Why Use Wi-Fi When You Can Use 3G?

Wi-Fi and 3G are both methods of going online wirelessly, but which is better? Today most cellphones, smart phones, tablet computers and laptops have the capability to use both or either, so which should you use?

Wi-Fi

• A Wi-Fi-capable cellphone, laptop, netbook or iPod can connect to a Wi-Fi network, either at your home or in places such as a bar, cafe or library. Obviously the downside of this is that you have to find a Wi-Fi network you can use. Most networks are password protected and some cafes charge for Wi-Fi usage. However, if the signal is strong, a Wi-Fi connection often runs faster than a 3G signal.

3G

• 3G is a mobile telecommunications network providing wireless Internet access, video calls and telephone services. 3G is available on a variety of contracts, as well as on a number of "Pay As You Go" deals.

Wi-fi or 3G?

• If you're a heavy online user who travels around a great deal on business and spends a lot of time working on trains and planes, it makes sense to go with a 3G contract. However, bear in mind that all telecommunications signals can be erratic and have "blind spots" in which they lose a signal. If you work from home or know of a place where there is network you can use, you should stick with Wi-Fi.
