Wilson Electronics announces an in-building wireless dual-band cellular amplifier with innovative Smart Technology. The small office/home office (SOHO) bi-directional amplifiers improve signal quality and strength for voice and data. The SOHO dual-band, Cellular / PCS amplifier improves the signal in the 800 and 1900 MHz bands by 50 decibels, for simultaneous amplification for multiple phones and carriers. Bi-directional amplifiers prevent oscillations and adjust power based on cell site requirements, preventing overload of the carrier's network or interference with other users on the system. The SOHO signal booster is wireless and requires no physical connection to a cell phone or cellular data card. It works on CDMA, TDMA, GSM and the latest high-speed data technologies.
