A technician is asked to purchase and install a line-of-sight wireless system that provides a stable network connection between two buildings. Which of the following needs to be considered prior to purchasing the system?

The IP address range is important for network configuration and management but does not directly affect the installation or performance of a line-of-sight wireless system. This choice is more relevant to the internal network setup after the system is already in place rather than a pre-purchase consideration.

While SSID broadcast is significant for network visibility and user access, it does not influence the physical installation or the operational capabilities of a line-of-sight wireless system. This aspect can be configured after the system has been installed and is not a critical factor in the purchasing decision.

Firewall rules pertain to security measures that protect the network from unauthorized access and attacks. Similar to IP address range and SSID broadcast, these rules are more pertinent to the network's operational phase rather than the initial purchase and installation considerations for the wireless system.
