How could WiMAX improve this picture?

1.    The delivery companies could cooperate and graduate and build a nationwide WiMAX network (or at least in the most dense urban areas).

2.    Step 2 is where delivery people have WiMAX tablet type notebooks that scan the packages as they are delivered such that as packages are delivered that info is fed into the customer-accessible online database that would read "Package delivered 2:42 PM delivery truck #345". That device could be SMS and/or VoIP enabled providing real-time communications with a driver. Customers expecting a package that they would have to sign for could drop a short message to the driver "Yo, goin' out for a Starbucks back at 3 PM sharp, I promise! See ya then!"

3.    WiMAX telematics could be brought into play so that dispatchers would know where each delivery truck was in real time without having to radio the driver for his or her "20" (location). Many inefficiencies could be taken out of the system thus boosting profitability.

4.    Most delivery companies use bar code now but want to move to RFID. RFID readers could then relay that info via WiMAX as a backhaul to the larger network. That way, the reader could even be mobile and some packages might not even have to go through a warehouse for barcoding/scanning/logging. RFID could also interface with a WiMAX subscriber device in the delivery truck so that the delivery company could tell customers in real-time exactly where the package was.

5.    The first WiFi phones were incorporated into Symbol's bar code reader so that warehouse people could scan and talk at the same time. Really. WiMAX could be used to blanket enormous warehouse facilities with WiMAX such that multiple WiFi access points need not be installed and managed over that great complexes.
