It was not that many that followed years of ago was almost entirely speculation. If you have ordered something that had to be shipped to you might happen in 3 days or 3 weeks, and where the package was between you and the sender was a complete mystery. This change not only because the GPS tracking, but also because of radio frequency identification (RFID).
GPS is a wonderful technology that revolutionized many areas of our lives; but it is simply too much to put a GPS receiver on each box, package or envelope that is shipped. Is it really necessary for the GPS trace each package. Inevitably, the packages are in a building or truck, so all you need to know is that trucks or construction to your package and where the building or the truck is Obviously the buildings do not move, so you should to GPS tracking packages in a building, you need to just constantly knowing exactly which packages are in the building.
Shipment and delivery trucks are of course a different matter. Trucks must be followed by GPS to track packages in them. Very soon, each new delivery trucks hit the streets will have a fully integrated GPS tracking system. Old truck will be updated at the end with GPS, sooner than later, or truck probably will be removed completely. GPS truck transport is used primarily to allow the sender and the shipping company sa where are packages. GPS can also be used for navigation, but most of the truckers already know their territory and do not need GPS navigation. The push for a delivery truck with GPS is for tracking packages.
Therefore, the only thing left to make the system work is electronically tag each package. In the State of the art system of close future packages will be identified by RFID. Won't be long before RFID electronic tags that will be attached to almost all packages shipped anywhere in the world. Unlike current bar coding systems, electronic RFID tags do not require a Visual scanning and can bring much more information. Bar coding is almost everywhere these days, but it requires a close and accurate visual scanning a barcode reader. It is simply too slow and often inaccurate. A RFID Tag, however, require only that the package is in the range of radio frequencies or RFID RFID interrogator receiver. The days of running a package as a Visual scanner by hand are almost over.
Even today, most shipping companies have prototype and fully integrated delivery trucks, RFID, RFID interrogators, followed by GPS and computer network antennas cell equal all together. Factories, shipping and mail centres are also starting to use RFID in all their facilities so they know exactly what packages are in their structures. If monitoring package will soon be full circle. Send the package, or to send a radio signal frequency, RFID interrogator in the back of the truck or building catches the signal, computer on trucks or construction sends a quit message senders cell computer to know what is there, and finally the GPS system indicates the sender when the truck is whether the package is currently on a truck.
