Voice, messaging, and safety
Restore reliable mobile communication for employees, visitors, contractors, and facility teams in offices, stairwells, parking areas, basements, and shielded spaces.
Public Cellular & DAS
Bring the carrier network inside the building.
Modern glass, concrete, steel, distance from a tower, and indoor geometry can turn usable outdoor service into dropped calls and dead zones. Nettelix measures the problem, selects the right in-building coverage architecture, coordinates deployment, and proves the result across the areas that matter.
Multi-carrier strategySupport employees, visitors, contractors, and critical workflows—not only one carrier.
Right-sized architectureCompare smart signal boosters, active DAS, small cells, and hybrid public/private designs.
Measured acceptanceValidate coverage and usable service after installation rather than assuming equipment equals outcome.
Where coverage breaks down
Indoor cellular is a building problem, a carrier problem, and an operating problem.
A weak-signal complaint rarely tells you enough to specify a solution. We map the carriers, bands, spaces, users, and workflows affected—then distinguish an isolated coverage gap from a facility-wide design issue.
Cellular-dependent workflows
Support mobile apps, tablets, payment devices, building systems, IoT gateways, and carrier-connected equipment that cannot rely exclusively on enterprise Wi-Fi.
Another path when Wi-Fi fails
Indoor cellular provides independent access for communications and operations when local LAN or internet infrastructure is impaired.
Architecture choices
Not every building needs legacy DAS.
Nettelix compares coverage models by facility size, carrier requirements, signal source, bands, construction, growth, deployment speed, economics, and the possible future role of private cellular.
| Solution path | Where it fits | What must be evaluated |
|---|---|---|
| Smart signal booster | Smaller or targeted areas with usable donor signal outside the building | Available carrier signal, supported bands, antenna isolation, coverage area, and legal network-safe operation |
| Active DAS | Larger buildings, multi-floor facilities, campuses, and repeatable multi-carrier coverage | Donor source, fiber or structured cabling, radio distribution, capacity, carriers, commissioning, and expansion |
| Small cells | Locations requiring a carrier-provided indoor radio source or additional capacity | Carrier participation, backhaul, approvals, design responsibilities, operating ownership, and lead time |
| Hybrid public + private cellular | Sites that need public carrier coverage now and may add private LTE/5G for operational applications | Shared distribution infrastructure, spectrum, private core, device roadmap, support, and staged activation |
Product breadth without tunnel vision. Nettelix may deploy technologies from Nextivity and other qualified manufacturers, but the recommendation begins with the building and business requirements. We do not make every coverage problem fit one vendor.

Common environments
Designed for the places signal struggles.
We plan indoor cellular around the real operating environment and the people who depend on it.
Offices & high-risesLow-E glass, interior cores, parking, elevators, and mixed-carrier occupants.
Warehouses & factoriesLarge footprints, metal racks, equipment, yards, and operational mobile devices.
Healthcare & senior livingDense construction, clinical workflows, staff mobility, patients, and visitors.
Hotels, retail & venuesPublic-facing coverage, high user turnover, peak demand, and brand experience.
Data centersShielded rooms, secure operations, device restrictions, and resilient communications.
Campuses & parkingMultiple structures, transition spaces, below-grade zones, walkways, and outdoor edges.
