Band

Range of radio frequencies between two defined limits which are used in wireless communications. 800 to 1900 MHz is the band used for CDMA. Whereas 900 - 1800 and 1900 are used for GSM.

 

Bandwidth

The capacity of a transmission channel. Bandwidth is dependent on the frequency ranges available. The 'bandwidth' or the width of a frequency band determines maximum transmission speed available to subscribers. Each radio channel has a center frequency and additional frequencies above and below this carrier frequency which is used to carry the transmitted information.

Bluetooth

A short range (10' or so) radio protocol that operates in the 2.4GHz band. Bluetooth devices have 'profiles', such as HFP (handsfree profile), DUN (dial-up networking), OPP (object push protocol), FTP (File Transfer Protocol), etc that allows portable devices to interact with each other. Most commonly known for wireless headsets, which use the Handsfree or Headset profile, Bluetooth can also be used to link a cell phone to a computer and exchange files using OPP, FTP or use the phone as a modem using DUN.
Note that using a Sprint phone as a modem requires the PAM (Phone As Modem) plan to be added to your account, typically incurring additional costs.
