The busiest crossing on Earth. Two thousand phones step off the curb at once, and every one of them asks the network the same question: which cell do I belong to now?
01 · The densest grid in the world
Dozens of small cells overlap above the scramble. Each pedestrian is a moving user, handed from cell to cell as they walk. At this density, handover parameters tuned by hand are a guess.
02 · Ping-pong
Watch the flicker. Users bounce between two cells — handed over, handed back, handed over again. Every bounce is signaling load, battery drain, and a stutter on someone's video call. 1 in 5 handovers fails or bounces under legacy static parameters.
03 · Why tuning by hand fails
Engineers adjust cell offsets from spreadsheets, weeks after the complaint. But Shibuya at 8:47 is not Shibuya at 14:00. The right parameters change faster than any human can retune them.
04 · The twin learns the crossing
WINNIIO's twin replays the morning from real telemetry, then lets a reinforcement-learning agent retune handover offsets every two seconds — safely, in simulation, before a single live parameter moves.
05 · The storm dissolves
In our lab runs, handover success went from 79.25% to 99.99%. The crossing looks the same from the street. From the network's side, the noise is gone.
Nobody files a ticket for a half-second stutter. They just remember the network felt bad — and remember it again at contract renewal. Dense-urban handover quality is retention, priced in milliseconds.
79.25% → 99.99% and the 2.2M-row pipeline are measured lab results on replayed operator-style data; a pilot reproduces them on your cluster.
One dense-urban cluster, thirty days of your telemetry, one replay. See your own ping-pong storm — and watch it dissolve.
