” The range of the unit can be unlimited depending on how the back end is set up.”
That’s really cool technology for such a tiny unit.
Just think of all the things we can do now that we have communications devices that have an “unlimited” range.
No more unsightly communication towers and we will have tiny radios that can pick up any radio station on the planet, or maybe even some other planet.
Unlimited range is groundbreaking technology!
“unlimited range” comes from internet connected transmitters.
For example, the transmitter is at the event location and connected to a LAN via cable or Wifi. An operator logs into a computer anywhere in the universe and logs into the transmitter...and there’s your unlimited range. It likely requires the earbud receiver to be fairly close to the transmitter, about 100 feet or so.
