No dead zones on the floor
Warehouses, plants, and offices the size of a city block lose signal the moment the walls go up. Sector designs in-building cellular and public-safety coverage that holds across the whole facility, and gets new construction past the fire marshal.
A steel building is a signal trap
Manufacturing plants, warehouses, and large offices are built from the exact materials that block cellular signal: steel, concrete, and coated glass. The bigger the footprint, the more of it sits far from any window or tower. Staff lose calls, scanners and monitored systems drop off, and a 911 call from the back of the building may not connect at all.
New construction adds a second problem. Once a building passes a certain size, fire and building codes require a public-safety radio system so first responders stay on their radios inside. The fire marshal checks for it, and without it there is no Certificate of Occupancy.
Sector handles both, and sizes the system to footprints that can run past a million square feet.
WHY SECTOR FOR THIS SOLUTION
Built for big footprints
A single system covers very large buildings, and units combine for facilities over a million square feet. We size it from a real signal survey of your building, not a guess.
Certificate of Occupancy on the first try
For new construction, we design the public-safety system to code, submit to the Authority Having Jurisdiction, and run the grid testing the inspection requires, so the build isn't held up at the finish line.
We stay after the install
Quarterly preventive maintenance, 24/7 remote support, and warranty handling under one maintenance agreement keep the facility covered and in compliance.
TWO KINDS OF COVERAGE, ONE BUILDING
Everyday cellular that doesn't drop
A distributed antenna system pulls the outside signal in and redistributes it through the building over standard Ethernet cabling, boosting all major carriers at once. It runs fully digital, installs without tearing the place apart, and is network-safe, so it won't interfere with the carrier networks. Coverage holds on the floor, in the back office, and in the spots that never had a bar before.
The system the fire marshal is looking for
Large buildings need an Emergency Responder Radio Coverage System so police, fire, and EMS keep radio and FirstNet contact inside. Sector designs these to IFC Section 510, NFPA, and UL 2524, installs the amplifier, donor and interior antennas, battery backup, annunciator, and emergency power-off, and produces the test documentation the AHJ signs off on. Where a building needs both cellular and public-safety systems, we keep them separate so they don't interfere.
HOW A FACILITY GETS COVERED
Site survey and design
Tell us about the facility. We run a pre-installation signal sweep, map the dead zones across the footprint, and develop a conceptual design to code.
AHJ submission
We prepare and submit the design documentation to the Authority Having Jurisdiction and work through review and approval.
Coordination
A pre-installation meeting aligns schedule, cable pathways, equipment locations, and the other trades before any cable goes in.
Installation
Amplifiers, donor and interior antennas, cabling, and battery backup go in. Public-safety systems add the annunciator panel and emergency power-off.
Commissioning and acceptance
We configure and commission the system, run the final sweep and grid testing, and support the AHJ inspection.
Training and support
We train your designated personnel and put an ongoing maintenance plan in place.
SECTOR VS. BUYING THE HARDWARE
| Sector | Hardware only | |
|---|---|---|
| Survey and design for the footprint | ✓Pre-install sweep, heat maps, and a design sized to the whole facility | ✗A box with no survey and no design |
| Certificate of Occupancy handled | ✓Public-safety system designed to code, submitted to the AHJ, and grid-tested for sign-off | ✗You navigate code and inspection yourself |
| Commissioning and acceptance | ✓Final sweep, grid testing, and the documentation the AHJ needs | ✗No commissioning, no acceptance record |
| Maintenance and warranty | ✓Quarterly maintenance, 24/7 remote support, RMA managed for you | ✗You file your own claims and chase the manufacturer |

As early as possible. We run a signal survey once the shell is up, and designing the public-safety system early keeps it from becoming the thing that holds up your Certificate of Occupancy.
Wi-Fi doesn't carry a 911 call or a first responder's radio, and it drops devices as people move between buildings. Cellular and public-safety coverage work the way phones and radios already do, with no login.
Usually. A single system covers very large footprints, and units combine for facilities over a million square feet. We confirm the count from the survey.
It depends on the building. Many large facilities need both everyday cellular and a code-required public-safety system. We design them to coexist without interference.
