Voice over WLANs

Redes de Área Local Inalámbricas

Descripción

The cost of a Wi-Fi interface has dropped from several hundred dollars to essentially zero; a Wi-Fi card is now a standard component in virtually every laptop sold. The penetration of that technology is now expanding to cell phones, PDAs, digital cameras, and other types of consumer electronics. Data rates have grown to 54 Mbps, and the new 802.11n radio link could push that to hundreds of millions of bits per second. Along with that we have seen important developments in security and manageability that make WLANs a trusted technology element in enterprise environments.
