The need for an ECC Report to be developed by WGFM may be considered at later stage, while the technical studies are to be done with a view that, based on the related conclusions, a harmonisation measure could be developed possibly as an ECC Decision and/or Recommendation.
This work should not introduce any changes to the existing regulations for LPI and VLP in 5945-6425 MHz.
The work should consider the current availability of equipment up to 4W e.i.r.p. and the benefits associated with aligning the technical regulations in other Regions outside Europe.
Supporting studies from WG SE will provide technical conditions to enable the implementation of a dynamic spectrum usage coordination function including the possible use of WAS/RLAN equipment up to 4 W e.i.r.p. to operate and coexist with existing services in the 5945-6425 MHz frequency band(FS, FSS) and in adjacent bands (RAS, CBTC, Road ITS), while ensuring the protection of those services. Specifically, the protection of the FSS, taking into account the aggregate effects of the additional terrestrial use, has to be ensured. This work should be based on the conclusions of ECC Report 302 as a starting point. RLAN to RLAN studies are not considered part of the scope of this WI.
The database(s)management will need to be addressed, including the questions regarding implementation, regulatory and technical conditions of those databases, as well as the question how the required functionality and performance when implemented in a device can be ensured. The work should also take noteof the previous work carried out in ECC Report 236 on implementation of databases.
Exchanges with ETSI will be necessary concerning the implementation of a dynamic spectrum access coordination, i.e. standard communication interfaces and database management framework.
