CARNEY — Carney-based UP Fiber said it will acquire AT&T’s wireline assets in the Upper Peninsula.

The move means Michigan Broadband Services will provide sales, marketing, billing and technical support to AT&T customers after the close of the transaction. The AT&T wireline assets represent more than 9,000 miles of copper, 1,500 miles of business fiber, and network infrastructure across 40 wire centers that collectively provide voice and internet service to more than 9,000 residential and business customers, according to a recent news release from the company.

Michigan Broadband now has more than 5,000 customers, including in Dickinson County, and is in the early stages of a $100 million capital investment in fiber optic upgrades, according to the company, a subsidiary of MachTen Inc. with offices in Carney and Traverse City.

“This is an exciting opportunity to accelerate the development of broadband communications for the people who live and work in the Upper Peninsula,” Dan Miller, UP Fiber CEO, said in the news release. “We have an ambitious plan to invest in AT&T’s legacy copper network across the Upper Peninsula, build state-of-the-art fiber-optics, and upgrade customers to higher speed services that better meet their connectivity needs.”

“We are thrilled to be partnering with UP Fiber to bring our complete bundle of high-speed data, voice, streaming video and related services to the homes and businesses currently served by AT&T,” said Phil Truran, president of Michigan Broadband. “Our commitment to customer service, supported by a dedicated and local team, has been long recognized for its excellence.”

“We’ll work closely with our customers with wireline services in the region to provide a seamless transition to UP Fiber,” said Brian West, vice president and general manager-Greater Lakes AT&T.

UP Fiber and Michigan Broadband will collectively explore strategic opportunities to become the largest and most reliable broadband communications provider in the Upper Peninsula, with new product offerings and pricing tiers to be announced in the coming months, the news release states.
