2. General user radio licence

A general user radio licence is granted for the transmission of radio waves using Short Range Devices (SRD), also known as Restricted Radiation Devices (RRD), Low Interference Potential Devices (LIPD), or Spread Spectrum Devices (SSD), in accordance with the terms, conditions and restrictions of this notice.

3. Terms, conditions and restrictions

1. The frequency ranges, peak power of transmissions within those frequency ranges, and designated uses of frequencies are those prescribed in the Schedules to this notice. All transmissions in a given frequency range must comply with the notes in the Schedule relating to that frequency range.
2. Transmitters must conform to technical standards as prescribed in notices made under Regulation 32(1)(b) of the Regulations.
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 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 pursuant to this General User Radio Licence change frequency, reduce power, or cease operation.
5. Transmissions for the purposes of broadcasting, as defined in the Broadcasting Act 1989, are not permitted.
    

4. Transitional provisions

Transmissions authorised under the General User Radio Licence for Short Range Devices Notice 2007, dated the 5th day of April 2007 and published in the New Zealand Gazette, 5 April 2007, No. 39, page 958, which are not authorised under other provisions of this notice are permitted to continue until 12 August 2010 and must cease thereafter.

5. Consequential revocation of licences

1. The Radiocommunications Regulations (General User Radio Licence for Short Range Devices) Notice 2010, dated the 12th day of July 2010 and published in the New Zealand Gazette, 15 July 2010, No. 83, page 2272, is revoked.
2. Notwithstanding the revocation of the notice under subsection (1), subject to section 4 every transmitter capable of making transmissions compliant with the requirements of that notice on the commencement date of this notice is deemed to be compliant with the requirements of this notice.

Schedule 2

Notes to Schedules

Note 1: In the band 0.009 to 0.03 MHz the maximum permitted field strength is 2400/f(kHz) µV/m measured using an average detector at 300 metres.

Note 2: Transmitters employing frequency hopping or digital modulation techniques in the bands 864 to 868 MHz, 921.5 to 928 MHz, 2.4 to 2.4835 GHz and 5.725 to 5.875 GHz may operate with gain antennas provided the peak power does not exceed 4 W e.i.r.p. Transmissions from devices operating in accordance with this note and in the band 921.5 to 928 MHz must not exceed the following limits: –49 dBm at 915 MHz to –36 dBm at 921.5 MHz, and –46 dBm above 928 MHz. The unwanted emission limits applicable to frequencies within the range 915 MHz to 921.5 MHz are to be determined in accordance with the formula y = mx + C, where–, y = dBm, x = MHz, m = dy/dx, C = the value of y where x = 0 (the y intercept). Measurements are to be completed using a 100 kHz reference bandwidth.

Note 3: In the band 402 to 406 MHz the maximum permitted duty cycle is 0.1%.

Note 4: In the band 868 to 870 MHz, the maximum permitted duty cycle is 1%, except as follows: in the band 869.2 to 869.25 MHz, a peak power of 10 mW is permitted, and the maximum permitted duty cycle is 0.1% for devices exceeding 2 mW peak power in this band.

Note 5: In the band 5150 to 5250 MHz, the maximum permitted power density is 10 mW/MHz e.i.r.p. or equivalently 0.25 mW/25 kHz e.i.r.p.

Note 6: Indoor-Only Systems: In the band 5250 to 5350 MHz, the maximum permitted mean power is 200 mW e.i.r.p. and the maximum permitted mean power density is 10 mW/MHz e.i.r.p., provided Dynamic Frequency Selection and Transmitter Power Control are implemented. If Transmitter Power Control is not in use, then the e.i.r.p. values shall be reduced by 3 dB;

Indoor and Outdoor Systems: In the band 5250 to 5350 MHz, the maximum permitted mean power is 1 W e.i.r.p. and the maximum permitted mean power density is 50 mW/MHz, 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):

Note 7: In the band 5470 to 5725 MHz, the maximum transmitter power is 250 mW with a maximum permitted mean power of 1 W e.i.r.p. and a maximum permitted mean power density of 50 mW/MHz e.i.r.p., provided Dynamic Frequency Selection and Transmitter Power Control are implemented. If Transmitter Power Control is not in use, then the maximum permitted mean power shall be reduced by 3 dB.

Note 8: In the band 57 to 64 GHz, the average power density of any emission, measured during the transmit interval, shall not exceed 9µW/cm2 at a distance of 3 metres and the peak power density of any emission shall not exceed 18µW/cm2 at a distance of 3 metres. 

In the band 57 to 64 GHz, the peak total transmitter power shall not exceed 500 mW.
In the band 57 to 64 GHz, for emissions of bandwidths less than 100 MHz, the transmitter peak power must be limited to 500 mW x (bandwidth (MHz) / 100 (MHz)).

Note 9: In the bands 3.64 to 4.04 MHz and 10.44 to 10.76 MHz, the maximum permitted field strength is -40 dBµA/m measured in a 10 kHz bandwidth at 10 metres.

Explanatory Note

This note is not part of the notice, but is intended to indicate its general effect.
This notice:

1. specifies a maximum permitted duty cycle of 0.1% for devices exceeding 2 mW peak power in the 869.2 to 869.25 MHz band (consistent with the duty cycle for such devices previously specified in the Radiocommunications Regulations (SRD General User Radio Licence) Notice 2007);
2. amends the unwanted emission limit for devices operating up to 4 W peak power in the 921.5 to 928 MHz band from –36 dBm (as previously specified) to –46 dBm at the upper band edge, aligning it with Australian and US specifications;
3. specifies an unwanted emission limit at 915 MHz for devices operating up to 4 W peak power in the 921.5 to 928 MHz band. This will allow for the intended expansion of the band 921.5 to 928 MHz down to 920 MHz at the end of 2015, and ensure a consistent unwanted emission limit at 915 MHz.
