4G is a hot topic here on BGR and as such, we’ve likely become more numb than we should when it comes to advertised data speeds. We’re so used to seeing “theoretical limits” that are so far from reality we just chuckle and move along. The wireline broadband industry, however, is a different beast. According to a study recently conducted by the Federal Communications Commission, major broadband Internet service provides in the U.S. deliver data speeds that are generally between 80% and 90% of the speeds they advertise. The Associated Press reports that the FCC’s study measured data speeds delivered to thousands of U.S. broadband subscribers this past March from 13 of the nation’s top ISPs including Time Warner, Comcast, AT&T and Verizon. The three most popular wired broadband technologies were covered by the study — DSL, cable and fiber — and data rates were said to have been close to the advertised speeds during both peak and off-peak times. The AP notes that the FCC’s study didn’t delve into speeds delivered by wireless data services, which is a study we would love to see.
