RB411UAHR with Sierra Wireless MC7710

Hardware MikroTik hardware general

Hi guys,

while the module is now officially supported, I wonder what speeds you are able to achieve.
I got the Huawai B593 here as well and I can achieve up to 60 mbit with that unit.

The Routerboard setup is able to deliver maybe up to 20 mbit,
but I never saw anything above that. So how are you guys doing and is there a trick to make it faster?

I already put a more powerful antenna in the setup which helped a little bit,
but not that much.

Maybe there is a firmware upgrade from Sierra Wireless that helps?

Thanks!

Kind regards,
Daniel

i’m using an rb411U and mc7710, I get a throughput of approx 30-35Mb/s with signal-strengh: -69 dBm on my carrier.

Thats quite a bit more. Which firmware version do you run on the module?

With my 9dbi antenna I have roughly -58db and sometimes even better, so I assume reception is not the problem.

Do you use the auxiliary antenna?

PS: added a screenshot of the lte interface status.

Nope, i dont use the aux antenna. your signal is great, i dont think that is the problem.

What does your cpu look like when you’re pushing it ?

Thanks for your input, sadly it is not the CPU useage. I wonder:
does your setup connect to LTE by itself, or did you set LTE in the interface?

Kind regards,
Daniel

my lte interface existed when the modem was installed (i believe it prepopulates since around ros 5.14 or so). modem set to use direct ip and a dhcp client on the lte1 interface.

i’m not too sure what could be the problem, maybe post your /export and we can take a look ? silly question but its the same frequency and carrier as your Huawai B593 right ?

Sorry my ignorancia, but would be possible we use the LTE as AP for we transmit signal to phones without use Wireless?
