Market Overview  

The in-building wireless market is experiencing dynamic growth, driven by the increasing need for robust connectivity solutions in high-traffic environments. While the Distributed Antenna System (DAS) market is currently 14X larger than the private 5G market, the gap is expected to narrow significantly by 2029. Private 5G networks are projected to grow at a Compound Annual Growth Rate (CAGR) of 63%, compared to DAS’s more modest 21%. By 2029, total revenue for private 5G is forecast to reach US$19.4 billion, while DAS will generate US$44.2 billion within the same time frame.

This growth can be attributed to the demand for higher-performance connectivity in environments like airports, stadiums, and manufacturing facilities. While DAS continues to dominate in areas requiring broad signal coverage, private 5G is poised to meet the growing need for more customized, secure, and high-performance connectivity, particularly in enterprise applications like the Internet of Things (IoT) and automation.


“Greenfield sites are expected to witness a surge in private 5G deployments, while DAS will continue to be the preferred choice for enterprises familiar with its established technology, despite its limitations in supporting future advancements like Millimeter Wave (mmWave). This trend signals a shift toward more advanced connectivity solutions that can meet the evolving demands of modern applications.” – Sam Bowling, Analyst at ABI Research


 

The Competitive Landscape Between DAS and Private 5G

DAS remains a crucial solution for providing reliable coverage in venues with dense user populations. It excels in distributing signals across large areas, ensuring consistent connectivity for voice and basic data applications. However, as demand for bandwidth-intensive applications increases, such as real-time data analytics, robotics, and Augmented Reality (AR), private 5G networks are emerging as a superior alternative.

Private 5G’s ability to deliver ultra-low latency, high throughput, and massive scalability makes it an ideal choice for sectors like manufacturing, where real-time performance and security are paramount. As enterprises look to leverage technologies like the IoT and automation, private 5G offers a flexible and future-proof solution that traditional DASs cannot match.

Key Trends Shaping In-Building Wireless Connectivity

Several key trends are driving the evolution of in-building wireless systems. Open Radio Access Network (RAN) is enhancing network flexibility by enabling businesses to integrate various vendors and customize their connectivity solutions. At the same time, Artificial Intelligence (AI) and Machine Learning (ML) are optimizing network performance in real time, allowing for dynamic adjustments based on fluctuating demand.

Network slicing within private 5G systems is also gaining traction, allowing enterprises to allocate resources more efficiently by prioritizing critical applications like IoT or real-time data processing. Additionally, the rise of neutral host networks—such as Nokia’s Radio Frequency Conversion (RFC) box—is improving connectivity in large venues by offering shared infrastructure that benefits multiple service providers, reducing costs and enhancing reliability. These trends are transforming in-building wireless networks to meet the growing demands of modern businesses.

Challenges and the Path Forward

One of the significant challenges in the in-building wireless market is the inability of many existing buildings to support modern connectivity solutions. As the demand for higher bandwidth and low latency increases, telecommunications providers must adapt to diverse building structures and architectural designs. Implementing effective solutions that can scale and accommodate evolving connectivity needs will be crucial for operators aiming to stay competitive in the marketplace.

Additionally, educating enterprises about the benefits of private 5G networks, such as enhanced security and improved performance, will be essential to driving adoption and encouraging investment in next-generation connectivity solutions.

Key Companies

Conclusion

The in-building wireless market is undergoing significant transformation as private 5G and DAS solutions compete to meet the evolving demands of high-traffic environments and enterprise applications. While DAS remains a reliable solution for broad coverage, private 5G is set to cut into DAS’s market share, driven by its flexibility, performance, and ability to support next-generation applications. As the market continues to evolve, the integration of Open RAN, AI, ML, network slicing, and neutral host networks will play a critical role in shaping the future of in-building wireless systems.
