![]() ![]() Other experts said they're not surprised by the study's findings that carriers are throttling content. And we don't throttle, discriminate or degrade network performance based on content," AT&T spokesman Jim Greer told CBS MoneyWatch.ĬTIA, the trade association representing wireless communications companies, said in a blog post last year that the Wehe app, which runs speed tests between mobile devices and its own servers using simulated data traffic, doesn't "account for basic wireless network engineering, consumer preference and how mobile content is distributed over the internet." Post-net neutrality world? AT&T: "We don't throttle"ĪT&T disputed the study's methodology, attributing the differences in streaming speeds to consumers' individual network plans and settings and denying that the carrier is deliberately slowing select internet content. It could be that Amazon is paying for that privilege," Toyama told CBS MoneyWatch. "That is the kind of back-end deal companies are cutting now because of the lifting of net neutrality. "Bandwidth isn't free, and I think most of the time these companies are trying to provide customers with an experience they would be reasonably happy with, and occasionally they have to make trade offs," said Kentaro Toyama, a professor of community information at the University of Michigan.īut what he called the "discrepancy" in speeds between content from certain companies is hard to explain, he said. T-Mobile throttled Amazon Prime video in 51% of the tests, Netflix in 61% and YouTube in 67% of the tests. The analysis found that, over a 12-month period ending in early 2019, AT&T slowed the speed of Netflix programming 70% of time and YouTube content 74% of the time, while never throttling Amazon's Prime video-streaming service. Yet a number of carriers - including AT&T, Sprint, T-Mobile and Verizon - are throttling content even at off-peak times, according to a study from Northeastern University and the University of Massachusetts Amherst. The practice, known as "throttling," refers to internet service providers' intentional slowing of internet speeds to reduce bandwidth congestion during peak hours. The findings could fuel concerns about the Federal Communications Commission's move in 2017 to strike down "net neutrality" rules, a move critics warned could allow broadband providers to offer faster transmission speeds for preferred content providers. wireless carriers are deliberately slowing the speed at which some video content is streamed on the internet, researchers contend. Experts say that the FCC's 2017 repeal of net neutrality rules enables broadband companies to play favorites with content providers.AT&T throttled YouTube and Netflix content, but not Amazon Prime video, they found in a recent study.Researchers say that wireless carriers "throttle" streaming video content around the clock - not just during times of peak congestion. ![]()
