LTE Cat and LTE Carrier Aggregation / Bands Support of RN7 connected mainly to built in Snapdragon 660 MSM8956 with X12 LTE Modem Features (also in Snapdragon 63x/66x/820/821): 3CA Downlink and 2CA Uplink, LTE Category 13 (uplink) 12 (downlink), Download 600 Mbps Upload 150 Mbps. So far unclear if device drivers fully support this in RN7.
See also about the same topic in Xiaomi Redmi Note 6 Pro Thread.

So far for LTE Bands I found this - always difficult to see if (also) International/Global version:
GadgetsNow: TD-LTE 2300(band 40) / 2500(band 41) FD-LTE 2100(band 1) / 1800(band 3) / 900(band 8) / 850(band 5) / 800(band 20)
techwafer: LTE band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 34(2000), 38(2600), 39(1900), 40(2300), 41(2500). LTE-A (3CA) Cat9 450/50 Mbps.

Checking the Bands for my provider Central Europe (in bold supported): 3CA (B3+B20+B7+B1) and 2CA (B3+B20/B7, B1+B20) + B32. So CA seems very fine!
LTE General: Cat9 450/50 seems not so exciting compared to RN6P with Cat12/​7 (600/100 or 300/150?) because the upload could be higher like Cat10 (450/100), Cat12 (600/100), Cat14 (400/100)?

Ok, so there it is stated what I already wrote earlier (I bolded those important to me, all except of B32 supported):
Quote:

FDD-LTE B1/2/3/4/5/7/8/20/28
TDD-LTE B38/40

No mentioning of LTE Cat or Download/Upload Speeds.

So has anyone tested and confirmed LTE-2CA or LTE-3CA really works with RN7 ?
whether the CA support for RN7 is interband or intraband or both ?
and what CA bands are supported ?

am hoping for (B3 + B7) or (B3 + B7 + B8), different countries/carriers have different CA bands.....so would be good to know what CA bands are working/supported by RN7.

so if anyone got LTE-CA working.....please post here to share the bands info

Bonjour, je vis en France à Angoulême et je peux vous confirmer qu'avec un Redmi Note 7 Version Globale (4go de ram / 64 go de rom) je n'ai jamais la 4G+ avec Orange.
Fréquences 4G à Angoulême : B3, B7, B20 (1800, 2600 et 800 MHz).
J'ai lu cependant sur un site que le carrier agregation fonctionnait avec le Redmi note 7 uniquement en 2100+1800 mhz (en interbande) mais malheureusement je ne peux pas le tester pour l'instant.

Bonne fin de journée
