Fast. Agile. Secure.
DSMR technology is exclusive Spektrum 2.4GHz radio control technology that can be used with any type of land-based RC vehicle or boat. Its range and response, particularly in noisy 2.4GHz environments, are superb. Its also backwards compatible with DSM2 and marine-specific Spektrum receivers.
A Solid Foundation: Wideband DSSS.
DSMR technology is built on the same wideband DSSS foundation used in DSM2 technology. Compared to the narrowband technology used in other 2.4GHz transmitters, Spektrum DSMR and DSM2 signals are far less likely to suffer crucial data loss in the event of on-channel interference. Think of a wideband 2.4GHz signal as a river and a narrowband 2.4GHz signal as a stream. It takes much more interference to stop a river than it does a stream.
The big reason wideband DSSS signals are so robust is coding gain. Coding gain allows a wideband signal to be heard above the noise of other narrowband signals without requiring any more power. In fact, a Spektrum wideband signal can achieve as much as 3X the range of its narrowband competition using the same amount of power.
Impressive Agility.
Along with its wideband DSSS foundation, DSMR technology gives you the extra interference protection and faster reconnection times of frequency-agility. DSMR frequency shifts are coordinated using the most advanced FHSS algorithm ever seen in an RC application. Unlike other FHSS transmitters that hop from frequency to frequency using the same fixed patterns, every DSMR transmitter has its own unique frequency shift pattern calculated using its GUID (Globally Unique Identifier). And each pattern uses just 23 channels in the 2.4GHz spectrum.
By adding the agility of unique frequency shifts to the superior interference resistance of a wideband signal, and limiting those shifts to a smaller portion of the 2.4GHz band, DSMR transmitters provide on-channel interference protection that is simply second to none. The result is quicker reconnection times and superb response in the noisiest 2.4GHz environments.
