Introduction
What are the different modes of an Access Point (AP) operation?
Where can I download the latest firmware, drivers, and software for my wireless network?
What Cisco Aironet products are Wi−Fi certified?
How does roaming work? Who roams when there is not enough signal strength, the client or the AP?
What is fast roaming?
Can the radios be damaged if they are operated without the antennas attached?
What are all the authentication mechanisms currently supported by Cisco Access Points (APs)?
Do I need a license to operate WLANs?
Can I use my wireless device on an aircraft?
What is channel interference?
What is World Mode?
Are the WLAN cards safe to use from a health perspective since they use microwave frequencies?
The FCC limits the maximum system power to 4 watts Effective Isotropically Radiated Power (EIRP) for non
point−to−point systems. However, a properly tested and certified system is allowed to exceed the 4 watt EIRP
for a point−to−point system. I have two parabolic dishes aimed at an Omni. Can I exceed the 4 watt EIRP
limit if I consider each leg point−to−point?
My WLAN system sees radio frequency interference (RFI) or electromagnetic interference (EMI) from
another device. What can I do?
Would the frequency hopping (FH) equipment of another vendor that sits next to our direct sequence (DS)
equipment have any negative effect?
My WLAN system sees interference from a cordless phone. What can I do?
What is the maximum speed of 802.11 a,b,g standards?
Does Cisco currently support 802.11n?
What antenna should I use for the Cisco Aironet 1010 access point?
I have an access point about 50 feet away from my client. The signal is very weak and there is significant
interference in the path (paper storage). What should I do to obtain proper coverage?
What type of antennas should I use for bridges?
Where should I install my access point?
Does Cisco provide any management software or a device to manage multiple access points (APs)?
What is Dynamic Transmit Power Control (DTPC) and how does it work?
What is the difference between 802.3 bridging and 802.11 bridging?
If I wish to install antenna at some distance from an access point (AP), which extension cable do I need
between the AP and the antenna?
