HG data projects that $76.1 billion will be spent on the global Internet of Things (IoT) market over the next 12 months. IoT devices are physical objects that are inserted with software or other mechanisms that allow them to communicate autonomously over the internet.
Because these IoT systems and devices can communicate without human intervention, the implications for business innovation and operational efficiency are seemingly endless, as are the use cases – from smart homes to smart cities and everything in between.
HG’s comprehensive view of the IoT market leverages proprietary insights from our Market Intelligence platform. This report offers an in-depth Internet of Things market analysis into global spending trends, leading IoT vendors, and buyer profiles.
