To ensure maximum flexibility in field transmission capabilities, DIAD IV includes multiple wireless connectivity options. Each DIAD IV features a built-in GPRS or CDMA radio, an acoustical modem to facilitate dial-up access if necessary, and 802.11b wireless local area network connectivity to enable transmission in a UPS center. The DIAD IV also features a Bluetooth wireless personal area network and an infrared (IrDA) port to communicate with peripheral devices and customer PCs/printers.
DIAD IV introduces a revolutionary new feature - Global Positioning Satellite (GPS) - to the handheld terminal market. UPS plans to use this technology to provide drivers with more detailed directions to pick-up and delivery points in order to improve customer service.
The monochrome screen on previous DIADS has been replaced with a color screen that accommodates more information which can be displayed in an easier-to-read manner. The color screen also enables UPS to color-code messages transmitted to a driver's DIAD. Urgent customer pick-up messages, for example, can be color-coded to alert the driver.
In addition, the DIAD IV contains 128 megabytes of memory - 20 times the capacity of the DIAD III. UPS will use this expanded capacity to provide new and improved customer services. Like its predecessors, the DIAD IV's battery lasts an entire work day.
The DIAD IV sends delivery information to the UPS data repository as soon as the delivery information is entered. Drivers simply scan the package bar code, collect the receiver's signature electronically, type in the last name of the receiver and push a single key to complete the transaction and send the data. There is no need to activate a cell
