The Generic Object Oriented Substation Event (GOOSE) protocol is a communication model that is defined by the International Electrotechnical Commission (IEC) 61850 standard which supports the sharing of time-critical information between Intelligent Electronic Devices (IEDs) within a substation. Due to strict requirements, GOOSE demands a fast, reliable, and deterministic network, which today is based on Ethernet networking technologies. Customers desire an alternative solution that is based on wireless radio technologies such as, for example, mesh-based networks. However, for a variety of reasons, it can be challenging to implement GOOSE over a wireless medium. Techniques are presented herein that support a reliable wireless solution for time-critical communication facilities such as GOOSE. Aspects of the presented techniques encompass using several radios coupled with an intelligent assignment of radio channels to avoid interference and employing duplication over such radios to carry critical information between IEDs. Use of the presented techniques yields an important level of determinism that allows critical information (such as GOOSE type 1A messages) to be carried over a wireless medium.
