The system mainly consists of a transmitter (host), a receiver (guide), and a back-end content management platform.
The transmitter connects to the exhibition hall's positioning equipment or management system via a USB interface, converting digital signals such as exhibit numbers and audio/video content into wireless signals (e.g., in the 2.4GHz band) for transmission. The receiver is equipped with a high-sensitivity antenna, enabling real-time signal reception and decoding for playback. The system uses a non-touchscreen design, allowing content access via physical buttons or a mobile app, avoiding distractions from screen operations. Its wireless transmission range covers the typical exhibition hall space, and signal stability is minimally affected by environmental interference.
