I'm using Mikrotik RBLDFR&R11e-LTE6 as my LTE modem.
BTS which I have my signal from supports B3 and B20 band.
My modem in CA mode always set B20 as a primary band, and B3 as secondary:
It is resulting in that I have aggregated download speed (B3+B20), but upload is working on B20 (slow):
When I turn off CA, and set only B3 band (so it is primary) my upload speed is x3 times better then on B20:
What I would like to do:
- Set B3 as a primary band
- Set B20 as a CA band (secondary)
What I do for now:
Type in terminal:
Code: Select all
/interface lte at-chat lte1 input="AT*Cell=2,3,,1474,136"
Code: Select all
[rafal@MikroTik] > /interface lte at-chat lte1 input="AT*Cell=2,3,,1474,136"
output: +CGEV: NW PDN DEACT 5
That makes B3 as primary band, but B20 won't connect as a CA band (secondary):
What can I do, to set B3 as primary, and B20 as secondery?
I tried to update:
RouterOS from 6.49.6 to 7.4
modem firmware from V025 to V033
It did not help
