Previously there was only really one practical broadband connection type, that of ADSL connections that go through the phone line. In the early days of broadband, mobile broadband was not very fast at all, and wasn’t very practical or accessible for many consumers. These days, ADSL is not the only good option, since cable, fibre optic and mobile broadband are viable alternatives for most users.
Mobile broadband is increasingly popular as a primary means of accessing the internet. The main difference between mobile broadband and other types is that cable, ADSL and fibre rely on a physical connection to the users home, while mobile broadband can be transmitted over the mobile phone networks wirelessly from phone towers. In this way it operates similar to the normal signal you get on your mobile phone.
Nearly all mobile devices (tablets and phones) are equipped to receive this mobile internet signal with built-in receivers, while computers can be enabled to pick up the signal with the aid of a dongle or MiFi router, a USB stick, a PC card, or can have technology built-in similar to phones.
In terms of the actual signal picked up, there is also a difference between 3G and 4G, with 4G being faster. Which you can pick up will depend on your device and network, as well as your location.
Mobile broadband can be cheaper depending on your usage, easier to set up, much more flexible, and certainly faster than dial-up. It can also be bundled with your phone service since all major phone networks offer mobile broadband.
