UWB (Ultra-Wideband) is a protocol designed for high-speed data transfer over short distances. It has a very low power consumption and can penetrate through walls and other obstacles, making it a good choice for transmitting signals through doors. Wi-Fi and Bluetooth can also achieve high transfer rates, but they may suffer from interference or loss of signal when passing through walls, which could result in a slower transfer rate. IrDA is not a suitable option for transferring video because its transfer rate is much slower than UWB, Wi-Fi, and Bluetooth.
