Amazon's Project Kuiper Megaconstellation Aims to Deliver Fast, Affordable Broadband

Amazon's Project Kuiper is an initiative to increase global broadband access through a constellation of 3,236 satellites in low earth orbit (LEO). Their mission is to deliver fast, affordable broadband to unserved and underserved communities around the world.

A post on Amazon explains:

Project Kuiper started off as an internal code name for the program—and it stuck. The name refers to the Kuiper Belt, a region of the solar system that exists beyond the eight major planets. The Kuiper Belt itself is named after the late Dutch astronomer Gerard Kuiper, who is considered by many to be the father of modern planetary science.

Project Kuiper is a long-term initiative. Our FCC license requires that we deploy and operate at least half of our satellite constellation by July 2026. We’re preparing to launch our first two prototype satellites in early 2023, and we expect to provide service to the earliest Project Kuiper customers by the end of 2024.

This marketing video is a good explainer of Project Kuiper:

Recently Amazon shared a post about Project Kuiper’s low-cost customer terminals.

To use the service, customers will install an outdoor antenna—called a customer terminal—to communicate with satellites passing overhead. Traditionally, this equipment has been too large, too complex, and too expensive for many customers, making it difficult for LEO constellations to bridge the digital divide in a meaningful way. 

Project Kuiper plans to serve tens of millions of customers, so we set an ambitious goal at the start of the project: design a customer terminal that costs less than $500 to build. Project Kuiper engineers hit that milestone in 2020, inventing a new antenna architecture that was smaller and lighter than traditional designs. Since then, the team has continued to innovate to make its terminal designs even smaller, more affordable, and more capable.

Amazon recently unveiled the results of that work.

Our ultra-compact model provides speeds of up to 100 megabits per second (Mbps), our standard model delivers up to 400 Mbps, and our largest model, which is intended for enterprise, government, and telecommunications applications, delivers up to 1 gigabit per second (Gbps).

You can read more about terminals here. Let's hope the prototypes are launched successfully and deliver on the promises. This will increase the likelihood of the success of this project. We are certainly looking forward to it.

Laser Inter-Satellite Links (LISLs) in a Starlink Constellation

When we first talked about Starlink back in 2019 , we saw in the video that the concept involved laser communication to communicate between the satellites. While the initially launched satellites did not have the laser communication mechanism built in, it looks like they are being added to the newer ones.  A report from Fast Company in late 2021 said: One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with lasers, that encode data as pulses of light, can be much like that of deploying fiber-optic cable for terrestrial broadband: much faster speeds and much lower latency. “Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber,” SpaceX founder Elon Musk tweeted in July about the upgrade now beginning for that firm’s Starlink satellite constellation.

IEEE 802.11bn Ultra High Reliability (UHR), a.k.a. Wi-Fi 8

Back in 2020 we looked at the introductory post of Wi-Fi 7 which was followed up by a more detailed post in Feb 2022. We are now following on with an introductory post on the next generation Wi-Fi.  A new paper on arXiv explores the journey towards IEEE 802.11bn Ultra High Reliability (UHR), the amendment that will form the basis of Wi-Fi 8. Quoting selected items from the paper  below: After providing an overview of the nearly completed Wi-Fi 7 standard, we present new use cases calling for further Wi-Fi evolution. We also outline current standardization, certification, and spectrum allocation activities, sharing updates from the newly formed UHR Study Group. We then introduce the disruptive new features envisioned for Wi-Fi 8 and discuss the associated research challenges. Among those, we focus on access point coordination and demonstrate that it could build upon 802.11be multi-link operation to make Ultra High Reliability a reality in Wi-Fi 8. The IEEE 802.11bn UHR: Whose Study Gro

CSI-RS vs SRS Beamforming

In an issue of Signals Flash by Signals Research Group (SRG), they talked about 2 different types of MIMO. Quoting from their journal, "CSI-RS versus SRS. Those operators that have tested or made token use of MU-MIMO leverage a flavor of MU-MIMO that is based on CSI-RS. The MU-MIMO network we tested was based on SRS, which makes it far more likely to observe sixteen spatial layers (versus eight)." I reached out to Emil Björnson, Visiting Professor at KTH Royal Institute of Technology and Associate Professor at Linköping University to see if he has explained this in any of his videos. Here is what he said: " I'm not talking about 3GPP terminology in any of my videos. But you can listen to the slides that starts around 12:40 in this video (embedded below) . If you are looking for CSI-RS vs SRS based MU-MIMO, then jump to around 12:40 in this video where you can see CSI-RS being referred to as "grid of beams" and SRS is similar to the other option, which is t
