Mobile broadband: Mobile broadband allows devices such as smart phones, laptops and netbooks to connect to a high speed internet connection over a wide geographical area, without the need for wires. Mobile broadband relies on the 3G network. (4G is currently becoming more and more widely available). Users can access the internet virtually anywhere that there is a mobile phone signal. Smart phones have 3G capability built in Laptops can be connected using a 3G dongle

Advantages: Disadvantages: Those who use the internet for work are not restricted to using it only at home or the office. No landline or cable is needed to use the internet. More secure than Wi-Fi as the data is encrypted. Can act as a backup if your home broadband goes down. Disadvantages: In some places there is weak or no 3G reception. Can be expensive if you go over your data limit. Expensive roaming charges if used abroad. Could lead to stress if continually working outside of work hours.

Scenarios: Consider the following scenarios and decide whether or not mobile broadband is a good option. Give reasons for your answers Scenario Is mobile broadband a good option? Why? A woman selling handmade cards from home No, could lead to stress if continually working outside of work hours Students living in temporary accommodation Not really, can be expensive if you go over your data limit which students cannot afford. A business woman who travels to other countries regularly as part of her job No, expensive roaming charges if used abroad.
