Ericsson DUL 20 01 KDU137533/41

The Ericsson DUL 20 01 KDU137533/41 (part number KDU137533/4 KDU 137 533/4 or KDU 137 533/41) is a second-generation digital baseband unit designed specifically for LTE (Long Term Evolution) within the Ericsson RBS 6000 base station series. It handles the eNodeB functions, including baseband processing and backhaul interface management.

Description and Application for Ericsson DUL 20 01 KDU137533/41

The DUL 20 01 acts as the “brain” for LTE operations in macro base stations like the RBS 6201 and RBS 6601. Unlike the “DUS” (Digital Unit Smart) series which often supports multi-standard (GSM/LTE) operations, the DUL (Digital Unit LTE) is dedicated to LTE traffic processing.
