Quad band (also known as quad-band or quadband) literally means four bands. Most people come across the term when it is used to describe a mobile phone supporting four frequency bands. Having more than one frequency in one device is useful to enable roaming between different countries that peg the allowed transmission frequency at different values or to allow a better coverage in the same country.
