According to the FCC's fifth "Measuring Broadband America" report, broadband speed offerings to the average consumer continue to increase at a rapid pace, and broadband service providers generally are delivering actual speeds that meet or exceed advertised speeds. However, results are not uniform across technologies, the FCC says. The report indicates a growing disparity in advertised download speeds between many DSL-based broadband services and most cable- and fiber-based broadband services.
"Today's report confirms that advances in network technology are yielding significant improvements in broadband speeds and quality," said FCC Chairman Tom Wheeler in a statement. "Faster, better broadband will unleash new innovations and new services to improve the lives of the American people. This comprehensive assessment of broadband performance helps to keep consumers informed and hold ISPs accountable."
Among the findings:
- Significant growth in advertised broadband speeds available to consumers, though the results are not uniform across technologies. Averaged across all participating ISPs, maximum advertised speeds increased from 37.2 Mbps in September 2013 to 72 Mbps in September 2014, an increase of 94%. Largely spurred by the deployment of enabling technologies such as DOCSIS 3.0, the maximum advertised download speeds offered by ISPs using cable systems increased from 12-20 Mbps in March 2011 to 50-105 Mbps in September 2014. However, maximum DSL speed offerings have not kept up with that growth. While average DSL consumer speeds have increased, maximum DSL speed offerings have stayed largely stagnant since 2011, with most DSL providers offering maximum downstream rates of 12 Mbps or less.
- Actual speeds experienced by most ISPs' subscribers are close to or exceed advertised speeds. All ISPs using cable, fiber or satellite technologies advertise speeds for services that on average are close to or below the actual speeds experienced by their subscribers. However, some DSL providers continue to advertise speeds that on average exceed actual speeds.
- Consumers with access to faster services continue to migrate to higher service tiers. Participating panelists who in September 2013 subscribed to service tiers with advertised speeds between 15 and 30 Mbps - offered mostly by cable and fiber services - migrated at high rates within the following year to a service tier with a higher advertised downstream speed. In contrast, among panelists subscribed in September 2013 to service tiers with advertised downstream speeds of less than 15 Mbps - offered mostly by DSL services - only a few percent migrated within the following year to a service tier with a higher download speed.
- Latency and packet loss vary by technologies. Consumers generally experienced low latency on DSL, cable and fiber systems. Higher latency in satellite services may affect the perceived quality of interactive applications such as VoIP calls, video chat and multiplayer games. Consumers generally experienced low packet loss on cable, satellite and fiber systems. Moderate packet loss experienced by a few DSL providers may affect the perceived quality of video chat, multiplayer games and video streaming.
