WMAN: Wireless Metropolitan Area Network
Véase también: Red de área metropolitana
Para redes de área metropolitana se encuentran tecnologías
basadas en WiMAX (Worldwide Interoperability for
Microwave Access, es decir, Interoperabilidad Mundial
para Acceso con Microondas), un estándar de
comunicación inalámbrica basado en la norma IEEE
802.16. WiMAX es un protocolo parecido a Wi-Fi, pero
con más cobertura y ancho de banda. También
podemos encontrar otros sistemas de comunicación
como LMDS (Local Multipoint Distribution Service).
WWAN: Wireless Wide Area Network
Véase también: WAN
Una WWAN difiere de una WLAN (Wireless Local Area
Network) en que usa tecnologías de red celular de
comunicaciones móviles como WiMAX (aunque se
aplica mejor a Redes WMAN), UMTS (Universal Mobile
Telecommunications System), GPRS, EDGE,
CDMA2000, GSM, CDPD, Mobitex, HSPA y 3G para
transferir los datos. También incluye LMDS y Wi-Fi
autónoma para conectar a internet.1
