Hello everyone!

I've noticed that as days goes by, there is more and more wireless steering wheel systems being sold:

The thing is:

Is it safe for racing conditions? I mean, what are the odds of radio interference?

If we have a full grid running with these systems, it will be a lot of devices running on the same frequency right? Have someone experiencied some issues with any of them?

Another thing, does some one know what kind of RF these modules uses?

It is Wi-Fi, BlueTooth, or another type?

Great question. I've decided not to play guinea pig based on similar concerns and haven't used them yet.

For now I'm happy with the combination of a pass through wiring quick release wheel hub and CAN wheel system which avoids the curly chord mess and retains a physical connection, but curious to hear about experience with other systems!

I played around with one of the earlier wireless units that came on the market, this used Infra Red and it was next to useless. It didn't work when the wheel was turned more than ~120° in either direction or if the sun shined into the car. It also had horrendous latency issues. They was upgraded to a wireless radio based unit that worked a lot better, as long as the driver radio wasn't transmitting, then it dropped out (not useful when the radio button was using that system). Since then that car has gone back to a wired connection.

I have heard patchy feed back on the latest systems, with some working well and others not so well. The other issue is that different countries have different radio frequency ranges available for free usage, so it may be that a system that works well in one country, doesn't work as well in another as the frequency range that it uses is used for other purposes.

Thanks for the feedbacks.

I think Cartek uses this IR system, and this was exactly what I was concerned about it, when the wheel is turned, it may get off sight and lose comms.

Another issue is regulations. Brazilian telecom regulations are very strictly. Ok, I know ANATEL (brazilian government agency that regulates this kind of things like smartphones, bluetooth devices, wireless devices and so on), will not knock on my door if I bring one or two wireless steering wheel devices that is not homologated by them, but if we decide to use in a whole category with 20+ cars using it, it mighty bring their attention.

I think this kind of devices don't need any king of homologation in USA, I'm right? I've bought a lot of stuff in US (link cellphones, tablets, laptops) and never saw a single sticker or mark.

I use a wheel that connects via the column, so there's no cord. The connector supports 7 pins, which is enough for CAN and a couple of analog ground-based switches.

Parsonsj, which connector does this wheel uses?

What kind of wheel it is?
