SRD frequencies. License-free frequency ranges. Glossary of terms and abbreviations in radio communications



Short Range Devices (SRD) include remote control equipment and telemetry transmission devices, telecontrol, alarm systems, data transmission, and other similar transmissions. The use of frequency resources by short range devices is regulated by the EN 300 220 standard and ITU-R Recommendation SM.2153-2. In Russia, the allocation of frequency resources for SRD devices is regulated by the State Commission for Radio Frequencies (SCRF) Decision dated 07.05.2007 No. 07-20-03-001 with amendments and additions:
— as per the appendix to the decision dated 28.04.2008 No. 08-24-01-001;
— by decision dated 20.12.2011 No. 11-13-07-1;
— by the appendix to protocol No. 14-26 dated 22.07.2014;
— by the appendix to the decision dated 11.09.2018 No. 18-46-03-1;
— by the appendix to the decision dated 13.07.2020 No. 20-55-06-1.

1 — According to the Appendix to the list of radio-electronic equipment and high-frequency devices subject to registration, approved by Russian Government Resolution No. 1800 of 20.10.2021, terminal non-specialized devices with a maximum effective radiated power of 25 mW are not subject to state registration. At the same time, the use of base stations in communication networks for collecting and processing telematic information is permitted provided that the base stations are registered in accordance with the Rules for registration of radio-electronic equipment and high-frequency devices, approved by Russian Government Resolution No. 1800 of 20.10.2021. In addition, since 01.12.2020, the condition for building Internet of Things (IoT) networks and transport telematics in the 860 MHz range is the use of base stations manufactured in Russia, which have been granted the status of telecommunications equipment of Russian origin (TORP). This requirement does not apply to base stations registered before 01.12.2021 (SCRF meeting protocol of 28.12.2020 No. 20-57).

2 — In the range 433.075 – 434.750 MHz, Russian Government Resolution No. 1800 of 20.10.2021 also allows the use of unregistered low-power portable radios in the Mobile Radio Service range with transmitter output power not exceeding 10 mW.

3 — The range is used by radio modems for telemetry transmission, for example Guardian 100/400.

4 — The procedure for using the frequency range by ultra-wideband (UWB) short range wireless devices, which use a radio channel at least 500 MHz wide for transmission and/or reception of data, is regulated separately by the Appendix to the SCRF Decision dated 15.12.2009 No. 09-05-02.
