Numerous field trials have validated the feasibility of using these technologies to deliver broadband access. Our Researchįor over a decade, Microsoft Research has been inventing new technologies to perfect these techniques. Underpinned by a regulatory framework that maximizes spectral efficiency and minimizes barriers to market entry, application of these new technologies will help networks and markets scale to inexpensively deliver the services demanded by consumers.

These excellent range and obstacle penetration characteristics explain why people increasingly refer to TV white spaces as “Super Wi-Fi.”Īlthough the first globally-harmonized opportunity to showcase DSA is occurring through license-exempt (unlicensed) access to the TV band white spaces, DSA technologies will be used in a variety of spectrum bands. The first globally-harmonized opportunity to use DSA technologies will be in the TV band white spaces – unused VHF and UHF TV channels that can be used to deliver broadband access over wider areas than possible using today’s Wi-Fi spectrum. These technologies ensure that consumers and their devices have wireless bandwidth when and where they need it. One example is Dynamic Spectrum Access (DSA), a term used to describe a set of technologies enabling radio communications devices to opportunistically transmit on available radio spectrum. Wireless technologies and management techniques exist today that can replace artificial spectrum scarcity with naturally occurring spectrum abundance. Availability and affordability gaps are disproportionately impacting people in Africa, Asia, and Latin America. Mobile broadband is unaffordable for over 2.6 billion people. Fixed broadband access is unaffordable for 3.9 billion people spread across every country in the world. In addition, hundreds of millions of wirelessly-connected devices are coming online, all requiring wireless connectivity and bandwidth, further increasing demand for spectrum resources.Īt the same time that available spectrum resources are being constrained in many markets, broadband access remains unavailable and/or unaffordable for several billion people around the world. Unfortunately, even in the most developed economies there are gaps in wireless coverage, access points and base stations become overloaded in busy areas, and pricing presents an affordability barrier for many.

Whether it’s a simple ping from a rubbish can to the nearest rubbish truck, a school in a remote village connecting to teachers in the capital, or a group of friends watching the latest hi-def movie on a phone, broadband-quality wireless connectivity is essential.
Consumers expect instant access to their favorite services regardless of which device they happen to be using, where they happen to be, and what time it is.
Maina’s firstConsumers have access to an increasing range of connected devices, for use in and out of the home – the vast majority relying on wireless technologies.
