18
Q

You have to perform a WLAN site survey for an 802.11 system in a 20-story multi-tenant building. What should you consider during the planning and implementation stages of the site survey?(Choose Two)

A

~Other Tenants’ WLANs
~The cell coverage should extend only one floor above and one floor below to create a three-dimensional channel reuse pattern.

19
Q

A hospital uses a connection-oriented application in the cardiac care unit. Management wants the application available over a WLAN. Uptime is very important because of the critical nature of the monitoring system. What should the site survey engineer be looking for that might cause loss of communication over the WLAN? (Choose Three)

A

~Safety Glass
~Medical equipment RF interference
~Elevator Shafts
