CatalyX® is Anterix's first Active Ecosystem Platform commercial solution that can accelerate utility adoption of 900 MHz private LTE.
As today’s grid evolves to increase resiliency, support DER integration, and meet decarbonization goals, 900 MHz Private LTE delivers the security, control and performance for utilities to deliver clean and affordable energy safely. An important aspect of wireless broadband deployment is supporting a wide array of fixed grid endpoints and mobile devices. With the increased proliferation of connected sensors and intelligent grid devices, utilities need a solution that integrates all aspects of connectivity management, making it simple, flexible, and secure.
What Is CatalyX?
CatalyX is a turnkey connectivity management solution that helps utilities realize the benefits of private broadband networks, while leveraging commercial broadband. CatalyX simplifies connectivity management by integrating state-of-the-art SIM technology, device SIM management, and private to public roaming to deliver the flexibility and security that utilities require.
CatalyX integrates state-of-the-art SIM/eSIM management technology from Giesecke+Devrient (G+D), the market leader in eSIM management solutions. G+D supplied the world’s first commercial SIM card and successfully deployed the first eSIM management platform. Their technology enables the security and reliability of connections to global mobile networks. As of 2024, G+D was actively managing millions of eSIMs, had deployed hundreds of SIM management solutions for leading service providers and device manufacturers worldwide, and is managing over 3 billion SIM cards. Anterix’s collaboration with this renowned technology leader in security and identity enhances CatalyX’s capabilities.
Utilities can now efficiently and securely deploy and manage smart grid devices on a private network while optimizing broadband coverage in their service territories. CatalyX provides control and visibility of devices, whether they are connected to the private or public radio access network. With CatalyX, utilities can manage each device SIM remotely, which can reduce operational costs and risks. Through a single dashboard, all aspects of device connectivity can be monitored and managed including connecting to both public and private networks. Utilities can achieve available coverage at service locations, by connecting to the private LTE network, and roaming on multiple commercial carrier networks.
How Can CatalyX Help Utilities?
CatalyX supports utilities in their private LTE journey by:
- accelerating onboarding of devices during the network deployment,
- extending the private network coverage in gap areas and,
- providing back-up connectivity during private network downtime. From their private LTE network, utilities can seamlessly connect devices to commercial networks for primary coverage or as a fallback, helping them achieve the network coverage and resiliency that is required for mission critical grid applications.
CatalyX is the first of many applications as part of the Anterix Active Ecosystem platform. Working collectively with our Utility Strategic Advisory Board (USAB), Anterix continues to identify requirements for the utility industry to enable a broader suite of applications.

CatalyX Value to Utilities
Supports immediate deployment of devices on private networks that use commercial coverage until the private LTE network is built out
Streamlines operations with its Cloud based solution that activates and remotely provisions devices, manages subscriber access, authentication, and configuration
Simplifies management with its web-based dashboards and reporting portal and APIs for bulk transactions and integration
Supports zero touch transition from public to private coverage with state-of-the-art SIM technology, connecting devices to commercial coverage first and private LTE coverage when ready
Eliminates the need for truck rolls for connectivity reconfiguration with the added benefit of redundant connectivity for the life of the asset.
Provides access to available commercial connections across utility service areas, enabling customized roaming plans—ability to change cellular provider over the lifecycle of the device without changing the physical SIM
Enables seamless evolution to private LTE, providing a private core that connects to commercial RAN with easy transition to utility owned private core and RAN
Accelerates the transition to a 900 MHz private LTE network and device deployments, simplifying transition and helping to mitigate cost and risks
Employs multiple layers of security at every level of the solution including device endpoints, network, and platform
