Better Cell Signal for Large Homes Is Available!

Solving cellular reception problems in a large, luxury home requires more than just an off-the-shelf cell signal booster. Luxury homes are often constructed like commercial buildings, with decorative concrete, steel, stone, low-e glass, and hard woods. These kinds of building materials can interfere with cellular reception inside the home.

Powerful Signal specializes in bringing strong cellular voice and data into large, luxury homes. Our cellular boosters for large homes can fix specific problem areas or provide whole-house coverage.
