7.2-1. Characteristics of wireless links. Which of the following statements about the characteristics of wireless links are true? 0 Path loss refers to the decrease in the strength of a radio signal as it propagates through space. Path loss refers to link-layer frames that are corrupted due to the higher bit error rates in wireless channels. Path loss refers to the dropping of link-layer frames that are being relayed among wireless access points due to buffer overflow, just as network-layer datagrams are dropped at routers with full buffers. The bit error rate (BER) of a wireless channel increases as the signal-to-noise ratio (SNR) increases. The bit error rate (BER) of a wireless channel decreases as the signal-to-noise ratio (SNR) increases. The "hidden terminal problem" refers to the fact that many people can never seem to find their mobile phones. The "hidden terminal problem" happens when A sends to B over a wireless channel, and an observer, C (that can be even closer to A than B), does not detect/receive A's transmission because of physical obstacles in the path between A and C. The "hidden terminal problem" happens when A sends to B over a wireless channel, and an observer, C (that can be even closer to A than B), does not detect/receive A's transmission because of physical obstacles in the path between A and B. The "hidden terminal problem" happens when A sends to B over a wireless channel, and an observer, C (that is further away from A than B), does not detect/receive A's transmission because the signal strength of A's transmission has faded significantly by the time it reaches C. Multipath propagation occurs when portions of the electromagnetic wave reflect off objects and the ground taking paths of different lengths between the sender and a receiver, and thus arriving at the receiver at slightly different points in time. Multipath propagation occurs when a sender sends multiple copies of a frame to a receiver, which is relayed over different by base stations or other wireless devices to the receiver.
