Product Introduction
Alcatel Lucent RRH1900-4X45 is a remote radio head used in wireless access systems, with references showing it as a 65 MHz RRH in the RRH 1900 family. It is an RF-side field unit, so the exact band, baseband pairing, and site configuration matter more than the name on the bezel.
This part is usually sourced for exact replacement work, not generic radio swaps. The buying decision comes down to platform match, RF band compatibility, and whether the unit has been tested for live deployment.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Sector down after swap | Wrong RRH type, band mismatch, or fiber/power issue | ✅ High | Check alarms, verify RRH model, inspect power and optical links | Confirm exact RRH1900-4X45 match first |
| No RF output | Baseband mismatch or failed radio head | ✅ High | Compare BBU settings, fiber status, and RRH alarms | Verify BBU/RRH pairing before replacing |
| Intermittent dropouts | Fiber loss, power instability, or thermal problem | ✅ High | Inspect connectors, measure supply, check cabinet temperature | Eliminate site issues before condemning RRH |
| Alarm on startup | Configuration mismatch or hardware fault | ✅ High | Read site controller logs and alarm codes | Match software and hardware revision |
| Low coverage or weak signal | Antenna, feeder, or RF path issue | ✅ Medium | Swap feeder path and compare signal levels | Check passive RF path before replacing RRH |
| Unit powers but no service | Provisioning problem or wrong sector mapping | ❌ Low | Review network provisioning and sector assignment | Verify configuration before hardware replacement |

Frequently Asked Questions
Q: What is the Alcatel Lucent RRH1900-4X45?
A: It is a remote radio head used in wireless access systems. The part is associated with the RRH 1900 family and is listed with a 65 MHz reference.
Q: Is this a complete base station?
A: No. It is one RF-side module in the radio chain, not the whole site. You still need the correct baseband and site configuration.
Q: Why does the exact RRH model matter so much?
A: Because band support, optical interface, and baseband pairing can differ by version. A similar RRH can look right and still fail in the field.
Q: Is it usually sold new or used?
A: In the secondary market, it can be New Original, New Surplus, or Refurbished. The listing should state the condition clearly, along with test status.
Q: Can I install it without checking the BBU match?
A: I would not. The radio head has to match the installed baseband and site software, or you end up chasing alarms and rework.
Q: Why is surplus pricing lower than factory supply?
A: It usually comes from spare inventory, decommissioned networks, or brokered stock. Lower price is normal, but the tradeoff is tighter compatibility checking.
Q: What should I confirm before ordering?
A: Confirm the exact RRH1900-4X45 label, the 65 MHz reference, the associated part number 109787622, and the baseband/platform match. That prevents most bad purchases.
