With other emerging technologies, the computer communications field has found its way into vehicles. If a vehicle can be located, it can also be sent a message and vice versa. This method of contact can also be done with cellular communications by using three cell towers. Your vehicle can be triangulated and the position will appear on a computer monitor in the dispatcher's office. This type of communication is the most expensive but offers additional features that could generate cost savings.
Some insurance companies offer discounts for equipment that locates vehicles after theft.
The expense of drivers being off their route is another consideration in the purchase process. The cost for this system is similar to that of two-way radio. The big ticket item for this type of communication is the computer and specifically the software. It takes considerable time and money to develop these maps and the companies that have the technology will charge license fees to the vendor of the software and of course they will pass it on to you, the end user. In conclusion, there are several different ways to communicate with several different pricing levels.
