This tutorial explains how to connect 2 UEs to a eNB, with simulated RF board, on same machine.<\/p>\r\n\r\n\r\n\r\n
It reuse the other tutorials we published in a quite complex IP addresses configuration<\/p>\r\n\r\n\r\n\r\n
Do this tutorial, with the UE on same machine option.<\/p>\r\n
To install EPC, eNB, use all-in-one tuto, with latest commit in develop branch<\/p>\r\n
you should reach one UE in traffic<\/span>, all on one machine<\/strong><\/p>\r\n The UE always use the current directory files for SIM files so we make a second directory and create the files in this directory<\/p>\r\n In one more window, launch some traffic in the second UE<\/p>\r\n <\/p>\r\n\r\n\r\n","protected":false},"excerpt":{"rendered":" This tutorial explains how to connect 2 UEs to a eNB, with simulated RF board, on same machine.
