[Ble--physical Layer]

Briefly

BLE physical layer, may do IC or plate-pole hardware RF testing will be more concerned. is hardware-level.

Frequency bandwidth and channel allocation

BLE works in the 2.4 GHz ISM band 2400-2483.5 mhz,ism Band is common and does not require licensing for use in research, medical and other fields. BLE uses 40 RF channels and the channel-to-frequency relationship is as follows:
2402 + k * 2 MHz (k = 0, ..., 39)

Remaining features

Transmit Power:

Modulation mode:

BLE physical layer more involved in the RF hardware features, do IC design, IC testing, PCB RF performance testing needs to know more deeply.
