What is a Mobile Computer?

The definition of mobile computing is being able to use a computing device even while changing locations. It is also the ability to use computing capability without a connection to a network to access or update information. These definitions may sound like a laptop, but it is quite different.

A mobile computer, also called a portable data collector and portable data terminal (PDT), in its most basic form is a barcode scanner with a display and an operating system. In fact, a lot of people will call a mobile computer a barcode scanner.

The difference is a barcode scanner has to be linked to a host computer to pass on the scanned information. A mobile computer, on the other hand, acts as its own host. You can upload your program or database directly on to the device so that updates and edits can be made while scanning on the go.

Another distinguishing feature of mobile computers is that they have an actual operating system, such as Windows. This allows you to do anything you would be able to do on a PC on your mobile computer. Mobile computers also support many options that a barcode scanner does not, such as wireless 802.11 communication, cellular, terminal emulation, camera, GPS, touch screens, and keypads.

Mobile computers are highly customizable and vary in size and shape depending on the environment. They range from rugged and bulky to light and compact. They can be held like a cell phone or be equipped with a pistol grip. Mobile computers can have three keys, or they can have up to 56 keys. What is needed in a mobile computer is up to the user and the application. There are even mobile computers that attach to forklifts.

Finally, a mobile computer’s required accessories are sold separately, unlike a barcode scanner which usually has the basic accessories in the box. You will need a charging cradle to charge the device, as well as a communication cable for it to talk with a computer. You will need a power supply and line cord to power the cradle, and sometimes you will even need to purchase the battery separate. There are also carrying cases and screen guards to protect the device. With so many accessories, it is best to consult with a professional to see what is needed for a specific device in your application.
