I cannot believe a publication like Fortune had articles that contain blatantly incorrect information. Senior editor Peter H Lewis should’ve at least consulted Wikipedia (here and here) before he wrote this article.
You may already see wireless network devices on the shelves marked “pre-n,” and for most people the risk of buying now is minimal.
Two dozen of the top network equipment makers have agreed to align behind the 11n specs, and even if changes occur between now and formal ratification, it’s likely that the hardware you buy today can be upgraded easily with a software download.
The first WiFi devices were based on a 10-megabit-per-second 802.11b
standard. Then came 11g, with a theoretical top data transfer speed of

and 20 mbps to 25 mbps is about average.) Another variant, 802.11a,
intended for moving video over short distances, also took hold.
