One of the key areas of development for next-generation wireless technology is IoT, the Internet Of Things. To date, a lot of attention is paid to the myriad of use cases for IoT, and the technologies that can be enable them. But very little attention is given to the actual business case for deploying IoT networks, either for an IoT network operator or for the enterprise end-user. This lack of hard financial analysis has led to the deployment of many Proof of Concept (PoC) IoT projects, but very few production network deployments. Wireless 20/20 has developed the WiROI™ IoT Business Case Tool to help optimize business case development to ensure more economically successful IoT applications and network deployments.
