The Cel-Fi GO-M Smart Signal Booster for Verizon or AT&T by Nextivity is part of the next generation of intelligent signal boosters. Tough NEMA 4-rated design allows for outdoor installation and is weather-resistant against water, dust, and dirt. Unlike multi-carrier signal boosters with a limit of +50 dB, Cel-FiÕs single-carrier solution can boost signal up to +70 dB. ThatÕs a difference of +20 dB or up to 100x more power compared to multi-carrier boosters.
