Abstract
A near-bit wireless constant current short-distance transmission device has an emission part and a receiving part. The emission part modulates a signal and then wirelessly transmits the modulated signal to the receiving part. The emission part transmits an emission signal into a stratum according to a set rated emission constant current value, and dynamically monitors and adjusts the rated emission constant current value of the emission signal to obtain stable emission power.
