Abstract: A method for providing assured communications in a two-way wireless communications system is disclosed. An instruction is constructed at a first device for wireless transmission to a second device where the instruction is received by the second device and ultimately seen by the user. The instruction is transmitted as an instruction signal. The second device alters the instruction signal and transmits it back in altered form to provide an indication that the instruction has been received by the second device. The user of the second device informs the operator of the first device that the instruction has been seen by the user by transmitting a further altered version of the instruction signal to the first device. The disclosed method assures the operator of the first device that instructions are being received and acknowledged in a timely manner.
