| 31 | == Generalizing |
| 32 | To run this on other machines, you will need 3 devices. |
| 33 | * One with a USRP B210 |
| 34 | * One with sufficient processing power |
| 35 | * And one to act as client. |
| 36 | |
| 37 | To run this on nodes 1-1,1-2, and 2-1 on Sandbox 1, you would need to make the following changes: |
| 38 | 1. Load the rrh image onto nodes 1-1 and 1-2. |
| 39 | 1. execute the rrh scripts on node1-1 |
| 40 | 1. on node1-2, edit the file ~/conf/enb.band25.tm1.rrh.usrpb210.conf |
| 41 | 1. change the lines {{{ENB_IPV4_ADDRESS_FOR_S1_MME}}} and {{{ ENB_IPV4_ADDRESS_FOR_S1U}}} to {{{10.11.1.2}}}, or the interface that will send traffic to the MME |
| 42 | 1. If you want to change the RRH interface or IP, you must change it in both run scripts, as well as the lines {{{local_if_name}}}, {{{remote_address}}}, and {{{local_address}}} in the eNB config. |
