another question about LTE BAND

hello ,
I have ask here about the band
http://forum.mikrotik.com/t/lte-interface-what-does-bands-3-7-20-mean/90363/1

and i know the modem (MC7700\MC7710) can work with this terms

but when I try to change I can’t see nothing
if I use this command

/interface lte set lte1 band=20

I don’t get any replay or error
and in the LTE interface - I don’t see any change

why is it?
how can I see if the change have change?

Thanks ,

that band command change is designed for different products

so it doesn’t work on the MC7700?

can you tell for which product they do work ?

Thanks ,

I suppose that its only for the new SXT LTE but it only works on band 3 an 7 with 15mhz channel providers.

In http://forum.mikrotik.com/t/lte-interface-what-does-bands-3-7-20-mean/90363/1 Kristaps explained that the command was only for the specific mini-pcie card he linked to.

The 7700 is a North American card and only does LTE bands 1, 4 &17 so even if the command worked with the chipset in the 7700 it couldn’t change to a band it doesn’t support.

The 7710 supports LTE band 20 among others.
