4G services are available in US cities, but although O2 has tested 4G here, commercial launches are unlikely until post-2012.
However, manufacturers are keen to push new phones and tablets packed with very high specifications and take advantage of the high-speed download speeds available on 4G networks.
Leading the fray is Motorola Mobility’s Atrix. Motorola's mobile division has now spun-off from the parent company and is planning a marketing push in the UK.
The Atrix can be best thought of as a fully functioning computer-as-phone and is packed with gadgets and features to create and edit documents and media on the go. Orange will carry the phone in the UK, due to launch in the second quarter of 2011.
Motorola Mobility has moved all its phones onto the Google Android operating system and is launching a second 4G phone called the Droid Bionic and a tablet, to be called the Xoom, which will be 4G compatible by the second quarter of 2011.
The first fully-functioning 4G tablet device will be Dell’s Streak 7, available in "a matter of weeks" through T-Mobile in the US, and, again, using Google’s Android operating system.
LG's G-Slate tablet will also be 4G-compatible, and will be run on the Android 3 platform, known as Honeycomb. LG signed Kelly Brook as brand ambassador for its Optimus One handphone in November.
Samsung's 4G LTE is believed to be a 4G variant on the Google-branded Nexus-S that launched last month. It will also release the 4G Galaxy S and was promted hard by the manufacturer at CES.
HTC, the manufacturer of the Windows 7 Phone, was also at the US event pushing its EVO Shift 4G smartphone.
