Speaking at Tesla’s annual shareholder meeting, CEO Elon Musk – also CEO of SpaceX – briefly segued to his spaceflight company’s ambitious Starlink program and discussed how he believes the satellite constellation can support no more than 3-5% of the global population.

On May 23rd, SpaceX successfully launched 60 “v0.9” Starlink satellites – weighing as much as 18.5 tons (~41,000 lb) – into LEO, a first step unmatched in ambition in the history of commercial satellites. Delivered to an orbit of ~450 km (280 mi), all but four of the 60 spacecraft have managed to successfully power up their electric ion thrusters and 55 have already raised their orbits to ~500 km (310 mi). For what is effectively a technology/partial-prototype demonstration mission, the record of Starlink v0.9 performance is extremely impressive and bodes well for a quick and relatively easy design optimization (to “v1.0”) before true mass production can begin.

In general, Musk was more than willing to acknowledge some of the potential limitations of a Low Earth Orbit (LEO) broadband satellite constellation at Tesla’s 2019 shareholder meeting. Most notably, he bluntly noted that Starlink is not designed to service densely populated areas and will predominately be focused on low to medium-density populaces. Triggered by an investor’s question about the possibility of integrating Starlink into future Tesla cars, Musk reiterated that SpaceX’s first-generation Starlink user terminals (i.e. ground antennas) will be roughly the size of a “medium pizza”.

Although pizza sizing is not exactly ISO-certified, Starlink’s user antennas will presumably be around 12-14 inches (30-36 cm) wide and come in a square form factor. Thanks to the use of what Musk believes are the most advanced phased array antennas in the world, neither the antennas on Starlink satellites or user terminals will need to physically move to maintain a strong signal. Still, as Musk notes, an antenna the size of medium pizza box would still stick out like a sore thumb on the typically all-glass roof of an of Tesla’s consumer cars, although built-in Starlink antennas might actually make sense on Tesla Semis.

Elon Musk’s specific comment indicated that Starlink – at least in its current iteration – was never meant to serve more than “3-5%” of Earth (population: ~7.8 billion), with most or all of its users nominally located in areas with low to medium population densities. This generally confirms technical suspicions that Starlink (and other constellations like OneWeb and Telesat) is not really capable of providing internet to everyone per se.

For SpaceX, each Starlink satellite – per official statements that the first 60 satellites represent more than 1 terabit of bandwidth – likely offers bandwidth of roughly 17-20 gigabits per second. In simpler terms, this means that one Starlink satellite overhead could theoretically support as many as 4000 users simultaneously streaming YouTube videos at 1080p/30fps, a figure that sounds impressive but glosses over the sheer number of people that live in cities. Importantly, every single Starlink satellite at ~550 km will likely have a service radius of several thousand – if not tens of thousands of – square kilometers.

Although each satellite is just a few square meters, they may be able to serve internet to thousands of people simultaneously. (SpaceX)

Even though the US is exceptionally large and spread out relative to most other countries, a single square kilometer of New York City, Los Angeles, San Francisco, Boston, Miami, Seattle, or dozens of other cities could effortlessly saturate a Starlink satellite’s bandwidth. Even the smallest of towns and cities could easily use most or all of ~20 Gbps at peak hours. In short, Starlink is going to be extremely bandwidth-constrained. Even if SpaceX can double or triple each satellite’s bandwidth and have 10-100 satellites overhead and capable of delivering internet at any given moment, it’s hard to imagine that Starlink will ever be able to serve every person that falls under its coverage area.

Additionally, this means that there is a strong chance that Starlink internet customers will be subject to relatively strict bandwidth limitations and throttling at peak hours. Thankfully, these limitations will be made entirely out of technical necessity, standing in stark contrast to the arbitrary, greed-motivated carriers and ISPs Americans are almost universally accustomed to. In an absolute worst-case scenario, Starlink’s already-connected US customers would get roughly the same quality of service they are used to at roughly the same price. However, they would be able to rest assured that their money was going to SpaceX instead of filling the pockets of the robber-baron-esque shareholders and executives that run American ISPs.

Ultimately, the estimates provided above are exceptionally conservative and generally assume worst-case scenarios. SpaceX could very well beat expectations and develop unique and innovative ways of efficiently using its available bandwidth, while also tirelessly working to improve its technology and expand the carrying capacity of newer satellites. In general, CEO Elon Musk’s comments serve as an excellent temper to the hype surrounding Starlink. SpaceX isn’t going to initially be breaking the backs of Comcast or Time Warner but there’s no reason to believe that that day will never come.

Verizon, AT&T and T-Mobile are trying to shut Starlink out before FCC vote

AT&T, Verizon and T-Mobile want 290 MHz cut from an FCC satellite plan before Thursday.

Starlink D2D direct to device vs Verizon, AT&T (Concept render by Grok)

AT&T, Verizon and T-Mobile are asking the Federal Communications Commission to pull nearly 300 MHz of spectrum out of a proposal that would let satellite companies like SpaceX offer cell service directly to ordinary phones. The request lands one day before the agency votes on it.

The FCC will vote Thursday, October 29, on a notice of proposed rulemaking that would make an additional 482 MHz available for direct to device service, expanding the number of eligible bands from five to 13, according to the FCC fact sheet. It would also scrap the rule requiring a satellite operator to lease spectrum from carriers, replacing it with a certification that the operator has coexistence agreements in place or holds the terrestrial license itself.

That second path matters for SpaceX. As Teslarati reported earlier this month, SpaceX agreed to buy Grain Management’s nationwide 800 MHz portfolio to turn Starlink Mobile into a full US carrier, adding to the spectrum it already bought from EchoStar.

The carriers want two bands removed, 2.5 GHz and 3.45 GHz, which make up 290 MHz of the 482 MHz on the table. Through industry group CTIA, they argued that about 300 million users depend on those bands and that satellite operations in them are not technically feasible. T-Mobile, which calls 2.5 GHz the foundation of its Ultra Capacity 5G network, said in its own filing that satellite interference could wipe out up to 96% of a cell site’s uplink coverage area and cut uplink speeds by 88% to 99%.

Executives from all three carriers met with FCC staff on October 20, and T-Mobile CEO Srini Gopalan met separately with FCC Chairman Brendan Carr. T-Mobile’s role stands out because it is still SpaceX’s US launch partner for Starlink Mobile. The three carriers have also teamed up on their own satellite joint venture to pool spectrum, a move widely seen as a response to Starlink.

SpaceX is asking for the opposite. In an October 23 filing after meetings with FCC staff and commissioners’ offices, the company asked regulators to add the 902 to 928 MHz band to the proposal. “Doing so now saves time later,” SpaceX wrote. The company also asked the FCC to modernize interference rules and align satellite deployment requirements with those for terrestrial cell networks, saying the goal is to let satellite and ground networks work together so Americans stay connected wherever they are.

The carriers have not been shy about how they view SpaceX as a competitor. On Verizon’s third quarter earnings call Monday, its chief executive said Starlink Mobile “just can’t compete with a terrestrial network” and estimated SpaceX would need four to six years and $300 billion to $500 billion to build a full US carrier network.

Thursday’s vote will not settle which bands survive. Adopting the notice opens a public comment period, with final rules to come later in the proceeding. The FCC already considered and rejected 2.5 GHz for satellite coverage once, in 2024. SpaceX also is not the only satellite player watching: the FCC approved Amazon’s $11.6 billion acquisition of Globalstar on October 27, giving its planned direct to device fleet its own mobile satellite spectrum.

Tesla Semi catches fire in California: what we know

Published

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.

The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.

There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.

However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.

The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.

The truck’s driver said that the Semi caught fire, but he did not have an explanation.

An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year.

Tesla’s ‘Emergency Drive Away’ function gets its first use in the real world

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.

A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.

“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.

Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.

Tesla constitutes the following situations as reasonable justifications for activating the feature:

  • You face an immediate threat to your life or personal safety.
  • You must leave the area immediately.
  • Exiting the vehicle is unsafe.
  • Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.

After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.
