Spread-Spectrum Radios

Spread-spectrum radios are very popular for creating wireless communication links to and between data loggers. These low-cost devices provide robust links ranging in speeds from 10 to 200 kbps and distances of 3 to 50 miles, depending on the radio model and operating conditions. These radios consume little power and are easy to install and maintain, as they have been designed for low-power, non-licensed operation. Spread-spectrum radios spread the normally narrow-band information signal over a relatively wide band of frequencies. This allows the communication to be highly immune to noise and interference from RF (radio-frequency) sources.
