This work item concerns the definition of a reliable spectrum framework and the assessment of feasibility with the primary focus on the following bands, whilst ensuring compatibility with radio services and incumbent systems.
 
- the commercial use of command and control systems by UAS in the 1900-1920 MHz and 5000-5010 MHz bands.
- The governmental use of command and control as well as payload systems by UAS in the 1880-1900 MHz and 1900-1920 MHz bands.

U-space related systems on-board the UAS should be taken into account as far as possible.

The UAS to be studied fall in the “Open” and “Specific” categories as identified in ECC Report 268.5000-5010 MHz could be used by “Specific ” category UAS which do not require the use of specified aeronautical solutions for CC. 

Other bands may also be considered depending on the progress of work.

Governmental use does not address military usage (national matter).
