Using mobile devices in the modern workplace is standard, and users have come to expect five-bar, reliable service. While that may not always be the case in your workspace, fortunately, our cellular network engineers have developed numerous solutions to meet modern cellular connectivity needs. With so much of the nation depending on cellular connectivity, individuals and businesses alike understand the frustration of weak cell signals, dropped calls, and the inability to get online. Just as smartphone technology has evolved, so too have the solutions for keeping your business connected.

Advantages of Enhanced Indoor Cellular Coverage

Reliable indoor cellular connectivity has become essential for today’s data driven operations. Many commercial buildings continue to experience inconsistent service due to construction materials, dense interiors, and the higher frequencies required for modern 4G LTE and 5G networks.

A modern Cellular Distributed Antenna System (DAS) or hybrid in‑building wireless solution provides the ideal way to deliver consistent, high-quality coverage wherever outdoor macro signals cannot reliably penetrate. Using a strategically placed donor antenna, these systems capture and amplify carrier approved signals deep inside your facility.

Seamless, High-Quality Connectivity

A 4G LTE /5G DAS delivers uniform, high strength cellular signal throughout your building using a network of distributed antennas designed for optimal indoor performance. This ensures uninterrupted voice, data, and app connectivity, even in areas historically affected by signal loss. Consistent indoor coverage is essential for business-critical applications, IoT systems, and high-density user environments.

Comprehensive Building Wide Coverage

Radiant Networks experienced design engineering team performs detailed RF surveys to determine precise antenna placement. This ensures every system is tailored to overcome your building’s unique challenges, including thick walls, metal structures, mechanical rooms, and below grade spaces. The result is a robust, continuous blanket of cellular coverage that enhances productivity and supports modern wireless demands.

Higher Network Efficiency & 5G Performance

With the growth of 5G low-, mid-, and C‑band frequencies, indoor systems must support higher throughput, lower latency, and increased device density. Today’s advanced DAS architecture enables speeds reaching multi gigabit performance, supporting bandwidth hungry applications such as real time analytics, advanced IoT, and high-definition collaboration tools.

Multi‑Carrier, Multi‑Band Support

A properly designed system ensures all carriers operating in your region are supported. Radiant Networks delivers neutral host, multi carrier DAS solutions engineered to provide equitable access for users on not just AT&T, Verizon, and T‑Mobile, but smaller regional providers as well. This empowers your team to use their preferred carrier while maintaining optimal connectivity.

Enhanced Security & Network Protection

Traditional Wi‑Fi networks often rely on shared passwords and can present security risks. In contrast, 4G LTE /5G technologies incorporate carrier grade authentication, encryption, and SIM‑based identity management. Indoor cellular solutions extend these protections inside your facility, improving security posture for applications, devices, and mission‑critical communications.

Educational Information

What is Indoor Cellular DAS?

Indoor Cellular DAS (Distributed Antenna System) improves 4G LTE and 5G coverage inside buildings where signals are weak or blocked.

Radiant Networks Engineered DAS works by:

Capturing a strong outdoor signal via a donor antenna
Amplifying it through carrier‑approved equipment
Redistributing it indoors through a network of strategically placed antennas

The Result:
Your building receives consistent voice quality, higher data speeds, and reliable coverage everywhere, even in basements, stairwells, or shielded interior spaces.

Why Indoor DAS Matters: U.S. Code & Regulatory Requirements

Many U.S. states, counties, and cities now require in‑building radio coverage for first responders as a condition for occupancy. These systems are legally referred to as ERCES (Emergency Responder Communications Enhancement Systems) or Public Safety DAS.

National & Model Code Requirements

International Fire Code (IFC)

IFC Section 510 requires buildings above 12,000 sq. ft. or those with inadequate signals to provide two‑way emergency responder radio coverage.
Since 2009, all new buildings must include approved in‑building radio coverage per IFC guidelines.

International Building Code (IBC)

IBC Section 403.4.5 mandates in‑building emergency responder communication coverage.

NFPA 1 & NFPA 72

NFPA requires minimum radio signal strength inside all new and existing buildings. Critical areas (stairwells, pump rooms, fire command centers) must meet 99% coverage.

Local Jurisdiction Requirements

Nearly every U.S. city and county has enacted ordinances mandating in‑building radio coverage for first responders as a condition for occupancy permits.

Local regions have stricter requirements:
