Abstract
Downhole equipment and surface equipment communicate wirelessly with each other. A signal wirelessly transmitted at a first frequency from a downhole controller disposed within a wellbore is received at a surface location. The received signal is demodulated to a demodulated digital value. The demodulated value is added to an end of a buffer string. The buffer string is processed to determine whether the buffer string contains a message that is valid. In response to determining that the buffer string contains the message that is valid, the message is decoded. A command signal is wirelessly transmitted at a second frequency different from the first frequency to the downhole controller to adjust a state of the downhole controller.
