3g laptops explained

3g laptops allow you the freedom of mobile 3g broadband on your laptop. We show you what to look out for in 3g laptops.

Not so long ago, laptops needed a separate card to connect to the internet. This was a chunky piece of plastic that plugged into the PCMCIA slot on the side of your laptop and gave you a connection to either wireless or 3G internet.

As wireless became better and more popular, wireless internet cards were built in to laptops to remove the need for the separate hardware. All modern laptops have a built in wireless internet card, so you'll just press a "Wireless ON" button, and all the networks in range show up in your network list. If you have the password, off you go!

Built-in wireless - 3g laptops

The demand for mobile internet has brought about another stage in laptop evolution: some laptops now have USB mobile broadband technology built in, giving you 3g laptops, or even 4g in some cases. This means that the technology from a USB dongle is mounted inside your laptop, so you always have a 3G or even 4G mobile connection available.

  • Wire-free internet access wherever there is a mobile phone signal
  • 3G or 4G access so no wireless network needed
  • Internet connectivity direct from your laptop - no dongles or modems!
  • All-in-one portable high-speed broadband access

Everything is integrated - no more losing things! 3g laptops are 100 per cent portable - your internet connection moves with you. Cheap - especially if you haggle with your mobile operator for better data charges!

3G's average speed of 3.6Mbps and an absolute max of 21Mbps - not quite enough for the most demanding users. Low monthly data allowances - not for the heavy user either. 3G is good but it's not the fastest any more - 4G is already replacing it, but isn't cheap. Coverage is limited - like your mobile, you'll need a phone mast nearby.

Data allowances

Data is probably the biggest decider, and the small data rates don't make USB internet the ideal choice for home connections.

How does it work?

The 3G or 4G SIM card and software are pre-installed on the laptop, so when you turn it on it's all ready to go. Built-in mobile broadband laptops use:

  • High Speed Mobile Broadband (HSDPA)
  • 3G
  • GPRS networks

This means that when you are using a laptop or notebook with in-built broadband, you can rest assured that you are getting the fastest possible mobile connection.

You are not always online even if you have a laptop with built-in mobile broadband. Almost all notebooks and laptops with in-built mobile broadband have one-click access to the internet.

Built-in broadband laptops have been optimised for mobile broadband access. This means that in-built mobile broadband laptops will generally have improved battery life.

Which providers offer laptops with built-in mobile broadband?

Broadband laptops used to be available from a host of providers, but these offers have entirely disappeared in recent years and have been replaced by broadband tablet deals. This reflects a wider shift in consumers' buying habits, as slates replace laptops as the mobile computer for most people.
