How do you provision devices (eg eSIMs) to run on this network?
using an API to order eSims from an eSim provider like oasis (now tata) and register it in your core network ?

#32It would be interesting to have some practical application for it. I don't see a point in building such network, unless you can use it for something.
here is one, let me know what you think about it:
Someone to rescue in a mountain, rescue team needs to be sync and rescue machines (drones) to be operated in this hostile area.
Just send a drone to run a dedicated 5g network (like a flying wifi AP) and you gain a 5G data link between humans and machines in minutes.
A tactical bubble.

Campuses like universities could use iot networks in low frequencies which will be much more reliable than Wi-Fi because of range problems.
Use the networks for what? Maybe I've just been out of school for too long, but I can't think of anything particularly interesting a campus would want an IoT network for beyond maybe motion sensing for automatic light turn-offs and run-of-the-mill security systems. I can't imagine a low-frequency IoT network being good for broadband access for people walking around (a la wifi) because of bandwidth limitations.
"campus" can mean lots of things... your handle is "vineyardmike" - what about irrigation / water / temperature / other sensors spread over a vineyard?

short answer is no, but the frequencies aren't far off wifi operates at 2.4Ghz most typically and also at 5Ghz (shorter range but faster) 5G will be ranges of frequencies, depending on jurisdictions, but typically between these two frequencies which are the sweet spot for domestic usage in the US, 5G carries AFAIK have ranges between 2.5Ghz and just under 4Ghz in the UK we have EE, O2 and Three operating ranges aroun…
It always amazes me how pulsing some electricity into a wire at a specific frequency can get you arrested lmao. I really don't understand why there's any legislation at all covering anything above 1GHz where there's enough bandwidth for literally everyone to do whatever they damn well want and not enough range to do any damage at all.
There are satellite comm frequencies above 1ghz that you could easily jam from a more powerful terrestrial transmitter, like gps.

#35Is there anything one can actually do with a home-sized 5G network? As an individual, without being an actual telecom operator and all that.
I was going to say OFDMA and MUMIMO but wifi 6 got that covered

Literally my wifi goes down when my microwave turns on... there are reasons regulations are put in place

#37Systems Approach has a new book on Private 5G [1], with a hands-on implementation example in the Appendix [2]: [1] Private 5G: A Systems Approach: https://5g.systemsapproach.org/ [2] Hands-On Experience Appendix: https://5g.systemsapproach.org/software/overview.html
There is also a substack: https://systemsapproach.substack.com/ This weeks post covers the same thing as this post - how easy/difficult is it to actually set up a private 5G network compared to a similar WiFi deployment.
Thanks, yes I'm subscribed to the newsletter as well, what a surprise coincident when posting about open 5G on HN and receiving article exactly in the same subject later on the same day.
The direct link for the substack article is here:

Currently New York and Dublin are also using open source private 5G networks for their Smart City initiative:

#38Probably related, is it possible to create my own eSIM?

#39Really interested to see if this will get picked up by network operators and how. In my experience, corporate buying at this level has always been the home turf for salesmen of entrenched companies, partly because they actually pitch better and partly because buying StandardCorpX's product comes with a level of delegating design decisions you could get blamed for to the supplier. That last one typically doesn't come…
Network operators are the ones driving O-RAN - they have the most to gain: cheaper equipment & more supplier options. However interoperability is not as easy as you might hope, even with an open standard.
>However interoperability is not as easy as you might hope, even with an open standard.
Came here to say this. Rather than being all interoperable / plug and play, you wind up having to validate different combinations of hardware from different vendors... which then has to get revalidated when new versions of software are rolled out.
