WLAN for hotels, event locations, or schools. With the Speaka Professional HDMI wireless transmission set, consisting of a transmitter and receiver module, WLAN is distributed up to 100 meters with a direct line of sight. The latest wireless video transmission technology in UltraHD has been integrated into the devices, allowing for seamless transmission of a 4K signal—whether in the hotel lobby, a large hall, or training rooms. Two telescopic antennas ensure smooth reception, while both the receiver and transmitter can be powered via micro-USB cables. Additionally, the IR extender function allows for the use of a playback device's remote control through the receiver.
