ENVELOPE 2nd Open Call

ENVELOPE 2nd Open Call

19 November 2025

After their first Open Call earlier this year, the EC project ENVELOPE has launch its second call for proposals that will validate network exposure and programmability as an accelerator for the development and deployment of 5G-enabled CAM services (and beyond). A series of northbound standards-compliant i.e., LF CAMARA, ETSI MEC, APIs (and corresponding technical enablers) implemented in three European trial sites, provide a unique experimentation environment for applicants to realize the interaction of their applications with the B5G network, test in the field, and ultimately validate the associated benefits, while avoiding the complexity of direct interaction with the B5G core.

The candidate projects shall:

  1. make use of at least 1 API and technology enabler developed by the ENVELOPE Consortium; and/or
  2. design, develop, integrate and validate a new standards compliant API/technical enabler, extending this way the functionality of the ENVELOPE platform.

In doing so, the projects must:

  1. demonstrate the associated benefits in development, deployment and performance of a novel CAM vertical service; and/or
  2. enhance the impact of the ENVELOPE platform by contributing to the range of use cases that can be supported and the ecosystem that can be created.

Moreover, proposals must focus on the impact of the candidate project after its completion and implementation. Proposals with concrete business plans leading to mature solutions will be prioritized.
