The FLARM device is definitely useful for avoiding collision in sailplane.
But the company behind maintains it’s monopoly position arguing that’s it’s safer and cheaper for the users:
This text is just regular company’s crap, to reassure themselves (and the shareholders) they can maintain a high level of monopoly (and profit).
They also state the radio protocol is patented:
Unfortunately, there is no such thing as copyrighted radio protocol!
My prefered part is it when the founder respond this accusation of being obscure and avoid implementation in many hardware device, and in software such as XCSoar:
The best part it: they managed to impose the device, not only in competition but for any sailplane in France. How comes the FFVV (French Gliding Federation) can make a device mandatory without any alternative?
One person, Hiram Yaeger seemed to have reverse engineered the protocol:
If interoperability by documentation or standardization would not be possible, even in RF, there would be no GSM, no GPRS, no WIFI, no Bluetooth.
What do you thing you are FLARM? You are just making a simple electronic device broadcasting GPS position in the free RF band, and it’s not even EASA / CAA / FAA certified! (just like any regular babyphone)
Step down while you can and publish this RF protocol, or the community will do it for you sooner or later! (and no update of the 10k units released in the world will save you)
