We missed you Kojro !!! Good you're back 🙂 I worked on this topic, and found many IPs pointing to "that country", among firmware signatures from US vendors.
Just for clearance: the part you examined is not the whole base station. It is just the RF Unit (RFU). The „brain“ of the basestation sits in the UMPT Board, It is connected to a UBBP Board via the Backplane of the BBU, which is connected via SFPs to the CPRI Ports of your unit.
Yes I kind of know as there was mostly signal prosessing stuff and some simple nettwork prosessing CPU's in there., and the thing I was really looking for was the power supply unit.
Some observations: a microphone acoustically coupled to your workbench is making too much noise everytime you remove a screw. A small pad of foam beneath this mic will help tone that down so it doesn't drown your lapel/lavier mic out when you are speaking while you work. An interesting bit of kit you have there. It shows just how far Chinese manufacturing has come in the last several decades while we weren't watching.
The phone was monted on a makeshift mount between a bench vise and and a hand vise. I will try to use my other camera instead, and today I am doing some tests with a gopro.
Potentially interesting but there was something wrong with the white level of the camera or HDR settings so that I could only see a whitish mass in your hands with almost no details.
Sorry for that, I explained in the video that my iphone overexposed the images. I am not sure way, but I am now using a GoPro when i film there and it sems to be much better.
