the article doesn’t answer the question. Why setup an expensive private 5G network instead of a private wifi lan, also considering wifi maturity and wide support?

Because if you need a private 5G to solve your own supply chain problems, why not set it up so you can also make money off of it.

so I guess the question is: why can’t one use wifi for these “supply chain problems” ?

Concerning your point 3) - Few years ago I was a bit excited about Local 4G, but commercial units sold back then could not handle tower handovers, and were very limited in bandwidth(5MHz/~10Mbps down, if I remember right). Has it improved, or if it hasn't, is it going to really offer significant advantages over Wi-Fi...?

As I mentioned, bandwidth is proportional to available access/RF bandwidth (Shannon's Theorem). Current available band in US (CBRS) is limited to 20MHz per user/enterprise 9I think for enterprise you can go higher, but its still limited). FCC hasn't updated the standards (CBRS) for 5G. Germany is way ahead in p5G (trying to keep the leadership in Industry 4.0/Industrie 4.0, I am not sure what's the available band the…

Isn't there a huge debate going on for the 6Ghz band between WiFi vs 5G? [1] This could end up being used for home & private networks

AWS for telecom will be really opex heavy, though its a boon for small players,MVNO etc but who wants to keep paying aws every month for something they are going to run for ever.

It seems everyone here is confused. Here's the official FAQ, and it has 0 marketing garbage. https://aws.amazon.com/private5g/faqs/ There's no "telecom as a service", and there's no "5g can be split into multiple networks" nonsense. Amazon is just selling 5g access points and hardware (just like you would install wifi), and rents you a private connection for that hardware to AWS, and management of that network from A…

Spot on. This could be a game changer for us ($xB 100+ year old manufacturing company), where we are on a long, slow journey to digitize every piece of manufacturing (long and slow because manufacturing runs almost 24x7x365). Wifi, even the top enterprise systems, is not as resilient, cheap and quickly installed as we'd like. So now I can use 5G instead, and template and deploy it via the cloud? Yes, yes! We'll put t…

"deploy it via the cloud" doesn't actually mean anything and confuses people. You still need to set up hardware at your own enterprise! It's NOT the same as renting a VM in a datacenter and "deploying" it in the cloud.

Sure, it might have a good UX and not require as much expertise to manage, but it's not "deploy via cloud". That's just marketing.

That's not the way AWS typically prices things--my guess is the hardware and setup costs will be baked into the monthly service charges.

Generally yes but outpost is a little different: https://aws.amazon.com/outposts/rack/pricing/ Either way this is just a guess :)

Even with Outposts you're not "buying" the rack (Amazon still owns it and takes it away at the end of the term), you're just committing to keeping it long enough for them to make money on it. The choice of paying upfront or paying monthly is roughly the same money management strategy available with any AWS service (e.g. EC2 Reserved Instances), and likely is more about lining up with capex/opex decisions than actual cost savings.

That's the different domain. 5G standards are defined for Licensed, unlicensed as well as non-mobile world (means the core network can support all the different access technologies). CBRS is licensed band, just free to use but you have register. 6GHz is new band opened for unlicensed spectrum. It will mostly be used by next generation WiFi (may be WiFi 6 too). Any other technology can use that band too and 5G standards may enhance to support this band or may define other technology too. Just last month, ITU accepted the DECT (remember cordless phones) technology to be part of 5G ecosystem (5G core will be able to support devices with DECT air interface). But CBRS band is different and its more about similar to current mobile ecosystem but in private domain.

CBRS cant be used for WiFi or other technology (only 4G in US at this point, most probably 5G in future.. 3GPP defined OFDMA based air interface). 6GHz is unlicensed and mostly will be used by WiFi.

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…

None of this is really what this service is intended for. If you read the whitepaper, they list examples of what this would be useful for; namely, covering your own space with your own 5G for your own devices. Deploy it in these areas instead of WiFi: 1. A stadium's remote ad/video/informational displays 2. A logistics distribution hub's stock-tracking robots/systems/handhelds 3. A corporate campus's smart displays o…

So will 5G actually be better than 5GHz WiFi? I'm not too concerned about speed but rather a stable connection.

So here's the thing, currently I have 2.4GHz and 5GHz WiFi in my home. Any device that is stationary connects to the 5GHz one and any device that moves around connects to the 2.4GHz one. Why? Because initially I had everything on the 5GHz network, but noticed if I move around with my phone/tablets/laptops (even as simple as standing still and turning around), the connection would become unstable/choppy and introduce some lag and in rare cases a drop in connection. The 2.4GHz one works no matter what I do in my home. I can also get 2.GHz all the way out to the curb and it still works, where the 5GHz one drops significantly once I'm outside my house. In some cases it will still show the 5GHz one being connected but any app that tries to use it just hangs and never loads whatever it tries to fetch. So the 5GHz version of WiFi has been utterly useless to me, thus I'm only using it for devices that I know have decent line of sight, are within certain distance and aren't moving around. I currently have no Bluetooth devices chatting in the same airspace and I've tried it with single network too (only 2.4GHz enabled or only 5GHz enabled) - still the same. It could be that there is interference from neighbors: I can see quite a few WiFi networks of neighbors, most have both frequencies active - but I also had the same issue before I live in this specific house. So if 5G can improve the situation, that will be pretty great.

I'm still kinda of confused... does that mean we could say get a simcard and make voice calls via this network? insert sim card into mobile phone android/iphone and make phone calls?

Starting from LTE, there's no distinction in the network level between data and voice or SMS, it's all just IP traffic. The voice call protocol is called VoLTE. As long as your handset can reach the VoLTE infrastructure via IP, you can make and receive calls.

This actually works already over WiFi too and that's called VoWiFi. That does not support handovers between networks though, so it is not that convenient. Specifically it means that if you walk outside the WiFI network, your call will drop. I suppose the different branding is due to this quality aspect, as there's no difference in the protocol.

To have VoLTE or VoNR (the 5G version) the SIP based software handling your calls needs to interact directly with the software stack managed by the operator via a bunch of other telco protocols. I don't think you will be able to support "regular" calls/SMS without if it is not supported by amazon.

Is there any reason it _couldn't_ become that?

Wifi adapters are cheap and everywhere. For 5G tot surpass wifi it will have to match that. Laptops with 5G are not that common yet. ESP like controllers with 5G I haven't seen yet. One of the advantages is 5G operating outside of the ISM bands. That helps a lot with stability and preventing interference. It also means this is not for individuals in their home. If licensing is made so accessible that people at home can use it you will again get overlapping frequency use and increasing interference. If it not made this accessible I don't see the availability of cheap clients solved because the market will be limited.
