Decode LTE and NR cell identifiers: ECI (eNB+Cell), NCI (gNB+Cell), Physical Cell ID (PCI → N_ID1/N_ID2), and Tracking Area Code (TAC) — accepts hex or decimal input.
Free
Decode LTE and NR cell identifiers per TS 23.003. Accepts decimal or hex (
0x…) input. Select the radio technology, then fill in whichever identifiers you have — all sections are independent.Decimal or hex (0x…). Range: 0 – 268435455.
Enter an ECI to decode eNodeB-ID and Cell-ID.
LTE: 0–503. PCI = 3×N_ID1 + N_ID2 (TS 36.211 §6.11)
Enter a PCI to decode its SSS group (N_ID1) and PSS index (N_ID2).
Decimal or hex (0x…). Shows both representations.
Enter a TAC to see its decimal and hex values with range validation.
