Set Up Base Station Calling

  1. Plug in the SDR.
 * Connect SDR to the computer.
 * Perform Radio Checks.

lsusb
ifconfig
  1. Configure the network connection for IPv4.
 * Create a new interface netmask graphically or via CLI:

Interface#
IPV4
192.168.1.20/24
  1. Confirm the setup using:
uhd_find_devices
   Ensure the device is listed.
  1. Update the configuration:
cd /usr/src/osmo-nitb-scripts
sudo nano config.json
sudo main_uhd.py -u --sip
   * `-u` enables interactive mode.
   * `--sip` enables Asterisk support.
  1. Run the following in another terminal:
/usr/bin/osmo-trx-uhd -C /etc/osmocom/osmo-trx-uhd.cfg

Set Up Base Station OpenBTS

  1. Plug in the SDR.
 * Confirm the interface name:

lsusb
ifconfig
  1. Configure the network connection for IPv4.
 * Create a new interface netmask:

Interface#
IPV4
192.168.1.20/24
  1. Navigate to the OpenBTS directory:
cd /usr/src/OpenBTS/
  1. Register the SIM:
sudo /usr/src/OpenBTS/OpenBTS
   Connection should be quick.
