<div dir="auto">All valid thoughts - my simulation using the currently known gateways shows that coverage is from good to acceptable over all of Ukraine, see below:<br />

Starlink is not suitable for serving 40 million Ukranians, just the same as it is not suitable to serve the entire population of Montana. You see those messages because Montana cells, where they have allocated capacity, are full already, and won’t allow more terminals until there is more capacity in the constellation.<br />
<br />
The Starlink terminals would best be use in a tactical approach, i.e. not for fixed service on a rooftop. You can also implement OPSEC such as placing the UT 300 meters away over ethernet, thus not exposing your location as much to RF-targeted missile attacks.<br />
<br />
In terms of jamming, it can all be jammed - in any case, you’d need to overwhelm several satellites, many not inside the theater, and which are constantly moving. You could jam the downlink using an aerial platform, and this capability exists.</div>

<p>Hm. So what would we expect here?</p>
<p>- Service provided from Wola Krobowska in Poland and Kaunas in Lithuania (if it's operational yet), and in the coming days or weeks perhaps from other sites in eastern and southeastern Europe (Romania looks like a good spot for that).<br />
- Ukraine stretches from about 52 degrees north to around 46 degrees north (or 44-something deg if you include Crimea, which however might have some problems getting dishys right now). That's prime Starlink latitude.<br /></p>
<p>But:<br /></p>
<p>- Ukraine also stretches about 1300 km across, and some of its parts are almost 1500 km away from the known gateways. That's a lot by Starlink standards (remember, Tonga gets "spotty" service at 750 km from the gateway in Fiji).<br />
- If Starlink became a significant player in Ukraine, I would expect Russia to want to jam them. How difficult is it to jam Starlink satellites on the uplink from Belarus and Russia itself? Probably not too difficult. Similarly, the downlinks could potentially be jammed from the air.<br />
- Where are Ukrainians going to put the dishys so they're not seen by Russian helicopter patrols? Would you put one on you roof if you were Ukrainian? Will they come in camouflage colours?<br />
- Ukraine has a pretty long border with the EU/NATO, so plenty of opportunity to throw a bit of fibre over the fence and re-establish connectivity. Similarly, it's had a reasonably mature telecoms and Internet market and a lot of technically savy people ... I'd say Russia would have a hard time shutting the Internet out of Ukraine completely in a hurry.<br />
- Last but not least: If I look at, e.g., Montana, which is a similar latitude and has a population of just over a million, and try to order Starlink there (Kalispell, for example), I get the message: "Order now to reserve your Starlink. Starlink is currently at capacity in your area, so your order may not be fulfilled until 2023 or later. You will receive a notification once your Starlink is ready to ship." That's with three gateways in easy range, two of them in under 200 km distance. Now if they can't even service Montana, how would they provide service to 40 million Ukrainians?<br /></p>

<p class="">I like that mental model, too, although the way Internet development has historically played out in the Pacific has been quite diverse in comparison.</p>
<p class="">Some place, e.g., Niue, did initially exactly that - the local geek guru got it going and things went from there. Other places were worried that their monopoly telco might get competition, and kept a lid on it for reasons political or simply because they genuinely felt that their island was too small not to pool resources in a single provider. Some islands don't have geek gurus. Tonga is a case in point here - the smaller islands that didn't have cable so far are, with the exception of 'Eua, very small in terms of population, a few hundred people at most, many only have a few dozen.<br class="" /></p>
<p class="">On many of these smaller islands, the only businesses are small stall-like shops that will sell bread from the local baker and necessities such as tooth paste, soap, batteries and that sort of thing, plus peanuts and other imported snacks. Whatever the supply ship brings when it comes, which could be once every few months in some cases. Most people live off the land, go fishing or collect shellfish on the reef, and in some cases will produce crafts like pandanus mats or tapa cloth, some of which is sent overseas and can generate a bit of income. There are a lot of old people in comparison to younger folk, who have often left for a life overseas to support those back home. Post offices, coffee shops and libraries exist only on the larger islands. The smaller islands will always have more churches than you can count, and sadly some of these still see the Internet as something to be kept out at all cost - something that's by no means unique to Tonga.<br class="" /></p>

so far. A local geek guru would get one for the local library/coffee<br class="" />
shop/post office, set up local wifi and computers cybercafe style, set<br class="" />
up a few other p2p wireless links, perhaps a lte node, etc, and<br class="" />
enhance village to village (or island to island) communications via a<br class="" />
starlink node X miles away, as well as provide/integrate with more<br class="" />
local services such as local email, videoconferencing and telephony<br class="" />
without having to traverse the sat at all.<br class="" />
<br class="" />
As things built out, fiber or other forms of connectivity would<br class="" />
emerge, eventually connecting via land or high speed p2p fixed<br class="" />
wireless links, and starlink reverting to more of a backup. Existing<br class="" />
ISPs (notably wisps), would build out excessively remote areas this<br class="" />
way.<br class="" />
<br class="" />
This "vision" is highly influenced by efforts such as the villagetelco<br class="" />
and olpc. To some extent the new "premium" service could go that way,<br class="" />
but classic business networking services like BGP, working ipv6, real<br class="" />
ipv4 addresses, etc, are so far, lacking. BYOIP and dual homing for<br class="" />
existing providers has not been spoken of...<br class="" />
<br class="" />
But anyway, I hope the government of tonga uses what they got wisely,<br class="" />
though my primary use case would be for multiplexing low bitrate apps<br class="" />
for a lot of people (like voip and financial transactions), over the<br class="" />
web for a few.<br class="" />

>>> Tongans are also an incredibly patient and grateful people, whatever they have they make do with. I first had plenty of opportunity to witness this when we went there on our honeymoon in 2003. One of the island villages we stayed on in the Ha'apai group had piped water to the beachfront properties installed yonks ago, before they got electricity. Then the Australians brought electricity around 2002 & used a trench digger to put the cable in along the main drag, unaware that there were water pipes in the ground. The locals were too grateful for the electricity to complain that they now needed to walk to the cistern to get their water, and the problem remained unsolved a year later - we had to wash from big barrels and a bit of rainwater off the roof. As we left Ha'apai after a hair-raising boat passage in a 4 m boat in 6 m swells, we didn't have a flight booked, so went to the Ha'apai office of the long since defunct Royal Tongan Airlines to book ourselves on the next flight out. The two ladies in the office gave us their most welcoming smiles, along with the regret that they couldn't book us a ticket as the computer were down. We asked how long such outages typically lasted and were told that they didn't know but this one had lasted three months already. We then made our way to the airport with the help of a few bored Mormon missionaries. We were the only people there until the station manager turned up. He reckoned there would be seats and told us that he was the local baker as well and had been trying out artisan bread recipes, which the locals liked, but was finding it difficult to get the right flour. Nice chat! Eventually the plane arrived early without any passengers. Pilots and station manager spent ten seconds bitching about their employer (rightfully so, a long story I shan't repeat - but neither the employees' nor the management's fault, though), then the pilots decided that they wanted lunch in Vava'u and off we took 15 minutes ahead of schedule...<br class="" />
