As you prepare for a site survey in a multi-floor corporate office, 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 2)
