Researchers from Nokia and GFiber Labs (the experimental arm of Google Fiber) successfully achieved 41.89 Gbps download speeds on a live Google Fiber network. This marks the first time that Nokia’s 50G PON (passive optical network) technology has been used on a Google-owned network, and its one of the only examples of live 50 Gig networking in the United States.
You can collect a lot of data about someone, and then send them a lot of ads at 50Gbps.
