Millimeter Wave Broadband

Key Takeaways

• Verizon's mmWave accounts for 2.2% of its speed tests in H2 2025
• AT&T's mmWave usage is only 0.2%; T‑Mobile negligible
• Effective range stays under 500 ft, far below theoretical half‑mile
• mmWave benefits dense urban zones but can't replace broader coverage bands
• C‑Band also shows half‑mile practical range despite two‑mile potential

Pulse Analysis

The resurgence of millimeter‑wave (mmWave) technology is a direct response to the ever‑growing demand for ultra‑fast mobile data. After an early hype cycle in 2000, Verizon’s recent deployment of 28 GHz spectrum—originally acquired from Straight Path and XO Communications—has finally found a measurable foothold. Ookla’s RootMetrics study, which blends crowdsourced speed tests with on‑the‑ground measurements, reveals that 2.2% of Verizon’s tests now rely on mmWave, a modest yet significant uptick that validates the carrier’s long‑term vision of competing with fiber and cable in high‑density corridors.

Technical realities, however, keep mmWave firmly in the role of a hotspot enhancer. The study shows most successful connections occur within 500 feet of a base station, a stark contrast to the half‑mile range often quoted in promotional material. This short reach mirrors findings for the newer C‑Band (3.7‑4.2 GHz), which, despite a theoretical two‑mile radius, delivers optimal speeds only within a half‑mile. Lower‑frequency bands like 700 MHz still dominate wide‑area coverage but lack the bandwidth to support multi‑gigabit streams, underscoring the trade‑off between range and capacity that operators must balance.

For the industry, these insights reshape investment priorities. Carriers are likely to densify mmWave nodes in downtown cores, stadiums, and transit hubs where traffic spikes justify the cost of dense antenna placement. At the same time, the modest adoption rates—especially AT&T’s 0.2% and T‑Mobile’s near‑zero—signal that broader 5G strategies will continue to lean on mid‑band and low‑band spectra for reliable coverage. Understanding these dynamics helps telecom executives allocate capital efficiently, regulators assess spectrum policy, and enterprises plan for the next wave of mobile‑first applications that demand both speed and proximity.
