B618-65d carrier aggregation questions

[Lishen23]

I've been using a B315 with a XPOL 6 antenna for about 6 months now, and today I managed to get my hands on a B618, I didn't get the sma to ts9 connectors yet so I cant use the XPOL, but I fired the router up anyway and I'm getting around 60mbps with a pretty low SINR. I was getting around 35-40mbps with the old setup.

Anyway I have two questions. Is there any way to force carrier aggregation on all the time? I noticed it only kicks in when I do speed tests, so I assume it kicks in when bandwidth is in high demand. That would be okay except I just did many more speed tests and I get about 30mbps down now with no carrier aggregation, so I'm worried it wont work consistently when I need it to.

Second question, if I get the sma to ts9 connector and hook up the xpol 6 to the B618, will I still get carrier aggregation? I'm fuzzy on how the whole CA and MIMO thing works and I'm worried that the two antennas in the xpol 6 wont be enough to do CA.

Seems to "lock" to 4G+ once you begin moving a fair bit of data and will stay like that if u keep using it. 2nd q - yes.

No way on B618 to force CA, all the devices I have used show the behaviour you described, I believe its a power saving feature (The switch to the 2nd band with CA happens in a few ms, the web interface has a delay though)

On my B618 once I do a speed test/download and get 4g+ it tends to stay there

Perhaps because of the low SINR you describe it cant always hold the CA

Afaik CA and MIMO are separate so you should still get CA on the xpol 6

Telkom runs 4G+ on 2 ways. Band 40 x 2 and Band 1 + Band 3. You can force band 40 via the control panel by selecting 2300MHz.

If you want to force the other 4G+ you would need to use the huawei band tool to force 2100MHz + 1800MHz

Is it possible to force 2300 down and 1800 up? I have been trying but when I run the command, it runs 1800 up and then closes on 2300 +1800.

If you leave it on Auto it should be able to do it but does not work that well. I find that the download is on 2300MHz and as soon as it uploads it drops to 1800MHz but it sticks to 1800MHz after that it does not want to go back to 2300MHz.
