A network technician is tasked with planning a new wireless network deployment for an office building. The technician has the architectural blueprints for the facility. Which of the following is the MOST crucial step to take to ensure optimal and secure wireless coverage?
Use a predictive modeling tool with the blueprints to determine access point placement.
Conduct a physical site survey to identify RF interference and physical obstructions.
Place access points near existing network drops as indicated on the blueprints.
Calculate the required number of access points based on the building's total square footage.
While architectural blueprints are useful for an initial predictive survey, they do not provide information about potential radio frequency (RF) interference, the signal attenuation properties of various building materials, or other environmental factors. A physical site survey is essential to identify sources of interference (like neighboring networks, microwave ovens, or industrial equipment), discover unexpected physical obstructions, and measure actual signal propagation. This allows for the strategic placement of access points to ensure comprehensive coverage, strong signal strength, and a secure and reliable network, which cannot be guaranteed by blueprints alone.
