All of us, at some point, would have got a doubt about AC & DC. To put it in simple words, Alternating current (AC) is defined as the flow of charges that change direction periodically, and Direct current (DC) has a unidirectional flow of charges and remains the same as long as terminals connected are not changed.
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
