[srslte-users] Connecting to the eNodeB

[Paul Sutton]

Hi Henrik,

LTE uses mutual authentication where the network authenticates the user
but the user also authenticates the network. As a result, it is not
possible to simply whitelist all users in the network - you would also
need to whitelist the network at the user.

We use both test USIM cards and programmable cards for our lab setups.
Test USIMs have fixed, known parameters and can be found from sellers on
e.g. eBay. We typically buy programmable USIMs from
http://shop.sysmocom.de/t/sim-card-related/sim-cards .

For an excellent overview of everything USIM-related, I recommend
https://www.sysmocom.de/manuals/sysmousim-manual.pdf

Best regards,
Paul
