Topic #: 1
In a wireless link, as the signal strength decreases, what else may decrease?
Signal Strength and Data Rate:In wireless links, weaker signal strength often directly correlates to reduced transmission speeds. Modern wireless technologies use adaptive modulation and coding, sacrificing speed for reliability when signals become weaker.
Noise and Interference:While thesecanimpact performance, they don't inherently decrease simply because signal strength drops.
Latency:Latency can be affected by poor signal, but its primary drivers are distance and network congestion.
