Mobile computing can be defined as a computing environment of physical mobility. The user of a mobile computing environment will be able to access data, information, or other logical objects from any device in any network while on the move. A mobile computing system allows a user to perform a task from anywhere using a computing device in the public (the Web), corporate (business information) and personal information spaces (medical record, address book).
A computing environment is said to be mobile if it supports these characteristics: user mobility (the user should be able to use the same service from one place to another), bearer mobility (the user may movie from one bearer to another but use the same service), host mobility (the user device can be either a server or a client), and service mobility (the service should remain enabled if the user changes from one service to another).
Wireless Application Protocol (WAP) is a global, open standard that gives mobile users access to Internet services through handheld devices. It enables users to easily access a whole range of Mobile Internet and other data services from mobile devices such as smart phones and communicators, without the need to plug into a separate Laptop or data-enabled device.
In wireless connectivity, mobile computing devices found a great way to connect with other devices on the network. In fact, this has been a great source of confusion between wireless communications and mobile computing. Mobile computer devices need not be wireless; laptop computers, calculators, electronic watches, and many other devices are all mobile computing devices, but none of them use any sort of wireless communication to connect to a network.
Mobile computing is no longer a technology trend, but rather, an integral component of our business and social lives. Already, 83% of Americans own mobile phones and tablet PCs are expected to reach one-third of U.S. adults by 2015, thanks to a remarkable compounded annual growth rate of 51%. The market’s message is obvious – people want anytime, anywhere access to data and documents.
There are three subgroups of the mobile worker: the office-based mobile worker, who spends most of his or her time in a company-provided office, but who also sometimes works at home or in a third place; the non-office-based mobile worker, who is in the field, such as a salesperson, or working between buildings on a corporate campus, such as an IT professional; the home-based mobile worker – formerly called a “telecommuter,” this employee spends most of the work week in a home office, but comes into the corporate workplace for meetings or collaborative work sessions.
Where technology is fundamental, it is not the driver of the change – it is an enabler that, properly planned and directed, is capable of making a substantial contribution to improved productivity and efficiency savings. Mobile computing, for example, can underpin flexible working practices that lead directly to performance improvement. This is particularly true when roles are carefully examined and technology is selected to match.
"In our bring-your-own-device work culture, people are using their smartphones for both personal and business use, and attacks on these devices are on the rise. This dynamic is changing the way corporations think about protecting their confidential data and intellectual property," Bit9 CTO Harry Sverdlove said in a statement.
Technology and data consumption are evolving faster than mobile networks are able to adapt; what we at iPass are calling “Mobile Darwinism.” The survivors of this evolution will be those who are able to quickly and continually adjust to change. Adaptation will not only be required by the network providers and device manufacturers – look at the decline of Palm and more recently Nokia and RIM/BlackBerry as examples of those who could not adapt – but by enterprise IT departments that rely on mobile services for their workforce.
Nearly three in four say they work more from home because of remote access and mobile telephones. Two in three feel this gives them a better work-life balance. Yet the number of people who feel this development is not to their benefit is growing, and the lack of a work-life balance is stress factor number one.
