Ericsson 3418

The Ericsson 3418 refers to a prominent series of 3G (W-CDMA/UMTS) radio base station components, specifically the RBS 3418 (Main Unit/Baseband Unit) and the RRU 3418 (Remote Radio Unit). Introduced around 2009–2011, this series marked a significant architectural shift in mobile infrastructure toward the distributed BBU/RRU model, which remains the industry standard today for 4G and 5G networks ScribdResearchgateInstructables.

Product Insights & Specifications

The system is designed for high-capacity W-CDMA deployments and utilizes fiber-optic "feeders" to reduce signal loss Instructables.

* System Architecture: The RBS 3418 is a 4U-high, 19-inch rack-mounted baseband unit that can support up to six RRUs (remote radio units) ScribdResearchgate.

* Frequency Bands: Available in four primary versions: 850 MHz (Band V), 1900 MHz (Band II), 2100/1700 MHz (Band IV), and 2100 MHz (Band I) ScribdInstructables.

* Power & Efficiency: While groundbreaking, these units are known for high auxiliary power consumption (cooling/signaling), often using up to 95% of peak power even under light traffic loads Researchgate.

* Maintenance Note: Maintenance typically involves fiber optic testing, as nearly 70% of system errors are traced back to contaminated or damaged fiber endfaces Instructables.

Market Trends & Availability

* Lifecycle Status: The Ericsson 3418 is now a legacy product, primarily found in the secondary and refurbished markets as global operators sunset 3G networks in favor of 5G ResearchgateVuakem.

* Sourcing & Pricing: Current availability is limited to specialized B2B telecom suppliers (e.g., TelecomEasy).

* Refurbished Units: The RBS 3418 R48-5800A (Part: BML403120/1-REF) is currently available as a refurbished item, typically requiring a custom quote rather than fixed public pricing Telecomeasy.

* Modern Alternatives: Markets have largely shifted to newer Ericsson RAN Processors (e.g., BBU 6630/6648), which offer multi-mode 4G/5G support and significantly better energy efficiency. Prices for newer refurbished 5G BBUs range from $400 to $3,000 depending on the model and capacity.
