A technology that allows transmission of data via a computer, without having to be connected to a fixed physical link is called mobile computing. The advent of wireless networks has greatly increased the possibilities for mobile computing offered to the general public. Miniaturization has aided this trend towards increased user mobility with the development of notebook computers and Personal Digital Assistants (PDAs) which are truly portable. Currently, the most popular form of wireless communication is the cellular phone...............

Mobile computing has been undergoing a bit of a renaissance lately. A few years ago it was a simple matter of finding a data-compatible mobile phone, a PC card modem, and a matching cable and installing it as a modem. Then people started to use PDA’s as well. Cell phones started to come with infrared ports to allow communication with laptops. Then cell phones started to come with modems built in. The connecting methods of mobile computing, its introduction, connection types, factors affecting connections, mobile applications and its limitations are explained...............

With increasing use of small portable computers, wireless networks, and satellites, a trend to support “computing on the move” has emerged. This trend is known as ‘mobile computing’ or ‘anywhere’ and ‘anytime’ computing. Some people refer it to as ‘Nomadiac computing ’.It enlarges the usability of computers, but raises the demanding challenges. Mobile computing can easily mobilize your corporate applications, extending them to most wireless devices while providing an enterprise-grade, carrier-class solution that is network, device and carrier interoperable..............
