The RF401 Spread Spectrum Radio has a 910 to 918 MHz operating frequency range, which is allocated to the US and Canada. Spread spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This improves communication performance in locations where RF noise, pagers, cellular phones and multipath could cause interfence. The RF401 reduces susceptibility to RF interference from similar spread spectrum devices by providing user-selectable frequency hopping patterns.
The RF401 spread spectrum radio modem supports point-to-point and point-to-multipoint datalogger communications. It can serve as a field modem/radio while connected to the datalogger or as a base station modem/radio when connected to a computer. The RF401 modem can also be used for general purpose wireless data communications.
