Analyst Dean Bubley challenges CTIA over rural 5G spectrum utilization gaps

The tension between shared spectrum models like CBRS and exclusive licensed bands directly impacts how streaming video reaches underserved markets. If major carriers continue to leave rural spectrum fallow in favor of satellite-based edge cases, the industry may face a prolonged digital divide that limits high-bandwidth video consumption in remote areas. This conflict challenges the traditional terrestrial deployment model and suggests that regulatory bodies like the FCC may shift toward more aggressive sharing requirements. Watch for whether the FCC ties future 6G spectrum auctions to stricter build-out requirements or mandatory sharing protocols for existing rural licenses.

The CBRS band has become a flashpoint in the broader debate over how the United States allocates mid-band spectrum for wireless broadband. The FCC's 2020 auction of Priority Access Licenses in the 3.5 GHz band drew participation from cable operators and smaller carriers, but major mobile operators including Verizon and AT&T have largely avoided deploying CBRS at scale, leaving the band underutilized relative to its 150 MHz of available capacity. Meanwhile, Telstra completed a CBRS-style shared spectrum trial in Australia's 3.5 GHz band in early 2025, demonstrating that shared models can coexist with incumbent services when governance frameworks are clearly defined. The contrast between international shared-spectrum experiments and US carrier resistance underscores the tension Bubley identifies between lobbying positions and actual deployment behavior.

Regulatory momentum around spectrum sharing has intensified on multiple fronts. The NTIA's National Spectrum Strategy, published in late 2023, identified dynamic sharing as a core mechanism for freeing federal spectrum for commercial use, and the FCC's 2025 Notice of Proposed Rulemaking on the upper 6 GHz band proposed a shared-access framework that would extend CBRS-style coordination into frequencies critical for 6G planning. CTIA has pushed back, arguing that shared models create interference risks that undermine investment certainty. Vodafone and Orange jointly endorsed shared spectrum frameworks in their 2025 European policy submissions, signaling that major operators outside the US are willing to accept coordination-based access when it accelerates coverage goals. This transatlantic divergence strengthens the case that US carrier opposition is driven more by competitive strategy than technical limitation.

On the technical side, independent testing has begun to quantify the performance trade-offs of shared versus exclusive spectrum in rural environments. A 2025 study by the Wireless Infrastructure Association found that CBRS-based rural deployments delivered median throughput of 85 Mbps at cell ranges exceeding 10 kilometers, comparable to licensed mid-band performance in low-density areas. Open RAN implementations in these deployments reduced per-site capital costs by an estimated 30 percent relative to traditional single-vendor stacks, according to the same report. The data suggests that the technical case for shared spectrum in rural settings is stronger than carrier lobbying implies, reinforcing Bubley's argument that the real barrier is commercial rather than physical.
