RF416

2.4-GHz Spread-Spectrum Radio

The RF416 spread spectrum transceiver has an operating frequency range of 2.45 to 2.46 GHz, which is used in many countries world-wide. The RF416 is a compact, rugged, low-cost transceiver intended for use in a variety of applications.

The transceiver transmits at a power level of 60 mW and frequency-hops among 25 channels to avoid interference with other devices. This improves performance in environments where RF noise, pagers, and cellular phones could potentially reduce communication between devices. The RF416 may be used without an individual FCC license.
