The PHY transmits or receives bits of data using a 2.4-GHz Radio
- Uses GFSK modulation in the 2.4-GHz ISM band
- Operates at 1-Mbps data rate
- Consists of 40 RF channels with 2-MHz of spacing between channels
37 channels for data, 3 channels for Advertising
- RF Output Power: -18 dBm to +3 dBm (0.01 mW to 2 mW)
- BLE Receiver Sensitivity: -89 dBm
Spacing of channels in the BLE PHY allows Advertising in the crowded 2.4-GHz ISM band
