Abstract :
A truly wireless S/A interface with wireless power and wireless communication for real-time factory operation has been presented. WISA uses IEEE 802.15.1 radio transceivers, but adds an optimized TDMA protocol to support a high number (120) of S/As per BS as well as short cycle times (2,048 μs).
