Wilson Electronics has released the SignalBoost, a dual-band amplifier that should work with any cellphone or PCS carrier. The device uses 3W of power to increase mobile output signal, strengthening it by as much as 10 to 15 times over its normal levels. To further improve performance, users can also use various antennas, or the bundled DC power connector for car cigarette lighters. The SignalBoost should function with cellular-based laptop modems as well. Sites such as AlternativeWireless are selling the device for $220.
