Question 270

A retail RF design uses an isotropic antenna calculation for a directional panel antenna without considering its beam pattern. What corrective step most directly addresses the wireless fault?

  1. Validate realistic body attenuation, density and busy-hour RF behavior under representative occupancy
  2. Move or correctly antenna-feed the radio so the metal enclosure no longer shields the intended coverage area
  3. Separate radio-layer evidence from higher-layer address-assignment failure before changing coverage
  4. Account for antenna directivity, installed orientation and allowed EIRP in the site survey

Explanation

Correct Answer

D:

RF planning must account for bidirectional signal, noise, building attenuation and actual antenna propagation. In the described case, account for antenna directivity, installed orientation and allowed EIRP in the site survey resolves the identified control gap. Confirm with: Coverage measurements match the intended aisle direction with acceptable limits outside the beam.

Incorrect Answers
