Abstract:
A wireless communications system for a downhole drilling operation comprises surface communications equipment and a downhole telemetry tool. The surface communications equipment comprises a surface EM communications module with an EM downlink transmitter configured to transmit an EM downlink transmission at a frequency between 0.01 Hz and 0.1 Hz. The downhole telemetry tool is mountable to a drill string and has a downhole electromagnetic (EM) communications unit with an EM downlink receiver configured to receive the EM downlink transmission. The downhole EM communications unit can further comprise an EM uplink transmitter configured to transmit an EM uplink transmission at a frequency greater than 0.5 Hz, in which case the surface EM communications module further comprises an EM uplink receiver configured to receive the EM uplink transmission. More particularly, the downhole EM uplink transmitter can be configured to transmit the EM uplink transmission at a frequency that is at least ten times higher than the EM downlink transmission frequency.

Claim (Index 21):
The method as claimed in  claim 16  further comprising transmitting the EM downlink transmission in the form of a square wave signal, or a pulsed signal, or a sinusoidal carrier wave signal.
