Official response and comment from the Dynamic Spectrum Alliance
“The DSA is all about promoting and enabling spectrum sharing of all guises. This means we prefer balancing more shared spectrum utilisation over exclusive utilisation, balancing static allocation with more dynamic allocation, and balancing licensed regulations with more unlicensed regulations. So naturally, we support plans worldwide to open up more spectrum to unlicensed access from devices and unlicensed sharing,” said Professor H Nwana, Executive Director of the Dynamic Spectrum Alliance.
“Having an insufficient amount of spectrum available for license-exempt devices presents a real barrier to proliferating public Wi-Fi across India,” he added. “The DSA is fully supportive of TRAI’s effort to increase broadband coverage and capacity.”
The DSA believes that dynamic spectrum sharing would allow available spectrum to be used more efficiently than any existing static techniques. Introducing dynamic spectrum access would enable access to spectrum in a given band to be coordinated in real time (or near-real time), and the amount of spectrum adjusted depending on the service demand at any given moment, whilst taking into account geographic characteristics. Dynamic spectrum sharing can utilize a combination of technologies, including but not limited to geo-location databases, access control technologies, sensing, and data analytics to allocate the available spectrum in the most efficient manner. Such dynamic solutions would allow for innovative sharing with different services across the sub-bands, ushering in considerable innovation for public Wi-Fi operators.
“We strongly suggest TRAI increases the amount of license-exempt spectrum available through dynamic spectrum sharing in segments of the 5 GHz band, the TV White Space, high-band spectrum (71-76 GHz and 81-86 GHz), as well as assigning the lower part of 6 GHz and the entire 57-71 GHz range for license-exempt use. With these steps there will be enough spectrum to fully support TRAI’s objective of expanding broadband through the proliferation of public Wi-Fi in India,” concluded Nwana.
Earlier this year the Dynamic Spectrum Alliance welcomed the Indian Government’s move to issue eight new licenses in the 470-582 MHz band. The purpose of these is to carry out experiments at several locations using TV White Space-like-rules and regulations already adopted (or being adopted) in other countries such as Malawi, Ghana, Singapore, the Philippines, UK, USA and Canada. This decision opens up opportunities for the use of sub-1GHz spectrum in India for Wi-Fi too, in either an unlicensed or lightly licensed fashion, without the need for spectrum auctions.
