Helmi climbed onto Santa’s sleigh roof, inspecting the damage from last year’s chaotic flight. Burn marks streaked across the canopy, with melted edges and even a few tiny holes puncturing the enchanted red surface. The culprit was obvious: overheated onboard computers, pushed to their limit trying to process real-time data while relying on patchy LTE coverage. “Too much strain, too little reliability,” Helmi muttered, running a hand over the charred spots. High latencies and weak connections had forced the sleigh to overcompensate, and the result was clear—literally burned into the sleigh.

Back in the workshop, Helmi worked tirelessly. First, they scrapped the energy-hungry digital systems responsible for last year’s meltdown. In their place, they built a compact analog edge-computing cluster. This system processed data directly on the sleigh, eliminating the need to send everything back to the cloud. It was fast, efficient, and ran so cool it wouldn’t melt a snowflake. To top it off, Helmi fine-tuned the sleigh’s antenna to make better use of limited LTE coverage, prioritizing only critical data for transmission.

By nightfall, the sleigh was gleaming with its new upgrades. Helmi gave the roof a final pat and grinned. “No burn holes, no lag, no overheating. This sleigh is now cooler, smarter, and ready for the North Pole skies.” The reindeer snorted their approval, eager to test the setup.
