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.
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.
