December 06, 2020

According to Regulation 9 of the Radiocommunications Regulations, 2001 made under section 116(1)(b) of the Radiocommunications Act 1989 (“Act”), and acting under delegated authority. This notice is the Radiocommunications Regulations Notice 2020 and came into force in November 2020.

Special conditions:

-Use is limited to wireless power transfer systems and induction loop systems used for the detection of foreign objections.

-Use is limited to wireless LAN.

-Use is limited to road transport and traffic telematics.

-Use is limited to field disturbance sensors.

-Use is limited to RFID systems.

-Transmitters using e.i.r.p. greater than 0 dBW (1 W) must employ frequency hopping or digital modulation techniques.

-In the band 405 – 406 MHz, the maximum permitted duty cycle is 0.1%.

-In the band 868 – 870 MHz, the maximum power is -27 dBW (2 mW) e.i.r.p. and the maximum permitted duty cycle is 1%, except in the band 869.20 – 869.25 MHz, where the maximum power is –20 dBW (10 mW) e.i.r.p. and the maximum permitted duty cycle is 0.1%.

-In the band 5150 – 5350 MHz, the maximum power is 0 dBW (1 W) e.i.r.p. and the maximum permitted power spectral density is –13 dBW/MHz (50 mW/MHz) e.i.r.p., provided Dynamic Frequency Selection and Transmitter Power Control are implemented in conjunction with the following vertical radiation angle mask where θ is the angle above the local horizontal plane (of the Earth):

-In the band 5470 – 5725 MHz, the transmitter peak power must not exceed -6 dBW (250 mW). The maximum power is 0 dBW (1 W) e.i.r.p. and the maximum permitted power spectral density is -13 dBW/MHz (50 mW/MHz) e.i.r.p., provided Dynamic Frequency Selection and Transmitter Power Control are implemented. If Transmitter Power Control is not used, then the maximum power (e.i.r.p.) value must be reduced by 3 dB.

-In the band 7.4 – 8.8 MHz, use is restricted to inductive systems where the magnetic field strength from devices must not exceed 9 dBµA/m at a distance of 10 meters.

-In the band 3.155 – 3.400 MHz, the maximum permitted field strength is 13.5 dBµA/m measured in a 10 kHz bandwidth at a distance of 10 metres. In the bands 3.64 – 4.04 MHz and 10.44 – 10.76 MHz, the maximum permitted field strengths are -15 dBµA/m and -20 dBµA/m, respectively, both measured in a 10 kHz bandwidth at 10 meters.

– In the band 0.1485 – 30 MHz, the magnetic field strength from devices must not exceed -15 dBμA/m measured in a 10 kHz bandwidth at a distance of 10 metres, and the magnetic field strength must also not exceed -15.5 dBμA/m while within the frequency range 0.521-1.612 MHz. Users should not to operate these devices within 3 meters of an AM radio receiver intended for the reception of AM radio broadcasts within the frequency range 0.521 – 1.612 MHz.

– Indoor-Only Systems: In the band 57 – 66 GHz, the power spectral density must not exceed -17 dBW/MHz (20 mW/MHz) e.i.r.p.

– Transmissions must not exceed the following unwanted emission limits: -79 dBW (-49 dBm) e.i.r.p. within 800 – 915 MHz and -63 dBW (-33 dBm) e.i.r.p. within 928 MHz – 1 GHz. The reference bandwidth for emissions is 100 kHz. Outside the band 800 MHz – 1 GHz, the limits prescribed in applicable standards prescribed in the Radiocommunications (Radio Standards) Notice 2020* apply. In the absence of applicable standards, the limits prescribed in Table 2 of the notice apply.

-Use is limited to the purpose known as wireless microphones, in-ear monitors, or wireless audio transmitters.

– In the band 0.009 – 0.090 MHz, the magnetic field strength from devices must not exceed 72 dBµA/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 dBµA/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 dBµA/m at a distance of 10 metres. In the band 0.315 – 0.430 MHz, the magnetic field strength from devices must not exceed -5 dBµA/m at a distance of 10 meters.

-Analogue modulation schemes are permitted with a maximum necessary bandwidth of 300 kHz. Digital modulation schemes are permitted with a maximum necessary bandwidth of 200 kHz. Use of a power level above –20 dBW is only permitted when the user has first determined that the intended use will not affect the reception of television broadcasts in or adjacent to the proposed area of operation.

– Use is limited to radiodetermination transmitters operated within shielded enclosures and installations must be inside the shielded enclosure. The maximum power -54 dBW e.i.r.p. applies at 3 metres as measured outside the shielded enclosure over a maximum of 50 MHz bandwidth. The emission leakage outside the shielded enclosure must not exceed the maximum permitted power spectral density -71.3 dBW/MHz (-41.3 dBm/MHz) e.i.r.p. at any time.

– In the band 5725 – 5850 MHz, the transmitter peak power must not exceed 0 dBW (1 W) and the power spectral density must not exceed 17 dBm/MHz. The maximum power of any emission must not exceed 23 dBW (e.i.r.p.). Transmission is permitted from customer premise equipment with integrated antenna that is part of a point-to-multipoint system receiving from and transmitting to a central access point.

– Emission of the transmitter needs to comply with below block edge mask (BEM). Maximum e.i.r.p. of -17 dBW per channel for handheld unit and -13 dBW per channel for body-worn unit. The spectrum will be available from 1 April 2021.

General conditions applying to all transmissions under this license:

1. The frequency ranges, the peak power of transmissions within those frequency ranges, and designated uses of frequencies are those prescribed in this licence. All transmissions in a given frequency range must comply with any special conditions relating to that frequency range.

2. Transmitters, and persons supplying or using transmitters, must comply with the requirements of Regulations 32 – 37 of the Radiocommunications Regulations 2001.

3. Frequency use is on a shared basis and the chief executive does not accept liability under any circumstances for any loss or damage of any kind occasioned by the unavailability of frequencies or interference to the reception.

4. Should interference occur to services licensed pursuant to a radio licence or a spectrum licence, the chief executive reserves the right to require and ensure that any transmission or any emission pursuant to this General User Radio Licence change frequency, reduce power, or cease operation.

5. Transmissions that are broadcasting, as defined in the Broadcasting Act 1989, are not permitted.
