There's nothing worse than working on the go, from a hotel room or airport for example, to find there's no Wi-Fi internet access, or it's so rubbish it keeps dropping out. Alternatively, what happens if your ISP serving your home network goes down and leaves you without access to the web?
If you've got a smartphone then it's possible to turn your handset into a portable Wi-Fi hotspot using your device's 3G connection to access the web, a process that's called 'tethering'. In the case of Google Android handsets, the search introduced the feature when it unveiled Froyo, version 2.2 of its Android operating software. Those with smartphones running Google Android 2.1 or lower, you'll need to download an app such as PDANet or Easy Tether.
It's worth remembering to check your network's terms and conditions on tethering and keep an eye on your data allowance as depending on your web activities you could find yourself hitting your mobile data cap a lot quicker than you think. Exceeding your data limit may result in an unwanted charge.
