We bought a Compex WPJ 428 board + a SIMCom 8202G LTE/5GNR modem and we try to make it work on OpenWRT

WPJ428 + SIMCOM 8202G

We try to build a NR5G router with OpenWRT as our main internet access point for our home. One specificity is that we need external antenna as on the ground there is no signal at all

Our project is currently made of the following physical parts:

A custom made case that is 3D printed - Download files
A Compex WPJ428 board - wi-cat.ru
A Simcom 8202G modema - official site
Some antennas, the setup is not definitive yet
- Log-Periodic Dipole Array (LPDA) Antenna - Directional antenna LTE 800/1800/2600 MHz, MIMO, SMA - wimo - diff between yagi and lpda
- A cheap cross antenna - amazon
- Some small wifi-like antenna - wimo, similar but different

We try to document our journey here:
