One of the most impressive parts of using ultra wideband is the fact that it can function appropriately even in the presence of environmental obstacles. That said, one of the external conditions that UWB struggles with is smoke. Smoke can alter the performance of the technology because fundamentally it still makes use of the radio spectrum and radio waves which can be absorbed, reflected or scattered by smoke. In some cases, UWB accuracy may still be high even in the presence of smoke. Some of the factors that can impact just how effectively the technology performa under this condition include the density of the smoke, the power of the UWB transmitter, and the frequency of the UWB system.
