What is Wireless HDMI and How Does it Work?
Wireless HDMI is a technology that allows for the transmission of audio and video signals from a source device to a display device without the use of cables. It uses radio frequency (RF) or infrared (IR) signals to transmit the signal wirelessly. This technology is often used in home theaters, presentations, and other applications where cables are not feasible or desired. Wireless HDMI systems typically consist of a transmitter connected to the source device and a receiver connected to the display device.
The transmitter converts the HDMI signal into a wireless signal, which is then transmitted to the receiver. The receiver converts the wireless signal back into an HDMI signal, which is then sent to the display device. Wireless HDMI systems operate on a specific frequency band and use encryption to ensure that the signal is secure and not interrupted by other devices. This allows for a wireless range of up to 100 feet or more, depending on the system and environment.
