Alphabet CEO Larry Page is not happy with the speed of Google Fiber's rollout and last month told the unit's chief Craig Barratt to halve the unit's headcount to 500 and cut costs, sources told The Information.
But digging up streets and dealing with local municipalities to lay fiber is expensive in urban areas and out of the question for remote regions. According to Recode, it cost $1bn to lay fiber in Kansas. Yet for all the costs sunk into Google Fiber, the service only had around 200,000 subscribers by the end of 2014, according to The Information, a figure that is well short of the five million hoped for within five years.
The planned layoffs follow a number of signs that Alphabet may be winding back its Fiber ambitions and switching focus to wireless technologies. Its execs have previously expressed interest in fixed wireless technologies to address rural markets.
In June it also acquired WebPass, a small ISP that delivers high-speed wireless broadband to residential buildings and businesses. The technology it acquired could help Google expand its services in metropolitan areas.
Following the creation of Alphabet last year, Fiber was carved out of Google and made a key part of Alphabet's Other Bets group, which was formed to give investors a clearer picture of how much these risky projects cost. Other projects in this group include X, the organisation behind Project Loon and Google's autonomous vehicles, Nest, and GV. Other Bets made a $1.6bn loss in the first half of 2016, roughly in line with its $3.6bn loss in 2015.
Alphabet may also be looking to Project Loon for profitability, with the company recently hiring Tom Moore, co-founder of satellite broadband service WildBlue Communications. Bloombergreported this week that Moore starts as vice president of X and will become general manager of Project Loon in mid-September.
Astro Teller, the head of X, said that Moore will help it launch into the "commercial stage", following a number of trials in partnership with local mobile carriers, such as Vodafone in New Zealand and Telstra in Australia.
