What is one potential obstacle to wireless signals during a site survey?

Wireless signals can be significantly impacted by physical obstacles, and metal shelving is a prime example of such interference. In a site survey, the placement and materials of objects within a space can influence signal strength and quality. Metal, in particular, can absorb, reflect, or refract wireless signals, leading to dead zones or decreased coverage in certain areas. This creates an environment where the effective range of wireless communication can be compromised, as the metal structures disrupt the normal propagation of radio waves.

In contrast, while installed software updates, inconsistent device charging, and frequent software upgrades might affect the performance or functionality of devices, they do not directly interfere with the physical transmission of wireless signals in the same way that metal shelving does. These factors can impact user experience or device operation but won't obstruct the wireless signals themselves during a site survey.
