What is a primary concern when selecting locations for wireless access points?

When selecting locations for wireless access points, a primary concern is the presence of physical obstructions that could cause interference. Wireless signals can be significantly weakened or obstructed by materials such as concrete, metal, or large furniture, which can disrupt the communication between the access point and client devices. By carefully considering the layout and identifying any barriers that might impede signal propagation, a technician can optimize the coverage and performance of the wireless network.

Other factors, while relevant, may not have the same immediate impact on the effectiveness of the wireless signal. Cost considerations pertain more to the overall budget of the installation rather than signal integrity, and while environmental cleanliness is important for equipment longevity, it does not directly influence signal quality. Lastly, the number of users in the vicinity can help inform how many access points are needed and their capacity requirements, but it does not address the signal interference that obstructions might cause. Therefore, ensuring clear pathways for wireless transmission is crucial for a robust and reliable network.
