Let me put my perspective, coming from a guy who is involved in private Cellular networking (US as well as other countries): 1) Private 5G can be deployed either with licensed operator (Cellular provider) or in CBRS band (CBRS band is opened by FCC for the private cellular deployment). It can be used free or paid, different options. (Fees is minimal). 2) CBRS still doesnt support 5G. No idea how AWS will provide. But even if it is private 4G, for the end user it doesnt matter. 3) Your available bandwidth is limited by the air waves bandwidth you are using, nit by 4G or 5G. Per enterprise, CBRS band is limited to LTE equivalent band (20MHz). Total CBRS band is 200MHz, if I am not wrong). You are not going to get giga speed just because its 5G. 4) Not all phones support CBRS band. You will be limited to CBRS band support in handset feature. 5) Each end device will need SIM (SIM card either physical or virtual). Its not like your laptop will be connected with private 4G or 5G. You will need modem as well as SIM card (unless your devices support these features). 6) Its really for small geographic reason. Its not that easy to take the equipment with you and start using. (like in car or train etc). 7) There is a concept of SAS server, that's why AWS device needs to be connected to this server in cloud (There are SAS license holders, to them). Once you install the system and that is connected to the SAS server, first you get the frequency band which is open in your area. If some one using that band (another CBRS player), you are out of luck (ask me , who has to call different teams when deploy in lab). PLus, there are scenarios when these licenses can be revoked (if you are using free band). The law enforcement can ask FCC to use the band temporarily. GCC can revoke your lic and stop the system. What AWS did is big, but for enterprises.

Is thei FAQ in line with your understanding? You might be more capable than me at parsing it for all I can understand is: "You will receive all the AWS Private 5G hardware (including SIM cards) and software you need to deploy your private cellular network and connect devices to your applications." I translate that to: we sell 5G access points as an alternative to wifi access points. Am I wrong? Cause if I am right I fail to see the bigness of it. I just see it as something reasonable. https://aws.amazon.com/private5g/faqs/ https://aws.amazon.com/private5g/faqs/

  You are on right path. Its of no use for consumer. Private 5G cant compete against WiFi with current ecosystem. The end devices dont support 5G modem (or 4G). It cant compete against WLL (Wireless in Local Loop) (Means Wireless based broadband service). As you need dedicated internet service to configure p5G (private 5G) and to let it remain active, there is no business case for p5G for broadband service/WLL. There is another service, FWA/Fixed Wireless Access, by different 5G provider where you get a receiver which is connected to home router. Good question is, what this hype of p5G: 1) Industrial area coverage: Where you need 50 WiFi radio unit, you can provide service with 3-4 p4G/p5G radios. 2) Hazardous areas: where you cant provide the networking at all the corners or areas, one p5G radio blast area (esp with beam technology) can provide the coverage. 3) Security: Mobile phone systems are based on shared secret and proven to be secure in terms of access compare as well as on air to other technology. 4) Packet loss: Less packet loss compare to WiFi (believe me, its big deal in Industrial world) 5) Compatibility: what's a negative for 5G modem (not many devices are available), is positive to some extent. Once investment is made with 5G modem, the device can be on road too. THink like, acting like enterprise node in p5G area and limited services outside (or device consumer). 6) Edge computing: With new standards, the applications can run at the edge. Those can be done currently with WiFi too. But WiFi has limitation of devices counts (too many needed), path reliability and geographic coverage. Whole factory or port or airport can be covered with small p5G footprint with specific applications running at the Edge (I live in this world :) ) p5G will be game changer in enterprises with large complexes with moving assets.

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 there. Search for Hannover Trade fairs private 5G where its deployed for Edge computing and secure industrial app ecosystem). In terms of bandwidth, p5G will not provide any advantage over WiFi esp WiFi6. Its the enterprise level ecosystem where its going to be huge differentiator. Regarding your point of tower level handover, that will not be an issue. It should not be in pLTE (p4G) too. But I can understand in earlier versions, the systems might be feature limited. Are you sure it was local 4G service line p4G or Femto service where operators provide small device to cover either indoor no-RF spots or to move the traffic load from network to public internet/network.

    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 [1]https://www.gsma.com/spectrum/resources/6-ghz-for-5g/ https://www.gsma.com/spectrum/resources/6-ghz-for-5g/

      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.
