Ericsson Baseband 6630 — 5G Ready Multi-Standard Baseband Unit (1U / 19” / 15 × CPRI)

1. Product Overview

The Ericsson Baseband 6630 is a high-performance, multi-standard baseband unit designed for GSM, WCDMA, LTE, and Massive IoT (NB-IoT/eMTC) operation, with hardware readiness for 5G NR and eCPRI.
It belongs to the Ericsson Radio System (ERS) and RBS 6000 families, supporting macro site D-RAN/C-RAN architectures with flexible capacity and low power consumption.

2. Hardware Design and Interfaces

Parameter	Specification
Form Factor	1U height, 19-inch rack-mountable
Depth	< 352 mm
Cooling	Replaceable front fans, front-to-rear airflow
Radio Interfaces	15 × CPRI (SFP/SFP+) for Radio Interconnect
Transport Interfaces	2 × 1/10 GbE (SFP/SFP+), 2 × 1 GbE (RJ45)
External Alarms	8 × dry contact inputs
Maintenance Port	1 × Local Maintenance Terminal (LMT)
Power Supply	Dual −48 V DC inputs (2-wire or 3-wire options)

Note: Baseband 6630 provides the same 15×CPRI configuration as Baseband 6620 but offers higher throughput and 5G-ready features equivalent to Baseband 5216.

3. Performance and Power Consumption

Parameter	Specification
Supported Standards	GSM, WCDMA, LTE, NB-IoT, eMTC, and NR-ready
Architecture	D-RAN / C-RAN
Typical Power Consumption	≈ 123 W (at 25°C, typical load)
LTE / NR Capability	Multi-carrier and multi-cell operation (software-dependent)
5G NR Readiness	Hardware-prepared for eCPRI and NR baseband processing

Actual capacity (carriers, sectors, throughput) depends on software version and active licenses.

4. System Compatibility and Networking

Compatible Radios: Ericsson Radio 22xx / 44xx / 88xx series RRUs
Front-haul: Supports CPRI star, chain, or ring topologies
Transport: Ethernet/IP interfaces for transmission and management
Software Environment: Operates under Ericsson Radio System (ERS) with multi-standard concurrency
Deployment: Ideal for both indoor macro sites and centralized RAN (C-RAN) hubs

5. Mechanical and Maintenance Features

Parameter	Specification

7. Applications

Multi-RAT macro base stations — simultaneous GSM, WCDMA, LTE, and NB-IoT operation
C-RAN / D-RAN configurations — connects up to 15 RRUs for multi-sector, multi-band sites
5G Evolution — ready for NR expansion via software and eCPRI interface
Energy and space efficiency — replaces legacy multi-board setups with a compact, low-power 1U unit

8. Quality Assurance and Field Verification

Before deployment, each Baseband 6630 should undergo:

CPRI and Ethernet interface validation
Power and alarm port testing
License and software compatibility checks for LTE, NB-IoT, or NR functions
Performance verification (throughput, synchronization, timing)
