Cell service that holds up on event day.
Signal looks fine in an empty arena. Then thousands of phones connect at once. We design indoor cellular for peak crowds across seats, concourses, halls and back-of-house.
What it looks like day to day.
A typical scenario based on the environments we work in, not a specific customer.
- Fans can't post, pay or share during events
- Mobile tickets and point-of-sale slow down at peak
- Staff phones struggle in crowds
- Exhibitors complain about service in the halls
Crowds need capacity, not just coverage.
Outdoor towers can't serve thousands of phones in one bowl. An indoor system splits the venue into many smaller zones so each one has its own capacity.
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.
Plan for the peak
Seating, concourses, halls and how crowds move.
Design the zones
Many small coverage zones sized for crowd density.
Coordinate with carriers
Approvals and capacity planning with each carrier.
Test before the big event
Verify under real load when the project calls for it.
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.
Fans stay connected
Posting, paying and sharing work at peak.
Operations keep moving
Ticketing and point-of-sale stay fast.
Revenue protected
Mobile ordering and payments go through.
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
- Arenas and stadiums
- Convention and exhibition centers
- Large hotels and resorts
Something else may fit better

The design decisions, the end-to-end path and how the result is tested.
Ingress, seated periods, intermission, egress, and exhibit activity place different demand in different zones.
Design decisions
| Design decision | What we need to understand | How we engineer it |
|---|---|---|
| Density model | Estimate devices, carrier share, concurrency, traffic mix, and movement by zone. | Create sector capacity and antenna patterns around event demand. |
| Source capacity | Confirm carrier baseband, small-cell, or other dedicated capacity contributions. | Feed the DAS with enough capacity for the planned sectors. |
| Event change | Document stages, curtains, booths, media, temporary structures, and operating modes. | Revalidate patterns and load for representative configurations. |

Antennas do not create capacity. Sector count, source resources, carrier participation, RF isolation, and user distribution determine the usable result.
How the result is tested
- Load test Exercise planned user and traffic volume by carrier and sector.
- Ingress test Measure ticket, message, call, and data performance during arrival.
- Sector test Verify dominance, overlap, interference, and handoff between venue zones.
- Uplink test Measure spectator upload and operational traffic under peak conditions.
- Configuration test Repeat for representative stage, booth, curtain, and seating layouts.
- Event-operations test Confirm alarms, dashboards, carrier escalation, and post-event reporting.
