Before installing wireless access points in a newly leased warehouse, a wireless engineer walks the entire facility with specialized software and a mobile device to measure signal strength, identify sources of interference, and map coverage gaps. What is this process called?
- ASite survey
- BChange management review
- CPenetration test
- DFirmware audit
Show answer & explanationAnswer & explanation
Correct answer: A. Site survey
A wireless site survey involves physically walking a facility to assess RF characteristics such as signal strength, interference sources, and coverage areas, which directly informs optimal AP placement before installation.
Why the other options are wrong
- B. Change management review pertains to approving IT changes, unrelated to RF measurement.
- C. A penetration test evaluates security vulnerabilities, not RF coverage.
- D. A firmware audit checks device software versions, not wireless coverage.
Wireless Site Survey
A pre-deployment assessment of a physical space to measure RF signal strength, interference, and coverage, used to determine optimal access point placement.
- Produces a heat map of coverage
- Identifies interference sources and dead zones
- Should be repeated after major layout changes
Memory trick: Survey the site before you site the survey equipment... err, before installing APs!
