Speed and bandwidth are the same thing. Power is the other side of that triangle.

But that ignores encoding, and other tricks like signal shaping, frequency multiplexing, and all kinds of fun stuff. Wireless data transmission is complicated. For example: https://en.wikipedia.org/wiki/Quadrature_amplitude_modulation

    Speed and bandwidth correlate but aren't the same. Bandwidth is the amount of data that can pass through a medium and speed is the transmission rate. If you have a gig connection and one device, you can get close to gig speeds. If you have the same gig connection with 1000 devices saturating the medium, you aren't likely to get gig speeds.
