Wireless mesh networks are still a current topic even over twenty years from their first inroads to market success. Until recently, there have been too many trade-offs and limitations exist in latency, hop count limits, determinism, and reliability through all the globally supported wireless mesh networking technologies. The reason is simple: technical criteria focused primarily on routing optimization rather than reliability. Contrary to that approach, the IQRF has focused on reliable message delivery as the primary criterion. With 250+ routing hops and reliable message delivery, the IQRF excels nowadays, especially in street lighting applications, where a long range is required, and high reliability must be guaranteed.
