Die Annotation des Normtextes ČSN ETSI EN 303204-V3.1.1 (875171):
V3.1.1 The present document specifies technical characteristics and methods of measurements for the following types of equipment: - Type 1 equipment: SRDs in data networks: - Type 1a: Terminal nodes - Type 1b: Network nodes - Type 1c: Network access points Type 1a terminal nodes and type 1b network nodes are fixed SRDs, operating up to 500 mW e.r.p. and with adaptive power control, which are intended to operate in association with other SRDs to form data network topologies supporting the intended application. Type 1c network access points are specific fixed SRDs, operating up to 500 mW e.r.p. and with adaptive power control, supporting interconnection of a network of SRDs with an external network or service. These radio equipment types are capable of operating in all or part of the relevant frequency bands given in Table 1. NOTE 1: 874,0 MHz - 874,4 MHz is a harmonised core band according to EC Decision 2018/1538 [i.3]. NOTE 2: The availability of the frequency bands in Table 1 in European Union and CEPT countries can be obtained from the EFIS ( and is also listed in Appendices 1 and 3 of CEPT/ERC/REC 70 03 [i.2]. NOTE 3: In addition, it should be noted that, in some countries, part or all of the bands in Table 1 may be unavailable, and/or other frequency bands may be available, for networked and/or network based short range devices. See National Radio Interfaces (NRI) as relevant for additional guidance. NOTE 4: On non-harmonized parameters, national administrations may impose certain conditions such as the type of modulation, frequency, channel/frequency separations, maximum transmitter radiated power, duty cycle, installation and operation only by professional users and the inclusion of an automatic transmitter shut-off facility, as a condition for the issue of Individual Rights for use of spectrum or General Authorization, or as a condition for use under "licence exemption" as it is in most cases for Short Range Devices. The present document covers equipment intended for use in a fixed location. The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. NOTE 5: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU [i.1] is given in Annex A
