FAQ
Q1: What is the main application of Ericsson Radio 4418 B40T KRC 161 706/1?
A: It is a Band40 TDD outdoor macro RRU for 4G LTE network coverage and capacity boost, and hardware-ready for 5G NR software upgrade. Typical deployments are dense city sites, commercial hotspots and suburban macro cell towers.
Q2: What fronthaul interface does KRC 161 706/1 use to connect baseband?
A: It uses CPRI over SFP+ optical modules to link with Ericsson baseband units. It supports 10.1G CPRI rate for high-capacity front-haul transmission.
Q3: Is this RRU fanless? What is its protection grade?
A: Yes, passive cooling without fan. IP65 rated, fully protected against dust ingress and water jet, suitable for long-term outdoor installation.
Q4: What is the difference between new original and refurbished KRC 161 706/1?
A: New original unit comes with factory warranty and zero operating hours. Refurbished units are decommissioned radios, fully inspected, RF tested and calibrated. Refurbished versions help operators save CAPEX for spare inventory and network expansion.
Q5: What pre-installation checks should be done before deploying this RRU?
A: 1. Confirm compatibility with your Ericsson ERS baseband node and software version. 2. Inspect mechanical housing, connectors and cables for physical damage. 3. Run power-on test, CPRI optical link test, RF transmit/receive test and temperature monitoring. We complete all these tests before delivery.
