AmariSoft LTE

The image used for this experiment is 'baseline.ndz'. In this tutorial we will use nodes equipped with Netgear AC341u LTE dongles. The basestation is Amarisoft running on Bsc03out.

During a normal experiment using OMF, the following actions are scripted and automated. This is a look at the steps involved in something as simple as starting an LTE connection behind the scenes.

You will run the following commands on node7-1.grid.orbit-lab.org

After connecting to the grid console:

  1. omf load -i baseline.ndz -t node7-1.grid.orbit-lab.org
  2. omf tell -a on -t node7-1.grid.orbit-lab.org
  3. It will take roughly 60 seconds to come up.
  4. ssh root@node7-1.grid.orbit-lab.org
  5. modprobe GobiSerial
  6. modprobe GobiNet
  7. minicom -D /dev/ttyUSB1
  8. AT!ippassthrough?
  9. It should return 1

  1. If it does not, run AT!ippassthrough=1 then AT!reset

AT!entercnd="A710"

  1. You should see OK

AT!dxcfg=wwan,connect,11

  1. You should see OK then $QCRMCALL: 1, V4

at!gstatus?

  1. Will return a status like:
    at!gstatus?

    5. Exit Minicom by **PRESSING** {{{ Ctrl+A followed by x}}}, then {{{enter}}} to select ok.[[BR]]
    {{{ dhcpcd eth2 }}} followed by {{{enter}}} to get a new line. [[BR]]
    6. You should get an address in the 192.168.3.0/24 subnet. [[BR]]
     {{{ ping 192.168.3.1 }}}
    7. You have successfully communicated with the basestation. [[BR]]
    8. You can cancel the ping with {{{Ctrl+C}}} [[BR]]
    9. {{{iperf -c 192.168.3.1 }}}
      This will report your bandwidth to the basestation.[[BR]]
