3.5" Long range with cheap 4G modem | OpenIPC over 4G/LTE

Hi, I decided to revisit the old cheap Huawei E3372 4G modem as I had a bunch of them. The video is made of the DVR from ground station + cropped OSD from 30fps screen recording, sometimes they get out of sync, not sure why if its OBS fault or gstreamers where it tries to sync frames to a real clock instead of timestamps coming from the media stream itself. In the end it worked okay, if you can get it for cheap, but if you can spend 50€ for SIM7600G-H you will have better experience, less stutters and dropouts. I tested both modems with buffer test and the E3372 has a lot more latency inconsistencies. Although I just used the internal antenna of the modem. SIM7600G-H uses bands 1, 3, 7, 20, and 28, primarily relying on the long range bands 20 and 28. E3372 doesnt support 28.
