Wireless Local Area Networks (WLANs) have become an integral part of our daily lives. They provide convenient access to the internet and enable seamless communication between devices. However, the performance of WLANs can be affected by various factors, such as interference, signal strength, and network congestion. To optimize WLAN performance, organizations conduct WLAN surveys, which involve analyzing the wireless landscape to identify potential issues and optimize network coverage. However, it is imperative to understand that WLAN surveys have their limitations.
Limitation #1: WLAN Surveys only Covers Wireless Landscape
WLAN surveys are designed to analyze the wireless landscape between the Access Point (AP) and the Wireless Local Area Network Network Interface Controller’s (WLAN NIC) antenna of each device. This means that the survey does not encompass the AP connectivity on the wired side or the operations of any device beyond the WLAN NIC’s antenna. Therefore, the survey results may not accurately reflect the overall network performance.
Limitation #2: WLAN Surveys are limited to a Specific Time
WLAN surveys are conducted at a specific time, which means that the results only reflect the network’s performance during that time. WLAN performance can be affected by various factors, such as network traffic, weather conditions, and neighboring networks’ interference. Therefore, the survey results may not provide a comprehensive picture of the network’s performance.
Limitation #3: WLAN Surveys are limited to a Specific Area
WLAN surveys are conducted in specific areas to analyze the network performance in those areas. However, WLAN performance can vary significantly in different areas of a building or campus. Therefore, the survey results may not accurately reflect the network performance in other areas.
Conclusion
WLAN surveys are an essential tool for optimizing WLAN performance. However, it is imperative to understand their limitations to interpret the survey results correctly. WLAN surveys only encompass the wireless landscape between the AP and the WLAN NIC’s antenna of each device, are limited to a specific time, and are limited to a specific area. Organizations should consider these limitations when analyzing WLAN survey results and take appropriate measures to optimize WLAN performance.
