During a site survey, which consideration helps minimize interference from neighboring networks?

Using higher frequency bands is the correct choice for minimizing interference from neighboring networks during a site survey. Higher frequency bands, such as those used in 5 GHz Wi-Fi, have shorter wavelengths and can support more channels, which leads to better channel separation. This reduces the likelihood of interference since there are more non-overlapping channels available for use. This is particularly useful in environments where multiple networks are operating simultaneously, as higher frequencies often encounter reduced interference and congestion compared to lower frequency bands.

In contrast, maintaining old network infrastructure does not necessarily address interference issues; rather, it may perpetuate existing problems. Selecting the cheapest equipment could lead to inadequate performance and limited capabilities to manage interference effectively. Ignoring client needs would detract from the overall goal of providing a reliable and efficient network, ultimately exacerbating interference scenarios. Hence, using higher frequency bands stands out as a strategic consideration for reducing interference.
