– C50 could represent a downlink EARFCN in the 700–800 MHz range. For example, in Band 20 (800 MHz Europe), EARFCN 6150 corresponds to 791 MHz. C50 might be a vendor-specific shorthand for the high end of a band – possibly Band 5 (850 MHz), where EARFCNs around 2450–2650 are common; C50 deviates but could be an internal hex/decimal mapping.
| Field in phone | Displayed value | Real parameter | |----------------|----------------|----------------| | RAT | 4G LTE | LTE only | | Bandwidth | 5M | 5 MHz | | Cell ID (hex) | H43 | eNodeB 0x43 (67 decimal) | | CI (E-UTRAN Cell ID) | C50 | Actually the PCI or ECI low part | | Modem Config | Mv2.227 | Firmware build |
It is highly unusual to encounter a string like in standard consumer telecom documentation. This is not a typical commercial code for a data plan, a phone model, or a signal band. Instead, the structure strongly suggests an internal engineering parameter set , likely from a base station configuration log, a field test mode screen on a smartphone, or a proprietary firmware string from a networking device (like a CPE or industrial router).
Extract the MCC/MNC from surrounding logs. Examine SIB1 (System Information Block 1) of that cell – it will reveal the real operator. Cross-reference Mv2.227 with your modem vendor’s release notes (Quectel EG25-G, for instance, uses similar versioning).
If you are troubleshooting a connection issue, check if H43 and C50 appear as source and target cells in your handover trace. If Mv2.227 is outdated relative to other cells, consider pushing a firmware update to the modem.
