Enterprise WLAN Planning and Design

Which of the following statements are correct regarding WLAN site surveys in various typical scenarios?

Choose four
  • A In a stadium scenario, the onsite environment is complex and cabling is difficult. Therefore, confirm with the property management company about ELV rooms and cabling. If the transmission distance is too long, consider deploying more switches. During the survey, focus on the interference between APs and the AP installation modes.
  • B In a ward-round scenario, high requirements are posed on the coverage field strength, roaming effect, and bandwidth. Determine the interference of medical equipment and the areas where Wi-Fi signals are not allowed.
  • C In an office scenario, the load-bearing pillars and partitions affect the signal coverage. If an integrated ceiling is used, deploy APs near maintenance access panels. If a metal ceiling is used, mount APs on the ceiling or wall.
  • D In a classroom scenario, if the walls are made of reinforced concrete, the signal attenuation is high. In this case, you are advised to test the attenuation during the site survey. Additionally, pay attention to the locations of ELV rooms in the teaching building.
Explanation

WLAN site surveys must account for the physical environment, cabling and access-switch reach, RF attenuation and interference, AP mounting constraints, and service requirements such as coverage, capacity, and roaming. Stadiums have complex high-density RF and cabling conditions; wards require reliable roaming and assessment of medical-device interference and restricted RF areas; office structures and ceiling materials affect AP placement; and reinforced-concrete classroom walls require measured attenuation and infrastructure-location planning.
