Transforming Indian Offline Retail and Customer Engagement Using AI
The technology industry has called on the Department of Telecommunications (DoT) to revise proposed power levels for wireless devices operating in the delicensed 6 GHz spectrum band, warning that current limits may hinder the performance of next-generation applications and restrict consumer access to affordable, high-speed Wi-Fi.

DoT’s Draft Rules for 6 GHz Band
The DoT has released draft rules for the use of low-power and very-low-power wireless systems in the lower 6 GHz band (5925–6425 MHz), which has been delicensed and allocated for unlicensed use without auction. Once finalized, the rules will enable the deployment of the latest Wi-Fi routers, gaming consoles, and immersive technologies in India.
However, according to an ETTelecom report, industry experts have raised concerns over the DoT’s proposed maximum power spectral density (PSD) of -5 dBm/MHz and a total transmit power limit of 14 dBm for very-low-power devices. They argue that these constraints could significantly reduce the range and throughput of such devices, impacting high-bandwidth applications including augmented reality (AR), virtual reality (VR), and mixed reality (MR), which require low latency and high throughput.
Industry Pushes for Higher PSD
The industry is urging the DoT to raise the PSD limit to 1 dBm/MHz for very low-power devices, both indoors and outdoors, to support these emerging applications. While this revision would not benefit wide bandwidth channels (80/160/320 MHz), it is expected to substantially improve performance for devices operating on 20 MHz and 40 MHz channels.
