Ericsson RAN Processor 6631 KDU1370071/11
The Ericsson RAN Processor 6631 (Hardware Part Number: KDU1370071/11 or KDU 137 0071/11), often marketed as the Baseband 6631, is a high-capacity multi-standard baseband processing unit designed for both Centralized and Distributed Radio Access Network (RAN) architectures. It is a 1U-high module that supports GSM, WCDMA, LTE, and 5G New Radio (NR) simultaneously, offering the same capacity as the earlier 6630 but with enhanced flexibility for 5G NR deployments.
Technical Description for Ericsson RAN Processor 6631 KDU1370071/11
The Ericsson RAN Processor 6631 KDU1370071/11 serves as the central processing “brain” of a base station, managing traffic, switching, timing, and radio interfacing.
- Multi-Standard Versatility: It can handle up to three standards in mixed-mode operation, including LTE and NR concurrently.
- 5G Optimized: It is tailor-made for 5G Advanced and enhanced AI/ML capabilities, supporting high-speed optical interfaces for fronthaul connectivity.
- Scalability: The modular 19-inch rack design allows for simplified site architecture and hardware reuse, with software-upgradable features for future network evolutions.
