RBM33G + 5G

wintaeh · Mon Aug 09, 2021 4:04 pm

Hello MikroTik-Users,

we use the RBM33G as our main mobile router in our cars.
It works really well with two LTE modems in the PCIe slots and appropriate antennas. The default route switches to the one with better signal - awesome!

Now, we want to go for 5G instead. Is somebody already using 5G with MikroTik? Does a 5G modem exist, which is supported by RouterOS?

Is it even possible to connect a 5G modem to the RBM33G? 5G modems always come with a M.2 connection. Does it work with one of the SIM-Slots on the RBM33G or do I have to use an adapter from PCIe to M.2 to get it to work?

Any suggestion or idea would be awesome.

Thanks!

I just want to let you know, that this idea is possible.

I successfully connected a Quectel RM500Q-AE with a generic PCIe to M.2 adapter.
At first the module did not show up in the interfaces menu but after updating to ROS 7 it showed and works now.
The sim slot on the RBM33G is also working with that cheap adapter.

I attached three little antennas on antenna port 0 to 2 (the last one is only for GPS, I think) and successfully received data over a 5G station.

I hope, someone could get some value out of this and reactivates his RBM33G.

Tschüss!

Totally off topic because i couldn't find the mail button to do this in private, but how do you make the switch to the card with the better signal? It is a fairly new situation for me and maybe you could help me with signal levels to watch.

M11G and M33G with m.2 adapter can run a Quectel RM50x series of 5G cards.
Signal is depend from antenna you use, and how you connect the antennas in order.

To watch a signals I recommend script from https://confusedbird.com/thread-123.html called: MIMO Layer Signal Readings

Cool - thank you very much!

@Dude2048
I use this script to choose LTE devices automatically (attachment). This chooses the device with LTE connected over the other which has a lower speed band. The route priority is defined through distance value 130 and 140. Just put these scripts in the scheduler and set an interval of your liking.

Sorry - I forgot the parts, where the variables are declared. Now they're attached, too.

Hi,
Does anybody tried to put Quectel RM500Q-AE inside in RBLHGGR&R11e-LTE6 ?
Will it fit ?

I apologize for my sheer ignorance, but have you used this combination yourself?

Finally I managed to acheive an RBM33G, a Quectel RM502Q-AE 5G card and the appropriate pigtails (first I thought the connectors were u.fl but they are w.fl), but I'm unable to fit the 5G card in the M.2 slot.
AFAIK both RBM33G and the RM502Q-AE are specified to be M key M.2, but the smallest part of the contact edge of the card won't fit in the socket because this part of the socket is too narrow (the largest appears to do).
Apart from that, even if it did fit, the body of the card is too wide to fit besides the USB socket on the RB.....

Are there more variants of M.2? Or will I have to get some MiniPCI-E to M.2 adapter to use the RM502Q-AE with Mikrotik?

Anyone to shed some light on this?

JimKusz · Tue May 10, 2022 8:40 pm

You will definitely need to use a PCIe to M.2 B-Key adapter. Cell modems are all B key, M-key is only useful for storage as far as I know.

Can you provide info on your pigtails for the cell antennas?

I'm trying to get The RM500Q-GL working in an RB of some sort (wanted to use a wAP-G, but there isn't enough physical space for the length of the card, especially after the PCIe to M.2 adapter). I purchased a LtAP to try and see if it would fit and work; should show up tomorrow. Still don't have antenna connectors/pigtails/adapters for it, as it uses the smaller connector than the 4G-LTE standard Microtik designed around.

Apart from using M.2 SSDs in the RBM33G (and in PCs) I'm rather new to the M.2 word and the various standards, and also the relation to PCI-E.
Ok, then I'll get hold on such an adapter.

Can you point me towards one?
Will for instance this one do the trick?: https://www.ebay.com/itm/143003158060

I ordered these pigtails: https://www.ebay.com/itm/184297288505
Like you, from the start I did not pay attention to pigtails as I wrongly assumed the connectors were u.fl..
The world of RF connectors is not easy to get an overview of, as there are numerous new variants with slightly different dimensions. A few hours of googling learnt me that the right connector for the card comes under different names: Hirose W. FL, Amphenol AMMC and MHF4.

LtAP is a nice device with lots of possibilities, hope you get it running.
I'm going for RBM33G with aluminum (RB433-style) casing.

Hello!

I am planning to switch from LTE to 5G.
Right now i got a RBM33G with a USB3 Adapter and a Sierra EM7565 LTE modem on it - all together with a XPOL-2-5G 2x2 Mimo Antenna.

I read in your posts about the Quectel RM500Q-AE working on the RBM33G and started to plan to buy this Modem as it is available here in Austria.

Question - can i still use the USB3 Adapter with the new modem or does it have to be a m2 adapter?
If so - can you suggest one working?

thx a lot!!

I'm trying to navigate in the world of NGFF, M.2 and MiniPCIe, and according to JimKusz here these cards are B key M.2 as I suppose the Sierra Card is too.
Therefore there should be nothing keeping you from using the USB2 adapter for the Quectel card as well.
However, to me an adapter from MiniPCI-E to M.2 B key sounds like a more "native" solution, instead of going via USB.
Some years ago I tested a few USB 3G cards on Routerboards and my experience was frequent "freezes" needing an USB reset.
BTW, Same thing I saw with Sierra MiniPCI-E cards, and I did not see stability for months before the Mikrotik R11e LTE cards.
But of course, I might not have the full picture.

So if availabe, MiniPCI-e to M.2 is my bet.

That adapter should work. Not sure about the height...it appears the RM500Q module uses a non-standard height, and my adapter didn't have a screw hole at the right setting. For testing, I'm just pinning it down; the case should hold it in place when I put it together if I don't replace the adapter first...

I just got all the parts in and am trying to get mine working now. I had the LTE interface up briefly, but the quickset wouldn't give me LTE options, so I factory reset, and ever since, I get "SIM not present" even though I never touched anything with hardware. Working through that now.

In order to use the RM500Q series, you do need to be running RouterOS 7.x.

The interesting things I've learned about the M.2 (and mPCIe) is that the slots present multiple interfaces. For the B-key M.2 (like all modems), there is an actual pci express x1 slot AND USB (1/2/3 -- possibly on different pins, haven't dug into that enough). I *think* the card is presenting itself as a USB device even when in the mPCIe slot and M.2 Key B to mPCIe adapter, so it should be fine to use a USB adapter. I'd pay attention to the USB speed of the ports and port mappings, though...each RouterBoard is a bit different. I'm working with the LtAP, and it has 2 mPCIe slots on it. The bottom slot has a dedicated USB3 and an mPCIe interface connected to it, but the top slot has ONLY a USB 2.x slot, which is SHARED with the external USB port. If you want to use the external USB port, you'll need to run a ROS command to switch the USB to that interface (and disable the top mPCIe slot). Also, the external USB port on this model is only usb 2.x; not sure if 5G speeds might exceed that...The bottom slot has USB 3.x.

So...Bottom line, study the hardware for the RB you plan to use to ensure the interfaces are available and learn what commands you might have to run to switch it to the port you intend to use. If it were me, I'd go the internal route (mPCIe to M.2 key B adapter), although I'm also learning that clearances can be a pain...

Looks like I am not the only one that wants to use the RBM33G with a RM502Q-AE. I am going to be installing it in a 4xmimo outdoor enclosure. I plan to use the USB3 on the back of the M33G with a M.2 key B to USB3 adapter. I currently have the adapter hooked up to another non Mikrotik router to host the RM502Q-AE. Now just waiting on my RBM33G to be delivered and it seems to have been lost in the world of our postal system. Another thing that anyone using the RM50x series modems is that they are power hungry radios and the USB3 port of the RBM33G does not supply enough power to operate them. So the usb adapter I am using adds additional power to the RM502Q-AE.

SiB · Wed May 18, 2022 4:06 pm

m.2 key B modules use the smaller connectors MHF4 and proper pigtail must be used.
M33G on mPCIe slots have limit of 480Mbps bcs this is USB2.0 bus.
M33G on USB port can use USB3.0 but adapter must support USB3.0 too.
Sometimes we receive limit of USB EndPoints when we try use two lte modules and only one can be active.

I hope that MikroTik create a new M11G and M33G with m.2 slot for new 5G modems, this will be super. We have now 2x Chateau and one LHGGM who use m.2 slot.

I hope they will also! On some of their newest boards there is provisions for m.2. So they definitely have something in mind there. Also their road map indicates that there will be a LHG 5G. I'm hoping that has a m.2 slot in it.

Finally I got all hardware puzzled together and managed to fire up my RBM33G with the Quectel RM502Q-EA in an M.2 B Key to MiniPCI-e adapter.

When dealing with 2.4 and 5GHz Wifi I never leave an antenna connector open when powering up, just to not risk damage to the RF module.

But what about 4G and 5G cards, are they the same or can I leave some of them open without damaging?
Now I have one dualpol antenna on ANT0/ANT2 and another on ANT2/ANT3. Not too impressing perfomance but that can maybe be attributed to the antenna diagrams.

I can see from HW design manual that ANT1 and ANT2 supports lowband. Can I just use these for 2x2 MIMO (to get hold on n28 700MHz) and leave ANT0 and ANT3 open?
What do you guys do wrt antenna connections?

Hi,
Does anybody tried to put Quectel RM500Q-AE inside in RBLHGGR&R11e-LTE6 ?
Will it fit ?

Hello @connecting - or another member.

Did you find the answer to this question?

Will the RM502Q-AE fit inside an LHG R antenna - with the appropriate M.2 MiniPCIe adapter?

I have an LHGR which I realise is only 10/100 Ethernet, has the wrong pigtails but in which I wish to use a Quectel RM502Q-AE modem for the CA band possibilities and antenna gain.

I currently have the RM502Q-AE with the MiniPCIe adapter in an RBM33G all inside a Poynting 4x4 MIMO (+ 2x2 WiFi) antenna enclosure which is very well engineered but doesn’t have the antenna gain of the LHGR.

I believe the pigtails will need to be U.FL to MHF4 on the modem.

Any & all responses appreciated, thank you.

cadillackid · Thu Jul 06, 2023 5:40 pm

I am also interested in which RB can take a 5G card and fit in the enclosure..
I have an LTAP mini that with the latest 7.10 firmware and an PCIE to M.2 adapter im able to get my Quectel RM520N working in MBIM mode and I get good speed from it..

however the issue is the card does not fit properly in the adapter as its too long.. and with a heat sink is then too tall to comfortably fit as well..

I tried to run it externally in its own enclosure and connected to the micro USB port of the LTAP mini but doesnt even get seen... on a Hap AC2 it gets seen but with in USB mode I cant run MBIM.. I have to run it as ECM and the MT software seems to have trouble establishing the connection...

id really like to find something that would natively fit and take this module as it really works good and fast when its up and running.. but obviously I cant install klougey systems on customer's site.. it has to be clean..

the LTAP mini is a good solution for 4G LTE like my Telit LM960 or Quectel EM12's... but I want to take advantage of the 5G bands where I can...

-Quectel RM502Q-AE M.2 card
-4x MHF4 (?) to RP-SMA pigtails (very tiny little brother of u.fl.)
-4x RP-SMA "blade" antennas
-Oldschool RB433 metal case

BTW Normis, when will Mikrotik R11E-5G cards appear?
I guess you plan to roll out 5G versions of all your "LTEx kit" devices?

I do not have photo, and still using LM960, but same solution will use for 5G when time comes.
PCIE riser with flexible band. Works stable. My case is located at hot place under roof, so cooling modem is essential. Even with small radiator LM960 was getting too hot summertime, getting close to 80C. So I used metal case, modem touching it. No mi=ore issue with temperature.

Since 5G modem MUST be connected to 33G thru some kind of m.2 pcie adapter, I will use same approach.

Of course I would prefer to spend some money on "RBM44G" with two M.2 ports with USB3.0 lines on it.

____________________
Here is the solution. And this will be revolutionary in future of this T99W175 x55 Snapdragon model.
1st thing what needs to be done is to solder 2 back pins (better option is to use 1-10 kOhm resistor) see picture
2nd this is to isolate pin3 (I taped with clear tape but there are many better options lol)
And dont forget to switch to AT^CUSTOMER=0 (CUSTOMER=1 also has same vid/pid)before you attach to mikrotik. Otherwise it will not recognise different vid/pid
AT-Chat terminal is stable on 7.15 RC2 routerOS.

And use m2 to minipcie adapter (I got the cheapest one on ebay 7$)
I am not regularly checking mikrotik forum due to my busy family life, but sometimes it is helpfull to share information and check for any other updates. On the screen you will see RMB11G but it also work with any other mikrotik models, I have plenty of them different

Best speed that I got so far it war around 300 MB/sec due to lack of the 5G signal. It was only 1 band (n41) 100mhz wide.
Closer to the tower I got around 700 MB/sec
Good luck mate!

my situation is not so on topic, but i'm using a rm520n-glaa with waveshare adapter m.2/ethernet in a hap ax3 with usb3 cable.
It was very simple to setup, the worst think was the ipex connections....why so small????
I'm planning to use it with ethernet link, because the hap ax3 usb3 port works in 2.1....the same cable/adpter in a pc works in usb3.1.
Rural place i'm using hapax3 has no 5g (only lte) so even usb2 is good...ethernet in future will be better.
Another strange behaviour is about at-chat command, some AT commands receive ok from putty->serial, but from winbox terminal using at-chat syntax same command receive error

None that I know. Best I've found in miniPCIe is CAT18. If you care more about the 5G bands, than the speed, Fibocom appears to make a miniPCIe "5G RedCap" modem - but those have a way lower speed than a "real" CAT18 LTE modem & cannot say whether they even work (but come in miniPCIe and 5G bands):
https://www.fibocom.com/en/products/5GR ... iPCIe.html

FWIW, any third-party modem requires some tinkering, since RouterOS's LTE modem firmware upgrade is limited to the modems they ship. And then there is whole connector business...sometime the connectors are MHF4 not U.FL.

You have the Chateau if you're in Europe. Nothing outdoor. Well other than shoving a Chateau 5G in outdoor box.

pe1chl · Fri Jun 28, 2024 9:44 am

It seems that Teltonika is the MikroTik of 5G products... it offers the TRB500 which is just what I need.
The only thing holding me back is that it will be another software environment to learn, face issues and getting them resolved, etc.
But probably there will not be much to configure, I only want to connect it to an ethernet port on the RB5009 and provide internet connectivity.
(hopefully without adding another level of NAT or routing, i.e. as transparent as possible)

I know that MikroTik would be able to offer a similar device, but of course one can only do so many things at a time.

question: your M.2 B Key to MiniPCI-e adapter ... is it with or without a soldered SIM-card-holder ?

I've ordered an adapter with SIM-card-holder ( why not have a ball plus ... was the thinking ] ... and I can see my modem ... but I get a ' pin status: "ERROR" ' all the time

tried to put the SIM-card in the adapter-SIM-holder and also in the rbm33g-SIM-holder ... always ERROR ... both winbox and usb-serial-emulation with AT+CPIN? ... ERROR
.
SIM+PIN works flawless in another router ... and the m.2 modem worked with SIM+PIN in a windows-laptop ( with "native"-m.2-slot )

maybe there's an AT-command to choose the right SIM-slot if two slots are present ... ... maybe ... "have a ball plus" ... was the wrong thinking ?!

I'm not the expert on the M.2 adapters since that add another dimension of complexity with third-party modem. i.e. The M.2 KeyB adapters are not all the same, so how the SIM/USB lines are wired (and/or DIP/etc switch on the adapter) may effect how SIM card is routed... so might want to look at any docs that the adapter has on how SIM card lines are wired to the module.

Similarly, I'm not an expert on Quectel modems either. But the high end one do support multiple SIM slots, auto-detection, etc. You can set AT command to read what the modem thinks is going on by using "/interface/lte/at-chat lte1 input=" with some of the following:
AT+QUIMSLOT=?
AT+QUIMSLOT?
AT+QSIMDET=?
AT+QSIMDET?
AT+QSIMSTAT?
AT+QSIMSTAT=?

See https://forums.quectel.com/uploads/shor ... shlXjm.pdf for what those do.

If the M.2 adapter has SIM slots I'd imagine that's what will be used, NOT the internal one on Routerboard (but could be wrong, since it would depend on how the adapter is designed).

That Intel/Fibocom L860-GL16 modem seems like a PITA in a quick google. In theory, it should work since it is MBIM. It be an LTE interface since it's MBIM, not a ppp-client (although in theory that could work but even more complex

If that's not working, one thing to try is to force RouterOS into MBIM mode:

/interface/lte/settings/set mode=mbim

I'm not sure why you're messing with PPP interface. But the alternative mode above is "serial" that MAY expose all ports, but serial has a limited speed & that modem should be detected as MBIM to have full support in RouterOS so I don't recommend putting it into mode=serial.

That being said... I do suspect you'll have better luck with a Quectel EC21, since those are on Mikrotik's list of supported modem (and they use Quectel modems in some of their models):
https://help.mikrotik.com/docs/display/ROS/Peripherals

floaty · Tue Jul 16, 2024 9:16 pm

problem was and is ... mbim-mode is a V7 feature ( as far as I've understand ) and theres no lte-interface coming up in V7 and no port to communicate and configure the 'thing'
... so I started with V6.49.X
... and while I said "enough" with tinkering ... I've also reminded: mama said "do not give up early" : )

wanna say: "David Balfour" never came up speaking PCIE ( he did not even in a linux-system in it's native HP-notebook ... maybe the pcie-lanes in this notebooks-m.2 slot are not connected ... and only are usb ? )
... and more likely it is a factory-default-configuration related 'thing' in the modem too ... ¯\_(ツ)_/¯

... ! maybe ! ... after ... switching to PCIE ... and MBIM ... and saving to the NVRAM of the modem ?
... it will proudly pop-up as a G16-LTE device in V7 ? ¯\_(ツ)_/¯ ... with 1.2 GB capability ... instead of USB2-Speed ?

I'm looking for a 5G "client" device to add 5G (at high speed) at a location where VDSL is not fast enough.
I'm hoping for a 5G version of one of the known LTE devices (wAP, SXT etc), if not I likely go for a competitor like Teltonika.
You have the Chateau if you're in Europe. Nothing outdoor. Well other than shoving a Chateau 5G in outdoor box.

Well I went for the Teltonika TRB500 connected to a RB5009 router, with a UBNT access point.
It would have been an option (much cheaper) to use a Chateau 5G AX but the supplier did not have it in stock, and also it will be better to have the 5G separate and connected via ethernet so I can locate it at an optimal spot.
The TRB500 offers a "Passthrough" option where it hands out the 5G IP address directly to the client connected to ethernet via DHCP with a short lease time, so in actual operation it is "invisible" (no extra NAT).
It isn't outdoor, I will put it inside in front of a window.
Unfortunately the TRB500 does not support PoE so I have an additional box to separate power out of the PoE.

Messy, but it works well. And it works today, which is what I needed.

I've used Teltonika too with success as front device on construction sites and it was placed inside metal office-containers that was adding additional problems but it worked.

field notice ...
.
the working quectel ec21 in V7.15.2 ... brought a collateral ... the fibocom L860 is now working too in V7.15.2 ( no ... not through a brilliant engineering task ... plain fluke )
.
I unpowered the board ... switched the modems ... and rebooted with the config of the quectel and the fibocom inserted ...
... and was wondering ... why is my usb-serial-line still there ... ( little winbox screen-refresh hangover !? ) ... nah ... instead of the 4 channels from quectel ... there are only 3 channels ... like in fibocom
.
turns out the following setting is needed ... or the usb-serial-lines are not coming up in V7.X :

[admin@rb33g] > interface/lte/settings/print 
           mode: serial
  firmware-path: 
[admin@rb33g] >

.
seems the modem switches off the usb-interface if there's no ... "activity" ... within a certain amount of time after powering up ... this seems to be no issue in 6.49.X but in 7.X ... the fibocom switches off , if not the beforementioned setting is in place ... kinda odd ... but ...
.
the manual says after switching off usb, the modem is falling back to pcie ... : \ ... would be happy if
.
but so far: working fibocom L860 in ROS 7.15.2 ... ppp interface mode ... usb limitations ... but ... working

In general, if you're trying a new modem on V7, if it supports MBIM you want to use that. Now sometimes mode=serial might be needed to access /system/serial-terminal to enter some AT command (which vary by modem for stuff like switching modes etc) - for example on Quectel the MBIM AT commands. But if you can get a modem to work in Windows, including any firmware updates to modem while under windows that may be easier than deducing the right AT commands on the Mikrotik.... you'd really have a better shot of random modems working by making sure it works in windows BEFORE trying the Mikrotik.

The L860 is a Cat16 modem and support MBIM, so serial is FAR from ideal way of getting it working. PPP is limited to 25-35Mb/s, while most modern LTE/5G networks are 100Mb/s+, so you're giving up potential speed by using mode=serial. To get those speeds, the modem needs to work as an LTE interface.

if it supports MBIM you want to use that

.
I totally aggree. Problem: without a working reference system it's very hard to find out whats going wrong.
.
The windows system (from the originating HP-Laptop) lists the modem as USB-device too ... even all the GIT stuff and working linux-configs for the 7560 are related to USB
.

PPP is limited to 25-35Mb/s

... I already got 95Mbit/s with the ppp-config ot of the device, so I guess 480Mbit/s from the USB-2.0-Interface is the limit ( all antennas connected and good will from the big brother in the tower ).
Maybe the MBIM and PCIE-Interface problem is firmware related ? ... just the wrong version loaded ?
The manual says ( somewhat hazy ) that configuring the management and data-interface is only possible from already working management channel on the same bus ( so switching via USB-management-channel to PCIE-data-lane ... seems to be ... not possible !?)
.
in the peripheral sections of MT-docs ... I read of supported PCIE-connector modems ... but the PCIE-connector (like the mechanical m.2b-connector) supports PCIE, USB2, USB3 and SATA
... I (personally) heaven't seen a LTE/G5-device in ROS ... as a PCIE-bus connected interface ( did someone ? )
.
the ATL LTE18 devive ... which has a M.2B slot ... uses USB3.0 not PCIE ( regarding the block diagramm ) ... LHG LTE18 ... same board, other antenna-design ( the used datacom-protocol is not mentioned in the block diagramm )
.
[https://github.com/xmm7360/xmm7360-pci ... DEVICES.md
.
there is a working pcie-driver for the 7360-device ... but I do not own such a device ... nor one of the boards listed as supported.

this is a very interesting topic, but i did to myself a question before buy an adapter for rm520ngl, usb 3 or mpcie???
why so many users use m2 to mpcie rather than usb 3?
i'm using m2 to eth/usb on ax3

shavenne · Thu Aug 08, 2024 11:44 am

I have a RBM11G with RM520N-GL on a MiniPCIe to M.2 adapter.
I also modified a LHG LTE18 and inserted a RM520N-GL.
Also tried it with an M.2 to USB adapter attached to a HEX S.
All are working fine.

On the LHG you may need a thicker thermal pad btw. The EG18-EA is a pcb on a pcb so it's thicker than a standard RM520N-GL. Also the antenna connectors are different so you'll need adapters from IPEX/U.FL to IPEX4.

.
I ...
( personally ... and I'm not a user ... I'm just hobby tinkerer ... LTE/G5 -wise )
think, because the modems supporting USB3 are not that common yet ...
.
beasts like Intel-based Fibocom 7560 promise cat16 speeds, but only if you can manage to set up a PCIe-datalink between board and modem-hardware, USB3 is only listed as future-firmware option
.
IMHO ... if you need your LTE-sytems for production or even permanent home-using ... do net mess around and purchase the MT-Supported options ...
.
if you need a new ... and quizzing hobby ... ... why not have both ... ?
.
... and ... if the Big-Brother in the tower ... is not YOUR REAL brother ... you can have two cat6 LTE routers ... and end up with ~100MBit/s download *) anyway

floaty · Thu Aug 15, 2024 12:40 am

so
.
after tinkering for while ... that much is to recap:
rbm33g ... is a real nice board ... period
.
ordered it to test the ip passtrough feature for a redundant firewall-cluster with sd-wan capabilities ( so I needed more then one gig-ether-interfaces and wanted the option to use external antennas )
.
used the original cat6 mini-PCI-modem from a stock LtAP to do so ... stability and handling ... flawless.
.
while owning the hardware ( ... and not managing a home-aquarium) ... it's obvious to do some tests on the side:
.
had some intel-based fibocom and quectel modem devices avail ... the board rbm33g is also well supported from more liberately accessible operating systems ... so I did my part ...
what I have learned from:
.
- if ROS is the choice for your LTE-access ... use a MT-board with a fully supported modem ... no PPP ... no shenanigans ... ... only a fully supported LTE-interface ... is the real McCoy
- do NOT use modem-hardware Intel is involved with ... it's unstable ... it's poorly documented ... it brings unreliable results ( tested on different boards, with different OS's, with XMM-driver stuff and ppp standalone )
- try to find a model, that (mostly) matches yor needs ( this is valid for other vendors too) ... customizing ... especially antenna related, is long term learning and whining stuff
.
... most important ... as always ... free line of sight ... for you all
.

i'm still using a 433ah, and last year a 493 passed away... they are great piece of hardware, well structured in a good routeros.
in any case mikrotik routerboard and routeros, gives so many possibilities to satisfy every necessitiies so please mikrotik more m.2 ports with full speed bus.

pe1chl · Thu Aug 15, 2024 6:00 pm

I would hope that MikroTik some time releases a semi-outdoor device that provides 5G connection as delivered...
(i.e. without having to find modems and adapters etc to build something)
There are already some 4G devices like that.

hello everyone,
i'm having lte down link with error 19, at least once or more per day.
lte mbim: error: wdm send failed: 19
hardware is hap ax3->usb3cable->m.2/eth/usb adapter with rm520ngl.
I was using m.2 adapter without power supply, now since this morning i'm using power supply just to check.
Bts is 4x4 mimo in lte e 2x2 nsa 5g dss, so i suppose usb power is enough.
signal are good, rsrp -70db sinr 20-25db, bts is in front of me, 1/1,5 km far, so i'm using rabbit antenna came with adapter.
Firmware was upgraded, but problem started before firmware upgrade from R01..204 to V0108_01.205.01.205 (so last one) but problem still persist.
I tried to switch lte modem from auto to mbim, with same results.
what can i check?
i will appreciate every suggestions

Alessandr0 · Sat Jan 11, 2025 10:29 am

On the screen you will see RMB11G but it also work with any other mikrotik models, I have plenty of them different
Best speed that I got so far it war around 300 MB/sec due to lack of the 5G signal. It was only 1 band (n41) 100mhz wide.
Closer to the tower I got around 700 MB/sec

It's not possible to reach 700Mbit/s with the USB2.0 modifications made by you on the T99W175. The usb2 limit allows realistically to reach ≈ 380Mbit/s

pidro · Mon Jan 13, 2025 9:45 am

yoyo! Here from 2024.
I was able to get RBM33G work with T99W175 (aka DW5930e) 5G modem works via usb port on my Mikrotik.
Feel free to ask questions. It was a bit of work done but it is working now. The only thing is that there is no AT commands supported yet.
Yahoo

Hi,

Which T99W175 version you have? T99W175.33 or T99W175.36 etc... Also what is the DP/N or can you send a full photo? My final question there is no FCC lock on it?

Thanks!
