Cellular and first-responder coverage that reaches inside the building

Nextivity brings the outside cellular network inside, filling the dead zones in buildings where phones lose signal and first-responder radios go quiet. Its CEL-FI systems cover commercial cellular for people and devices, and its SHIELD systems deliver the public-safety radio coverage that fire and building codes increasingly require.

Why Sector Carries Nextivity

Bring the network inside the walls

Modern buildings, with their concrete, metal, and energy-efficient glass, block the cellular signal people and devices depend on. Nextivity systems pull the outside network in and rebroadcast it cleanly, so coverage reaches the basements, stairwells, and back corners where phones normally go dark.

The coverage that passes inspection

A growing number of jurisdictions require in-building radio coverage for first responders before a building can get its certificate of occupancy. Nextivity's SHIELD systems are built for exactly that, boosting public-safety radio and FirstNet so a building can pass its inspection and keep responders connected inside.

Smart signal, not a dumb repeater

Nextivity's IntelliBoost technology cleans and channelizes the signal instead of blindly amplifying it, which keeps the system from creating noise on the carrier's network. The systems are carrier-approved, run over standard network cabling, and install faster than the legacy DAS they replace.

About Nextivity

Nextivity has spent nearly two decades on a single problem: cellular signal that cannot get inside a building. Founded in San Diego in 2006, it designs its own silicon and signal-processing technology, called IntelliBoost, and holds patents across the hardware, software, and antennas that make its systems work.

The company's coverage comes in two lines. CEL-FI handles commercial cellular, bringing carrier signal into offices, warehouses, hospitals, schools, and other buildings where dead zones cost time and safety. SHIELD handles public safety, delivering the in-building radio and FirstNet coverage that fire and building codes increasingly require for a certificate of occupancy. Both are carrier and FCC approved and built to install without heavy RF engineering.

Sector carries Nextivity because in-building coverage is a real and growing need, driven both by frustration with dead zones and by public-safety codes that now mandate it. Whether the goal is keeping a warehouse connected or getting a new building through its occupancy inspection, Nextivity is the line we deploy to fix coverage from the inside.

Losing cellular or radio signal inside a building?

Our team knows the Nextivity CEL-FI and SHIELD lines and can spec in-building coverage for cellular, first-responder radio, or both, whether it is a school, a warehouse, or a facility that needs to pass its occupancy inspection. Tell us the building and the problem and we will scope the system.
