This is primarily achieved through the use of RSSI (Received Signal Strength Indicator) values, which are a measure of the power present in a received radio signal. The RSSI values are used to estimate the distance between badges, enabling the detection of proximity within a predefined threshold, typically set at about 2 meters by default but adjustable as per the requirements of the event. When two badges come within this set proximity limit, they register each other’s presence, effectively tracking close-range interactions among attendees.
- Rastreo de contactos: In the context of contact tracing, the badge records interactions that occur within the predefined proximity range. This data, which includes the duration and frequency of interactions, is stored in the badge’s memory. Using Bluetooth connectivity, this data can be transmitted to a central server or accessed through a mobile application for analysis. In a theoretical event scenario, this feature allows event organizers to trace and analyze patterns of attendee interactions, crucial for identifying potential high-density areas and contact clusters. In the case of a health-related incident, this data becomes invaluable for tracing potential transmission chains.
- Alert Systems: The badge is equipped with a built-in buzzer and vibrator, which are integral to its alert system. These components are activated when the badge detects another badge within the set proximity limit, serving as a tactile and auditory reminder to maintain social distancing. The buzzer produces an audible alert at 75dB, while the vibrator provides a physical alert with less than 50dB of mechanical noise, ensuring that the reminders are noticeable but not overly disruptive. This dual-alert system is particularly effective in crowded and noisy event environments, where visual cues may be missed.
Además, la funcionalidad NFC (Near Field Communication) de la insignia permite una fácil gestión y configuración de estas funciones, lo que permite a los organizadores de eventos ajustar rápidamente configuraciones como umbrales de proximidad o tipos de alerta para alinearlos con los requisitos cambiantes o las diferentes áreas dentro del lugar del evento.
En resumen, la credencial de rastreo de contactos de Lansitec funciona como una herramienta integral para gestionar la dinámica de las multitudes y garantizar los protocolos de seguridad. Su sofisticado uso de Bluetooth para la detección de proximidad y el rastreo de contactos, combinado con un sistema de alerta eficaz, lo convierte en un recurso teóricamente poderoso en cualquier escenario de gestión de eventos a gran escala, donde mantener el distanciamiento social y monitorear las interacciones de los asistentes son primordiales.
