Purpose
This document describes the procedure for integration of eNodeB based Dual 20. The procedure is intended to start from the point where the eNodeB is powered up for the first time, to integration the basic software es from factory to the agreed software level (L11B), to install the needed capacity and feature license key file, and to use scripts to configure the eNodeB according to work Plan. The same procedure can also be used for the integration of the Field Trial sites.
Overview of the eNodeB
ENodeB: RBS ( – Band40, 5/10/15MHz, 1x DUL, 1 x RRU(2Tx))
Software: L11B
Below is an overview of the eNodeB product “RBS 6601”. More information and detail about the HW can be obtained from the CPI “Generic Hardware RBS 6601”.
The figure below is an overview of the RBS6601 product:
The next figure shows the DUL board used in the RBS 6601:
Digital Unit LTE (DUL)
Provides switching, traffic management, timing, baseband processing and the radio interface to RU/RRU. The baseband capacity is pooled to support multiple sectors. Up to four DULs can be installed in a RBS.
