About Spread Spectrum Radios
Spread spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This allows the communications to be more immune to noise and interference from RF sources such as pagers, cellular phones and multipath. Spread spectrum radios do not require an individual license nor frequency coordination through a regulatory agency. Higher receiver sensitivity and signal processing help to compensate for lower power compared to UHF or VHF systems transmitting 5 Watts.
Our spread spectrum radios provide wireless data communications, and support point-to-point and point-to-multipoint datalogger communications. They can serve as a field modem/radio while connected to the datalogger, a stand-alone repeater, or as a base station modem/radio when connected to a computer.
