Alphabet is shifting the focus of its high-speed internet plans to wireless technology as the initial plans cost more than the company initially thought.

The company’s internet provider, Google Fiber, offers broadband Internet and cable television to a small and slowly increasing number of locations in the US.

According to The Wall Street Journal, the company plans to set up wireless transmitters across major cities and use them to provide residential internet.

Los Angeles, Chicago, and Dallas are reportedly on its list, with plans to reach a dozen new metro areas in total.

Google said: “We're continuing to work with city leaders to explore the possibility of bringing Google Fiber to many cities.

“This means deploying the latest technologies in alignment with our product road map, while understanding local considerations and challenges, which takes time.” 

The company seeks to lease existing fiber or ask cities or power firms to build the networks rather than building its own. The move will help Google lower costs and speed up its expansion.

When Google Fiber was first unveiled in 2010, smaller cities across the US showed interest to work with the company.

In 2012, the super-fast broadband service was launched in Kansas Cty, which claiming to offer users with speeds of about 1Gbps (gigabit per second).

The service was then expanded to Austin, Texas and Provo, Utah in April 2013, with expansions in 2014 and 2015 to Atlanta, Charlotte, Raleigh–Durham, Nashville, Salt Lake City, and San Antonio.
