TELIT GROUP Industries for Telecommunications 8 Enabling Technologies WAP Bluetooth Java for planned higher bandwidth (Internet) data services Wap allows an efficient way of accessing the web through a mobile terminal. It allows the viewing of images for example on a small display. Although WAP has not taken off as initially predicted, the introduction of ‘always on’ networks is likely to increase the WAP uptake amongst users. Also, with a new version of WAP being sought incorporating X-HTML, which is also the direction in which the internet world is going, WAP is likely to offer more to the end user. Bluetooth offers a specification for short range RF connectivity. This technology will allow handsets to be wirelessly linked to a range of devices such as headphones and laptops. Java is emerging as a key enabling technology facilitating enhanced access to content by providing better graphics and interactive features such as the download of games and music. Expectations are that by the end of 2003, 60% of all phones will be capable of running Java applications.

TELIT GROUP Industries for Telecommunications 1515 Especially in the early stages of service roll-out which will be focused on metropolitan areas initially, the handsets will have to be dual mode. It is important therefore, that handsets should be backward compatible with intermediate standards such as GPRS. Several combinations of multi-mode handsets will be required. Displays will be larger, be in color and offer higher resolutions comparable to present PC resolutions. They will also have to offer increased refresh times to support viewing images and video conferencing. To accommodate technologies such as video coding and over- the-air upgrades, handsets will be 20 to 30 times more complex as enhanced processing and memory capabilities incorporated within. Power consumption will also be a factor as consumers will expect at least the same performance as second generation phones which offer up to eight hours of talk and 200 hours of standby time.
