To understand 4G+ (4G Advance) / CA

[Faraz_F34_5G]

Those who want to know what 4G Advance is 4G+ ( most M series & lower end A series don't have this ) is upto 4 times better than 4G.

M30s has Carrier Aggregation but it doesn't show in the mobile. Does it need a firmware update.

[Faraz_F34_5G]

unfortunately M series don't have same modem with A series smartphone like A50, A50s or A51 on same processor SoC.
M30s has LTE category 4 modem which does not support CA as confirmed by IamSRV.

i am using m30s ur saying is correct
internet, gps, call clarity everything worst
network always poor even in 4 bar showing

in my a50 it shows 4g+ sometimes

[Faraz_F34_5G]

Yes, A50 supports 2CA with 3 different combinations.

[Sanskar]

pls explain 🙏🏼 I literally don't know anything about CA or as u said 2CA

[AMPK]

See CA is your mobile will receive multiple connection from different towers at the same time like 850, 1800 or 2300 band frequencies. This will help in better connectivity and reception.

okayy now I got it. thanks🤗

[Faraz_F34_5G]

3G and 4G already have smart switch between nearby tower & no not a single device on earth can be connected to two transmitters/towers (what @AMPK said is completely wrong). Dual transmitter can only be connected from two WiFi routers in WiFi 6 & 6E only.
I cannot explain you modulation of frequency, but it's been done since 2G or FM radio.
CA takes it to next level.
Lower frequency bands can penetrate further, so it got long range but very slow internet speed.
Higher bands above 1800 MHz can carry more data i.e more speed. but can only penetrate a few blocks of building.
CA combines a low band & a high band to full both the needs.
Their are a few more technologies involved with 4G Advance like MIMO (multiple input multiple output) or QAM.
but that is no concern to consumers, we just want 4G+ in 2020 & later and a little bit more stable Network and speed.
