When you need to increase the cellular signal for multiple devices wirelessly,
mobile and building repeater systems are an excellent solution.
Our favorite is the 801241 - Wilson Cellular SignalBoost Mobile Professional Dual Band 800/1900MHz Cellular/PCS Wireless Amplifier Kit. Its perfect for the road warrior who wants to travel light. This kit contains the base cell phone signal booster as well as a 12" antenna, USB power cord to charge from your laptop, DC head for charging in your car, and AC head for charging in a motel room. It also includes a suction cup mount for the antenna so that you can mount the antenna to your motel room window. Finally, it includes a canvas case for all components.
While a direct connect cell phone signal booster does offer better single phone performance the
SignalBoost Mobile Professional Signal Booster is competitively priced and very portable easily fitting into a laptop case.
