The Grand Paris Metro Project is an extensive metro expansion project for the city of Paris. According to the Société du Grand Paris, the Grand Paris Express is the new metro of the Capital region that will provide connections to developing neighborhoods, Paris’ 3 airports, business districts and research clusters. It will service 165,000 companies and transport 2 million commuters daily thus creating new opportunities for economic development.
The project needed data nodes that could gather data from sensors installed up to seven basement levels deep in selected buildings. The data nodes had to be compatible with different types of sensors and had to require minimal manual maintenance for the replacement of the batteries.
