5G Small-Cell Handover & mmWave Blockage Simulator

Drive a phone along a street lined with 5G mmWave small cells: watch human/vehicle blockage collapse the signal, an A3-style handover algorithm hand you to the next cell, and RSRP, throughput and outage react live to cell spacing, hysteresis and time-to-trigger.

A handset drives past a row of 28 GHz mmWave small cells while pedestrians and vehicles cross the street and momentarily block the line of sight. Each cell's RSRP is computed from a real 3GPP free-space path-loss formula plus a blockage penalty, and the phone switches serving cells using the same A3-style hysteresis + time-to-trigger event real networks use — showing live RSRP, Shannon-capacity throughput, handover count and link-outage time as you tune cell density, blocker traffic and the handover parameters.

⚙ Under the hood

Drive a phone past a row of 28 GHz mmWave small cells while pedestrians and vehicles block the signal, and watch the real 3GPP A3-style handover algorithm switch cells as RSRP, throughput and outage time respond live.
