When I have full bars vs only one or two bars i say the signal is stronger. Is that literally just a higher amplitude wave? Why does service slow dawn as opposed to just stop when my phone can no longer read it?

When you have fewer bars of service or weak WiFi, it means your phone is getting a weaker signal from the tower or router. This isn’t just about a higher amplitude wave; it also involves factors like distance, obstacles (walls), and interference from other devices.
With a weak signal, your phone and the network have to work harder to communicate. They spend more time correcting errors, lower the data rate to keep the connection stable, and resend lost data, all of which slow down your service instead of it just stopping completely.
Think of it like talking to someone far away: when you’re close, you hear each other clearly and talk quickly (full bars). When you’re far away, you need to shout or repeat yourself, and it takes longer to understand each other (few bars).
