What DSMX adds to the tried and true wideband technology of DSM2 is the extra interference protection and faster reconnection times of frequency agility. But DSMX is anything but a common frequency hopping system.
Agile: quick and well-coordinated in movement
DSMX frequency shifts are coordinated using the most advanced spread spectrum algorithm ever seen in an RC application. Unlike other FHSS transmitters that all hop in the same fixed patterns, every DSMX transmitter has its own unique frequency shift pattern calculated using its GUID (Globally Unique Indentifier). 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 2.4 band, DSMX transmitters provide quicker reconnection times and superb response in the noisiest 2.4GHz environments.
Just How Good is DSMX?
In multiple tests, 100 DSMX systems were operated simultaneously for extended periods of time. During these tests not a single case of RF link loss, latency increase or control degradation was experienced or recorded. See the 100 transmitter test for yourself.

Is DSM2 and DSMX equipment compatible?
Yes! DSM2 transmitters are forward compatible with DSMX receivers and DSMX transmitters are backward compatible with DSM2 receivers. And because DSM2 and DSMX share the same wideband DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they're using DSM2 equipment, DSMX equipment or a combination of both.
It is important to note, however, that the only way to experience the full benefits of DSMX (wideband DSSS plus frequency agility) is by pairing a DSMX transmitter with a DSMX receiver.
Are DSM2 Transmitters eligible for a DSMX add-on?
Yes, but the difference a DSMX system makes is really only apparent when hundreds of 2.4GHz systems are in use at once. DSM2 users who rarely, if ever, fly in big events or other exceptionally "noisy" 2.4GHz environments will find the DSM2 equipment they have now is all they will ever need. In typical RC environments like the local flying club or the neighborhood park, DSM2 is still consistently faster, more robust and more precise than any other narrow-band 2.4GHz solution.
