Also known as: Quarter QVGA

QQVGA (Quarter QVGA) is a quarter the size of QVGA, or the rather tiny resolution of 160 x 120 pixels.

Quad-band Phone is a mobile phone that can operate worldwide on the 5 continents using the four main GSM frequency bands.

A quadband phone includes access to the GSM 900 and GSM 1800 bands - the bands available on dual-band phones - that are used in over 150 countries worldwide. These phones also cover the GSM 1900 band - normally included in tri-band phones - and this band is used in parts of the USA, Canada and South America. In addition, a quad-band mobile phone is capable of operating on the more recently allocated GSM 850 frequency band used on the American continents.

Also known as: Quarter VGA, Quarter Video Graphics Array

QVGA (Quarter Video Graphics Array) is a standard for displays and cameras that measures 320 pixels wide by 240 pixels high. Although QVGA is generally only found on Series 80 handsets and some high-end Series 60 phones, it is a very modest resolution for a digital camera, and at a tiny 0.08 megapixels, QVGA picture quality - although better than CIF - won’t be particularly good.

QVGA is however an excellent resolution to use for sending digital pictures via MMS or e-mail, as the image files will be small in bytes - saving on bandwidth - but easily big enough in pixels for enjoyable viewing on another handset.

An even smaller version of QVGA is QQVGA.
