I am working on an IoT project and trying to understand how cell identifiers are assigned on hybrid networks. Specifically, I want to know if LTE-M Cell ID and standard LTE Cell ID are identical or if they differ.

From my understanding, LTE-M (eMTC) coexists within the standard LTE spectrum and shares the same physical eNodeB and tower infrastructure.

However, I am unclear on the following:

1. Physical vs. Logical ID: Does an LTE-M device reading the cell identity (e.g., via AT commands like AT+CEREG or AT+QCELL) get the exact same global EUTRAN Cell Identifier (ECI) as a standard LTE smartphone connected to that same sector?

2. Network Mapping: If I use a third-party geolocation API (like OpenCellID or Wigle) that relies on standard LTE Cell IDs, will the Cell ID retrieved from my LTE-M module map correctly to those databases?
