Radio Spectrum Management has started a consultation on adding new usages to the General User Radio License – Short Range Devices. This concerns uses below 30 MHz for:
- Wireless power transfer systems
- Inductive loop systems
RSM have proposed the following changes to the GURL SRD:
| Proposed modifications to existing provisions within 0.009 – 0.205 MHz | ||||
| Low (MHz) | High (MHz) | Reference Frequency (MHz) |
Maximum Power dBW e.i.r.p. |
Remarks |
| 0.0090 | 0.0900 | 0.0495 | 9.0 | RETAIN special conditions 1 and 25ADD special condition New_1 |
| 0.0900 | 0.2050 | 0.1475 | -20.0 | |
| 0.1190 | 0.1350 | 0.1270 | 3.0 | |
| Proposed new provision for 0.1485 – 30 MHz | ||||
| Low (MHz) | High (MHz) | Reference Frequency (MHz) |
Maximum Power dBW e.i.r.p. |
Remarks |
| 0.1485 | 30.0000 | 14.92575 | -56.0 | ADD special conditions
New 2 and New 3 |
| Special Conditions:
1. Use is limited to determination, telemetry or telecommand. 25. In the band 0.009- 0.090 MHz, the magnetic field strength from devices must not exceed 72 dBpA/m at a distance of 10 metres. In the band 0.090-0.205 MHz, the magnetic field strength from devices must not exceed 43 dBpA/m at a distance of 10 metres, except in the band 0.119-0.135 MHz, where the magnetic field strength from devices must not exceed 66 dBpA/m at a distance of 10 metres. In the band 0.3150-0.430 MHz, the magnetic field strength from devices must not exceed -5 dBpA/m at a distance of 10 metres. New_1 Transmissions are permitted for wireless power transfer systems. New_2 Transmissions are permitted for inductive loop systems. New_3 In the band 0.1485-30.000 MHz, the magnetic field strength from devices must not exceed -15 dBpA/m measured in a 10 kHz bandwidth at a distance of 10 metres. User is also encouraged not to operate these devices within 10 metres of an AM radio intended for the reception of AM radio broadcasts, wherever practicable. |

In conjunction with the proposed changes to GURL SRD, RSM also propose to add the two international standards ETSI EN 303 417 (V1.1.1) and ETSI EN 300 330 (V2.1.1) as the applicable standards for WPT and inductive loop systems in an updated version of Radio Standards Notice.
The consultation is open for comments until 14 September 2018, and full details can be found here.
