| TVWS - Turning Spectrum Scarcity into Spectrum Opportunity |
| Television white spaces (TVWS) refers to frequencies in the very high frequency (VHF) and ultra-high frequency (UHF) television bands not assigned or otherwise used by broadcasters or by any other licensed services. With the assignment of channels to broadcasters varying by location, not all the allocated channels are assigned to broadcasters in any given market, giving rise to “white spaces” in which a channel that is not assigned for broadcast may be available for other purposes. TVWSs are a great example of spectrum sharing; regulators allow TVWS devices to transmit on these unassigned channels without the need of a license (unlicensed spectrum). TVWS can be used to provide broadband connectivity and telemetry for Internet of things (IoT) solutions. TVWS can be deployed in conjunction with 5GHz and other mid-band links to increase the coverage area and to cover the missing spots that cannot be addressed by 5GHz and other mid-band links due to non-line of sight (NLOS) and distance limitations. |
