Why modern buildings lose signal

Low-emissivity glass, steel framing, concrete decks, and underground parking are excellent at keeping weather out and equally good at keeping cellular signals out. The result is a building that looks new and feels disconnected the moment a resident steps off the sidewalk.

Distributed antenna systems

A DAS captures carrier signals from a rooftop antenna or a direct carrier feed and distributes them through the building over fiber and coaxial cable to small antennas on each floor. Residents on every major carrier get a strong, consistent signal in their units, the elevators, and the garage.

Boosters for smaller buildings

Garden-style and mid-rise communities often need only carrier-approved signal boosters in the problem areas. We measure the signal, identify the dead zones, and specify the smallest system that solves the problem.

Public-safety coverage

Many jurisdictions now require in-building coverage for first-responder radios before a certificate of occupancy is issued. ResidentFi designs and installs emergency responder communication systems and coordinates the testing with the authority having jurisdiction.
