It is time to start taking do-it-yourself mobile networks seriously!
AWS today announce their 5G offering https://aws.amazon.com/private5g/. It is targeted for AWS customers in exactly the language that IT people are used to. Order from the console, specify coverage area and capacity requirement ... wait for equipment delivery ... install ... activate, that is all. No dBm or MHz mentioned. It can be made simple for the user.
AWS 5G operates on the CBRS band and is available in the US only. Let's see if it is 5G or dual carrier LTE - like some other CBRS 5G offerings. If you want a do-it-yourself network outside of the US or one which your data remains on your own site, Poutanet can help you.
