It’s Time to Rethink In-Building Wireless Deployment

By Jonathan Lester, Chief Technology Officer & Senior Vice President of Product, Airwavz

Note: This blog was produced under WIA’s Innovation and Technology Council (ITC). The ITC is the forum for forecasting the future of the wireless industry. Participants explore developments in the wider wireless industry, from 5G network monetization trends and streamlining infrastructure deployment to future spectrum needs and cell site power issues. These views are not a WIA endorsement of a particular company, product, policy or technology.

Over the past several years, the economics of in-building wireless have been changing. Wireless carriers continue to invest in the venues that matter most to their network strategies, but they are also becoming more selective about where and how they participate in indoor deployments.

That evolution extends beyond new construction. As existing agreements come up for renewal, carriers are re-evaluating operating expenses and long-term investments in many previously deployed systems. For building owners, that means taking on a greater role not only in funding new indoor wireless projects, but also in maintaining, modernizing, and expanding existing infrastructure.

Rather than signaling a retreat from in-building wireless, these changes reflect an evolution in how the industry delivers indoor connectivity. As responsibilities shift, the partnerships, technologies, and deployment models that support them must evolve as well.

Building owners have become far more sophisticated in how they think about connectivity. Commercial real estate operators, healthcare organizations, universities, and hospitality providers increasingly understand that wireless infrastructure is part of the overall building experience. They are comfortable investing in technology solutions such as DAS infrastructure and neutral- host networks because they recognize the value connectivity brings to tenants, employees, patients, and visitors.

Many building owners understand the need to deploy networks inside their facilities. What they most often need help with is navigating the carrier side of the equation. A neutral-host network without a carrier-grade radio source is just infrastructure waiting to be activated. Building owners can deploy excellent indoor networks, but connecting those investments into carrier environments requires expertise, relationships, and processes that have traditionally lived elsewhere in the ecosystem.

That is becoming one of the industry’s most important roles: helping bridge the gap between building infrastructure and carrier-grade networks.

The Deployment Model Is Evolving

As building owners assume a larger role, the industry cannot simply apply yesterday’s deployment models to tomorrow’s projects.

For years, many indoor deployments naturally gravitated toward network architectures designed for the most demanding environments. That made sense when carrier-funded deployments were concentrated in stadiums, transportation hubs, convention centers, and other marquee venues. Those environments still require highly engineered, high-capacity solutions, and they always will.

Today’s market is broader. Healthcare facilities, office buildings, hotels, multifamily properties, manufacturing sites, and university campuses each present different technical, operational, and economic requirements. Treating every project as though it requires the same network architecture does not create better outcomes. It often creates unnecessary cost and complexity.

Sometimes a carrier-grade DAS deployment is exactly the right answer. In other cases, a different solution may provide the right balance of performance, scalability, and economics. The goal is not to replace one technology with another. It is to expand the toolbox.

More Tools in the Toolbox

That broader toolbox includes a range of approaches, including carrier-grade RAN connections, neutral-host architectures, and over-the-air signal sources.

Over-the-air devices have a place in certain markets and can be effective in the right environments. But they are not a universal replacement for dedicated carrier-grade radio sources.

In larger buildings, mission-critical environments, and facilities where reliability and service levels are essential, carrier-grade RAN connections provide visibility, control, and performance that over-the-air solutions are not designed to deliver. Traditional Part 90 signal booster solutions and newer Part 20 approaches each address specific use cases, but they serve different requirements than a fully integrated carrier-grade deployment.

The question is which solution best aligns with the needs of the building. That flexibility is increasingly important as the market evolves. Building owners do not need more complexity. They need deployment options that match the scale of their requirements and trusted partners who can help navigate the process.

A Partnership Model for the Next Phase of Indoor Wireless

The objective is not to shift responsibility from carriers to technology partners or from carriers to building owners. It is to create a model where each participant focuses on what they do best.

Carriers continue to manage their network and performance standards. Building owners make investments that improve the experience inside their properties. Technology partners help bridge these worlds by designing, deploying, and operating solutions that align with both business objectives and carrier requirements.

We are already seeing this model take shape. Carriers are developing new engagement approaches for trusted partners. RAN equipment providers are introducing more flexible architectures and radio source options. Building owners are becoming more informed and more engaged in the process.

That is a positive evolution for the industry.

The future of in-building wireless will not be defined by a single technology, a single deployment model, or a single company. It will be defined by an ecosystem that works together to match the right solution to the right building.
