How It Works - Numinetech

Why do you need reliable, high quality wireless networks today?

With most mobile activity now happening indoors, reliable cellular coverage has become a business necessity. Poor indoor reception leads to dropped calls, slow data, and lost productivity—issues often caused not by mobile networks, but by the buildings themselves.

What Is In-Building Wireless (IBW) / DAS?

In-Building Wireless (IBW) or Distributed Antenna Systems (DAS) are engineered networks of antennas, amplifiers, and cabling that extend and strengthen cellular signals inside buildings. These systems capture outdoor signals, route them through a distribution network, and rebroadcast them indoors to eliminate dead zones.

Why Indoor Coverage Is Weak

Modern building materials—such as energy-efficient glass, reinforced concrete, metal framing, and layered insulation—block or weaken radio waves. Urban density, high-rise clusters, and distance from cell towers further degrade signals. As 5G networks move to higher frequencies, signal penetration challenges increase, making dedicated IBW systems essential for reliable indoor coverage.

Why You Need IBC Systems

A clear sign of poor indoor coverage is when mobile performance drops indoors but improves outdoors. Persistent call failures, slow downloads, or connectivity gaps indicate the need for an IBW solution. From corporate offices and hospitals to campuses and industrial sites, IBW solutions enhance productivity, safety, and user experience — transforming connectivity from a convenience into a strategic business advantage.

Benefits & Additional Advantages

Reliable communications for all users

Employees, tenants, visitors, and devices all get continuous connectivity indoors.

Boost to building value

Strong indoor connectivity is increasingly expected by tenants, and buildings with good signal infrastructure can command higher lease premiums or resale value.

Future-proofing & regulatory readiness

As regulations and infrastructure demands evolve, a robust IBW setup keeps a site ahead of compliance and performance issues.

Operational efficiency

Spontaneous meetings, mobile working, IoT, tablets, voice over LTE (VoLTE) and other connected services perform better when the signal is seamless indoors.

In-building wireless is far more than a convenience; today, it is an infrastructure necessity. Smart organisations and facility owners recognise that ensuring strong indoor cellular coverage is no longer optional, but fundamental investment to ensure productivity, safety, tenant satisfaction and competitive advantage.
