What is Mobile Computing?

Mobile computing is a form of human–computer interaction by which a computer is expected to be transported during normal usage.

Mobile laptop and notebook computers can use one of two types of wireless access services when away from the home or office. The most commonly used and least expensive is WiFi®. WiFi uses radio waves to broadcast an Internet signal from a wireless router to the immediate surrounding area. If the wireless network is not encrypted, anyone can jump on. WiFi is commonly used in public places to create “hotspots.”

Another service associated with mobile computing is cloud computing, or the ability to use website services from mobile computers. Cloud computing provides access to a network-like environment with various applications and virtually unlimited resources so that field representatives, for instance, can utilize website resources rather than being supplied with weighty, expensive machines packed with company software and data. Mobile computing also provides access to a company’s virtual private network (VPN) by tunneling through the Internet. It’s nearly impossible to estimate the value of increased business productivity afforded by mobile computing.

Cellular broadband is also used for providing Internet access to cell phones and PDAs. Access is usually considered a premium service that either increases the monthly cost of the plan associated with the device, or incurs extra fees when used. In some cases, restricted Internet access is allowed for free when connecting to the carrier’s website to manage an account, for example, or to purchase products from the carrier such as custom ringers or wallpaper.
