Slightly unusual requirements for a show I'm working on - we're looking at getting XD-V headsets for operators of remote control aircraft, which also use 2.4ghz.
The r/c transmitters, held at the waist, will be very close to the belt packs and it's critical there's no interferance - from the faq it looks we might be okay ...
Another significant reduction of range can be expected if the receiver antennas for the XD-V systems are very close to other intentional radiators in the same frequency band such as Wi-Fi wireless access points
As our radiators are near the XD-V transmitter not the receiver.
A technical review of the RC system is here and this is what is on the product page:
ACCST 2.4GHz system shifts 80 channels around hundred times per second in the 2.4GHz band
Output Power:: 60mW
Resolution: 3072 (11bit)
Can any experts foresee problems or recommend say the v75 over the v70 or v55 ? (Price is a factor for us - we'll have max. of three wireless systems) Thanks!
