In terms of working, Milo is a radio and will therefore transmit and receive like any radio can, unless someone is broadcasting something in that region that blocks or interferes with the frequencies Milo uses.
With that being said, It is likely that use of all radios and communication devices, including Milos, is restricted in National Radio Quiet Zones – areas where radio transmissions are restricted by law, for example to facilitate scientific research.
Always be familiar with all rules and regulations for the area you’re in. If you’re uncertain, we recommend that you contact any regulatory group where you plan to use Milo to make sure it complies with any rules. It is your responsibility to use any communication device according to applicable rules.
