To study and assess compatibility and coexistence scenarios both for (i)
terrestrial systems capable of providing WBB ECS and (ii) WAS/RLANs, with
identified existing usages (e.g. FSS, FS, EESS (passive), RAS) in the 6425-7125
MHz frequency band and existing usages (e.g. FSS, FS and WAS/RLAN below 6425
MHz) in adjacent band(s) and their potential evolution, and identify
coexistence parameters and conditions to be implemented in the regulatory
framework in order to enable such possible coexistence, without constraining
relevant (Note 1) incumbent users in various Member States within and adjacent to the
6425-7125 MHz band, including at the EU’s external border.
-----------------------------
Note 1: "Relevant” denotes incumbent services/applications with long-term usage
perspective and coexistence requirements, in line with the international and
EU-level regulatory framework (e.g. FSS, FS, EESS (passive), RAS).
-----------------------------
For each compatibility/coexistence scenario, the risk of interference,
the deployment assumptions of relevant applications, the geographical extent of
usage and any consequential restrictions in deployment of those two systems
should be identified as well as requirements for implementing such scenarios,
for instance in terms of harmonised least restrictive technical conditions or
in terms of other regulatory and operational aspects which support the
implementation of a coexistence framework.
This task should also consider available conclusions for coexistence
with incumbent radiocommunication services, such as the outcomes of the WRC-23
and technical studies performed by the CEPT and the ITU-R.
