Will SpaceX's Starlink LEO Satellites Succeed in Connecting the Unconnected?


While there are many initiatives going on to bring connectivity to rural, remote and other areas with little or no connectivity, none of them are as bold and advances as SpaceX's Starlink satellites.

According to SpaceNews last month:

SpaceX has asked the International Telecommunication Union to arrange spectrum for 30,000 additional Starlink satellites. 

SpaceX, which is already planning the world’s largest low-Earth-orbit broadband constellation by far, filed paperwork in recent weeks for up to 30,000 additional Starlink satellites on top of the 12,000 already approved by the U.S. Federal Communications Commission.

The FCC, on SpaceX’s behalf, submitted 20 filings to the ITU for 1,500 satellites apiece in various low Earth orbits, an ITU official confirmed Oct. 15 to SpaceNews. 

SpaceX deployed its first 60 Starlink satellites in May and plans to launch hundreds — potentially over a thousand — more in the year ahead. 

The ITU, a United Nations entity, coordinates spectrum at the international level for satellite operators to prevent signal interference and spectrum hogging. National regulators submit filing on behalf of their country’s satellite operators.

SpaceX’s ITU filings contain details about frequency usage, proposed orbital altitudes, and the number of satellites it desires. The filings do not say when SpaceX hopes to launch the satellites, or other details such as spacecraft throughput and deorbit timelines. 

ITU filings are an early step in deploying a satellite system, and are often made years before a company plans to build launch spacecraft. SpaceX will be required to disclose more details about its constellation when applying with the FCC for access to the U.S. market to offer broadband services, like it did with the 12,000-satellite constellation it began launching in May. 

In its filings, SpaceX said the additional 30,000 satellites would operate in low Earth orbit at altitudes ranging from 328 kilometers to 580 kilometers. 

SpaceX said the satellites will have steerable spot beams to link with customers, and “omnidirectional” beams for spacecraft telemetry, tracking and control functions. 

Filings trigger a seven-year deadline whereby the satellite operator, in this case SpaceX, must launch at least one satellite with its requested frequencies and operate it for 90 days. Once spectrum rights have been assigned through this “bring into use” procedure, other ventures must design their systems to avoid interference with the newly minted incumbent operator. 

The ITU is expected to change its “bring into use” rules during the upcoming World Radiocommunication Conference, which takes place from Oct. 28 to Nov. 22 in Sharm el-Sheikh, Egypt. Regulators intend to set more stringent rules for megaconstellation ventures, requiring them to launch percentages of their total constellation by to-be-determined deadlines in order to keep their priority spectrum rights.

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 ...

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. ...

Tutorial Session on Current Trends and Key Challenges of Satellite communications

The 2024 Global Forum on Connecting the World from the Skies , held on November 25-26, brought together policymakers, industry leaders, and technical experts to discuss the evolving landscape of Non-Terrestrial Networks (NTNs). Hosted by the International Telecommunication Union (ITU) and Saudi Arabia’s Communications, Space & Technology Commission (CST), the event highlighted NTNs' critical role in shaping the future of global connectivity. The conference featured a rich lineup of keynote speeches, panel discussions, tutorial sessions, and an award ceremony. One standout session on Day 1 was the tutorial "Satellite Communications: Current Trends and Key Challenges," delivered by Professor Riccardo De Gaudenzi of the University of Parma. This session explored the vital role satellite networks play in global communication, from video broadcasting to bridging connectivity gaps in underserved regions. Traditionally focused on broadcasting and professional applications, s...
