- install open5gs https://open5gs.org/open5gs/docs/tutorial/01-your-first-lte/
- SDR: BladeRF Micro 2.0
- 4 LTE Antennas
- open5GS for core network
- Samsung galaxy j7 as UE
- Sysmocom sim card
- Quectel RM510G-QL + sysmocom for UE (26/01/24)
- for setup epc, enb: https://docs.srsran.com/projects/4g/en/latest/app_notes/source/cots_ue/source/index.html
- for add subsciber to open5gs: https://open5gs.org/open5gs/docs/tutorial/01-your-first-lte/
- for start services of open5gs: https://open5gs.org/open5gs/docs/troubleshoot/01-simple-issues/
- for doing the project: https://github.com/fllay/LTE/wiki
- for configure quectel: https://github.com/pchat-imm/quectel_rm510q_gl.git
note that current quectel that I ping can only send short traffic, worse than using mobile phone
follow link: https://github.com/Nuand/bladeRF
git clone https://github.com/Nuand/bladeRF.git
mkdir -p build
cd build
cmake [options] ../
make
sudo make install
sudo ldconfig
if you already install srsRAN_4G but haven't installed bladeRF, you will have to install from source again.
install pre-processor
sudo apt-get install build-essential cmake libfftw3-dev libmbedtls-dev libboost-program-options-dev libconfig++-dev libsctp-dev
then install srsRAN_4G (make test not really required)
git clone https://github.com/srsRAN/srsRAN_4G.git
cd srsRAN_4G
mkdir build
cd build
cmake ../

make test
sudo make install

### Add NAT Rule
$ sudo iptables -t nat -A POSTROUTING -s 10.45.0.0/16 ! -o ogstun -j MASQUERADE
configure firewall correctly
$ sudo ufw status

without the masq ue cannot access internet, also the epc screen won't show Sending EMM Information
check the mask interface using command route
