2ApplicationCommunication applicationsUWB Communications applications using mitigation techniques as LDC (Low Duty Cycle) or DAA (Detect And Avoid) combined with TPC (Transmit power Control).
LDC UWB: used indoor or installed in automotive or railway vehicles in the band 3100 - 4800 MHz.
DAA UWB: used indoor in the bands 3100 - 4800, 6000 - 8500 and 8500 - 9000 MHz.
DAA UWB with TPC: installed in automotive or railway vehicles in the bands 3100 - 4800, 6000 - 8500 and 8500 - 9000 MHz.
Not applicable to devices and infrastructure installed at a fixed outdoor location or devices connected to a fixed outdoor antenna and devices installed in flying models, aircraft and other airborne environment.
