What is Digital Spectrum Modulation?
Back to Resources
DSM or Digital Spectrum Modulation is a form of digital spread spectrum modulation that had been developed and optimized for R/C use.
What channel will I be on?
The DSM system scans the 2.4GHz band and finds a channel that is not being used. Once an open channel is found the transmitter begins transmitting on that unused channel. The DSM System has an available spectrum of 79 channels. In the unlikely event that the spectrum is full, the 80th system will not connect or cause any interference, going into "hold scan" until a channel is free.
Won't other 2.4Ghz devices like phones and wireless computers cause interference?
No, the FCC requires that all 2.4Ghz DSS devises be "smart"- incorporating collision avoidance such that when any DSS system is turned on, it scans the 2.4GHz band until a channel that is not being used is found then begins transmitting on that unused channel.
What is the range?
Typical range is about 3000ft. depending on conditions.
What kind of response time does Spread Spectrum have?
Spectrum's DSM system is optimized to give the fastest possible response time of 5.6ms. Typical FM systems offer a response time of 12 to 18ms.
Will the DSM system affect or be affected by other transmitters on 27 or 75mhz or lap counting systems?
No. The DSM system operates in the 2.4Ghz ISM band and is well above the range of any equipment including lap-counting systems presently in use.
So I can just turn on my radio any time with out worry of getting or causing interference?
Exactly!
