How can I get better cell signal in a metal building?
Cellular devices operate in the UHF band
of the radio spectrum, which is reflected by metal roofs and walls. (Click to enlarge.)
Most metals reflect radio signals, including frequencies used by cellular phones. Buildings made with metal roofs and walls often have little to no cell signal inside, cutting off access to phone calls, email, and SMS text messages.
A cell phone signal booster is an excellent option to solve poor cell signal in metal buildings. The size of your building will determine the booster system you need to solve the problem. Most individuals and businesses can install a small, one-booster system themselves; larger, multi-booster solutions are most effective when designed by a professional, experienced design engineer.
How does a cellular booster improve signal in a metal building?
Cell signal booster systems use a roof-mounted antenna to collect available signal outside, then send that to an amplifier unit that increases the signal gain. The amplifier then feeds the improved signal to one or more inside antennas that broadcast to phones and other cellular devices. (For more about this, see our Guide to Home Cell Signal Boosters.)
