RFID offers only spot localization because of its limited range, ultra-wideband is ideal for area-wide localization. The indoor positioning sensor is capable of pinpointing the location of the asset close to a few centimeters. Ultra-wideband technology has become a familiar term ever since iPhones started to include UVW technology. As opposed to Bluetooth LE, UWB is complex to use. It is reliable even in hostile environments and is preferred for its low transmit power.
