Request for Guidance on Accessing Cellular RF Measurements on iOS

Hello ,

We are developing an enterprise iOS application for cellular network benchmarking, performance validation, and analytics.

We have reviewed the publicly available iOS APIs, including CoreTelephony, and have not identified a public API that provides access to the following cellular RF/network measurements:

• ARFCN / EARFCN / NRARFCN
• Band
• Bandwidth (BW)
• Cell ID
• PCI (Physical Cell Identity)
• CQI (Channel Quality Indicator)
• RSRP (Reference Signal Received Power)
• RSRQ (Reference Signal Received Quality)
• SINR / SNR
• RSSI
• TAC (Tracking Area Code)
• TA (Timing Advance)

Could Apple please clarify whether any of the above measurements can be accessed through an officially supported mechanism, including but not limited to:

• Public iOS frameworks or APIs
• Special entitlements
• Managed or supervised-device capabilities
• Enterprise-specific capabilities
• Carrier-partner programs or integrations
• Apple-approved diagnostic or measurement frameworks
• Other approved mechanisms or programs

We are not seeking to use private APIs, reverse-engineering techniques, or unsupported mechanisms. Our goal is to understand whether Apple provides any legitimate and supported way for an enterprise application to obtain these measurements on iOS devices.

If access to any subset of these metrics is supported, could you please point us to the relevant documentation, framework, entitlement, carrier program, or enrollment process?

Our use case is limited to cellular network benchmarking, performance validation, and network analytics on iOS devices.

Thank you for your guidance.
