BANGOR, Maine — Redzone Wireless announced Tuesday a pair of major developments aimed at wooing customers dissatisfied with their current internet service providers.

The Rockland-based broadband provider held an event in Bangor’s Tarratine Club to announce the latest target of its burgeoning expansion efforts — Greater Bangor. Redzone switched on a series of five 4G LTE wireless broadband transmission sites in the area, which will allow the company to serve customers in Bangor, Brewer, Hermon, Hampden, Glenburn, Levant, Carmel, Newburgh and Orrington.

“This growth initiative represents our most ambitious network development project to date and pushes our technical capabilities to an entirely new level,” said James McKenna, the company’s president.

The expansion means more than 150,000 Maine homes and businesses will have the option of picking Redzone as an internet service provider. To this point, the company’s primary service areas have been in Portland and along the coast.

In addition to expanding to Bangor, the company announced Tuesday plans to launch a new program to allow more rural areas of the state to offer wireless LTE internet to homes and businesses.

The program is called “Fast for 5.” Redzone says it will fully cover the costs of designing, building and managing a Redzone Wireless network in municipalities interested in bringing high-speed wireless broadband. In exchange, the communities must commit to ensuring a certain number of residents use Redzone broadband for a five-year term.

The idea is to bring broadband service to communities that have struggled to find a way to make the investment in the past. For Redzone, it means more potential customers. Redzone plans to commit $1 million to launch that effort in 2017.

Redzone has been open about the fact that it’s hoping to court customers who aren’t satisfied with their existing internet service and are looking for a change.

“The ultimate goal is for businesses and citizens in Maine to have access to high-speed broadband wherever they may be,” said Dick Thompson, interim chairman of the ConnectME Authority. “Engaging and supporting municipalities is a sound investment that will further serve our rural population.”

Tuesday’s event was primarily attended by community and economic development officials from the area.

McKenna said Maine frequently ranks among the worst states in the nation in terms of broadband availability, which can have a negative impact on efforts to attract business to the state. Redzone plans to expand rapidly by ensuring 90 percent of the state’s households have the option of using Redzone by 2018. Currently, about 25 percent of Mainers have it as an option, but that’s up from about 6 percent this time last year, according to the company.

“The variable of broadband is hugely significant,” McKenna said. “If you don’t address that piece, the businesses just can’t come.”

The company’s residential plan starts at $39 per month for service that delivers up to 10 million bits per second. It offers faster services, including business plans starting at $89 per month for up to 50 Mbps. The best “ultra fast” business plan they have available is up to 200 Mbps for $159 per month.

McKenna said that as the company expands, it will be able to do so at a lesser cost than other companies that rely on fiber-optic connections. He declined to go into detail on what effect the investments and expansions might have on Redzone’s rates, but did say “we’re trying to keep rates as low as possible. Mainers purchase with their wallets.”
