Transport engineering utility for sizing inter-node links on the X2 (eNB-eNB / eNB-gNB) and Xn (gNB-gNB) interfaces, covering handover payloads and signaling overhead.
X2/Xn transport calculators dimension control- and user-plane bandwidth for 4G/5G handovers so midhaul does not clip mobility performance.
The sizer calculates the aggregate bandwidth from concurrent handover data forwarding streams plus the background X2AP/XnAP control plane load, producing a total transport requirement with engineering margin.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Essential for inter-site link planning in LTE and 5G NR networks where high mobility (e.g., rail or highway coverage) creates frequent handovers. Oversized X2/Xn links reduce latency during handover execution.

High-speed corridor sites with large HO rates need far more X2-U than static rural sites with similar radio bandwidth.
Vendor HO algorithms change forwarding volumes.
Handover signaling and, depending on architecture, user-plane forwarding during mobility between eNB/gNB.
From handover rate, average forwarded data during HO, and control-plane message sizes—with peaks for dense urban mobility.
