NFMI: Communication coil for near-field magnetic induction set off a new wireless era.
A short-range, high-frequency radio technology that uses magnetic field induction to achieve wireless communication for high-end wireless headphones.
NFMI technical characteristics and limitations:
Ultra low power consumption (transmission of compressed 48K mono audio less than 2mA)
Immune skin tissue
You can work underwater (swimming or listening to music).
Coexistence and compatibility with other wireless technologies
Natural safety
The communication distance is short (less than 50cm) in small antennas and low power scenes.
Throughput is low (596kbps).
