What Are White Space Devices (WSD)?
White Space Devices (WSD) are a category of wireless communication devices that use unused or underutilized frequencies in the radio spectrum, often referred to as “white spaces.” These frequencies are typically found between licensed television broadcast channels, but they can also include unused portions of other bands of the spectrum. By tapping into these frequencies, WSDs are able to provide wireless broadband services, with significant advantages in terms of coverage area, signal penetration, and cost-effectiveness.
The idea behind WSDs stems from the fact that many television broadcast channels do not utilize all of the frequencies within their allocated spectrum. In urban areas, the demand for these frequencies is often high, but in rural or sparsely populated regions, many of these channels remain unused. WSDs can take advantage of this unused spectrum to deliver high-speed internet and communication services without interfering with existing licensed services.
