Allocation of 6 GHz band in Singapore

This allocation will ensure a seamless experience for end-users

The Infocomm Media Development Authority (IMDA) of Singapore has announced plans to allocate more radio frequency spectrum to enhance Wi-Fi connectivity in the country. This will involve allocating 500 MHz of spectrum in the 6 GHz band specifically for Wi-Fi use.

The lower segment of the 6 GHz band, ranging from 5,925 MHz to 6,425 MHz, has been identified globally as suitable for Wi-Fi use. This additional spectrum will enable the deployment of the latest Wi-Fi 6E technology, which supports wider Wi-Fi channels, including 160-MHz channels. These channels are 2 to 8 times wider than the current 20-MHz to 80-MHz channels in the 2.4 GHz and 5 GHz bands.

The availability of wider 160-MHz channels will offer faster theoretical maximum speeds of up to 9.6 Gbps, doubling the current maximum speeds of up to 4.8 Gbps. Additionally, it will support lower latency use cases, providing an improved experience for bandwidth-intensive and low latency applications.

The allocation of more spectrum in the 6 GHz band is essential to meet the growing demand for data-intensive and low latency use cases, such as interconnected devices, robots with autonomous mobility, generative AI, and augmented or virtual reality experiences. It will reduce contention over Wi-Fi and maintain a good user experience as these applications become more prevalent.

Furthermore, this allocation will ensure a seamless experience for end-users as they transition between different connectivity options in Singapore. While the Nationwide Broadband Network (NBN) provides high-speed fibre broadband connectivity, Wi-Fi serves as the primary connectivity medium for in-unit or in-building wireless connectivity. Wi-Fi technology needs to keep pace with NBN developments to deliver the full potential of the next-generation technology upgrade.

For enterprises, the enhanced Wi-Fi connectivity will enable greater digital innovation, improving efficiency and productivity. It will support augmented and virtual reality experiences at scale, workplace training, and Industry 4.0 innovations like robotics and high-definition video monitoring.

For consumers, the improved Wi-Fi connectivity will enhance home connectivity for bandwidth-intensive activities like remote working, home-based learning, and entertainment. It will also ensure a seamless experience as devices transition between Wi-Fi and 5G connectivity.

IMDA plans to amend its regulations to allocate the 5,925 MHz to 6,425 MHz spectrum for Wi-Fi use. Commercial availability of Wi-Fi 6E-enabled equipment and devices in Singapore is expected by the third quarter of 2023.
