USB Cell Phone Booster
Cell Ranger is a USB powered device that will give 2-3 bars extra signal for any cell phone or 3G data card. Simply plug the signal booster into your computer’s USB port, place the antenna near a window, and start enjoying your new and improved reception.
Cell Ranger products contain a microprocessor that actively analyzes the signals that your cell phone is receiving. By comparing the signal strengths of different towers, the microprocessor self-tunes to the correct channels. This innovative technology means that Cell Ranger products are carrier friendly – they only amplifies the signals that your cell phone needs.
