Cell service as a building amenity for every tenant.
Window offices work, interior suites and lower floors don't, and every tenant tries its own fix. A shared indoor system covers the whole building once.
What it looks like day to day.
A typical scenario based on the environments we work in, not a specific customer.
- Tenants complain about service in interior suites
- Some tenants install their own boosters
- Prospects ask about signal during tours
- Elevators, lobbies and parking are dead zones
One building, one system.
Coverage in a tower varies by height, core and orientation. Piecemeal tenant fixes cause interference and don't cover common areas. A building-wide system is planned once and grows with the tenants.
How we fix it.
Indoor cellular (often called DAS) brings AT&T, Verizon and T-Mobile signal inside your building and spreads it where people are, so calls, texts and data just work.
Assess the building
Signal by floor, core, lobby, elevators and parking.
Design a shared system
One platform sized for every floor, with room to expand.
Coordinate with carriers
Signal source and approvals handled for each carrier.
Install floor by floor
Minimal disruption to occupied suites.
Designs start from your floor plans and each carrier's signal. We survey on site when the building calls for it.
What's different after.
An amenity that leases
Coverage becomes part of the building's value.
No rogue boosters
One engineered system instead of tenant fixes.
Common areas covered
Lobbies, elevators and parking included.
Where this works, and where something else fits better.
We recommend what solves the problem, even when it's a different solution.
A good fit for
- Multi-tenant office towers
- Mixed-use buildings
- Owners planning renovations or repositioning
Something else may fit better
- A single small tenant may be better served by a smaller system for its own suite

Technical detail
The design decisions, the end-to-end path and how the result is tested.
The technical design and commercial operating model must both support multiple carriers and changing tenants.
Design decisions
| Design decision | What we need to understand | How we engineer it |
|---|---|---|
| Carrier participation | Identify tenant carrier mix, source options, approval, and contribution paths. | Build a supported roadmap rather than promising all carriers by assumption. |
| Common zones | Prioritize lobby, elevators, amenities, management, parking, and tenant floors. | Create measurable base-building service and documented tenant-extension rules. |
| Lifecycle model | Define ownership, monitoring, access, maintenance, upgrades, and tenant changes. | Operate the DAS like a building system with accountable records. |

A shared physical platform does not guarantee immediate participation by every carrier. Commercial and technical onboarding must be managed explicitly.
How the result is tested
- Tenant-floor test Measure perimeter, interior, core, and meeting areas by carrier.
- Vertical test Walk elevators, stairs, lobbies, and floor transitions.
- Common-area test Verify amenities, management, loading, and parking zones.
- Capacity test Observe service during planned occupancy and peak tenant demand.
- Alarm test Trace source, headend, remote, power, fiber, and antenna faults.
- Change test Revalidate after major partition or tenant construction changes.
