(Louis Abate)The city of Los Angeles last year started taking proposals for a plan to build out a gigabit fiber broadband network for every business and residence in the city. Only one company publicly shared their full proposal publicly, and it doesn’t exactly make the future of L.A. fiber look bright. Reporting on the proposal, Ars Technica calls the company’s claims “overly optimistic,” which looks like an understatement. The Dutch firm, Angie Communications, says they can run fiber through the entire city in five years for an initial cost of $2.5 billion.
