Ultra-wideband (UWB) is a short-range, wireless communication protocol that operates through radio waves, enables secure reliable ranging and precision sensing, creating a new dimension of spatial context for wireless devices.
Makerfabs ESP32 UWB module is based on DW1000, it acts like a continuously scanning radar, that precisely locks onto another device (called Anchor) and communicates with it, thus calculating its own location. Once the device is near another UWB device, the devices start “ranging.” Ranging refers to calculating the time of flight (ToF) between devices: the roundtrip time of challenge/response packets.
The new version ESP32 UWB DW3000 is interoperable with Apple U1 chip, which makes it possible to work with the Apple system.
Besides, with ESP32 WiFi connection, it can easily report its location to the remote receiver, so the receiver can monitor its latest location.
