80%

of 911 calls are made from cellphones.

As more organizations adopt digital transformation strategies, the need for high-capacity, reliable wireless connectivity will continue to expand, making in-building wireless connectivity a crucial part of future building designs and retrofits.

As a result, the global in-building wireless market has grown rapidly, surpassing $11 billion in 2023 and projected to reach nearly $25 billion by 2030, with a compound annual growth rate (CAGR) of around 12%. This includes 4G and 5G public cellular networks, as well as private wireless networks that enterprises are deploying to better manage their connectivity. Cellular connectivity is complementary to Wi-Fi connectivity, and businesses are increasingly using both technologies to manage internal and external communications.

This growth is driven by several factors:

Rise in Mobile Device Usage: The proliferation of smartphones, IoT devices, and connected applications inside commercial and residential buildings has necessitated robust wireless solutions to maintain network performance.
Demand for High-Speed Data: The adoption of 5G and the demand for faster data speeds are fueling investment in advanced in-building wireless solutions.
Enterprise Connectivity Needs: Modern businesses rely heavily on continuous connectivity to maintain operations, optimize workflows, and provide services, making in-building connectivity critical in corporate environments. Increasingly, enterprises are deploying private wireless systems to better manage their own networks.
Smart Buildings: The integration of automation, security, and smart systems in buildings has led to the need for more advanced wireless infrastructure.

Key Technologies Supporting In-Building Wireless

A variety of technologies make up the in-building wireless ecosystem, each playing a vital role in providing robust coverage and capacity within structures:

Distributed Antenna Systems (DAS): DAS is one of the most common IBW technologies, used to extend cellular coverage throughout large buildings. It involves a network of spatially separated antennas connected to a common source, enhancing signal strength in hard-to-reach areas such as basements and stairwells.

Small Cells: Small cells are low-power cellular nodes that provide coverage in specific locations where signals are weak or capacity is needed. They are highly efficient in high-density environments like stadiums, offices, and shopping malls.

Private Networks: U.S. mobile operators are increasingly offering cellular connectivity to customers on private networks. A private cellular network enables an enterprise to use the same technology but use of the network is limited to a specific group of people, employees and/or devices. A private cellular network may be interconnected to commercial cellular networks.
