Given: As you prepare for a site survey in a hospital, you have learned about several wireless
devices that support connection-oriented, real-time applications. These applications are sensitive
to service interruptions and require excellent signal quality, low latency, and low loss. For that
reason, it is important to identify sources of RF interference as well as building characteristics that
would cause RF blockage or dead spots.
What systems or environmental characteristics are most likely to cause interference or RF
blockage and disrupt service for these applications? (Choose two)
