[HR369]

Dear All,

I want to use a 4 G LTE modem for internet data connection along with voice phone call communication using RJ45 ethernet connection for Raspberry pi 5 SBC board, Kindly suggest any opensource modem or any evaluation board.

Even i am ready to design my own PCB design, If anyone knows schematic for the same. Kindly share for reference.

I have heard of "usrp b205mini". This is SDR transceivers that I know some designers use it as test platform for LTE...etc

You still need to get baseband to interface from SDR to ethernet.
