2.4Ghz - DMSS (JR)

Dual Modulation Spectrum System is JR’s own 2.4GHz protocol. A later entrant into the 2.4GHz market, DMSS can be considered as the truly ‘state of the art’ method of providing radio control for model use. And since JR have not rushed their own 2.4GHz protocol into production they have been able to incorporate the very latest techniques for ‘Wideband Data Transmission’ into the next generation of JR radio control sets.

DMSS combines the best features of Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) protocols. FHSS is great for avoiding interference and DSSS offers high response. JR DMSS combines both these attributes, having both frequency hopping and high response.

The JR DMSS system uses a greater than 3Mhz wide signal as compared to the majority of others which utilise a much narrower [1Mhz or less] signal.

If we know anything about spread spectrum signals, a wider base signal [3Mhz Vs 1Mhz] allows for a huge increase in noise and interference immunity performance and at the same time allowing for much faster data bandwidth/throughput.

The fact that DMSS is actually using quite a wide bandwidth signal is a huge advantage in 2.4GHz performance and it will provide superior performance over any other current 2.4GHz system that is currently available.

DMSS also offers ‘Two-Way Communication’ (telemetry) with receiver voltage monitoring as standard. Other types of sensor are due soon, with Temperature and RPM sensors being the next types to become available from JR in late June.

Probably the most important thing about JR DMSS is that it is 100% pure JR, with no involvement from any other outside company. This means that JR are back in full control of product development, so they can now concentrate on doing what they do best – making what are arguably the world’s best quality radio control systems.

NOTE:  DMSS is not compatible with DSMX or DSM2 Receivers.
