What do site surveys help to identify in a wireless setup?

1. User access permissions

2. Existing access points and signal strengths

3. Hardware configuration issues

4. Asset management discrepancies

The correct answer is: Existing access points and signal strengths

Site surveys in a wireless setup play a critical role in understanding the physical environment where the wireless network will operate. The primary purpose of conducting a site survey is to assess the existing conditions, which includes identifying existing access points and measuring signal strengths throughout the coverage area. By analyzing the current access points, the survey helps to determine whether they are positioned optimally for coverage and performance. Signal strength measurements identify areas with weak coverage, interference from other devices, or obstacles like walls and furniture that may affect the wireless signals. This information is essential for planning the deployment of new access points, ensuring adequate coverage, and addressing potential dead zones within the intended wireless environment. While user access permissions, hardware configuration issues, and asset management discrepancies are important considerations in network management, they are not the primary focus of a site survey. Instead, the survey zeroes in on the actual radio frequency environment to optimize the wireless infrastructure.
