The DIAD is a mechanism that helps speed up the process of sharing delivery information with the UPS network and the customers waiting for packages. The DIAD uses Gobi technology, a recent creation that connects drivers with their management network, even if their cellular signals are lost during route. Inside the DIAD, drivers can see their whole daily route ahead of them. If their managers or drivers need to make updates to the route during the day, they can send the information through the DIAD so everyone is on the same page.
