The 2016 CAUSE IV experiment between the United States and Canada will be held April 26-28, 2016, at the Blue Water Bridge, the second busiest crossing between the U.S. and Canada, along the border of Michigan and Ontario.

Following the successes of CAUSE III, which occurred in fall 2014, the CAUSE IV experiment aims to act as a catalyst for building relationships in support of the U.S.-Canadian Beyond the Border Action Plan. The objectives of the CAUSE series are to explore how to build a binational communications interoperability capability and to connect, test and demonstrate emerging operational technologies available between the two countries.
