5G Small-Cell Handover & mmWave Blockage Simulator (2D)

Top-down 2D view of a phone driving 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, shown here from directly overhead, 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 — a scrolling telemetry strip beneath the map shows 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

Watch a phone drive along a top-down street map lined with 28 GHz mmWave small cells while pedestrians and vehicles block the signal, and a live scrolling telemetry strip shows the real 3GPP A3-style handover algorithm switching cells as RSRP, throughput and outage time respond.
