Please share your experience with tethered cellular

We've recently added a new docs page to include more information on connecting HoloLens to cellular networks. You can find it at https://aka.ms/HL5G. While hotspot / WiFi is sufficient for most use c...

Has anyone tried the Huawei E3372 (or E3372h) 4G LTE USB Modem over USB-C?  

 

The Windows 10 Desktop identifies it as RNDIS device but when connected to the HL2, it does not work out-of-the-box.

    We tested the Huawei E3372h-320 on HL2 and it did not work - even though a Win10 desktop recognizes it as RNDIS device and it works without driver installation.

    Maybe it has to be configured somehow that it works on HL2?

      retosan Unfortunately all RNDIS devices aren't created equal. Sometimes additional steps are necessary. We recommend using WiFi HotSpot as this works just fine for virtually all use cases. The only time when tethering really helps is in extreme low-latency scenarios like Azure Remote Rendierng.

      If you can't use HotSpot, devices that appear to the HoloLens as a USB-C Ethernet adapter work best. If it's possible, please try one of those or try a different RNDIS device.

      Lastly, if you need to use this exact RNDIS device, and if not being able to use this exact RNDIS device is blocking a large deployment of HoloLens 2, please let me know. I can't promise anything, but if we're talking about a large scale rollout we can investigate what might be needed to support that specific  RNDIS device.
