Measuring Broadband America February 2013 A Report on Consumer Wireline Broadband Performance in the U.S. (Full Report and Technical Appendix)
暫譯: 測量美國寬頻 2013年2月 消費者有線寬頻性能報告（完整報告及技術附錄）

This 2013 Measuring Broadband America—February Report contains the most recent results from the Federal Communication Commission’s (FCC) Measuring Broadband America program. This program, whose first results were published in August 2011, is an ongoing, rigorous, nationwide study of residential broadband performance in the United States. This study, like those conducted before, involves actual performance tests for thousands of subscribers of Internet Service Providers (ISPs) serving well over 80 percent of the residential market. Our initial Measuring Broadband America Report presented the first broad-scale study of actual consumer broadband performance throughout the United States. This effort was followed approximately a year later by a second report, released in July 2012, and now the present report. As explained in the included Technical Appendix, each report in this series is based on measurements taken during a single reference month that has been chosen to represent a typical usage period for the average consumer. The reference month for the first report was March 2011, and the collection period for the second report, initially set for March 2011, was shifted to April 2012 to ensure collection of a sufficient amount of valid data. The reference month for this report is September 2012, five months after the previous testing period. As such, we present this as a supplemental report, noting that substantive network change is best measured in years, not months. Going forward, we plan to repeat testing each year in the month of September, and transition to annual reporting. In this report, we are pleased to include results on satellite technology for the first time, based on test results collected from ViaSat, a major satellite services provider.1 While in the past we have collected and released raw data on satellite performance, we have not reported on test results from this technology, as we recognized that the industry was on the verge of a major transition. In 2011, the satellite industry began launching a new generation of satellites offering performance as much as 100 times2 superior to the previous generation, leading to the entry of new satellite-based broadband providers. Consequently, we are now able to include comparisons between satellite and wireline technologies in this report.
