United Parcel Service is transferring its mobile data communictions to a next generation wireless network as it moves to give its delivery drivers faster access to shipment information.

UPS is using AT&T Wireless' new GSM/GPRS wireless network to give fleet employees high-speed wireless access to information through UPS' hand-held computer system – called a Delivery Information Acquisition Device (DIAD).

Some 60,000 drivers will now be able to access voice and data information in the U.S. and Canada to get shipment updates, whether they are in the delivery truck or in the process of making a delivery or pickup, said AT&T.
