In the six years since it was launched, Google Fiber has only expanded to three metropolitan areas, and even though it’s working on expanding to another six, that’s still an unbearably slow pace. You shouldn’t be upset with Google, however, because it takes a ridiculous amount of resources to build or buy the infrastructure required to provide internet service to people. That’s why the company is currently experimenting with a number of wireless technologies that it hopes will allow it to beam internet access to people’s homes, rather than delivering it to them through physical cables that require tons of money to place and maintain.
