Well, it is faster and more stable too. Bm818 couldn’t reach the potential maximum.
Interesting point. I’ve been so caught up on having a stable modem (the bm818 has never worked well for me here) that I’ve yet to do much testing. I’m pretty sure the actual connections - especially data - is via LTE (at better speed and stability than before). 5G comes from how the system sees it as it identifies if it’s connected via 3G, 4G or 5G (looking at upper left corner of screen). My settings are automatically “3G, 4G, 5G (preferred)” and it never drops from 5G. What I’d question here is that, due to L5 antennas, it must use the freq areas same or close to 4G (as the 5G special frequences are not available - but those are only part of the whole) but it’s using 5G protocols and algorithms to manage the signals, datastreams and network use.
When I now tested it, it still retains network connectivity but gives no 5G marking when selecting “5G only” and voice call fails. It does give 4G when selecting “4G only” [meaning also that if someone wants to limit the modem not to use 5G, it works well without it]. yet, when I select the “3G, 4G, 5G (preferred)”, it shows 5G for network. This seems like the logic is that 5G can not function without 4G (probably due to Volte needing LTE data), at least in this network. As for further testing, I’m open for suggestions (of the previous, number one done, two is a bit redundant, three is not possible) but I think more can be learnt if we’d understand how the system interprets 5G (what does it - or standards regarding 5G - consider to be 5G in order to show that symbol).
[edit to add: quick test with using ANT1 too (and additional external antenna) didn’t produce anything new on 5G so I surmise that having extra antennas does not bring 5G - it’s something else (extra antennas are not connected to frequencies or bands available, they are separate channels if I understand the manual correctly). A slight increase in DL speeds - even a bit over 200Mbps single temporary peak.]
Same with bm818 (it has three antenna connectors) and most other modems as well.
