Within the square, several large lighting towers were rigged with more than 300 computer lighting fixtures plus several powerful searchlights, totalling more than 500 lighting fixtures in all. All of these lighting fixtures were controlled with only four lighting consoles.
To achieve the multitude of lighting changes while overcoming the difficulty of the long transmission distance without any cables, Leifull Light and Sound of Guangzhou proposed an effective solution. They supplied four W-DMX systems from Wireless Solution Sweden to control the searchlights and the area light of the Tiananmen Tower, and used a 6dB high-power antenna to guarantee the signal's stability.
The entire W-DMX system performed flawlessly from the time lighting programming commenced on 5 August to the end of the ceremony on 8 August.
