UWB technology is not planning to be used for connectivity but instead for location based services since it offers fine ranging which would allow to deliver a high level of accuracy of the position of the device and also the distance. It can be used for all non-GPS i.e. indoor or similar use cases where the exact location is important.
The FiRa consortium is backed with some well-known industry names: ASSA ABLOY Group, NXP Semiconductors, Samsung Electronics, Bosch, Sony Imaging, LitePoint and the Telecommunications Technology Association (TTA) so the technology probably has potential.
