Hi. My LtAP mini LTE kit modem is broken.
In our country, the LTE 1700 range is used.
Is it possible to replace the modem on it?
I see that there is this option and this one.https://mikrotik.com/product/r11e_lte7 https://mikrotik.com/product/r11el_ec200a_eu
But there are no frequencies of 1700 in their description.
There are also kits like these:https://mikrotik.com/product/knot_emb_lte4_global
There is an indication here that the 1700 frequency is supported, but I don’t understand whether I need to buy a separate antenna for it.
Can someone suggest what options there are?
Perhaps the modem can be reprogrammed to fit the required frequencies in my country?
Oh, I was wrong.
BAND 3 is still used, although the frequency indicated is 1700

Number, shown with EARFCN, is not frequency expressed in MHz, it's channel number ... which corresponds to 1855MHz. There are many EARFCN calculators available on the net, this one is only one random example.
Thanks! I didn't know about that.
Then, both PCI modems may be suitable.
Yesterday I reset my router. After the reset, the LTE interface reappeared, but it was “inactive”. I was able to remove it
I checked the power supply on the board - 3.3 volts are present.
As I understand it, the modem is connected via USB lines.
I'll try to take a similar device and reinstall the modem.
I replaced the modem with one from a similar device and it worked.
