Mobile Computing

They were originally electronic devices such as radio transmitters, wireless communications systems and they were operated at fixed locations and were operated with large antennas towers. The growing use of automobiles gave a rise to smaller devices. The large industries started to support the growing use and need for mobile devices, such as taxi radios, police radios, and any other 12-volt dashboard equipment. There are many types of mobile computing platforms, which include dash-mount VGA displays and computers that have a GPS and other types of navigation functions.

The Boundary Between, mobile and portable
Near the 1980’s the boundary between mobile (vehicular) and portable (wearable or handheld) computing started to blur. It started with the “bag-phones” that had a cigarette lighter plug so that it could be used in the vehicle, but was small enough to be carried around for potable use. The 12v mobile phones were being used as potable phones. Today, the boundary between mobile and portable are fuzzy, many small handheld phones and computers still operate off 12 volts from a cigarette lighter socket, and they run off of the self contained batteries that are inside off the divice. Now vehicles have a computer device built into them such as GPS.

Mobile Computing: In-Vehicle Computing and Fleet Computing
In many of today commercial field forces had deployed a ruggedized portable computer like the Panasonic Toughbook 29 in the fleet of vehicles. The units to be anchored for the safety of the driver, device security and user ergonomics.

Security Concerns
The earlier phones were limited to the security feature. This leaded to problems such as avaraity of identity theft, and scanning. The whereby third parties that were in the local area could intercept the call and listen in on the calls. Altough that more recent digital systems, such as GSM, have attempt to address these fundimental problems, but security problems continue to presist.
