Today, work is no longer confined to just the four walls of the office. Working away from the office has become the norm for field workers, offshore staff, sales and marketing personnel, managers, and even CEOs.

With the convergence and advances in information and communications technology (ICT), anyone can stay connected with their office from anywhere in the world. Wireless LAN is increasingly common and lots of products in the market provide users with wireless connectivity to an enterprise or corporate network. Users are given seamless connection to the Internet and the ability to access data anywhere, anytime without having to physically connect to a network access point.
