developments in satellite technology have fostered increased communication and productivity within the trucking industry. drivers may input the information from a bill of lading into a simple text-only dot matrix display screen (commonly called a "qualcomm", for their ubiquitous omnitracs system). this allows the driver to communicate with their dispatcher, who is normally responsible for determining and informing the driver of their pick-up and drop-off locations. drivers are no longer required to find the nearest public phone in order to relay information regarding their load status, it can be done without leaving the truck cab.
