I need to read data from a rotating wheel,one way, required data rate >2Mbps.
I can place an antenna only on the perimiter. the distance between rx and tx antenna can be small (10mm).
The wheel rotates at 22 000 rpm, diameter about 20cm.
there is already a coil for delivering the power to the wheel.
Can anyone suggest some solutions to the problem? Are there any integrated solutions that can be used at >2Mbps ?
I imagine this could be some kind of active RFID chip, or something completely different.
Chips like Chipcon have a data rate that is too slow for me and I don't know whether tx-rx would work when rotating at 22000rpm.
