I haven't researched it fully but to me it seemed like a utopia.. For the device makers, and dystopia for the customer. Imagine all your wireless IoT except you can't block them or filter from the wifi network, they are always connected and you can't see what data they're sending.

Don't buy them then? It's not like you can control most IoT today

> Don't buy them then?

Tech doesn't work like that. Good look buying a high end "dumb" tv or a high end smartphone with a jack 3.5. It always starts with "don't buy them" until there is no choice anymore.

Not for me. I've owned every smartphone and high end feature phone since the 90s. A Blackberry was still better than an iPhone + IMAP + EDGE in terms of subjective speed. Mobile websites sucked hard on the iPhone. (Don't even get me started on Pocket IE and the IPAQ). Quite literally my day job was Windows CE development, I was on the W3C XHTML/CSS/XForms committees, I worked on implementation of those specs on HW be…

I wonder what product you were using labeled "iPhone". Mobile Safari was head and shoulders above other smartphone browsers. It handled mobile sites of the day without any issues in my experience. It was nothing like other mobile browsers. I went through just about every family of PDA and smartphone before the iPhone came out. Their web browsing universally sucked. The iPhone was a huge leap beyond other mobile brows…

Mobile Safari wasn't the problem, EDGE was. Yes, YouTube was shipped with the 2g iPhone, but it was unusable without WiFi. YouTube over edge is 144p potato vision with frequent buffering. Perhaps your tolerance for this is a lot higher than most consumers, but latency studies show people abhor it.

>clicking links being agonizing is either fiction or hyperbole.

Web 1.0 over EDGE is agonizing in latency. Without Javascript, every action that isn't a #anchor in the same page becomes a round trip. If your radio has gone to sleep, it takes even longer. And I was being charitable giving you EDGE, in 2007, many people were still on GPRS.

It's absolutely self evident that faster networks enable entirely new applications, just like increased memory beyond the 640k limit enabled new apps.

I bet google wont implement that part... Just like they didnt implement ad-hoc wifi

Wifi direct is definitely implemented on android, not sure what you are specifically talking about?

Look at this thread: https://issuetracker.google.com/issues/36904180

The latency is only reduced from tower to phone right? The tower still has to ping the rest of the network to find the service you were requesting to in the first place. If total latency ~ 500 ms, phone-to-tower is maybe 50ms of that in 4G. Even if it's down to ~1ms, total latency is only down 10%. Not a networking expert so maybe I'm missing something here. Perhaps better use of CDNs could make this much faster?

> phone-to-tower is maybe 50ms Maybe 50 microseconds, not 50 milliseconds. 1/1000th of what you assumed. Towers are typically up to a few miles away in dense areas; they don't work well beyond 15-20 miles from the cell phone. Waves go 186,000 miles (or 300,000 km) per second. Assuming a 10 miles distance from phone to station, it takes ~25 microseconds to do the trip, which is ~50 roundtrip. So, in other words: laten…

That's assuming latency is entirely due to propagation delay, in which case obviously a change in technology wouldn't help. Latency isn't entirely due to propagation delay though.

Your mileage may vary but verizon 5g home for example does not have a data cap [0]. [0]: https://www.verizon.com/support/5g-home-faqs/

No company or plan has ever gone back on unlimited promises.

No company has ever defined unlimited to be, "really fast for a little bit, then really slow."

I have "unlimited". In the sense that I have a daily 5GB cap, if I hit that I have to manually trigger 1GB more. But I can do so as much as I want.

I have (as far as I can tell) truly unlimited, including tethering. When we had trouble getting a fast connection to the house, for a couple of months we just hooked up my phone to the router and burned through 100GB+ per month, with not a squeak from the provider. These deals seem to be getting more common here in the UK, and I pay around £20 per month for it.

It's €25 here for unlimited. So only slightly more expensive after conversion.

I really hope they'll drop the daily "limit". They can't legally complain about tethering here. But the daily abuse limit is just an annoying thing.

It seems to me like Uber doesn't depend on high bandwidth or sub-second latency.

It's high bandwidth compared to the standards of the time they're discussing, not by the standards of today.

Uber would work just fine using WAP/GPRS.

Adams is the worst kind racist bigot. Hiding his true face behind "testing the limits", "trolling", and other seemingly clever "unconventional ways of challenging the social norms". That's just the manipulative narrative to make the highly toxic and divisive racist drivel he is peddling more palatable to the more moderate of his fans, who typically fail to see who he really is because their perception of him is frame…

I do not agree with this assertion. Adams has also claimed twice to have himself been a victim of direct, stated-to-his-face discrimination on the job.

Which supposedly should justify his own racism, and presumably gave birth to his unwavering support for the Orange Idiot, down to dying on the hydroxychloroquine hill, the most idiotic of all.

It's hard to deliver both higher speed and longer range, because higher frequencies don't reach as far and don't penetrate walls as well.

But what I read about 5G is that its range is comparable to wifi. Why do they do that?

AFAIK, the speed is >gigabit fast, but to achieve that speed you need to have super high frequencies and hence smaller range.

To me, it seems inconvenient as a replacement for 4G. However it is also being used for other applications; like self-driving cars[1].

> As I’ve learned more and more about 5G Out of curiousity, what's a good source of information on 5G? I assume the standard itself is not the easiest thing to digest so I'd appreciate your input.

Yes, the 3GPP or ITU standards can make for a dour read. Probably best to look for sources that you find engaging. You can start with something that gives you the basics, and/or just go straight to the vendors ─ who provide a plethora of white papers, case studies, industry insights etc. https://5g.systemsapproach.org/index.html https://www.ericsson.com/en/5g/5g-for-consumers https://www.nokia.com/networks/5g/

Stranger, your links above were very helpful for me in formulating my company's strategy in 5G. we are a big well known player. How can I get in touch with you for a more in depth conversation?
