ANNEX 1: NON-SPECIFIC SHORT RANGE DEVICES

Scope of annex
This annex covers frequency bands and regulatory as well as informative parameters valid for all types of applications and also recommended primarily for Telemetry, Telecommand, Alarms and Data in general and other similar applications. Video applications should be preferably used above 2.4 GHz. This annex also includes references to the generic UWB regulation which was primarily developed to allow communication applications using UWB technology in bands below 10.6 GHz; but enables also other types of radio applications.

Note 1 The duty cycle applies to the entire transmission (not to each hop channel).
Note 2 Frequency bands for alarms (see Annex 7) are excluded.
Note 3 Voice applications are allowed with a maximum bandwidth of 25 kHz, with a spectrum access technique such as LBT or equivalent and a maximum transmit period of 1 minute for each transmission. Other audio/video applications are excluded.
Note 4 These limits should be measured with an rms detector and an averaging time of 1 ms or less.
Note 5 The available channel centre frequencies are 916.3 MHz, 917.5 MHz, and 918.7 MHz. The channel bandwidth is 400 kHz.
Note 6 Existing implementations in some countries include frequencies up to 876 MHz. See explanations under frequency issues for sub-bands h2) and h3).
Note 7 Existing implementations in some countries include frequencies up to 921 MHz. A fourth 100 mW e.r.p./400 kHz channel at centre frequency 919.9 MHz may be implemented. See explanations under frequency issues for sub-bands h2) and h3).

Frequency issues
The bands in Annex 1 a), b), c1) to c5), d), g1) to g3), i), j), m), n1), n2), o1), o2), p) are also designated for industrial, scientific and medical (ISM) applications as defined in ITU Radio Regulations. Sub-band h0): SRD vendors wishing to use the band 862-863 MHz should weigh the risk and accept responsibility for deciding themselves whether their specific applications shall be capable of operating in the presence of comparatively high ambient noise levels from out-of-band emissions of MFCN terminals and design their products accordingly. Sub-bands h1.0) to h1.2) and h1.4): Certain channels may be occupied by RFID interrogators transmitting at higher powers than SRD (see Annex 11). To minimise the risk of interference from RFID, SRD should use LBT with AFA or observe suitable separation distances. In the high power RFID interrogator channels, these may vary from 918 m (indoor) to 3.6 km (rural outdoor). In the remaining 2.2 MHz, where tags at -20 dBm e.r.p. occupy the spectrum, this may vary from 24 m (indoor) to 58 m (rural outdoor). The adjacent frequency bands below 862 MHz and above 870 MHz may be occupied by systems using high transmission power. SRD manufacturers should take this into account in the design of equipment; choice of frequency bands and power levels. Sub-bands h2) and h3): Use of all or part of sub-bands h2) and h3) may be limited or not authorised for non-specific SRD 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, and therefore access to the frequency bands 873-876 / 918-921 MHz by non-specific SRD applications may require additional interference mitigation measures to be implemented such as transmission timing limitations, as set out in ECC Report 200. CEPT considers a harmonised spectrum regulatory framework for the future railway mobile communications systems in 874.4-880 MHz and 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 the frequency ranges 874.4-876 MHz and 919.4-921 MHz. Appendixes 1 and 3 provide the status of national implementations. It is important that CEPT administrations 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. CEPT administrations wishing to implement new provisions for SRD are encouraged to consider national alignment with the technical conditions for SRD in data networks, as set out in Decision 2018/1538/EU, where all devices within the data network shall be under the control of a network access point (see Annex 2). National rules, such as local coordination, may also be needed in order to avoid interference to radio services operating in the adjacent bands.
