Hello

I have a question.

I need to use two EC25 for IoT purposes (=always on, low volume of data transmission required,...).
Although the EC25 has two antennas inputs (MAIN=TX/RX and the second DIV for RX only), I only need to use the MAIN.

Question:

Can I use one unique MIMO 2x2 antenna (=each ...

Thanks, I will try it out.

Hello

Is there a doc available somewhere that lists the supported AT-Commands of a DW5821e???
I couldn't find one :-/

Thank you

I am a bit skeptical of 4x4 MIMO, as LTE likes spatially diverse antennas, by at least half a meter, so a 4x4 is a mix of compromises; cost, space to mount, and aesthetics.


Is that true for polarized 4x4 MIMO also?

Because on the Poynting youtube channel, there is a video about antenna spacing ...

Oh that doesn't look good at all

Hello

Has anyone a WiFiX AD4M or QuPanel 5G/LTE MIMO 4x4 (4G/5G 4x4 MIMO) antenna? (they are the same)

Hello

I have a question about the EM160R.

This modem is using a Snapdragon X24 modem.
Why is it limited to 1Gbps DL ( 5 x20MHz 256QAM) and 150Mbps UL ( 2 x20MHz 64 QAM), although X24 is capable of:

- 2Gbps DL ( 7 x20MHz 256QAM)
- 316Mbps UL ( 3 x20MHz 256 QAM)

Are there other components (radio ...

Hello

Currently I have a Mikrotik LHG LTE antenna/router. That device is supposed to be installed later on the rooftop. It has a major downside... you have to climb up there to change the SIM card...

I could design a PCB M.2 adapter with an eSim on it. BUT I have absolutely no idea how to ...

I have yet another question.
(I don't know if it worth to open a new topic)

Assume you have a very high gain 2x2 MIMO antenna (like a modified Mikrotik LHG) and, let's say, a standard mid/low gain 2x2 MIMO or even omnis, to form a 4x4 MIMO configuration (+/-22.5° each).

Could the modem deal with ...

Oh, that's great

Thanks.

Thanks for your answer!

Where did you find that instruction, or rather, parameter: AT+QCFG="lte4x4mimo/disable",1 ?
I couldn't find it in the AT commands manual

Hello

I wanted to purchase an EM160R card which is a 4x4 MIMO modem. But currently I still only have a 2x2 antenna which I may upgrade later.

I have the following questions:

Q1 : In case of a 2x2 MIMO antenna, on which ports should I connect the 2 cables? One ...
