CHELMSFORD, MASS.—As broadcasters find themselves one month into Phase 2 of the FCC spectrum repack, the effort to develop technologies to enable use of remaining vacant TV channels for other purposes picked up momentum with advances in the specification for Wi-FAR networks.
The WhiteSpace Alliance (WSA) this week announced publication of an expansion of its test vector format specification for Wi-FAR networks. The spec defines a standard, implementation-independent language for test vectors to evaluate and certify interoperability of TV white space Wi-FAR implementations, a WSA press release said. AmeriSys Inc. in Canada proposed the enhancements, which WSA approved.
The alliance developed Wi-FAR as a derivative of the IEEE 802.22 wireless regional area network standard. It supports line-of-sight and non-line-of-sight broadband services at distance up to 18 miles. Uses of the technology include middle- and last-mile internet services for rural and remote areas as well as Internet of Things (IoT) applications.
The update adds new functions to the original specification, the alliance said. It includes new MAC (Media Access Control) layer commands and header parameters. It also provides a base station reference model, WSA said.
According to WSA, the update includes detection and reporting of incumbent services providers, which it says will support coexistence with TV broadcasters.
More information is available on the WSA website.
