Have you ever been out of the office and need to make a last minute change to a spreadsheet or presentation? In a perfect world, our smart phone would support Microsoft Office and it would be easy to do a last minute update. Reality is not this simple though; for starters, you might not have WiFi in the vicinity to gain access to the office database, and trying to navigate a spreadsheet on a 4cm screen while zooming in can be challenging.
“Tethering” is a way to bring the best of both worlds together – the ubiquity of 3G service with the comfort of larger screens on laptops. Tethering is the use of an Internet-enabled mobile device as a modem for another device. It enables users to go online from their laptop while on the road when there is no other means of Internet access.
