Abstract: A wireless communication device for a wireless network employing a wireless time division communication structure, where the wireless communication device includes a wireless transmitter, a wireless receiver and an access control unit, which is configured to order the wireless transmitter to transmit, in a contention interval, a priority setting of a wireless communication device competing for resources, where the priority setting is transmitted as a signal having a frequency representing the priority setting, order the wireless receiver to receive, in the contention interval, priority settings of other competing wireless communication devices as signals having frequencies representing these priority settings, compare the transmitted priority setting with the received priority settings and seize a following data interval if the transmitted priority setting is higher than the received priority settings.

Abstract: A wireless network managing device for a wireless network that is part of a process control system. The wireless network managing device includes a node determination element configured to receive an operator selection of at least one node in the process control system via an operator terminal and determine a field device implementing the functionality of the node, and a bandwidth control element configured to adjust a bandwidth assigned to the at least one field device in an auxiliary data section of a communication structure used by the wireless network based on the received operator selection in order to increase system responsiveness.
