What causes bad cell reception?
Cell signals are radio waves within the -50 to -120 dB frequency range, with -50 being full bars and -120 being no bars. You can view the exact signal strength being received by your Android phone in Settings -- About Phone -- Network. There are two major problems that will typically cause bad reception. First, there’s your geographic distance from a cell tower. If you’re too far away from a cell tower, your cell phone’s antenna won’t be able to receive a signal.Let’s take a look at each major wireless carrier’s cell coverage.

This app has WiFi and cell tower maps so you can find the coverage situation based on your GPS location.If you’re in a good coverage area and are still not getting a signal, something between you and the cell tower is interfering. Buildings, mountains, and other obstructions can cause a bad connection. So can network congestion. It’s also possible that the way you decorated your house can block reception. Even the weather can have a negative impact on a cell signal. Let’s explore ways to boost cell signals in common situations you come across daily.How to boost your signal at home or work
While indoors, your cell signal is most likely being blocked by two things. Both your (and your neighbor’s) WiFi network and the building materials of your home or office create cell signal interference.1. The easiest way to boost reception is to connect your phone to the WiFi network. It’s as easy as going to Settings -- Wireless and Networks and turning on WiFi. Select your WiFi network, enter the password when prompted, and you’ll connect.2. If you don’t have WiFi or can’t connect, the next option is to purchase and install a signal repeater like WeBoost Connect from Wilson Electronics. A repeater has a large external antenna that’s placed outside your home. Place it on the roof (or high on the wall facing the nearest cell tower) and connect it to an internal antenna to greatly increase coverage.Here’s an illustration to see what I mean.How to boost your signal while wondering town
Your cell reception can intermittently go out while wandering around town. Cell carriers (especially Verizon and AT&T) combat this by building WiFi networks in major retail chains, hotels, and public places.Connecting to these free WiFi networks will boost your phone reception. You benefit from the external rooftop antennas and hard-wired connections paid for by these businesses.
