WAP-enabled phones, still relatively scarce items, are expected to be widely available during the second half of this year. Applications, which need only be developed once, can then be used on any type of device. By 2004, the Yankee Group projects about 5 million WAP-enabled handsets in the market. But WAP will still need to hurdle the Web's relatively high bandwidth requirements. It takes anywhere from 2.5G to 3G for a device to offer enough capacity to browse the Net, transfer large files and download streaming video files.
Various carriers plan high bandwidth technologies.
All the carriers painted a picture of a day when data would be the primary wireless signal and voice would be secondary.
