Now that 802.11n has been officially ratified, attention is turning to the next big thing in wireless networking: gigabit WiFi. Ars explores the future of WiFi and how it may give gigabit Ethernet a run for its money.
In a couple of years, crossing the 1Gbps threshold with a WiFi access point will be routine. That access point will likely have two radios, one for each major spectrum band, and support a host of older flavors for compatibility. Eventually, WiFi will approach the robustness and speed needed to make it a completely viable replacement for Ethernet for most users.
