The continuous shrinking spectrum has given us the opportunity to find new solutions and face the upcoming problems related to noise, interferences, and reduced working bandwidth.
Our new UN "Ultrasonic Narrowband" technology, allows:
- Absolute protection from Ultrasonic interference (e.g. next-gen camera range trackers) thanks to a dedicated 70 dB filter
- Narrowband operations, to operate using half of the bandwidth and have an extra 50% range.
- Commute by SW to a wideband mode for compatibility with legacy Wisycom system
All of this with our pristine audio quality:
What is new after the update:

Narrowband
- doubles the amount of channels within the same range
- 50% more coverage

Narrowband/Wideband switchable
- maintains full compatibility with all previous Wisycom legacy receivers

Ultrasonic filter
- uses the best selective audio filter to avoid any ultrasonic interference
