Radio Tail Timer: Telemetry Upload Battery Cost

Every telemetry event a mobile app sends home — a metric, a log line, a trace span — has to travel over a radio that is normally parked in a low-power idle state. This simulator renders the resulting phone-to-tower link in 3D: telemetry events queue up as glowing dots on the device, a flush sends them flying to the tower and promotes the radio to its high-power state, and the radio then lingers there for a configurable tail timer before dropping back to idle. Adjust the event rate, the batch-flush threshold, and the tail timer to see how "send everything immediately" instrumentation pins the radio awake and drains the battery far faster than the same data sent in fewer, larger batches — with live readouts for battery remaining, radio duty cycle, and wake-ups per minute.
