[srsran-users] srsENB @20Mhz BW

Hello,

I have some additional information that may help point to the problem.  

If I increase the bandwidth >3Mhz, the trace of the ENB starts running with (or similar numbers to 461) this:

RF status :O=461, U:0, L=0  the UE does not see or connect to the ENB

On BW below 15Mhz there is no trace output ant the UE connects

Thank you

Philip

Hi

Thank you for the help. Because the link EPC to UE works one way (UE bladeRF) and the config files are the same on both PC's, I not sure how it can be the config, but it's a good idea to reinstall fresh so both PC's are at the same version (srsRAN)

May I ask what's the recommended version of Linux Ubuntu please? Or do I simply install the very latest.

I am really clutching at any possible outside issue of Hardware Linux version or even the FPGA versions.

Kind regards

Philip

Hi Henry,

Take a look here:

|$ grep -r -i "Software Radio Systems R" srsepc/src/main.cc: 
("mme.full_net_name",
bpo::value<string>(&full_net_name)->default_value("Software Radio Systems RAN"), "Full name of the network") |

Best regards,
Robert

I Philip,

This could be a config issue. I'd suggest to update to the latest version. If you built and installed manually (i.e. `make` and `make install`), you could just repeat that with the new version. Please back-up your config files first.
After installing the latest version, you can diff your config files with the default ones to see what has changed and then adapt the configs accordingly.

Best regards,
Robert
