The appeal and freedom of cordless microphones, wireless speakers and other wireless systems is growing -- and so are the options! They range from small personal body-worn voice amplification systems to large venue sound systems and high-quality speakers providing full, clear sound. In general, the wireless options are portable or fixed.

Portable wireless -- the operation of autonomous, battery-powered wireless devices or systems you can take with you outside the office or home like portable PA systems, cordless microphones, headsets and speakers.

Fixed wireless -- the operation of wireless equipment or systems inside homes and offices like home-entertainment control units and robot control systems.
