THE VIDEO SHELF · starlink network latency

Using ground relays with Starlink

Mark Handley of UCL explains, with simulation visualizations, how early Starlink satellites without inter-satellite links could still give low-latency wide-area communication by hopping via ground relays. He shows it can beat fibre on many long paths.

  • You don't need inter-satellite links for low latency, as Mark Handley has elegantly pointed out in his incredible video. I don't think internet access will amount to even 50% of the revenue of Starlink. [VIDEO]

  • I would highly recommend the video linked from this article: [VIDEO] It's a simulation of the various ways in which the Starlink network could be arranged to route between satellites and ground stations; very detailed and super interesting.
