The document traces the history of mobile phone design from 1946 to the present, highlighting several milestones. It describes the first wireless telephone calls from cars in 1946 but notes the primitive system allowed only 12 calls at a time in New York. In 1981, the first portable units were introduced, called "transportables" or "luggables", too large to carry due to battery size. In 1983, Motorola's DynaTAC 8000X was the first true mobile phone, weighing about a bag of sugar with 8 hours of battery life and costing $3,995. Digital GSM networks in 1989 increased phone usage throughout the 1990s with black or grey phones and small screens.

is a wireless industry term for a
collection of international standards
and technologies aimed at
increasing efficiency.
Increasing data rates will mean that
most phones will have cameras and
larger screens to enhance the

Designers often have one eye on
the future to try and predict what
technologies and styles will be
common.
The next few slides show sample
