Vermont Tested Mobile Networks Amid Rural Coverage Gaps
State inspectors drove thousands of miles to quantify persistent connectivity challenges in remote mountainous areas.

The Vermont Department of Public Service has conducted extensive driving tests to measure real-world cellular coverage. These efforts revealed that while 77% of test locations showed increased data speeds in 2024, significant service gaps persist across the state.
Why it matters
Vermont's rugged topography of mountainous peaks and narrow valleys often renders provider propagation models inaccurate at a granular level. The ongoing testing aims to address public safety risks caused by inconsistent signal strength in areas like Lamoille County.
Department staff drove 6,000 to 7,000 miles of road using a bank of mobile devices to measure actual signal strength. While tests showed a 36% improvement in passing results compared to 2022, granular coverage remains challenged by physical geography.
The players
Vermont Department of Public Service
The state agency responsible for overseeing energy and telecommunications policy and monitoring statewide network infrastructure.
AT&T
The national telecommunications provider that operates the FirstNet public safety network under a 25-year federal contract.
Vermont Public Utility Commission
The regulatory body that manages the administrative process for permitting new cellular towers across the state.
The details
Staff use a bank of mobile cellphones to gather empirical performance metrics across state roadways, bypassing provider-submitted coverage maps that often overestimate reliability. The division also maintains an amenable landlord list to help service providers identify viable sites for infrastructure like the cellular towers recently debated in Hyde Park. FirstNet, a national network operated by AT&T under a 25-year federal contract, is currently deploying small cellphone repeaters in Elmore to mitigate emergency communication risks.

2024: Completion of the most recent data collection iteration.
2029: Next scheduled update for the 10-Year Telecommunications Plan.
The Tech Race
Vermont's granular testing marks a departure from reliance on theoretical propagation models that currently define the industry's approach to rural coverage. The data establishes a baseline for the state's 10-Year Telecommunications Plan as it navigates the persistent physical constraints of mountainous topography.
Residents in areas like Lamoille County currently face 10 to 20-minute travel delays to report emergency accidents due to poor service. While state-assisted infrastructure projects are underway, reliable connectivity remains dependent on local tower permitting and site availability.
The takeaway
The state is prioritizing empirical testing to force more accurate coverage reporting by major providers. Residents should monitor public utility hearings in their local towns for updates on pending tower applications.
