DSRC (Dedicated Short-Range Communications) is a wireless communication technology that enables vehicles to communicate with each other and other road users directly, without involving cellular or other infrastructure.

Dedicated Short-Range Communications (DSRC) is a wireless communication technology designed for direct vehicle-to-everything (V2X) interactions. It enables vehicles to communicate with each other, pedestrians, cyclists, and roadside infrastructure like traffic signals and electronic signs12.

DSRC operates in the 5.9 GHz band and is based on the IEEE 802.11p standard1. It supports various applications, including:

Emergency warning systems for vehicles Cooperative adaptive cruise control Intersection collision avoidance Electronic toll collection Vehicle safety inspections12 This technology aims to enhance road safety and traffic efficiency by providing real-time information and alerts to drivers.

WiMAX, siglas de Worldwide Interoperability for Microwave Access (interoperabilidad mundial para acceso por microondas), es una norma de transmisión de datos que utiliza las ondas de radio en las frecuencias de 2,5 a 5,8 GHz y puede tener una cobertura hasta de 70 km.
