Who can recommend an LTE stick which supports LTE CAT4



  • Who can recommend an LTE stick which supports LTE CAT4 and runs on Deutsche Telekom LTE frequencies?

    I know there is a list of supported / tested modems, but it seems a bit outdated and I don't think any supports LTE CAT4.

    thanks! Till



  • I know there is a list of supported / tested modems, but it seems a bit outdated and I don't think any supports LTE CAT4.

    If you still find no device such this supported by pfSense and the German Telekom you could try to find
    by side a modem that is supported by Linux and the German Telekom and then you install Linux on a
    RaspBerry PI 2.0 and put the modem in and then you could add this self made Linux based modem
    to the WAN Port of your pfSense machine!



  • What is the type GSM or CDMA and what LTE bands/frequencies?



  • Even if you could find a CAT4 modem you would be restricted to DirectIP speeds in pfSense so 150mb modem is useless in a 25mbit environment.

    Jeremy from Netgate has been hacking on QMI so there may be movement in that direction. Not an easy task for sure.

    These are 500 bucks and I don't know that they offer an 150mbit version.

    You could also consider one of your local cellular carriers" MiFi's and use USB tethering mode. Hooks to pfSense via an UE0 interface with the mifi handling the connection and dhcp…Once again are there CAT4 versions yet?

    Here in the US we have slow adoption of CAT4 as only Verizon/CDMA offering it.



  • Here is a Sierra 150mbit MiFi. I can't guarantee it will work, but there are no USB sticks or Mini PCIe modules out yet that i see.

    Another Mifi that might work…

  • Found this module, though unsupported.

  • Thanks for all the advise!
    Yes, I know I can use a mifi and I have one (well, still CAT3).
    For another location I was looking for a more all in one solution and was hoping someone has built that already.
    DT offers USB sticks themselves  and the latest CAT4 based model is built by Huawei and most probably identical to the E3372.



  • Huawei has some recent successes here with pfSense, so maybe you could get it to work. They use Qualcomm as does Sierra so that is a good thing. AT command guide in the other thread.. Good chance you would have to add-in the VID/PID at a minimum with a custom kernel build. Huawei seems to be open about thier stuff and that helps. Sierra wants passwords just to download pdf's.



  • @skywalker:

    If it's running 21.X firmware you should be able to use it in PPP mode without problems.
    With 22.X (HiLink) firmware you will get an additional NAT (as the modem will behave like a router) and probably a higher speed comparing to PPP, this is not a standard setup but you will find a recent success story here.



  • If you have one more Ethernet port, you could use one of these Zyxel devices. They can use be used in bridge mode (no double NAT):

    • LTE3301

    • LTE3311

    • LTE7410

    (I am not related to Zyxel nor do I own or use one of them. But I am interested in a future 4G backup solution and so I found them)



  • a modem that is supported by Linux and the German Telekom and then you install Linux on a
    RaspBerry PI 2.0

    I have used this approach. I have used OpenWRT for a modem OS and any simple SBC or supported old router with USB stick and OpenWRT as a WAN provider.

    I was replicating the Sierra GX440 the cheapest way possible. I used an older Atom SBC.
