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.
