Cellular Phones

We have seen an explosion in cell phone usage. In some countries in southern Europe (for example, France and Portugal), mobile penetration is higher than that of fixed-line telephony. The biggest surprise has been
Europe and Japan, where the youth market has become an important user group.

The usage has been higher in Europe and Asia than in the United States, but the latter is catching up as a result of new networks that enable better coverage and lower fees. The technical evolution has gone from analog networks like NMT (Nordic Mobile Telephony) and CDMA (Code Division Multiple Access) to digital networks such as GSM and TDMA (Time Division Multiple Access) that enable data communication with much higher bandwidth (greater speed).

The digital networks enabled WAP (Wireless Application Protocol), which was expected to reach high penetration levels after the millennium shift. WAP is a text-based protocol, which does not enable the use of graphics in its applications. However, the expectations were not met. Despite the fact that most mobile phones in Europe are WAP enabled, very few people actually use existing WAP services. The reason for this failure is the poor text-based interface in combination with a relatively complex connection procedure. Furthermore, end-user pricing associated with using WAP services also acted as a deterrent that prevented widespread adoption of this service.

This makes smartphone users the only group that actually uses WAP—they’ve gotten accustomed to reading e-mail on their smartphones. The smartphone is a cell phone with some PDA functionality, which often uses
WAP for communicating with services residing on the Internet (mail and calendar services).
