HEDY LAMARR
Hedy Lamarr nacida en Viena en 1914 es la inventora del primer prototipo de lo que hoy
conocemos como wifi, intentando aportar todo lo que podía al sector de las
telecomunicaciones, creando así un sistema de comunicación secreto.



¿QUE ES?
El WiFi es un mecanismo que permite, de forma inalámbrica, el acceso a Internet de
distintos dispositivos al conectarse a una red determinada, esta es posible gracias al
uso de radiofrecuencias e infrarrojos.




TIPOS DE RED WIFI
● WPAN: Wireless Personal Area Network.
● WLAN: Wireless Local Area Network.
● WMAN: Wireless Metropolitan Area Network.
● WWAN: Wireless Wide Area Network.



FRECUENCIAS MÁS USADAS
Actualmente se utilizan dos grupos de
frecuencias en WiFi 2,4 GHz y 5 GHz. El
primero, el más utilizado hasta ahora, tiene
alrededor de 80 MHz para poder transmitir
toda la información y todas las redes que se
pueden encontrar en un mismo sitio.
