I'm trying to learn more about how cell phones operate. Right now I don't understand the power involved in the signal between the cell site and mobile phone. I've read that the average cell phone has a signal strength that ranges in between -80dBm and -120dBm. I've also read that cell phones output between 27 to 33 dBm. What exactly does this mean? Is this related to how much power the cell phone needs to use to effectively communicate with the cell site?
Why is -80dBm considered a better signal than -120dBm? Is this the ampltiude of the signal being transmitted by the cell site? How is this calculated? Thanks - Adam
