thumb_Cordless ESI Cordless Handset uses proven, reliable 900 MHz technology to provide mobility to the user who’s constantly on the move in the office. (Why 900 MHz? Because it passes through walls far more effectively than cordless telephony using the 2.4 GHz and 5.8 GHz bands, which are intended more for residential than workplace use.)
