The rise in industrial automation is expected to drive the growth of the serial to cellular gateway market going forward. Industrial automation involves the use of control systems, robots, and information technologies to operate machinery and processes in manufacturing and other industries with minimal human intervention. It is increasing due to the growing need for higher productivity and operational efficiency in manufacturing. Serial to cellular gateways are used in industrial automation to enable remote monitoring and control of serial-based equipment over cellular networks. For instance, in September 2024, according to the International Federation of Robotics (IFR), a Germany-based non-profit organization, industrial robot installations in the UK increased by 51%, reaching 3,830 units, while in the Americas, over 50,000 units were installed for the third consecutive year, totaling 55,389 units in 2023. Therefore, the rise in industrial automation is propelling the growth of the serial to cellular gateway market.

Key companies operating in the serial to cellular gateway market are focusing on developing advanced, secure, and globally compatible connectivity solutions with integrated edge intelligence to enhance remote device management, improve data processing efficiency, and support diverse industrial IoT applications. Edge intelligence refers to the capability of devices at the network edge to process data, make decisions, and perform analytics locally without relying on a centralized cloud system. For instance, in October 2025, Digi International, a US-based telecommunication company, launched the Digi XBee 3 Global LTE Cat 4 cellular modem, expanding its XBee portfolio to support high-bandwidth IoT applications such as smart agriculture, energy, and industrial automation. The modem offers global LTE Cat 4 connectivity with 2G/3G fallback, GNSS for location tracking, Bluetooth Low Energy for sensor integration, and compatibility with major IoT platforms such as AWS and Azure. Featuring an integrated MicroPython environment for edge intelligence, it enables local data processing and decision-making. With pre-certifications, enhanced security via Digi TrustFence, and centralized remote management through Digi Remote Manager, it simplifies IoT deployment and ensures reliable, scalable connectivity worldwide.
