MOBGILE PHONE SIGNAL BOOSTERS IN KOLKATA

Description Now that many of us are working from home, cellular dead zones aren't just annoying, they're mission-critical. If you have weak or no cellular signal in your home, a cellular signal booster can really help. The basic principle behind signal boosters is simple: A big antenna is better than a small one. Instead of relying on the tiny antenna in your phone, they capture cellular signal using a large antenna in your window or outside your house (or car), then pass that signal through a device that cleans and amplifies it, and out through a rebroadcaster inside your home. That's the basic plan, at least. Booster makers have to use various tricks to detect the best signal from surrounding towers and then amplify the signal without messing up the carriers' systems. That's why you need to stick with boosters from the big four companies: Cel-Fi, HiBoost, SureCall, and weBoost. Cheaper boosters sold on Amazon often aren't FCC-certified, which means they can cause trouble with surrounding cell sites and networks.
