Google Fiber Speed: By the numbers. The average Internet speed in the U.S. is 7.4 megabits per second (Mbps), according to a âState of the Internet Reportâ released by Akamai Technologies. It seems that the U.S. has some catching up to do in this department.
In its report, via Quartz, OpenSignal found that Starbucks, which recently began using in-store WiFi powered by Google, offered WiFi download speeds as fast as 9.01 Mbps (megabits per second). Thatâs faster than the average Americanâs 4G LTE connection, found on their phones, which topped out at 6.52 Mbps. To put that in perspective, Netflix requires you to have a 0.5 Mbps connection speed to even use its service. To stream a standard-definition movie, youâll need a connection with an average speed of 3 Mbps.
