SignalMax Hybrid Fiber DAS: Reliable 5G/LTE Coverage – Up to 500,000 sq ft

SureCall’s fiber-backed system delivers consistent signal across your entire building – no dead zones, no deployment headaches and full support for all major carriers with no retransmission agreements required.

Finally, reliable 5G and LTE coverage that reaches every nook and cranny

Most commercial buildings weren’t built with cell signal in mind.

Distance from towers, dense construction materials, metal roofs and low-emissivity glass block incoming signal. Basements and interior rooms go dark. And standard boosters – with their short range and coaxial cable – just don’t cut it.

That’s where SureCall’s SignalMax Fiber DAS comes in.

It’s a hybrid-fiber distributed antenna system (DAS) that delivers strong, reliable 5G and LTE coverage from every major carrier – and pushes it deep into your building using fiber, not coax.

That means:

Uniform coverage across your layout – from 50,000 to 500,000 sq. ft.
No retransmission agreements. No sky-high engineering fees. No dead zones.
A modular system you can deploy faster – and rely on longer

Fiber backbone, not coax – more coverage than Passive DAS, less cost than Active DAS

Passive DAS relies on coaxial cable, which degrades signal strength over distance. That limits coverage, causes dropouts, and leads to messy workarounds like booster stacking.

SignalMax is different.

It uses single-mode fiber optic cable to move signal across your building – with virtually zero signal loss.

That fiber backbone delivers:

Strong, reliable performance in every wing, floor and zone
Easy expansion as coverage needs grow
Higher output at each remote unit, outpacing Passive DAS

But it’s not just better than coax – it’s a smarter alternative to Active DAS too.

Active DAS requires extensive engineering, individual carrier coordination, and lengthy deployments.

SignalMax skips all that. It’s FCC Part 20 certified and pre-approved for Verizon, AT&T, and T-Mobile. As SureCall puts it, it “costs only cents per square foot of coverage,” giving you enterprise-grade connectivity without the complexity.

The perfect middle-ground between Active and Passive.

Built for real-world installs – from warehouses to hospitals to campuses

Modular coverage: Add up to 3 Remote Units and 16 indoor antennas per unit
Extended Range Tech™: Boosts signal at the source for max clarity and speed
Remote control: Use the mobile app on-site or monitor 24/7 with SureCall Cloud
Rugged hardware: IP66-rated Master Unit handles dust, heat and cold without fail

Not sure how a SignalMax deployment will actually cover your building?

No problem. With SureCall, you’ll get iBwave designs with predictive coverage maps, so you know exactly what you’re getting before install begins. Smarter planning for complete coverage.

SignalMax Solves These 5 Problems

Dead zones in basements, interior rooms and upper floors

Modern materials kill signal. SignalMax captures strong outdoor coverage and pushes it deep inside – to every wing, hallway and stairwell.

Unreliable connectivity that disrupts operations

No more buffering video calls or dropped warehouse comms. SignalMax ensures reliable 5G/LTE throughout the building.

Coverage limits of standard boosters

Most boosters top out at 25,000 sq. ft. SignalMax starts at 50,000 and scales up to 500,000+ with additional remote units.

High cost and complexity of Active DAS

Active DAS is slower to deploy and expensive, with custom designs, long lead times and deep infrastructure costs. SignalMax delivers enterprise coverage without the overhead.

Carrier headaches – solved

SignalMax is FCC Part 20-certified, pre-approved for all major carriers, like Verizon, AT&T, T-Mobile and UScellular – no retransmission agreements to sign, no red tape, no users left out.
