Patent number: 11156979Abstract: A novel and useful acknowledgement and adaptive frequency hopping mechanism for use in wireless communication systems such as IO-Link Wireless. One or two additional acknowledgement bits are added to packet transmissions. One is a current acknowledgment bit which indicates whether a packet was successfully received anytime during the current cycle. The second bit is a previous acknowledgment bit which indicates whether packets were received successfully anytime during the previous cycle. An adaptive hopping table is constructed using a greedy algorithm which chooses frequencies with the best PER for transmission of higher priority packets, while equalizing the PER products across cycles. A last resort frequency mechanism further improves transmission success by switching to a better performing channel for the last subcycle when previous attempts to transmit a high priority packet have failed.Type: GrantFiled: October 14, 2019Date of Patent: October 26, 2021Assignee: Coretigo, Ltd.Inventors: Dan Wolberg, Ofer Blonskey, Ofri Olinky, David Marks, Omer Ephrat, Nir Efraim Joseph Tal
