1. BLE4.1 devices operate in the unlicensed 2.4 GHz ISM (Industrial
Scientific Medical) band. BLE4.1 wireless technology has 40 channels
(3 broadcasting channels, 37 data channels), each channel spacing
2MHz, over the entire operating frequency range: 2.402-2.480GHZ.
A frequency hopping transceiver is used to combat interference and
fading. The modulation method is GFSK, the output power is 0 dBm,
and the maximum transmission range is 10 m.
