This paper presents the architectural design and theoretical analysis of a wireless bus bell system designed to replace outdated wired bells and conductor whistles. Our system utilizes a three-component architecture: a handheld, rechargeable transmitter for the conductor; a central relay unit to ensure robust signal transmission; and a receiver bell in the driver's cabin. A key innovation is the transmitter's unique charging mechanism, which draws power directly from the bus's ticketing machine for uninterrupted operation. Based on theoretical modeling, the proposed design is shown to provide reliable, low-latency communication and simplify installation significantly. This design provides a practical, low-cost solution that enhances operational efficiency and safety in public transportation, making it a viable upgrade for modern fleets.
