Over the past few years, many fundamental changes have taken place in wireless communications that will influence the future of this dynamic field. One phenomenon driving these changes has been the integration of wireless communication devices in people’s lives. While the 1990's were the years when wireless voice telephony became popular, the 2000's should be the time when wireless data applications are truly untethered from homes and offices. As more people adopt wireless communication devices and applications effected by these devices, the demand on wire-less networks will continue to grow.
