// The radio model describes the physical device that is capable of transmitting
// and receiving signals on the medium. It contains an antenna model, a
// transmitter model, a receiver model, and an energy consumer model.
//
// The radio model supports changing radio mode, transmission power, or bitrate
// via ~ConfigureRadioCommand, or with direct C++ function calls.
//
// `switchingTimes` parameter should be regarded as a 5x5 matrix:
// <pre>
//               OFF SLEEP RECEIVER TRANSMITTER TRANSCEIVER
// OFF           0 0 0 0 0
// SLEEP         0 0 0 0 0
// RECEIVER      0 0 0 0 0
// TRANSMITTER   0 0 0 0 0
// TRANSCEIVER   0 0 0 0 0
// </pre>
// The corresponding `RadioMode` pairs contain the time needed to
// switch from one state to another.
// For example: the 6th number identifies the time needed to switch
// from SLEEP to OFF.
//
// The first entry of the `switchingTimes` string indicates the
// time-related metric prefix and it MUST be s, ms or ns.
