Machine-to-machine (M2M) technology allows devices to communicate wirelessly without human intervention. M2M has been used since the 1980s for applications like utilities monitoring and has grown with advances in wireless technologies. The global M2M market is projected to reach billions as more consumer and business devices connect to networks. Mobile network operators face challenges in capitalizing on M2M's opportunities due to its different business model compared to traditional mobile services. Operators are investing in M2M platforms, competence centers, and sales teams to develop complete M2M solutions.
