WPJ428 + SIMCOM 8202G
We see this project as a way to assess how well we can regain control/understanding on our NR5G/LTE routers.
And for now the answer seems to be "very little".
Our case study is a NR5G router as the main Internet access point in a place where we have no signal on our cellphones. We
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:
- Guides
- Problems we encountered
- Dimensions for the board in the datasheet are wrong
- Ethernet ports are not configured at boot
- Signal is not optimal with an antenna under the roof
- The UDP+Don't Fragment bug
- Tracking the bandwidth bottleneck
- Our modem never connects on NR5G Non StandAlone (NSA) aka E-utran New radio Dual Connectivity (EN-DC)
- Some logs/data/info about our hardware
- Misc
