Earlier quoted context omitted.

Tacoma, WA is planning on deploying a private 5G network to make port operations more efficient. You can imagine containers coming in and out of ports are slowed when someone has to physically inspect them for damage. There are a few companies using AI to detect damaged containers and having a higher bandwidth allows those images to be more clear which in turn allows the AI to be more accurate.

But it wouldn't use high band! So, why not just stick with 4G devices (cheaper, more tested), and existing solutions?

Not sure I agree here. 5G offers lower latency and more bandwidth. Also, what I've outlined is just one use case. If we're talking about a port there are multiple layers of operations in which a high speed network could make things move more efficiently. So while 4G might be less expensive it also would only incrementally improve current operations. I would imagine this is the same for other use cases in which there are multiple layers of needed high bandwidth.

Sounds like they are selling Wifi++ - what confuses me is how/why Amazon is involved, apart from selling the hardware. Is there a subscription piece? The implication of this product concerns me, although maybe it's just a communication issue. Amazon is selling this as an Amazon product, but wifi isn't an Amazon product, nor is 5G. They are retailing the gear to put up a 5G network - so why call it a "product" and rol…

The 5G architecture (and LTE for the most part, but 5G was designed ground-up this way) makes very heavy use of remote resources. An actual 5G base station (and most new LTE base stations) is somewhat like an SDR with very little actual protocol logic locally, it connects to a remote controller that handles all of the "business logic." It's an important change because for various reasons, some good and some not so go…

Thanks for the clarifications! I still have questions - there is no "business logic" in my wifi router, so why would there be such a thing in a 5G base station?

What is the analog to a wifi router calling out to a "remote controller" to handle "business logic"?

A base station needs "support services" to function - what are those?

Presumably the complexity of 5G vs Wifi comes from it's cell nature, and the nodes need to know about each other and connected devices to deal with a handoff (which implies at least limited multiplexing). But I don't see why this behavior would require a server-side component and a subscription. Shouldn't the 5G nodes be smart enough to deal with this without phoning home?

Spectrum questions aside (which obviously one of the biggest one), could this enable running Helium 5G on AWS? -- Edit: I don't own any Helium, just curious from tech side what this new AWS service could offer. Not sure the downvotes are particularly about Helium or any crypto related discussion.

Why do peole care about helium so much?

Or because it solves an incentive problem which has kept millions of people with sub par networks to choose from.

Become a telecom as a service! Super cool. For those who are glancing over, this is a big deal. 5G isn't really like 4G upgraded. It's more its own thing. I believe this has been available though for a while and many telecoms have partnerships with FAANG beyond Amazon. With 5G you can essentially split a network into multiple partitions and scale them independently on-demand called Network Slicing. (like cloud comput…

> 5G isn't really like 4G upgraded. It's more its own thing. This is my understanding as well, but I have no idea about any of the details. I know there's something cool about "beams". Do you (or anyone) have a good "entry-level" article/doc that outlines some of the major features that makes it so different than 4G?

Search Massive MIMO, Beamforming ( Which isn't really new ), Small Cells, NR.

That is about it really. You can ignore mmWave which is pure hype. Most of the other enhancements are on the carrier / operation side and not consumer.

You can also ignore all the 5G Self Driving Vehicle crap.

Probably a small outpost deployment + RF gear, so (guessing) $500K up front and $10-20k/mo. I don't know if it's possible to get RDOF grants for individual communities but that might cover some of it.

In addition to the gear, would you have to license the spectrum from someone? I think the fcc already auctioned it all off? Or does that not apply here? Any idea what that would cost?

I don’t know the details there. Presumably there would be at least be cost for someone to maintain the paperwork and equipment certification. There’s a couple comments in here about this being on CBRS, possibly more info there.
