So, using wireless equipment not approved for legal use is rendered illegal. Now, the 703-Mhz - 803 Mhz range has been allocated to various telco operators to provide 5G mobile services hence this range is unavailable to wireless microphone operation. At the time this article is published, the allocated frequency range allowed for licensed wireless microphone systems is 470.00 – 806.00 MHz and limited to ≤ 10 mW ERP of power Wireless Microphone systems are classified under IMDA TS SRD. Since many have asked, IMDA's licensing guidelines stipulate that all wireless microphones conform to certain technical limitations to qualify for licensing and use in Singapore. 'IMDA has made available spectrum in the 700 MHz Frequency Division Duplex (FDD), 900 MHz (FDD), 1800 MHz (FDD), 2100 MHz (FDD), 2.3 GHz Time Division Duplex (TDD), 2.5 GHz (FDD) and 2.5 GHz (TDD) frequency bands for the provision of public mobile services - Jul 9, 2017'
This affects most of the older models of wireless microphones sold before 2018. Did you know? Wireless microphone systems in the range of 703-748 MHz/758-803 MHz is now unusable in Singapore due to frequency allocation for 5G mobile services.
