More details from American DJ (www.americandj.com):
One WiFlex transmitter can send a constant/reliable signal to several WiFlex receivers. The WiFlex DMX system features a special frequency-hopping algorithm that promises to avoid “blackout” periods caused by interference from other W-LAN or any other wireless products using the 2.45 GHz band, only using channels that are not in use. WiFlex DMX is well-suited for DJs, nightclubs, bars and other events where cables would be unsightly or impractical.
