Gov. Ned Lamont announced Monday the expansion of high-speed internet access along the Metro-North New Haven line thanks to a partnership with AT&T.

Politicians say that the No. 1 commuter complaint has been spotty service on their train rides. In the next year and a half, that will change.

Right now, 5G capabilities are already available on the New Haven line from Greenwich to Bridgeport. Officials are working to expand high-speed mobile internet from New Haven to the state line.

Commuters will have a dedicated signal that will work even through tunnels. This multimillion-dollar project is not using any taxpayer dollars -- it's all funded by AT&T.

Lamont says the 5G capabilities on the trains is a great economic driver for the state.

"This is a way that you bring Connecticut's economy back to life. Speeding up the transportation, speeding up the internet access, being able to do everything from a rail car that you can do from your office," said Lamont.

A handful of protesters tried to derail the announcement by saying the radio frequency is dangerous. AT&T says it adheres to all the FCC exposure guidelines.
