Note 1 Alternatively other mitigation techniques which achieve at least an equivalent level of spectrum compatibility.
Note 2 A network access point in a data network is a fixed terrestrial short range device that acts as a connection point for the other short range devices in the data network to service platforms located outside of that data network. The term data network refers to several short range devices, including the network access point, as network components and to the wireless connections between them.
Note 3 In some countries, usage may be limited such that installation and operation are performed only by professional users and individual authorisation may be required, e.g. to administer geographical sharing and/or the application of mitigation techniques to ensure protection of radio services. Individual authorisation or additional mitigation techniques (e.g. LBT) may also be applied to NAP in areas with a high number of NAP.
Note 4 Transmissions only permitted within the frequency ranges 865.6-865.8 MHz, 866.2-866.4 MHz, 866.8-867.0 MHz and 867.4-867.6 MHz.
Note 5 Existing implementations in some countries include frequencies up to 875.6 MHz. See explanations under frequency issues for sub-bands c2) to c4).
Note 6 Transmissions only permitted within the frequency ranges 917.3-917.7 MHz and 918.5-918.9 MHz.
Note 7 DFS is required in the frequency range 5725-5850 MHz to ensure an appropriate protection to the radiolocation service (including frequency hopping radars), DAA is required in the frequency range 5855-5875 MHz for the protection of ITS, in the frequency range 5725-5875 MHz for the protection of BFWA, and in the frequency range 5795-5815 MHz for the protection of TTT applications

Frequency issues
Sub-bands c2) to c4): Use of all or part of sub-bands c2) to c4) may be limited or not authorised for SRD in data networks in some countries where the sub-bands are used for defence / governmental systems. Further, some countries use the sub-bands 873-876 MHz and 918-921 MHz as extended GSM-R frequency bands; therefore geographical restrictions may apply. CEPT is considering a harmonised spectrum regulatory framework for the future railway mobile communications systems in 874.4-880 / 919.4-925 MHz and these frequency bands may require a review regarding their use in the future. Some countries have existing implementations for SRD in data networks in the frequency range 874.4-875.6 MHz. Appendixes 1 and 3 provide the status of national implementations. CEPT administrations should provide information on any more restrictive or more relaxed national measures to ensure Appendixes 1 and 3 are up to date. EC Decision 2018/1538/EU applies to EU Member States. CEPT administrations should refrain from introducing new SRD uses in 874.4-876 MHz and 919.4-921 MHz. It is recognised that, in several CEPT countries, existing implementations in these frequency ranges are not impacted by Article 3(4) of the EC Decision. National rules, such as local coordination, may also be needed in order to avoid interference to radio services operating in the adjacent bands. With regard to sub-band c2), the frequency range 874-874.4 MHz is the European harmonised minimum core band according to EC Decision 2018/1538/EU. With regard to sub-band c4), the frequency range 917.4-919.4 MHz is the European harmonised minimum core band according to EC Decision 2018/1538/EU.
