OneWeb says a check of its low-Earth orbit satellites has delivered broadband speeds of greater than 400Mbps with moderate latency of 32ms.
“The checks, which happened in Seoul, South Korea, constitute probably the most vital demonstration of the OneWeb constellation thus far, proving its talent to offer awesome broadband connectivity any place on this planet,” OneWeb stated in an announcement the day before today.
The corporate stated it is heading in the right direction towards developing “a completely functioning international constellation in 2021 and handing over partial carrier starting as early as 2020.” The check described the day before today concerned six OneWeb satellites that had been introduced in February. OneWeb says its industrial community “will get started with an preliminary 650 satellites and develop as much as 1,980 satellites.”
Whilst the 32ms latency determine is a mean, the 400Mbps end result appears to be the height pace delivered all through the check. OneWeb stated its check additionally demonstrated “seamless beam and satellite tv for pc handovers; correct antenna pointing and monitoring; [and] live-streamed video at resolutions as much as 1080p.”
SpaceX and Amazon carrier within the works
OneWeb is one in every of a number of firms aiming to offer international broadband connectivity with a community of low-Earth satellites. Present satellite tv for pc programs are hampered through median latency of just about 600ms, making them an fallacious substitute for cable or fiber programs. However the decrease orbits utilized by OneWeb and different firms must lead to latencies which can be a lot nearer to wireline high quality.
Federal Communications Fee checking out discovered that fiber ISPs ship median latencies of 12ms to 20ms whilst cable ISPs ship median latencies of 15ms to 34ms. DSL suppliers had been measured at 25ms to 80ms. (See web page 477 of this FCC report for latencies through ISP.)
OneWeb’s largest competitor thus far is SpaceX, which has FCC permission to release nearly 12,000 low-Earth satellites. OneWeb received its initial FCC approval in June 2017, whilst SpaceX were given its first primary FCC approval in March 2018 and introduced 60 satellites in May 2019. SpaceX lost contact with 3 of the 60 satellites.
Extra just lately, Amazon printed plans for the same broadband-satellite carrier, and the corporate implemented for FCC authorization earlier this month.
