In November 2020, Android Open Source Project received first patches related to an upcoming UWB API feature-complete UWB support is expected in later versions of Android. Samsung, Xiaomi, Oppo are currently members of the FiRa Consortium. The FiRa Consortium was founded in August 2019 to develop interoperable UWB ecosystems including mobile phones. The Xiaomi MIX 4 released in August 2021 supports UWB, and capabilities of connecting to select AIoT devices. The Samsung Galaxy Note 20 Ultra and Galaxy S21 Ultra and S21+ also support UWB, along with the Samsung Galaxy SmartTag+.

Apple also launched Series 6 of Apple Watch in September 2020, which features UWB, and their AirTags featuring this technology was revealed at a press event on April 20, 2021.

The UWB part is based on the IEEE 802.15.4.z standard.Īpple launched the first three phones with ultra-wideband capabilities in September 2019, namely, the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. The omlox technology standard enables the provision of location data independent of technology and manufacturer. UWB is also useful for peer-to-peer fine ranging, which allows many applications based on relative distance between two entities. UWB is useful for real-time location systems, and its precision capabilities and low power make it well-suited for radio-frequency-sensitive environments, such as hospitals. With a cooperative symmetric two-way metering technique, distances can be measured to high resolution and accuracy. This helps overcome multipath propagation, since some of the frequencies have a line-of-sight trajectory, while other indirect paths have longer delays. Ī UWB radio system can be used to determine the "time of flight" of the transmission at various frequencies. Pulse-UWB systems have been demonstrated at channel pulse rates in excess of 1.3 billion pulses per second using a continuous stream of UWB pulses (Continuous Pulse UWB or C-UWB), while supporting forward error-correction encoded data rates in excess of 675 Mbit/s. UWB pulses can be sent sporadically at relatively low pulse rates to support time or position modulation, but can also be sent at rates up to the inverse of the UWB pulse bandwidth. The information can also be modulated on UWB signals (pulses) by encoding the polarity of the pulse, its amplitude and/or by using orthogonal pulses. UWB transmissions transmit information by generating radio energy at specific time intervals and occupying a large bandwidth, thus enabling pulse-position or time modulation.
Thus, pulse-based systems-where each transmitted pulse occupies the UWB bandwidth (or an aggregate of at least 500 MHz of narrow-band carrier for example, orthogonal frequency-division multiplexing (OFDM))-can access the UWB spectrum under the rules.Ī significant difference between conventional radio transmissions and UWB is that conventional systems transmit information by varying the power level, frequency, and/or phase of a sinusoidal wave. Ultra-wideband was formerly known as pulse radio, but the FCC and the International Telecommunication Union Radiocommunication Sector ( ITU-R) currently define UWB as an antenna transmission for which emitted signal bandwidth exceeds the lesser of 500 MHz or 20% of the arithmetic center frequency. Regulatory limits in many countries allow for this efficient use of radio bandwidth, and enable high-data-rate personal area network (PAN) wireless connectivity, longer-range low-data-rate applications, and radar and imaging systems, coexisting transparently with existing communications systems. This allows for the transmission of a large amount of signal energy without interfering with conventional narrowband and carrier wave transmission in the same frequency band. Ultra-wideband is a technology for transmitting information across a wide bandwidth (>500 MHz).
