Electronic Communications Act, 2005 (Act No. 36 of 2005)RegulationsRadio Frequency Spectrum Amendment Regulations, 2021Part IX - AnnexuresAnnexure BReasons Document for the Annexure B of the Radio Frequency Spectrum Regulations 2015 - December 20216. Application-Specific Submissions6.5. Wireless Microphone Applications |
a. | In the Draft Annexure B, the Authority proposed the following frequency bands for Wireless Microphone Applications: |
36.65-36.75 MHz, 40.65-40.70 MHz, 53-54 MHz, 173.7–175.1 MHz, 402-406 MHz, and 863-865 MHz with their respective maximum power limits.
b. | Submissions received |
APWPT and SACIA proposed adding bands 470-694 MHz, 823-832 MHz, 1350-1400 MHz, 1518-1525 MHz, and 1785-1804.8 MHz on the list of apparatus exempt from radio frequency spectrum licenses for Wireless Microphones and In-Ear-Monitors as per ITU Regulations and the CEPT developments with a Maximum Power of 50 mW e.r.p. for all the proposed bands. They further proposed the addition of the reference material CEPT REC 25-10 and CEPT REC 70-03.
Audiomart, Audiosure, Kleens Music, Musiek Wêreld, Sight & Sound and Wild & Marr motivates for a license free spectrum be granted for any or all the band 470-790 MHz for wireless microphones
Gearhouse submits that they are currently services radio microphones and wireless in-ear monitoring equipment in the band 638-820 MHz and believes that the proposed allocation of band 863-865M Hz is not sufficient or viable to service their clients.
Multi-Media Event Trading submits that they supply microphones operating from brand 606 MHz to 822 MHz and believe if these bands are no longer allowed to be used, it will render their business useless and would not only lead to a loss of income but also the inability to serve their customers’ specific needs.
RF Junky submits that they have been operating at a range of 638-698MHz at 50mW, and 750-850MHz at 100mW for their wireless audio equipment’s, and they say the Authority taking away the entire use of the 470-850MHz would be a huge knock to the entertainment industry.
Sound Stylists proposes the frequency bands 470-636 MHz, 606-670 MHz, 638-698 MHz, and 750-822 MHz be added as new bands for wireless microphones.
SACIA proposes increasing power limitation from 50 mW ERP to 100 mW ERP throughout all bands for wireless microphones.
Get Connected, MGG Productions, Shockwave Music, XAV proposed allocation of band 863-865MHz is not sufficient or viable to service their clients.
Telkom requests the Authority to stipulate why the power of the wireless microphone in the band 53-54 MHz was changed from the value contained in the current regulations and recommends that this issue be confirmed and corrected as required.
c. | The Authority’s Response |
The Authority accepted the addition of the bands 470-694 MHz, 823-832 MHz, 1350-1400 MHz, 1518-1525 MHz and 1785-1804.8 MHz for wireless microphones, however the Authority adopted the Maximum Power limits for each band as supported by reference material CEPT/ERC/REC 70-03 and prescribed performance standard.
The Authority notes the recommendation to add CEPT REC 25-10 in the references, however the Authority maintains that CEPT REC 25-10 includes applications that are still under research and not yet supported by prescribed standards, and the Authority only adopts developed applications.
The Authority notes the recommendation to add the band 470-790 MHz, 638-820 MHz and band 606-822 MHz for wireless microphones, however the Authority added the band 470-789 MHz as supported by reference material CEPT/ERC/REC 70-03 and prescribed performance standard.
The Authority notes the recommendation to add the band 638-698 MHz at 50mW and 750-850MHz at 100mW maximum power for wireless microphones, however the Authority added the bands 470-789 MHz and 823-832 MHz, and their respective Maximum Power limit as supported by reference material CEPT/ERC/REC 70-03 and prescribed performance standard.
The Authority notes the recommendation to add the band 470-636 MHz, 606-670 MHz, 638-698 MHz, and 750-822 MHz for wireless microphones, however the Authority added the band 470-789 MHz as supported by reference material CEPT/ERC/REC 70-03 and prescribed performance standard.
The Authority notes the recommendations to increase the power limits for all bands of wireless microphones from 50 mW ERP to 100 mW ERP, however the Authority maintains that the power limits are in accordance with the performance standard SANS 300 422.
The Authority notes the submission about insufficient bands for Wireless Microphones, and the Authority resolved to open the bands 174-216 MHz, 470-789 MHz, 823-832 MHz, 1350-1400 MHz, 1518-1525 MHz, 1785-1804.8 MHz to address the concerns raised.
The Authority notes the submission regarding the change in power for wireless microphones in the band 53-54 MHz, however the Authority maintains that the power limit is as per the prescribed performance standard SANS 300 422.
