Built a local RAG system for 5G network fault diagnosis
Posted by Delicious_Garden5795@reddit | LocalLLaMA | View on Reddit | 6 comments
Stack: Llama 3.2 3B (Ollama) + BGE-M3 + ChromaDB + LlamaIndex. Runs fully local on 16GB RAM.
Ask it why a cell is dropping throughput — it retrieves real KPI logs and incident reports, returns a cited root cause diagnosis.
Data: 188k rows of real 5G operator traces with injected fault labels.
One gotcha: Llama 3.1 8B OOMs when BGE-M3 is also loaded. 3B works fine.

isnt Llama 3.2 is a bit too old? Perhaps you can try Qwen 3.5 or Gemma 4.

maybe i could test it too to see if its more efficient

Gemma 4 reasons decent, since your project needs stability and consistency, Gemma may be a better choice. If Gemma 4 performs bad, check out Qwen 3.5 series.
