RAN dimensioning utility for determining the required Zero Correlation Zone (Ncs) and Zadoff-Chu root sequences needed to generate 64 preambles per cell, mapped to target coverage radius.
PRACH planners derive preamble roots and Ncs from cell radius so 5G/4G random access remains detectable and collision-managed.
The planner calculates the minimum cyclic shift required to ensure preambles from distant UEs do not overlap due to propagation delay. It then derives the number of physical root sequences needed to fulfill the 64-preamble-per-cell requirement.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Compliant with 3GPP TS 38.211 and TS 36.211 standards. Essential for avoiding preamble collisions and optimizing handover performance in high-mobility or large-cell environments.

Extending rural radius without updating Ncs causes undetectable preambles at the edge—planner catches that before drive tests.
High-speed scenarios need additional Doppler considerations.
Zadoff-Chu roots, Ncs, and preamble formats based on cell radius so random access works without excessive collisions or undetectable preambles.
Larger cells need larger cyclic shifts / formats that tolerate delay. Small cells can use denser configurations.
Attach failures, RACH storms, and unexplained accessibility KPI drops—especially after introducing larger rural cells.
