How to Improve In-Building Cellular Connectivity with DAS

Is it time for a better in-building cellular network? Today, secure and reliable in-building wireless connectivity isn’t an option but an operational necessity — and more leaders are turning to wireless DAS to meet that need. Here’s what you should know about in-building DAS and why it’s quickly becoming an operational must-have for organizations of all types.

Why Traditional In-Building Cellular Networks Fall Short

Whether you manage a retail business looking to ensure a premium and functional in-store experience, a hospital where concrete construction can often block signals, a school where security requires constant connectivity, or any number of other scenarios, the need for fast, high-bandwidth in-building wireless is a constant for pretty much every type of organization.

But even as that need grows, the challenges of traditional cellular networks continue to stubbornly block the way. The fact is, for many businesses and public organizations, technology is struggling to keep up with the ever-increasing demand for seamless and secure in-building cellular connectivity.

Even more advanced versions of those networks, like 5G, are prone to interference from external sources, and coverage gaps from physical barriers — think big, concrete walls or other hard-to-penetrate materials in hospitals, malls, warehouses, and so many other everyday settings.

These dead zones often extend not only into remote spots like stairwells, basements, and parking garages, but also high-traffic spots frequented by customers and employees alike, stifling standard connectivity as well as the ability to freely and seamlessly roam throughout all of a facility’s spaces.

Traditional cellular networks also suffer from congestion issues — slowing and dropping when a certain number of people seek to access them from the same physical space — and signal interference from multiple users.

Why DAS is the Future of In-Building Cellular Networks

More and more, these kinds of service gaps and outages simply aren’t acceptable. More than dropped calls, network outages can prove disruptive in a way that not only jeopardizes sales and minute-by-minute operations but also the security of assets and the personal safety of customers, clients, employees, and vendors.

The result is a need for better in-building wireless connectivity. And that’s where DAS comes in. As we’ve learned, DAS — an abbreviation of distributed antenna system — is a method of providing wireless coverage across a network of separate, strategically placed antennas.

By spreading out the signal in this way, wireless DAS helps ensure consistent, reliable in-building cellular coverage in a way that simple 5G connectivity or Wi-Fi access points can’t achieve on their own. The result? Much more uniform signal distribution throughout all of a building’s spaces, including underground and other hard-to-reach areas.

How DAS Overcomes the Limits of Traditional In-Building Cellular

Cellular DAS systems can overcome the limitations of traditional in-building wireless networks in a number of important ways. Specifically, they can help:

• Eliminate disruptive dead zones, signal conflicts, and coverage gaps with strategic antenna placement

• Reduce outside interference for more stable network performance

• Convert cellular signals to expand their reach and ability to penetrate certain materials

• Expand capacity to handle a huge amount of connections simultaneously without suffering from congestion issues

• Empower network management from a centralized space for easier control, access, and troubleshooting

• Provide uninterrupted connectivity during emergencies with built-in redundancies

• Enable easy, seamless roaming between a building’s different access points without drops or delays

How Does DAS Work?

In-building DAS improves upon traditional cellular networks by combining a dedicated signal source (such as an external antenna or transceiver base station) with a distribution system of internal antennas. This has the effect of reproducing a series of actual cell towers in various spaces within a facility — but all under its roof, and dedicated to that building’s service.

So, the difference between in-building DAS and traditional cellular networks is one of amplitude and local access — it’s like a miniaturized version of that network, available for exclusive use.

And the difference between DAS and Wi-Fi is one of reach, capacity, and security, where the individual wireless access points of a Wi-Fi system are bound to specific spaces and usage limits. In addition, a DAS system’s centralized controller more intelligently manages bandwidth while eliminating interference for more stable and seamless connectivity.

The result? For buildings that are large, high-density, or with hard-to-penetrate materials, DAS networks don’t just improve on traditional cellular coverage but offer a new level of quality and reliability. For businesses and any other type of public organization looking to more fully embrace digital capabilities — or simply to gain the full benefits of 5G connectivity — in-building DAS is a game-changer.
