The maximum range of the broadcast signal depends on the transmission power setting, as well as environmental factors. Signals can suffer interference, be diffracted or absorbed.
The Kontakt.io default transmission power (tx power) is set to -12 dBm. Transmission power level can be adjusted by the user with the Kontakt.io Admin App for iOS or Android (values 0-7 as shown below) or directly from your Web Panel, but then you need to synchronize those settings using the iOS or Android Administration App.

|f0||2||-16 dBm||-81 dBm||10|
|f4||3||-12 dBm||-77 dBm||20|
