Bahl's theorem

Bahl's theorem states that for a given wireless communication channel, the maximum data rate that can be reliably transmitted depends on the bandwidth (the range of frequencies used) and the signal-to-noise ratio (how strong the signal is compared to background noise). Essentially, increasing bandwidth or improving signal quality allows for higher data rates. The theorem provides a fundamental limit, guiding engineers in designing communication systems that optimize how much information can be sent over a channel without errors. It highlights the trade-offs and potential of wireless links based on their technical characteristics.
