LTE ECI is a 28-bit identifier
A common macro eNodeB layout uses 20 bits for the eNodeB ID and 8 bits for the local cell ID. Short and long macro eNodeB formats use different bit splits, so the tool makes the node length explicit.
5G NCI is a 36-bit identifier
The NR Cell Identity combines a configurable 22-to-32-bit gNB ID with the remaining bits used for the local cell ID. The selected bit length must match the network design.
Decimal and hexadecimal are the same identifier
Hexadecimal is a compact representation of the same bits. This calculator preserves leading width in output and uses integer arithmetic for accurate 36-bit values.
Frequently asked questions
How do I get eNodeB ID from an LTE ECI?
With a 20-bit macro eNodeB layout, divide the 28-bit ECI by 256 or shift it right by 8 bits.
How do I split a 5G NCI?
Choose the gNB ID bit length used by the network. The remaining bits form the local cell ID.
Can I paste a hexadecimal Cell ID?
Yes. Select hexadecimal input and enter the value with or without the 0x prefix.
