Abstract: A method of providing communication between a wireless mission critical communication link (MCCL) and a wired MCCL, comprising: determining a wireless communication cycle of a primary device coupled to the wireless MCCL; determining a wired communication cycle of a secondary device, wherein the secondary device is coupled via the wired MCCL; receiving a feedback signal from the secondary device over the wired MCCL; synchronizing a start time of the wireless communication cycle to a start of the wired communication cycle; and transmitting the feedback signal over the wireless MCCL to the primary device at an aligned start time of the wired communication cycle.

Abstract: 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.

Abstract: A communication method between a master and a device, the master transmits in a subcycle a received condition message (RCM) for an immediately prior subcycle, wherein the RCM is an ACK when a transmission from the device in the preceding subcycle was correctly received and the RCM is a NACK when a transmission from the device in the preceding subcycle was not correctly received, comprising: including in each transmitted condition message a current priority data acknowledgement flag (CPDAF), the CPDAF being transmitted set in each condition message for each subcycle of an offset cycle after the master correctly received in a current cycle a priority data message, the offset cycle being defined as the second and subsequent subcycles of a current cycle and the first subcycle of a next cycle, the CPDAF being transmitted as cleared otherwise.

Abstract: A method for hub for interfacing between a wireless mission critical communication link (MCCL) and a wired MCCL. The hub includes a wired interface a providing a physical layer connectivity to the wired MCCL; a plurality of ports coupled to the wired interface; a wireless interface providing a physical layer connectivity to the wireless MCCL; and a processor; and a memory containing instructions that, when executed by the processing circuitry, configure the hub to: receive a signal from a primary device through the wireless MCCL; determine a wireless communication cycle of the primary device; determine a wired communication cycle of a secondary device, wherein the secondary device is connected via the wired MCCL; synchronize a start time of the wired communication cycle to a start of the wireless communication cycle; and send the received signal to the secondary device at the synchronized start time of the wired communication cycle.
