What you ought to know before deploying an 802.11n Wireless Network

We all know that the IEEE 802.11n standard for Wi-Fi supports up to 600 Mbps for creating a wireless network. But are all 802.11n compliant devices same? Is the 600 Mbps throughput feasible as of today? What other network/ device considerations do we need to account for, to achieve maximum 802.11n throughput levels? These are some of the questions that will be answered in this article.
