SpaceX says its satellite Internet service Starlink has achieved a latency of less than 20 milliseconds, which is on par with terrestrial broadband.

SpaceX included the data in a presentation sent to the FCC last Friday that was spotted by Reddit users. Two benchmark tests conducted using Ookla’s Speedtest.net service show that Starlink achieves download speeds of 102 to 103Mbps, upload speeds of 40 to 42Mbps, and latency of 18 to 19ms. (Note: Ookla is owned by Ziff Davis, the parent company of PCMag.com.)

The presentation was attached to a letter from SpaceX̵

7;s director of satellite policy, David Goldman, stating that the initial beta tests for Starlink were below 30ms in latency. (By comparison, the average latency for a fixed broadband connection in the United States is 25ms, while the speed of mobile networks is 48ms, according to Speedtest.net.)

SpaceX filed the request a day after the company publicly boasted that Starlink was already achieving a download speed higher than 100Mbps. The benchmarks provided to the FCC show that the company is not exaggerating.

Interestingly, both benchmarks occurred on June 30 in Seattle, Washington, at a time when SpaceX had only about 500 Starlink satellites in orbit. The company now has more than 700 satellites worldwide, which is likely to improve coverage and data rates.

According to the presentation, SpaceX produces about 120 Starlink satellites each month. The goal is to launch thousands of them into space to provide worldwide coverage and download speeds of 1Gbps.

The company is also on track to build thousands of consumer terminals that consumers can connect to their homes to get satellite broadband. In addition, SpaceX plans to prepare for a public beta test for users “in many US states.”

SpaceX has made the submission so that it can change the position of its original constellation of Starlink satellites, which is currently in orbit around the planet at 550 kilometers, “to accelerate the deployment to the polar regions, including Alaska,” the company said in a presentation.

The public beta version of SpaceX is expected to take place in the coming weeks. The company aims to formally launch before the end of the year for consumers based in the northern United States and lower Canada. Global distribution is planned for 2021.
