DSMX:True Evolution. The Addistions to DSM2 that make DSMX DSMX


DSMX. True Evolution

Spektrum launched the 2.4GHz RC revolution. Since then millions of hobbyists the world over have come to embrace 2.4GHz technology as the way to race and fly. Spektrum leads the way yet again with DSMX; the world's first wideband, frequency-agile 2.4GHz signal protocol and the most advanced spread spectrum RC technology to date.

DSMX is a natural evolution of DSM2™ technology that is the result of several years of development. It builds on what has come before and takes DSM to the next level of robustness, reliability and efficiency without leaving current DSM2 users behind.

Spektrum DSM2 - The Foundation OF DSMX


The Evolution of Spektrum

The evolution of Spektrum now adds a third element to the foundation that is DSM2, to create DSMX. This provides improved security when hundreds of 2.4Ghz systems are being used simultaneously.


Wideband DSSS

A Solid Foundation: Wideband DSSS
The foundation DSMX is built on is the same foundation as DSM2 – the superior on-channel interference resistance and coding gain of wideband DSSS. Compared to the wideband signal of a DSM2 or DSMX system, the narrow-band signal of other 2.4 transmitters is more likely to suffer crucial data loss in the event of on-channel interference. Think of wide-band 2.4 as a river and narrow-band 2.4 as a stream. It takes much more interference to stop a river than it does to stop a stream.

The big reason wideband is so robust is coding gain. Essentially what this means is that the unique coding in a DSM2 or DSMX wideband signal allows it to be heard well above the noise of surrounding 2.4GHz signals without requiring any more power. In fact, a Spektrum wideband signal can achieve as much as 3X the range of its narrow-band competition using the same amount of power.


3D Spread Spectrum
In addition to its wideband DSSS foundation and smarter frequency agile protocol, DSMX users will enjoy a third dimension of signal protection that DSM2 users have always enjoyed. Only Spektrum full-range receivers offer the patented advantage of MultiLink™ dual-path redundancy. When combined with the superior wideband power and frequency agility of DSMX, MultiLink gives RC pilots the fastest, most reliable 2.4 RC technology available in any signal environment.

And now with DSMX the 'X'-tra Benefit of Frequency Agility


Smarter FHSS

Frequency Agility
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. Go to spektrumrc.com and watch the DSMX video.

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.
