In high-density environments, such as stadiums and convention centers, what extra factor has to be taken into account that can attenuate Wi-Fi
signals when these environments are having an event?
What is the minimum PoE budget needed on a switch to support 6 (six) APs that can only be powered using IEEE 802.3at if no other details are
provided?
You told your customer that multipath fading may be mitigated simply by moving one or both of the receivers antennas a small amount, usually by
one to four wavelengths away from its original position. Your customer is prepared to make the change, but does not know the wavelength for
802.11ac.
What is the approximate wavelength of an 802.11ac radio wave?
Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4x4:4 802.11ac
wave 2 capable of using dual-5GHz and have one MultiGig interface. Some cable drops for the APs will run for more than 180.5 feet (or 55
meters). To support MultiGig, what is the best choice of cabling?
You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in
Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise
floor was approximately -94 dBm on this floor of the building. The phones documentation does not specify a recommended RSSI or SNR value for
best performance.
Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas
you are monitoring and where VoWiFi service is desired?
