Hello,
We are developing an enterprise iOS application for cellular network benchmarking, performance validation, and network analytics.
After reviewing the publicly available iOS frameworks and APIs, including CoreTelephony, we have not identified a supported public API that provides access to the following cellular RF and network measurements:
• ARFCN
• 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)
As an example, we are interested in obtaining information similar to the following:
{
"arfcn": "",
"band": "",
"bw": "",
"cellId": "",
"cqi": "",
"pci": "",
"rsrp": "",
"rsrq": "",
"sinr": "",
"rssi": "",
"ta": "",
"tac": ""
}
Could Apple please clarify whether any of these measurements are available through an officially supported mechanism, including but not limited to:
• Public iOS frameworks or APIs
• Special entitlements
• Carrier partner programs or integrations
• Apple-approved diagnostics or measurement frameworks
• Any other Apple-supported programs or access mechanisms
We are not seeking to use private APIs, reverse-engineering techniques, or unsupported approaches. Our objective is solely to determine whether Apple provides a legitimate and supported method for an application to access any of these cellular network metrics on iOS devices.
If access to any subset of these measurements is supported, we would greatly appreciate guidance regarding the relevant documentation, framework, entitlement, carrier program, or enrollment process.
Our use case is limited to:
• Cellular network benchmarking
• Performance validation and testing
• Network quality analytics
Thank you for your guidance and assistance.
