PORTLAND — AT&T recently announced that it has invested more than $70 million in its wireless and wired networks in Maine between 2011-13, driving a wide range of upgrades to enhance speed, reliability, coverage and performance for residents and business customers.

Advancing its Project Velocity IP (VIP), an investment plan to expand and enhance its wireless and wired IP broadband networks, AT&T in 2013 made nearly 50 network upgrades in Maine, including new cell sites, addition of wireless and wired network capacity, and new broadband network connections.

Notable Maine network enhancements in 2013 included launching AT&T’s 4G LTE network in Lewiston-Auburn and activating a new 4G mobile Internet cell site in Waterford.

“To expand economic opportunity in Maine, especially if our rural communities are to compete, 21st century technologies must be widely accessible,” said Gov. Paul R. LePage. “We must keep working together and support ongoing efforts to extend Internet connectivity to every business, home and community. This investment in fast and reliable service not only helps to level the playing field for small and mid-sized businesses across the state, but also enhances quality of life for Mainers.”
