The FiRa Consortium (its name means "fine line") includes companies such as Samsung, Bosch, Sony and LitePoint, and all are engaged in growing the UWB ecosystem. Building on the existing IEEE 802.15.4 / 4z standard, which defines the features of low-speed wireless data connectivity, FiRa uses it to set a new standard for technology that it believes could completely revolutionize everyday life.
UWB works by sending billions of pulses over a very wide frequency spectrum, with a bandwidth of several GHz. The corresponding receiver then translates the pulses into data by listening to a familiar pulse sequence sent by the transmitter. Since the modern UWB is limited to a very low power, there is very little interference with other wireless spectra. It is also secure and extremely accurate in terms of location detection.

In the 2000s, these advantages made UWB well suited for military and medical applications. Now, thanks to the IoT, which is booming, its uses are wider. According to FiRa, UWB could be used to identify a person's approach to or from a secure entry and to check security information without having their phone out of their pocket. It may be easier to navigate large places such as airports and shopping malls, or find a car in a multi-storey parking garage. It could even help you find a friend in a crowd.
Technology is still out of the way of consumer use, but it is already being exploited by businesses, particularly the automotive sector. Yongbum Park, vice president of the Telecommunications Technology Association, said: "Fine technology ranging from one device to the other without additional equipment is very useful for domestic or industrial applications. FiRa technology will change our lives. "
