Apple's first use of UWB is to provide positioning data. Location Supports Many applications in the fields of reality (AR), virtual reality (VR), games, equipment recovery, file sharing, and advertising beacons.
Development of UWB technology
With the growth of wireless communication demand in 1990, the advantages of ultra-wideband (UWB) become more obvious.
In 2002, Wi-Fi is still a relatively new technology. The 802.11b router was launched in 1999, the theoretical maximum speed of the 2.4 GHz band is 11 Mbit / s.
802.11A standard is also defined in 1999 and promised that the theoretical speed in the 5 GHz band is 54 Mbit / s, but due to its higher chip group cost, there is no attention in the consumer.
The 7.5 GHz bandwidth allocated between 3.1 GHz and 10.6 GHz is extremely valuable for wireless communication engineers.
