How to cetifiacte 5G Femto RF by Spectrum Analyzer？

1. skip AMF to make cell up?

1.1 Use SecureCRT or MobaXterm to login gNB.

#ssh root@192.168.5.100

user：root   password：Sg@ran26

1.2 Run below commands to skip AMF.

#odi -n cpgnbapp set-amf-ready

1.3 Confirm cell status

Make sure the OpState is “connected”

2. replace RF config files?

2.1 Modify center frequency before upload  

2.1.1 Select correct bandwidth and modulation mode

Below select 60Mhz bandwidth and 256QAM modulation as an example:

2.1.2 Modify the center frequency in the signal source file and save

Open file “BS_cell_parameters” and modify “downlinkFrequency”,”rfFrequencyDl” and “uplinkFrequency”,”rfFrequencyUl” to target frequency. Then save.

2.2 use tool: WINSCP to login in eNB

Protocol：SCP

IP:192.168.5.100

user：root

password：Sg@ran26

2.3 Upload Signal source files for replacement

Upload the 4files(BS_cell_parameters,BS_prach_schedule,BS_rf_parameters,BS_user_parameters) from local path to eNodeB path: /usr/local/bin/   

and replace.  

3 Enter factory mode

3.1 Use SecureCRT or MobaXterm

ssh root@192.168.5.100

user：root   password：Sg@ran26

3.2 Enter Factory mode and reboot.

Run commands to enter factory mode and reboot eNodeB. (Note: Can’t login web after enter factory mode)

#fw_setenv boot_mode factory_mode

#reboot

4. Run commands to output RF signal

SSH to login eNodeB again and run below commands one by one:

#fsm_reset -r 3 

#qrtr-ns

#sleep 2

#fsmMonitor &

#sleep 15

#tfcsSvc & 

#syncMgr --primary-source=FREE_RUNNING --sync-mode=TIME &

#sleep 5

Until it prints: sahara protocol completed

Then enter path: /usr/local/bin/, and run command ./mac-e to output the frequency signal in spectrum analyzer:

#cd /usr/local/bin

/usr/local/bin# ./mac-e

Check the status in spectrum analyzer:

For example:

5. Exit factory mode:

Run command to exit factory mode and reboot, (Note: web login is available after exit factory mode)

#fw_setenv boot_mode normal_mode

#reboot

6. Repeat step 2~4 for different bandwidth, Frequency and Modulation test;
