Ericsson RBS 6000 architecture¶

The Ericsson RBS 6000 architecture consists of many different modules, roughly split into two parts:

• Digital Unit (baseband)
• Radio Unit (ADC/DAC/PA/Duplexer/Diversity/...)

The two units are interconnected via CPRI using SFP Transceivers (typically fiber optic based). As far as we know, for GSM the CPRI line speed is 2.5Gbps.

A single Digital Unit can drive multiple Radio Units (typically up to 6).

GSM support in RBS6xxx¶

Digital Unit¶

• DUG 10 (Digital Unit GSM) for up to 12 TRX using RUG
• DUG 20 (Digital Unit GSM) for up to 12 TRX using RUS or RRUS
• DUL 20 (Digital Unit LTE) using RUS or RRUS
• DUS 30 for up to 12 TRX using RUS or RRUS
• DUS 31 for up to 24 TRX using RUS or RRUS (12 TRX in mixed mode LTE + GSM)
• DUS 41 for up to 48 TRX using RUS or RRUS (12 TRX in mixed mode LTE + GSM)

Radio Unit¶

• RUG (Radio Unit GSM) for 2 GSM TRX
• RUS (Radio Unit SDR) for 4 GSM TRX (or 3G/4G with DUW/DUL)
• RRUS (Remote Radio Unit SDR) for 4 GSM TRX (or 3G/4G with DUW/DUL)
• Radio 22xx Remote Radio, multi-standard (2-4G + NB-IoT) and mixed-mode.
