Design Selection

• Given a scenario, predict the performance of a given frequency and power (active/passive) as it relates to: read distance, write distance, tag response time, storage capacity
• Summarize how hardware selection affects performance (may use scenarios)
• Antenna type
• Equipment mounting and protection

Site Analysis (i.e., before, during and after installation)

• Given a scenario, demonstrate how to read blueprints (e.g., whole infrastructure)
• Determine sources of interference
• Use analysis equipment such as a spectrum analyzer, determine if there is any ambient noise in the frequency range that may conflict with the RFID system to be installed
• Given a scenario, analyze environmental conditions end-to-end

RF Physics
