This paper discusses a new approach for wireless motion control. Existing wireless techniques suffer from large closed loop delays of several milliseconds, which is unacceptable in precision motion systems. These large delays aremainly caused by the protocol used, since these are optimized for transferring large amounts of data, not to minimizetransmission delay. A new protocol and wireless system are proposed that reduce the closed loop transmission delayto less than 300 microseconds. The system has been verified in a real control system, and measurements show theperformance, which is more than ten times better than existing techniques
