Carriers must offer broadband service with latency suitable for real-time applications, including voice over IP (VoIP) calling. 26)Ī latency test is a single measurement of latency, often performed using a single User Datagram Protocol (UDP) packet or a group of three Internet Control Message Protocol (ICMP) or UDP packets sent at essentially the same time. 24-26)Ī carrier may report that no test was successfully completed due to “crosstalk” caused by consumer activity if the consumer traffic meets thresholds of 64 Kbps for download tests or 32 Kbps for upload tests, and if the carrier begins attempting speed tests within the first 15 minutes of a testing hour and repeatedly retries and defers tests at one-minute intervals. Carriers must conduct at least one download test and one upload test during each testing hour at each testing location. Carriers serving areas greater than 500 air miles from an FCC-designated IXP may conduct all required speed and latency testing between the customer premises and the point at which traffic is aggregated for transport to the continental U.S.Ī speed test is a single measurement of download or upload speed of 10 to 15 seconds duration between a specific consumer location and specific remote server location that meets the FCC designated IXP requirements. More information about acceptable test paths and remote server locations is available here. Carriers that participate in multiple funds must meet the separate testing requirements of each of those funds.Ĭarriers must test speed and latency from the premises of active subscribers to a remote test server located at, or reached by passing through, an FCC-designated Internet exchange point (IXP), which is any building, facility or location housing a public Internet gateway that has an active interface to a qualifying Internet Autonomous System (ASN). Testing continues throughout a carrier’s support term. The windows to start testing vary by fund and began in 2020 with CAF Phase II Model carriers. Bringing Puerto Rico Together (Uniendo a Puerto Rico) and the Connect USVI Fund (PR/USVI).Connect America Fund Broadband Loop Support (CAF BLS).Alternative Connect America Cost Model II (ACAM II).Connect America Fund Phase II Auction (CAF II Auction).Revised Alternative Connect America Cost Model (Revised ACAM).Alternative Connect America Cost Model (Original ACAM).Connect America Fund Phase II Model (CAF II Model).Testing mandates apply to carriers participating in the following funds: The performance measures testing framework requires carriers to conduct one week of speed and latency testing using a random sample of CAF-supported broadband locations with active subscribers selected by USAC in each quarter of the calendar year. ![]() Carriers that fail to meet the performance measures standards required of their funds may face potential withholding of support. The FCC mandates that at least 80 percent of network speed measurements be at 80 percent of required speeds and 95 percent of latency measurements be at or below 100 milliseconds round-trip time. Established by FCC orders in 20, these requirements aim to maximize the impact of CAF investments to close the digital divide in rural America and ensure that people living in rural communities have access to the same high-quality networks as those living in urban areas. Under this new framework, carriers that receive CAF support to provide fixed-location broadband service must conduct speed and latency testing of their networks and submit the results to USAC as part of the annual compliance process. The FCC performance measures testing framework confirms that broadband service subsidized by the Connect America Fund (CAF) meets basic speed and latency performance standards.
