American Tower, a wireless infrastructure company, identified four catalysts it expects to support investment in wireless networks over the next decade, citing record US wireless data consumption of 159 trillion megabytes in 2025. The growth outlook, including roughly 800 MHz of additional mobile spectrum expected from 2027, is a projection and company view rather than a shipped network capability.
Why it matters
Wireless traffic growth is pushing carriers to add equipment to existing cell sites and to increase site density where demand is highest. AI-powered devices, agents, connected vehicles and robotics are expected to generate persistent, uplink-intensive traffic that could deepen that investment cycle beyond traditional forecasts.
US wireless data consumption reached a record 159 trillion megabytes in 2025, up more than 20% from the prior year. American Tower expects roughly 800 MHz of additional mobile spectrum to be deployed beginning with upper C-band in 2027, though the allocation and rollout schedule remain projections.
The players
American Tower
A major owner and operator of wireless communications infrastructure, including cell towers that carriers lease to deploy networking equipment.
CTIA
The trade association representing the US wireless communications industry, whose traffic and demand projections are cited in the company's outlook.
The details
Carriers are responding to heavier traffic by adding radio equipment to existing cell sites and by increasing cell site density in high-demand areas, which means more antennas closer to users. The industry is also moving toward more distributed network architectures that rely more heavily on edge computing, where processing happens nearer the device rather than in distant data centers.
Timeline
2025: US wireless data consumption hit a record 159 trillion megabytes.
2027: Deployment of upper C-band spectrum, roughly 800 MHz of additional mobile spectrum, is expected to begin.
2032: CTIA projects total wireless demand to grow fourfold.
2034: CTIA expects AI traffic could account for nearly one-third of broadband traffic.
The Tech Race
CTIA's projection of fourfold wireless demand growth by 2032 sets the baseline that American Tower extends by arguing AI traffic could push investment beyond traditional forecasts. The competitive question is whether carriers can add spectrum and site density fast enough to keep pace with that demand.
Users are likely to see the effects of this buildout as more cell sites and added equipment at existing sites in dense areas, though the stub gives no timeline for consumer-facing changes. The projected spectrum and capacity additions are not yet available to users, and their pricing and rollout dates are unannounced.
The takeaway
The central trajectory is that wireless demand, and increasingly AI-generated traffic, is driving denser networks and more distributed architectures. Watch for the start of upper C-band deployment in 2027 and CTIA's 2032 and 2034 traffic projections as checkpoints on whether this investment cycle holds.
What happens next
Upper C-band spectrum deployment is expected to begin in 2027 as the roughly 800 MHz of additional mobile spectrum comes online.
