Wireless Infrastructure By the Numbers: 2025 Key Statistics

In today’s always-on world, most Americans rarely venture far without their smartphones. Beyond the handset, a growing ecosystem of connected devices—tablets, smartwatches, laptops, and vehicle infotainment systems—plays a constant role in daily life. All of it runs on the indispensable backbone of wireless infrastructure, quietly enabling continuous connections to family, friends, colleagues, customers, and partners.

In addition to providing always on mobile access, the deployment of 5G enabled by this infrastructure has brought about a home broadband revolution with more than 14 million households now connected via Fixed Wireless Access – creating competition and improving affordability for consumer home internet services. Wireless infrastructure is also an important part of the AI infrastructure stack. As AI becomes more deeply embedded in apps and services, these devices are evolving beyond simple connectivity tools. They are shifting toward intelligent, context-aware assistants capable of anticipating questions, streamlining decisions, and delivering personalized insights the moment they are needed – powered by wireless connectivity and the infrastructure that enables it.

For the fourth year, WIA’s Infrastructure by the Numbers report provides a comprehensive analysis of the U.S. wireless infrastructure sector, covering purpose-built cellular towers, macrocell sites, indoor and outdoor small cells, annual infrastructure investments, and the American workforce sustaining this essential industry.

In 2025, the U.S. cellular industry invested more than $10.2 billion in expanding network capacity and coverage, excluding expenditures on spectrum, maintenance, and ongoing operations. Operating expenses for U.S. cellular networks reached nearly $54.7 billion in 2025. In total, wireless infrastructure investments—including construction, maintenance, and operations—amounted to nearly $65 billion.

The following key statistics show the strength of the U.S. wireless infrastructure industry at the end of 2025:

• 158,500 purpose-built cellular towers were in operation;
• 254,850 macrocell sites, not including small cells, were in operation;
• 198,100 outdoor small cells were in operation;
• And 830,350 indoor small cell nodes were in use, including distributed antenna systems (DAS), small cells, private CBRS networks, and mmWave and other licensed frequency bands.

The deployment and operation of wireless infrastructure drives significant employment across the U.S. This year’s report shows an estimated 342,350 full-time workers or equivalents were engaged in building, maintaining, and operating the nation’s cellular networks.

With mobile video, AI-powered applications, hybrid workplace connectivity, and ever-growing mobile bandwidth consumption on the rise, the demand on wireless infrastructure is set to grow in the coming years. Expanding the colocation of more advanced and efficient network equipment will help meet increasing bandwidth needs while enhancing economic viability and minimizing environmental impact.
