Reply to comment by jerseyboiii in JC has hardly any Verizon 5G Ultrawide coverage - way less than Newark (!) by mmmmyah

Getting a 2-gigabit connection on the streets of dense urban areas and in large stadiums and arenas is useful.

Useful for what exactly? Streaming 63 high def videos at the same time while you're walking on the sidewalk?

Useful for much right now other than general speed and responsiveness? Probably not. But you don't build new network infrastructure for today's needs, you do it for tomorrow's.

I agree, but most needs are tied to a building, not sidewalk or roadway use.

I absolutely agree with you, and think we need MUNICIPAL GIGABIT FIBER that competes with private cable companies. And landlords aren't allowed to disallow tenants from choosing their wired internet utility provider (for cable company kickbacks).

I mean, streaming bidirectional AR content running on edge servers would be a good mobile use case that would probably need that sort of latency and bandwidth eventually in a mobile environment.

5G doesn't get better latency than 4G --- only better bandwidth, at the expense of worse / weaker signal.

Doesn't get better latency currently; theoretically, it can cut latency to single-digit milliseconds to the edge.

Are they still touting 5G hotspot connections for home internet use though? Because learning this makes those seem like competing goals.

Probably more of a good idea for suburban environments to prevent them from having to wire fiber to each house. Running a fiber cable to a dense 400-unit building is a lot more cost-effective.

That said, there have been millimeter-wave high-speed point-to-point internet services at commercial buildings in NY and Chicago for years. Just need to put the antenna on a tall building and point it at other buildings.

especially since most poeple will be on wifi in their homes or place of work

Well for one, it's terrible going through structure. It's bad at getting through thin wood framed construction, way worse with steel/glass and masonry which is common in JC. So even if they put the infrastructure in, and they'd have to put way more per square mile here than anywhere else, most people still can't use it unless they stand outside.

Secondly: Internet speeds are mostly a thing to make it easier for sales people to get gullible people to spend more money. Most CDN's limit anyone's connection to websites and services they host to 100Mbps by default, 500Mbps for a few premium services (and I can think of only a handful of things that actually do that). That's not just to control cost, it's the most rudimentary DDoS protection. Nobody needs more than that, so why bother even trying. 95% of what most people do in a day goes through one of the top 10 CDN's.

The highest bitrate 4k stream is about 50Mbps. For commercial services you can just freely subscribe to with a credit card it's 20Mbps (Disney+ I believe is the highest right now with 4k HDR). Even if a dozen people streamed in 4k @ 50Mbps, you're talking 600Mbps + 25% overhead for fun is still 725Mbps.. You're not even at a gigabit, and realistically no household is doing that.

Beyond that, services like Kaleidescape download passively overnight, but I'd bet nobody who's got Kaleidescape is using residential broadband, they've got business service with a proper SLA. So even on the high end: you don't need more than 500Mbps.

But sales people at every ISP now ask how many devices you own, and greater than 5-6 is going to recommend gigabit minimum.

That's where the money is. Convincing people who don't math good to spend more than they need. Do that over a few million customers, and you've got a perfectly legal high margin business.

There's no law requiring them to help you not overspend. These sales tactics are 100% legal and by the books.
