It operates over a lower frequency as compared to other services which allow it to propagate over long distances with minimal interference. There are multiple reasons why TVWS stands out. How is TVWS (TV White Space) better than traditional technologies?
One of the biggest problems in rural areas is that houses are separated by long distances and it's very difficult to connect them using cable and fiber otpic lines. In rural areas, providing a wired broadband connection can be costly and inefficient. TVWS is a solution to provide more people with internet access where traditional methods fail to be efficient. Both developed and developing countries contribute to this number. Wireless communication and TV broadcasting have come a long way now and research has proven that these gaps can be used to provide broadband internet access while operating hand-in-hand with TV channels operating in surrounding bands.Īlthough internet access has expanded exponentially over the last years, approximately 3.9 billion people still don’t have a fixed broadband connection. Back then spectrum was not such a precious commodity. These gaps or white spaces are present because in the past, active TV channels placed buffers in between them to prevent interference. This unused frequency can be used to provide wireless internet services. TV White Space or TVWS refers to the unused frequencies or gaps in the VHF and UHF spectrum, between 470 and 790 MHz to be precise (This pertains to the United States). Large amounts of lower band spectrum which was originally blocked for TV broadcasting is unused. However, there this is not the case for the sub-800 MHz spectrum.
With the introduction of 4G, 5G, IoT and a whole plethora of devices and services, the frequency spectrum above 800 MHz has been becoming more and more crowded. It is no secret that wireless communication has been growing rapidly over the years.
