This folder contains a basic shell script that allows a quick end-to-end LTE test
using srsUE, srsENB, and srsEPC. The script has minimal requirements and should
only take less then 30 seconds for each configuration. Currently the script
only allows to configure the cell bandwidth.
only allows to configure the cell bandwidth and the number of component carrier in the eNB.
The script launches all components and puts the UE into a different network namespace
in order to allow IP connectivity to srsEPC on a single machine. It therefore
requires root privelages at the moment.
It then launches, one after another, uplink and downlink ping as well as a quick UDP
downlink session. Between those experiments, the UE transits between RRC Idle and Connected
states multiple times and is either put into Connected through pending UL traffic or
pending DL traffic (using paging).

the entire time.
After the experiments are finished, all components are torn down and the log files
are analyzed.
