For those uninformed, UWB is a wireless communication protocol that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. The technology is superior to both Bluetooth and Wi-Fi in terms of precision and security. According to
PCWorld, UWB is extremely low power, but the high bandwidth (500MHz) is ideal for relaying a lot of data from a host device to other devices up to about 30 feet away. Unlike Wi-Fi, however, it is not particularly good at transmitting through walls.
It’s not just Samsung and Apple that are working on this technology. Companies like Huawei, Xiaomi are also expected to introduce UWB in their future smartphones.
