// The Sigfox network operates on public frequencies. To comply with
// radio regulation, it can send radio data a maximum of 1% of the time
// to leave room to other devices using the same frequencies.
//
// Sending a message takes about 6 seconds (it's sent 3 times for
// redundancy purposes), meaning the interval between messages should
// be 10 minutes.
//
// Also make sure your send rate complies with the restrictions set
// by the particular subscription contract you have with your Sigfox
// network operator.
//
// FAILING TO COMPLY WITH THESE CONSTRAINTS MAY CAUSE YOUR MODEM
// TO BE BLOCKED BY YOUR SIFGOX NETWORK OPERATOR.
//
// You've been warned!
