Product Overview

The Ericsson Baseband 6630 KDV127621/11 is a high-capacity baseband unit designed for Ericsson Radio System main-remote configurations.

It supports GSM, WCDMA and LTE, including mixed-mode combinations, and is designed for sites requiring high baseband capacity in a compact 1U 19-inch rack format. Ericsson technical documentation states that Baseband 6630 provides capacity and mixed-mode capability equivalent to Baseband 5216 while adding a standalone chassis, integrated cooling and 15 CPRI interfaces for direct radio connectivity.

The hardware is also described as prepared for NR (5G) and eCPRI, making it suitable for network modernization and future-oriented deployments.

Linkworld Telecom supplies Ericsson Baseband 6630 units in used or refurbished condition, depending on current stock availability.

Technical Specifications

The dimensions, weight, 15 CPRI ports, power configuration and interface layout are listed in Ericsson Baseband 6630 technical documentation.

Multi-Mode Network Support

Baseband 6630 is designed for multi-standard network deployments.

Ericsson material lists support for:

• GSM

• WCDMA

• LTE

• GSM + WCDMA

• GSM + LTE

• WCDMA + LTE

• GSM + WCDMA + LTE

This allows one baseband platform to support mixed-generation RAN environments without requiring separate hardware for each radio technology.

CPRI & Radio Connectivity

One of the main strengths of Baseband 6630 is its high radio-interface density.

It provides:

• 15 × CPRI SFP/SFP+ interfaces

• Direct connection to compatible Ericsson radio units

• Reduced need for a separate Baseband R503 expansion unit

Ericsson specifically highlights the 15 CPRI ports as a major design advantage for main-remote configurations.

Transport Interfaces

Baseband 6630 provides both optical and electrical transport connectivity:

• 2 × optical 1/10Gbps SFP/SFP+

• 2 × electrical 1Gbps RJ45

This supports flexible backhaul and transport integration in telecom base station environments.

5G & eCPRI Readiness

Baseband 6630 was originally designed around GSM, WCDMA and LTE, but Ericsson documentation states that the hardware is prepared for NR (5G) and eCPRI.

For SEO and technical accuracy, I recommend describing it as:

5G-ready / hardware prepared for NR and eCPRI

rather than claiming every Baseband 6630 configuration runs 5G NR by default. Actual 5G capability depends on software, licensing and network configuration.
