Abstract
A wireless infrastructure node includes at least one processing device configured to receive a data packet from a wireless field device network (WFN) controller, where the data packet includes a network identifier. The at least one processing device is also configured to determine a field device network to receive the data packet based on the network identifier. The at least one processing device is further configured to transmit the data packet to a field device in the field device network. The wireless infrastructure node, the WFN controller, and the field device network comprise one logical WFN among a plurality of logical WFNs. The wireless infrastructure node is one of a plurality of pooled infrastructure nodes configured to communicate between a plurality of WFN controllers and a plurality of field device networks arranged in the plurality of logical WFNs.
