What issue may arise from the presence of hidden nodes in a BSS?

The presence of hidden nodes in a Basic Service Set (BSS) can indeed lead to a high retransmission count for certain clients. Hidden nodes occur when two devices are within range of the same access point but are not within range of each other. This can lead to a situation where both devices attempt to send data to the access point simultaneously without being aware of each other's transmissions, resulting in collisions.

When a collision occurs, the data packets from the devices cannot be successfully transmitted, leading to errors. As a result, the affected clients must retransmit their data, which increases the count of retransmissions. These retransmissions contribute to network inefficiencies, increased latency, and can degrade the overall performance of the wireless network. Therefore, recognizing the implications of hidden node scenarios is critical for maintaining optimal performance in a wireless network setup.

Conversely, low signal strength for all clients typically stems from distance or obstacles between the clients and the access point rather than hidden nodes. Increased network speed is unlikely in the presence of hidden nodes because the collisions and subsequent retransmissions will slow down effective data throughput. Reduced channel interference does not directly relate to hidden nodes; in fact, hidden nodes can contribute to increased interference instead of reducing it. The presence of hidden nodes complicates
