One of the reasons 5G seems worse is because most implementations are NSA (non-standalone) right now. As others have mentioned, this means you're using the LTE network for control/signaling and 5G just for data traffic. 5G SA improves latency because it ditches the LTE signaling but it's not available everywhere on most operators yet. Verizon and AT&T are just starting to implement it. T-Mobile US has been ahead of the curve in offering 5G SA nationally for a bit now.

However, probably the most important reason 5G performance can appear worse is because NSA works via a technology called ENDC - EUTRAN New Radio Dual Connectivity. This enables your device to receive LTE from one cell site and 5G from another. LTE being there to carry the control/signaling as previously mentioned as well as improve speeds by combining LTE and 5G channels.

When you're receiving 5G from one site and LTE from another. Depending on your device and your network operators settings, more of that traffic will flow over either LTE or 5G. If your 5G channel conditions are poor (say 5G is coming from a far away site but you're also on a closer, LTE-only site), but your device is still preferring to send data mainly over the 5G leg of the connection, you could potentially see worse performance than you would on LTE alone.

MU-MIMO does what you describe and is implemented in WiFi and 3GPP (LTE/5G) standards. Leads to significant gains in spectral efficiency too.

Exactly! And especially if it's provided by a cable ISP. It's just VoIP. Maybe with some QoS on their network and battery backup.

It's not a real circuit-switched network with its own power supply like traditional POTS service.

Listen, SMS sucks (and by extension MMS which is what manages the media sending) but universality trumps all. It's a simple system that despite all its flaws is still available everywhere and used for everything. It's an "innate" technology. Being innate is a feature far more powerful that stickers and read receipts.

RCS is a great standard to replace it but SMS is so ingrained that it wouldn't be gone even with RCS on every phone and every operator interconnected.

I get what you're saying but the UI and UX of email is a wreck and a half even with a good client.

And simple-but-powerful applications like messaging should appeal to the lowest common denominator if they want to be effective and usable.

If you have sparse data, then maybe you shouldn't be making grand comparisons or trying to make claims about the entire world?

It's not saying the study is flat-out wrong. It's critiquing specific aspects of its reasoning and categorization. Not at all comparable to antivaxxers.

It is really weird the original study decided to categorize it this way. Especially because there are potentially drastic environmental differences between say the US and Australia. Same goes for the "Other" category. How are China and Brazil similar?

It's suppose to be on Globalstar's existing network which would be S-band and L-band but CDMA. It's not 5G-NR just yet though that's likely where they're headed.

I think Apple added n53 as part of this deal at Globalstar's request. Globalstar is trying to lease their spectrum terrestrially for small cell networks and network capacity solutions for the carriers.

>It's really amazing that we live in a world where we can have such infrastructure, but at the same time, it's owned and controlled by a single corporation.

I get this sentiment. Globalstar does have competitors at least. Iridium and Inmarsat offer comparable services though not as seamlessly integrated into a popular consumer device.

I do wonder what happens if you aren't paying for the service but have an emergency. I guess they just don't connect you at all? Is there an automatic charge for accessing it?

MVNOs rule out roaming? Since when?

They don't necessarily have to. It can be an always-roaming service. Similar to what JT and Truephone offer.

These scenarios are the case for many Indian people and others working in the US. It's not an edge case. There are no hairs to split when immigration and citizenship status are integral to why people might act the way they do...

Of course, US telecoms would never consider this despite NTT being one of the stodgiest on the planet.

I didn't know Nausicaa wasn't animated by Ghibli! I just assumed cuz it's been promoted with Miyazaki's name on it.

This is a someone common problem with solar flares and cellular base stations. Bit flips cause odd configurations to show up, sites to become sleepy, or even just straight up go off-air. A simple reset fixes them but it happens more often than you might expect.

The author's suggestion of a marketplace for algorithms sounds really cool. Whether it's easily technically feasible is another question entirely but the idea of that level of customization would be really cool. Some of the functionality is already there with Lists (as far as allowing regular users to create feeds and others being allowed to subscribe to them).

I do worry about the political implications of it though. People choosing to subscribe to only their world view would create an impenetrable echo chamber. At least now, there is some crossover. If people chose algorithms that avoided the other side of a debate, it would make things worse. Furthermore, you could have outside influences tricking people into certain algorithms to secure a populace with their beliefs.

>I assume there's no way to specify different QCIs for data packets or even the whole connection ? That's all specified by the closed source radio firmware?

From the application layer? I don't believe so outside of the phone's native dialer/closed source firmware.

>If I'm reading things right, it implies that IMS (eg modern SMS/MMS running over IP) actually uses a different data channel that gets a higher priority?

I believe all IMS traffic is going to be higher priority regardless of if that's voice or SMS. They're both carrier-provided SIP messaging so if SMS over IMS is configured, it would use the same APN, go through the same CSCFs, and get priority. It's all the same PHY connection though. There's not a fully separate set of wireless channels for voice and data like it was in the CDMA standard where there were CDMA carriers for voice and EVDO carriers for 3G data.

You wouldn't be able to just host your own SMS though. You'd need a private APN from the network operator to do anything like that. Other systems hosted by the operator (HSS and MME) are what allow you onto the network.

The main difference VoLTE provides is preferential network access for voice calls. In times of congestion, voice calls will still work when data might not.

VoLTE calls also have a coverage advantage to them over data. Cellular networks have different handover settings for VoLTE (QCI 1/5) where the device can hold onto its RF longer while a call is ongoing and still allow the call to work using techniques like TTI bundling. The codecs used for VoLTE require very little bandwidth and thus can still operate in extremely poor conditions.

And if you're wondering why carriers don't just offer the same for data, it's because customers using data in cell-edge cases would be disappointed with the experience even with the extra handover settings and TTI bundling. That combined with the extra PHY resources being allocated to a situation where data just might not arrive 70% of the time makes it more worth it to allocate those resources to VoLTE specifically especially when they might be critical like in E911 scenarios.

>it's someone with deep mental illness who happened to turn it towards women

I don't think this was just happenstance. You don't just randomly become a misogynist because of mental illness. This kind of hatred is cultivated over time through what you are consciously and subconsciously taught and conclusions you are making about the world around you. That level of hatred eventually devolves into something clinically diagnosable sure but I don't think it's right to say that he just "happened" to direct his hatred at women.

I agree with you though on destigmatizing mental illness and that our systems are not set up to deal with cases like this well enough.

>deprecate the legacy telephone system

The legacy telephone system is being deprecated. All three US mobile operators now have VoLTE (ENUM) interconnection with each other. STIR/SHAKEN call verification is happening between the mobile operators and large consumer VoIP operators like Comcast and Charter. VoIP is far cheaper to operate than POTS and most all operators are using it now and shuttering their legacy networks.

The issue has to do with regulations around the phone system. Rural call completion to small operators is a requirement - as it should be - but has loopholes that encourage abuse. This rural call completion regulation also comes with the ability for small operators to charge certain prices for call completion so they can afford to keep their high-cost rural customers serviced. The larger carriers pay these fees to connect their subscribers to those of the rural carrier.

However, some smaller operators have also been using these higher rates as a means of profiteering by allowing massive amounts of spam traffic through their networks towards the larger carriers.

Praying this startup crashes and burns so I can see what's actually physically inside the fridges again. If I'm in the store, I'm already looking to buy. I don't need more advertising to encourage me.

>To Avakian, it's simply an expected growing pain. Cooler Screens plans to educate >customers about the digital displays and launch features like voice recognition, >so shoppers can ask about prices or item locations.

So unintuitive and user-hostile that you have to "educate" customers about them.

I always find it funny when people like this are referred to as "expatriates" rather than immigrants.

>These specs and the chipsets that are implementing them seem to be deeply maddening

Oh yes. Much to the frustration of even the phone OEMs. Hopefully WiFi is easier to handle than 5G lol

I'd be interested in that! Would be a good learning experience and a way to understand WiFi more deeply. My experience so far is mostly in cellular.

> self-directed health and nutrition research

That's a bold statement considering the anti-vaccine climate today. The value in doctors isn't necessarily what they've learned but instead what trends they've seen personally and local to your area.

I do agree human financial advisors are mainly a tool for comfort. I've got one and most of our conversations instigated by him are relationship-building and not necessarily aggessive-fund-strategy type talk.

From that document:

> As Arm’s CEO, Simon Segars, explained: “We contemplated an IPO but determined

> that the pressure to deliver short-term revenue growth and profitability would

> suffocate our ability to invest, expand, move fast and innovate.”

It sounds like Arm needs a change in leadership to me. Find the capital for long-term investment somewhere and follow a path to improvement like AMD did. Yes, there is pressure to deliver short term profit as there always is today. However, that's not a strategy that works for a company like Arm. Everyone around the world can see the value in what Arm produces. Find someone to invest who isn't a hedge fund manager and still sees that value.

They say that now... It could even very well be the case. However, there are plenty of ways to manipulate those licensing agreements to work more in Nvidia's favor than they do today.

It's gotten to the point where I always feel like I'm "behind" on good movies or TV because it's become so accessible and everyone around me seems to have managed to watch it all. I can't stand it though and often find myself repeating shows out of convenience and comfort.

When I do find new shows I like, they end up feeling more special as well.

Just because the tech is standardized doesn't mean Apple could just fly on their own. The carriers are entrenched via spectrum ownership. It would be impossible for Apple to build a network without the right spectrum.
