RAN Inventory Modeling

I hope you are doing well. I am currently working on a telecom inventory modeling project and need some guidance.

My model structure so far is: Country → State → City → Building → Rack → Device, with both physical and logical connections.

However, I am unsure how to proceed with the following scenarios:

  1. City → Tower → [Next Step]
  2. City → pole→ [Next Step]

Could you kindly share your thoughts on what should come next in the flow for these scenarios?

I would really appreciate your help.
Best regards,
Ram Kumar
