FiRa Consortium Publishes PHY Technical Requirements Specification

As a first step in ensuring an interoperable UWB ecosystem across chipsets, devices and services infrastructures, the FiRa™ Consortium has announced the availability of the FiRa Consortium PHY Technical Requirements Specification, Version 1.0 to prescribe hardware and RF communications, the company said.

The early availability of the PHY Technical Requirements Specification will help providers to execute quickly on the development of tools, chipsets, and other necessary components and services.

Additionally, the FiRa Consortium Technical Working Group has completed the MAC Technical Requirements Specification which is now in the review process. The Working Group is monitoring industry activity to ensure that the MAC specification is aligned with industry best practices and will support the vision of an open and interoperable ecosystem. This Working Group continues to develop security and performance parameters to promote a superior user experience for end-users of UWB-enabled products.

The basis for the new FiRa Consortium PHY Technical Requirements Specification is the High Rate Pulse (HRP) portion of the IEEE 802.15.4-2015™ technical specification and 802.15.4z™/D06 draft amendment for fine-ranging UWB technology. The work done by the IEEE 802.15.4z Enhanced Impulse Radio (EiR) Task Group included defining a series of PHY enhancements to improve the capabilities of UWB devices with corresponding MAC changes. These enhancements included improvements to existing modulations to increase the integrity and accuracy of ranging measurements and additional information element definitions to facilitate ranging information exchange.

The FiRa Consortium PHY Technical Requirements Specification will be used as the foundation for other specifications and certifications being driven by the FiRa Consortium. This Specification will provide FiRa Consortium members with an overview of the UWB ranging technology that has been developed and will provide guidance to developers who are actively working to develop new products based on UWB technology.

Headquartered in Beaverton, OR, the FiRa Consortium is a member-driven organization dedicated to the development and widespread adoption of seamless user experiences using the secured fine ranging and positioning capabilities of Ultra-Wideband (UWB) technologies.
