Digital Spectrum Modulation: A Serious Upgrade For Hobbyists
Posted: under Technology.
"Digital Spectrum Modulation" or DSM is a radio technology currently being adapted to RC cars, helicopters airplanes, robots and trucks. One problem that frequently plagued RC hobbyists is radio interference when multiple players are controlling cars and planes. DSM aims to eliminate this problem by having the user's controller emit a narrow band signal that changes from one frequency to the next within milliseconds. This subset of DSM is called Frequency Hopping Spread Spectrum or FHSS. The ...Read the rest of this entry »
