Why higher frequency allows the signal to carry more data.

AI Thread Summary
Higher frequency signals can carry more data due to their ability to support faster modulation rates, allowing for more bits to be transmitted in a given time frame. In WiFi communications, this means that higher frequencies can accommodate more data channels and increased bandwidth. The analogy of a mail service illustrates that more frequent deliveries can result in a greater volume of information being sent. Understanding modulation schemes and Shannon's theorem further clarifies the relationship between frequency and data capacity. Overall, higher frequency enables more efficient data transmission in wireless communications.

Hello!

Can someone explain why a signal with a higher frequency carries more data that one with lower frequency, namely in WiFi comunications?

Thanks in advance.

What are your thoughts on this? Read a little about different modulation schemes on wikipedia.org, and think about what factors affect how fast you can modulate a carrier wave:

Does that help?

the one that comes once a week or the one that comes once a day?

Is this some Haiku statement of Shannon's theorem? :blushing:

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
