The corridor that is subject to the study must cross at least one border between two Member States.

The corridors that are subject to the study should meet the following requirements:

• The infrastructure under study should deliver uninterrupted coverage over the whole range of the corridor section thus ensuring high-quality connectivity – depending on the expected traffic demand along the different parts of the section – suitable to provide a broad range of 5G and, where appropriate (i.e. focusing on hotspots e.g. traffic junctions, roadworks, etc.), complementary safety-related services based on existing direct short range communication technologies, such as 4G LTE-V2X and ITS-G5, compatible with existing deployment and supporting complementarity between existing and future infrastructure deployments.
• The corridor under the study should be capable of meeting service requirements for both safety-related road/rail/waterway operations (e.g. Intelligent Transport Systems (ITS), Future Rail Mobile Communication System (FRMCS), River Information Services (RIS) and multi-service/multi-application 5G services and ensure business continuity across the entire section of the corridor, including in a cross-border environment. The infrastructure can be used for services beyond the transport paths under certain conditions, e.g. in areas surrounding the corridor including populated areas or socio-economic drivers where market failure is demonstrated, without causing undue competition distortions or crowding out effects and provided third party open wholesale access under fair, reasonable and non-discriminatory condition is provided.
• The infrastructure under study should make use of at least one 5G pioneer band (700 MHz, 3.6 GHz, 26 GHz) and if appropriate the 5.9 GHz ITS band and the 900 MHz and 1900 MHz FRMCS bands. If 5G radio-communication technologies are used along the corridor, they should be based on the latest suitable 5G specifications made available by 3GPP, and furthermore be able to integrate upgrades when available. The infrastructure should support advanced service features such as quality of service guarantees enabled by 5G edge computing facilities and facilities allowing for 5G network slicing. etc. (p. 14-15 of the call document)

Cross-border sections that are complementary to national 5G corridor sections already planned for deployment by the private sector or identified under RRF or other national programmes in line with state aid rules are particularly encouraged in view of their additional potential impact at an early stage.
