# How to Connect OAI eNB with COTS UE via the OAI RRH GW (USRP-B210)

In this tutorial, we will introduce how to connect a commercial off-the-self UE (i.e. smartphone and LTE dongle) with the C-RAN version of the OAI eNB. As it is dictated by the C-RAN concept the radio front end hardware is detached from the eNB and is incorporated to a remote radio head (RRH) instead which is connected to the eNB. Within the framework of OAI this concept is realized as follows:

In this tutorial, we will describe how to connect a commercial off-the-self UE (i.e. smartphone and LTE dongle) with the C-RAN version of the OAI eNB. As it is dictated by the C-RAN concept the radio front end hardware is detached from the eNB and is incorporated to a remote radio head (RRH) instead which is connected to the eNB. Within the framework of OAI this concept is realized as follows:
|
|
|
* the OAI eNB functionality is extented so that OAI eNB is able to interface via Ethernet a RRH
|
|
|
* a new software entity is introduced, namely the OAI RRH GW which acts as an abstraction between radio front end equipment (e.g. USRPB210, BLADERF and LMSSDR) and the OAI eNB
