MDS Model 9810 Spread Spectrum
Model 9810 is a spread-spectrum modem, which operates under FCC
Part 15 rules to provide unlicensed operation for point-to-point and
multipoint radios. Spread-spectrum is a frequency-varying technique
that lets several spread-spectrum modems operate within the same
radio frequency band.
