Wireless Lan (WLAN)
Improving performance, range, and reliability in 802.11n networks
While the hooks to achieving high-performance, ubiquitous wireless access in the home or office are within the IEEE 802.11n standard, there are many options built in for sustaining signals to achieve higher effective throughput at greater distances. The key is to choose the correct options. This feature will help, with an eye toward balancing cost and complexity.
