What are TV White Spaces?

TV White Spaces (TVWS) refer to the unused TV channels between the active ones in the VHF and UHF spectrum.

In the TV band, white spaces exist because television stations on the same channel operate in geographically separate areas and because, in areas with low population density, not all television channels are used.

Harnessing the White Spaces

TV White Space technology harnesses unused TV band spectrum to deliver wireless internet services while operating harmoniously with surrounding TV channels. TV White Space equipment like the Adaptrum ACRS2 radios access unused channels by interacting with a spectrum database to determine channel availability at specific locations.

Adaptrum was an early pioneer in the theory and implementation of radio technologies that make emerging dynamic spectrum access policies possible. Adaptrum dynamic spectrum access solutions help unlock licensed bands without interference, allowing for sharing available spectrum in a more coordinated way.

The Benefits of TVWS

The combination of low frequency spectrum and dynamic access rules for TVWS make it uniquely suited for affordably delivering broadband connectivity.

Long-Range

The low sub-GHz frequencies used by TVWS allow it to propagate farther than higher frequency systems, including those at 2.4GHz & 5.8GHz, used to deliver wireless broadband today. Long range coverage translates to covering more customers with existing infrastructure, and requiring less investment to expand service footprints.

Non-Line-of-Sight (NLOS)

Beyond long-range propagation, the low sub-GHz frequency allow links to penetrate trees, buildings, and other obstructions – providing true non-line-of-sight (NLOS) connectivity. This makes TVWS ideal for deployments in rural forested areas.

High Channel Availability

In many parts of the world, TV broadcast spectrum is severely underutilized. This presents a massive opportunity for operators who want to deploy TV White Space equipment to provide broadband connectivity.

Dynamic Spectrum Access

The cognitive radio system that enables dynamic access to the TV White Space spectrum is comprised of two primary components: wideband frequency agile radios such as the Adaptrum ACRS2 and spectrum access databases.

White space radios are designed to operate across the full UHF band supporting country specific channel bandwidths (6/7/8 MHz) enabling use of any available TV White Space channels. To ensure interference-free operation, Adaptrum radios have been certified to meet, and in many cases, exceed strict radio performance specifications.

Adaptrum has partnered with a number of leading database providers, which provide an authorized list of available TV White Space channels based on individual radios locations.
