DAS Installation Services for New Construction Projects in Orlando

Orlando's new-construction pipeline is unusually balanced across hospitality (the I-Drive and Disney-adjacent corridor), healthcare (AdventHealth, Orlando Health, Nemours), and Lake Nona's growing medical-and-tech campus. JB Technologies designs distributed antenna systems for these vertical mixes, building around the donor-signal patterns of a flat-terrain metro served by macro sites scattered between OIA, Downtown, and the SR-417 corridor. Lightning density in Central Florida is among the highest in North America, which informs every grounding and surge-protection decision we make.

Local context, Orlando, FL

Central Florida sees roughly 25-30 thunderstorm days per year, more lightning-flash density than almost anywhere in the contiguous U.S., which makes proper bonding and surge protection on every donor antenna a true life-safety concern, not a checklist item; we spec dual-stage PolyPhaser-type protection and dedicated ground rings on Orlando installs rather than relying on building steel alone. The hospitality stock along International Drive is dominated by long, low-rise convention hotels whose interior corridors run hundreds of feet and need careful indoor-antenna spacing to stay above -85 dBm RSRP. AdventHealth and Orlando Health campuses have shielded imaging and surgical suites that demand dedicated branches. Permits flow through the City of Orlando Permitting Services on the standard low-voltage track, and Orange County's growth around Lake Nona has stretched some macro-site spacing wider than the carriers prefer, occasionally driving active head-end choices on otherwise passive-friendly buildings.

What is DAS?

A Distributed Antenna System (DAS) is an engineered network of indoor antennas that distributes commercial cellular signal throughout a building so that tenants, employees, and visitors get reliable voice and data coverage on Verizon, AT&T, and T-Mobile. DAS solves the in-building coverage problem in two architectures. Passive DAS uses a donor antenna on the roof feeding a bi-directional amplifier and a coax-and-splitter distribution grid, cost-effective for buildings under roughly 150,000 square feet with a usable outdoor donor signal. Active DAS converts RF to digital at a head-end and distributes over fiber to remote units, scaling cleanly to multi-million-square-foot venues and supporting all major carriers through carrier-grade signal sources. When the outdoor donor is strong and the building is mid-sized, a single-carrier CEL-FI QUATRA deployment is often the right answer; when the donor is weak, the building is large, or true multi-carrier parity is needed, an active DAS is the durable choice.

Where DAS makes sense

DAS is owner- and tenant-driven, it is the answer to "why does my phone drop calls inside this building?" rather than a building-code mandate. Typical DAS candidates:

1. Large floor plates, offices, hospitals, and campuses over roughly 50,000 sq ft where a single booster cannot cover the area.
2. Dense concrete or steel construction, hardened cores and rebar-heavy slabs attenuate cellular signal 15 to 25 dB.
3. Impact-rated or low-E glass, modern energy-efficient and hurricane-impact glazing attenuates PCS and AWS bands 10 to 18 dB.
4. Multi-carrier requirements, tenants and visitors on Verizon, AT&T, and T-Mobile all need parity coverage.
5. Below-grade and parking levels, basements, parking decks, and tunnels where macro signal does not penetrate.
6. Healthcare facilities, nurse-call workflows, BYOD clinical apps, and patient-experience requirements.
7. Hotels and mixed-use towers, in-room and amenity-floor cellular is a guest-experience expectation.
8. Warehouses and distribution centers, metal-clad envelopes and dock-door geometry that block macro signal.
9. Higher-education buildings, libraries, residence halls, and student centers with dense user counts.
10. Stadiums, arenas, and conference venues, capacity-driven deployments, not just coverage.

Typical system costs.

DAS pricing varies with building size, donor-signal strength, carrier mix, and design topology. Two rough ranges hold across most commercial work:

Installed Cost Ranges

• Passive DAS, $0.75 to $1.50 per square foot for single-carrier or limited multi-carrier deployments with a clean donor signal, typical of mid-sized offices and mid-rise residential.
• Active multi-carrier DAS, $2.50 to $5.00 per square foot, driven by remote-unit count, fiber backbone length, carrier signal-source coordination, and AHJ requirements. Hospitals, stadiums, and campus deployments live in this range.
• RF site survey and design package, typically $1,500 to $5,000 depending on building footprint and the number of carriers in scope.
• Factors that drive cost:
  • Donor signal strength, weak outdoor RSSI may force a tower-mounted amplifier, an off-air bi-directional amp upgrade, or a small-cell signal source.
  • Building materials, concrete, low-E glass, impact glazing, and metal cladding each shift the design.
  • Carrier mix, single-carrier QUATRA units are cheaper than tri-carrier active head-ends, and each added carrier requires its own Letter of Authorization.
  • Retrofit vs new construction, pulling fiber and coax in finished spaces costs materially more than rough-in during the shell stage.

Permitting and Carrier Coordination

• Electrical and low-voltage permits, required in most jurisdictions for head-end power and cable distribution.
• Carrier Letters of Authorization (LOAs), active DAS using signal sources from Verizon, AT&T, or T-Mobile requires per-carrier LOAs and RF-emissions disclosure under FCC Part 90, Part 22, and Part 24.
• FCC signal-booster registration, consumer-class boosters must be registered with the operating carrier; commercial Part 20.21 systems are coordinated upfront.

Commissioning and Ongoing Support

• Commissioning sweeps, downlink and uplink RSSI measured at design points, exported to the building owner and the AHJ when applicable.
• Annual coverage verification, recommended after major tenant fit-outs, antenna relocations, or carrier band-plan changes.
• Warranty and remote monitoring, QUATRA and most active DAS head-ends ship with cloud monitoring; JBT maintains active alarms through a service agreement.

Key Takeaways

• Plan during shell construction, rough-in for fiber and coax pays back many times over versus a finished-space retrofit.
• Match the topology to the building, passive for smaller buildings with good donor, active for large or multi-carrier requirements.
• Confirm carriers early, the carrier mix dictates equipment selection, LOAs, and design timeline.
