This specification outlines the essential technical requirements for Short-range Radio-communication Devices (SRDs) to function within authorized frequency bands, adhere to specified output power levels, and operate under restricted conditions, as detailed in Table 1.
The specification facilitates the non-exclusive sharing of spectrum by SRDs, employing various technical usage conditions and spectrum access mechanisms like duty cycle, frequency hopping, detect and avoid, adaptive power control, and listen before talk. This flexibility accommodates a range of SRD applications, catering to both specific and non-specific usage scenarios.
SRDs encompass fixed, mobile, or portable stations equipped with radio frequency output connectors and dedicated or integral antennas. Their applications encompass alarms, identification systems, radio-detection, vehicle radar systems, wireless local area networks, remote controls, telecommand, telemetry, and on-site paging systems. These devices may employ diverse modulation types and may include speech applications.
SRDs must adhere to the technical requirements specified in Table 1, with exceptions outlined in Table 2.
This specification update results from a public consultation held in July 2023 and includes the following changes:
- Expansion of RFID allowed bands from 920 – 925 MHz to 917 – 925 MHz (as indicated in Table 1).
- Modification of access conditions for operation in the 5.15-5.25 GHz range from “need not employ DFS” to “need not employ TPC and DFS.”
- Opening of WiFi 6E for operation in the 5.945 – 6.425 GHz range.
- Introduction of mandatory compliance with IEC 62368-1 for equipment designed for use with a voltage rating between 50V and 1000V for AC or between 75V and 1500V for DC, as well as for mobile/wearable devices operating within SRD frequencies, such as tablets and mobile phones.
For additional details regarding these changes, please consult Annex B: Addendum/Corrigendum.
