A company has set up a new wireless network in their office located on the fifth floor of a commercial building. The IT consultant recommended placing high-gain antennas near the exterior windows to provide better signal coverage. However, the network administrator is concerned about security implications of this placement. What is the primary security concern with positioning high-gain antennas near exterior windows?
Antennas near windows will primarily receive signals from other networks, leading to network confusion.
High-gain antennas near windows can cause excessive signal reflection and interference within the network.
The presence of glass can amplify the wireless signal and cause damage to the antenna.
Signal spillover can extend beyond the intended coverage area, allowing for potential unauthorized external access.
