Rapporteur:  Mr. Vasenkari, Petri

The ECC Report 283 considers the compatibility and sharing studies related to the introduction of broadband and narrowband systems in the band 410-430 MHz and in adjacent bands. It is stated that the 400 MHz band is very complex - both in terms of which services already use the bands and on the density of usage by country.
ECC Decision (04)06 decides that Wide Band Digital Land Mobile PMR/PAMR systems in this band shall be with 10 MHz duplex spacing between the transmit frequencies of mobile stations (410-420 MHz) and the transmit frequencies of base stations (420-430 MHz). The same duplex spacing applies to 450 MHz bands.
The band 406.1-410 MHz is allocated to fixed, mobile (except aeronautical) and radio astronomy services on a primary basis. Many countries in Europe have this band registered for radio astronomy service, and administrations are urged to take all practical steps to protect the service from harmful interference. The service involves only passive systems, which are very sensitive. To meet the needs of radio astronomy, there may be a need to limit the unwanted emission levels of the radio transmitters and their use in the vicinity of the radio astronomy observatories. The band is also used for many simplex PMR/PAMR services.
In the band 420-430 MHz there is a secondary allocation to radiolocation service in the majority of European countries, except for the UK where it is allocated on a primary basis. On 430-440 MHz, radiolocation has a primary allocation. 420-450 MHz is the tuning range of airborne and ground radars. This frequency range is harmonised for NATO ground, air and naval military radar systems.
The ECC Report 283 includes sharing studies with new LTE-based systems as aggressors and various other systems as victims, and concludes on required protection distances and unwanted emission masks. The compatibility is considered with narrowband PMR, digital television above 470 MHz, radars (radiolocation), radio astronomy, fixed links, PMSE, paging devices, and short range devices. The study results are used for basis of the regulatory decisions, which are outlined in section 4.2.
