Radiation lobe for nRF24L01+

Alessandro Spinato

I wonder if a couple (or three) of your module with PCB antenna as receivers could be used for triangulating the transmitter, could I have some hints about this, or a schetch of the module's directional sensitivity?

Thanks, Alessandro

    I don't think NRF24L01+ is a particularly good choice for this type of application since it doesn't even have an RSSI feature (I have reservations about the practicality of triangulation based on RSSI even when it exists, but without it there's not much you can do). NRF51822 would be a more suitable part (just don't get your hopes up, everyone keeps trying to do triangulation using commodity radios but unless you're in an anechoic room it's pretty hopeless in the presence of various fading modes, reflections etc). Time of flight is the logical solution but pretty hopeless using commodity radios.
