# How to Connect OAI eNB (USRP B210) with OAI UE (USRP B210) without S1 Interface
**NOTE: OAI UE is still work in progress. We plan to release a working version soon. There are folks on the mailing list who have made OAI UE work to a limited extend. Please understand that there is limited support from our team at this moment for OAI UE. **
This tutorial is intended to setup the OAI eNB and OAI UE without the S1 interface and allowed the UE to connect to eNB. You need 2 Ubuntu machine and svn version r7753 of OAI for this tutorial.
