluminum enclosure. With fast over-the-air data rates and fast transmit-to-receive switching, Raveon’s M7 UHF data radio transceiver increases data throughput in narrow-band wireless systems. . Included in each unit, are advanced networking, error correction, and diagnostics. It may be ordered with an IP65 weatherproof enclosure. And because it is the only radio modem built using rugged “single-board” construction, it is extremely rugged – and cost effective. The Optional internal GPS ( GX option) enables the M7 to transmit its position, data, and status (voltage, speed, heading, temperature, I/O bits..) a pre-set intervals using either conventional carrier-sense methods or with efficient TDMA channel access. A GPS tracking system built with M7 transceivers, can track up to 20 radios with one-second updates or 200 with 10-seocond updated. The M7 is the fastest most efficient UHF AVL radio available. The M7 leads the industry in many areas including technology, features, and price. It has some of the fastest over-the-air data rates, TX-RX switching times, and power-on times. It is one of the smallest data radios in its class. It is one of the most rugged data radios made. It is one of the lowest power-consumption radios available. And its price will pleasantly surprise you.
