Spectrum: The radio frequency spectrum ranges from very low frequency radio waves  at around 10kHz (30 kilometres wavelength) up to 100GHz (3 millimetres  wavelength). The radio spectrum is divided into frequency bands reserved  for a single use or a range of compatible uses. Within each band,  individual transmitters often use separate frequencies, or channels, so  they do not interfere with each other.

Spectrum is divided between different types of technology

your AM and FM channels are all spread around 100MHz - 200MHz.

Telecom spectrum starts from 800MHz, and goes up to 2300MHz. 

Bluetooth - Wi-Fi used to be 2.4GHz (2400MHz) 

 bands for cellular communication are 800MHz, 900MHz, 1800MHz, 2100MHz, and 2300MHz.

 Bandwidth is defined as the maximum amount of data that can be transmitted in a fixed amount of time. It is the range of lowest to highest frequency.

For digital devices, the bandwidth is usually expressed in bits per second(bps) or bytes per second. For analog devices, the bandwidth is expressed in cycles per second, or Hertz (Hz).

An internet connection with a larger bandwidth can move a set amount of data (say, a video file) much faster than an internet connection with a lower bandwidth.

Bandwidth is typically expressed in bits per second, like 60 Mbps or 60 Mb/s

Bandwidth is maximum data rate

What is Data Rate Data rate (or data transfer rate) is the

amount of data being transferred through a connection within a second. Data rate cannot be higher than the bandwidth of the connection. Data rate is also measured in ‘bits per second’ or bps. Sometimes data rate is also called as bit rate.
