Given: As the wireless network administrator for XYZ Company, you are planning to upgrade your aging wireless network infrastructure, as well as
some clients, to support 802.11ac. In your research, you have discovered that your new wireless client devices and infrastructure are 802.11ac,
WMM, and WMM-PS certified by the Wi-Fi Alliance. Some of your existing client devices are 802.11a/b/g devices that do not support WMM.
Given this information, what scenario is possible when your company's employees begin using both types of client devices on the new WLAN?
As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular
applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.
What application matches this description?
Assume that your network operates in a regulatory domain that allows use of the entire 5 GHz space allowed in the 802.11ac amendment. In your
upcoming
802.11ac deployment, you would like to take advantage of the performance improvements that result from channel bonding. However, after
extensive testing, you have determined that your mission-critical WLAN should not use channels requiring DFS support.
Given those two criteria (enable channel bonding and disable DFS channels), in the 5 GHz spectrum, how many non-overlapping 40 MHz channels
will your system be able to use?
Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?
