Abstract: There is provided mechanisms for automatic gain control in a wireless communication network for power grid control. The wireless communication network employs time based scheduling of packets. A method is performed by a packet receiver in the wireless communication network. The method comprises receiving a packet from a packet transmitter. The packet comprises a preamble. The preamble is composed of a single OFDM symbol. The preamble is represented by a sequence of samples. The method comprises applying automatic gain control to the sequence of samples after variable gain amplitude control has been applied to the sequence of samples. The automatic gain control involves applying an LPF to the sequence of automatic gain controlled samples. The LPF is selected from a bank of LPSs. Which LPF to apply depends on, according to the time based scheduling, from which packet transmitter the packet is received.

Abstract: A method can be used for channel access in an industrial wireless network. A network controller allocates time/frequency resource units in a set of guaranteed timeslots to packet transceivers in the industrial wireless network. The guaranteed timeslots are timewise divided into slots and frequency wise divided into channels, where one slot-channel pair defines one time/frequency resource unit. The network controller provides to the packet transceivers information about the time/frequency resource units allocated to the packet transceivers. The packet transceivers map packets of their own traffic flows to their allocated time/frequency resource units in each set of guaranteed timeslots. The packets for each packet transceiver are mapped according to priority-based scheduling of its own traffic flows and independently of any mapping of packets of other packet transceivers in the industrial wireless network.

Abstract: A communication method for wireless communication uses a TDMA (Time Division Multiple Access) super-frame structure for scheduling uplink and downlink transmissions between a first node and a second node, the second node receives receiving a downlink transmission from the first node and transmits an uplink response to the first node. The transmission of the uplink response is performed in an uplink frame of the super-frame structure. The uplink frame includes a field for uplink payload data and a field for time indicating data. The transmission of the uplink response includes transmitting time stamps in the time indicating data field, the time stamps indicating a time instance of the receiving of the downlink transmission, and the time instance of the transmitting of the uplink response. The time instances are determined using the clock of the second node.

Abstract: A method, a communication device, a computer program, and a computer program product for cyclic time-slotted operation in a wireless industrial network. The communication device includes a memory having a first memory area and a second memory area. The method includes running an application software at application layer. The application software is associated with a first pointer. The method includes operating a communication hardware at physical layer. The communication hardware is associated with a second pointer. The first pointer and the second pointer in a given timeslot point at a respective different one of the memory areas, such that in the given timeslot the application software is enabled to access one of the memory areas and the communication hardware is enabled to access the other of the memory areas. The method includes swapping the pointers to the memory areas at the end of each cycle of the cyclic time-slotted operation

Abstract: A safety network for supporting one or more devices in intermittent use, the safety network being susceptible of verification and/or validation as a safety loop and including a safety controller configured to
assess the integrity of the safety network, and
monitor safety sensors and cause safety actuators to respond to any detected safety events in accordance with safety rules.
The safety network implements safety representatives, each configured to
maintain a virtual representation of an associated device in intermittent use, including at least one virtual safety sensor and/or virtual safety actuator,
make the virtual representation available for integrity assessment and monitoring by the safety controller, and
perform wireless data synchronization between the virtual representation and the associated device.
The virtual representation further includes an activation indicator, which determines a safety rule for the safety controller's monitoring and/or for the safety representative's data synchronization.-

Abstract: An industrial robot adapted for operation in a factory environment includes: sensors, actuators, a robot controller and a wireless interface configured to establish a sidelink to a further industrial robot or a group of industrial robots after a successful proximity verification. The industrial robot is configured to participate in execution of a utility task, which is carried out in collaboration with the further industrial robot or at least some members of the group of industrial robots, said collaboration including an exchange of operational data over the sidelink. An example utility task is the coordinated transfer of an object by multiple participating industrial robots. Another example is the collecting of map information by multiple participating industrial robots.

Abstract: A control network for supporting multiple industrial automation devices which operate in radio coverage of at least one radio access network includes: a processor configured to execute applications; at least two wireless network interfaces, each configured to communicate with the automation devices; and a traffic controller configured to provide a logical connection from an executing application to one of the automation devices by maintaining at least two contemporaneous physical connections using respective wireless network interfaces and the radio access network. The control network is further configured to repeatedly adapt a physical redundancy of the logical connection. In some embodiments, the control network is configured to determine a level of independence between the physical connections on the basis of measurements, and adapt the redundancy accordingly. The level of independence may be determined by comparing time series of a quality-of-service related quantity.
