Wireless Microphone bandwidth shrinking in Singapore

Wireless Microphone bandwidth shrinking in Singapore *Updated*

Did you know? Wireless microphone systems in the range of 703-748 MHz/758-803 MHz will be unusable in Singapore in the near future. This will affect the very popular Shure SLX P4 band.

"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"

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. Wireless Microphone systems are classified under IMDA TS SRD. 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

Once the 703-Mhz - 803 Mhz range is allocated to Singapore's 4th telco operator, this range becomes unusable. So while it is still currently legal, it wont be for much longer so buy wisely and avoid buying systems in the affected range.

To help with choosing wireless systems, we have compiled the useable frequency bands of Shure and Sennheiser for your convenience
