As Ofcom announces details of the 4G mobile spectrum auction — the largest ever sale of mobile airwaves in the UK - we looked at what we should expect from 4G

4G services should make it much quicker to surf the web on mobiles — speeds will be nearer to what is currently experienced with home broadband.

Because of this, 4G is ideally suited for high-bandwidth data services such as streaming high-quality video, watching live TV and downloading large files.

For the typical user, download speeds of initial 4G networks could be around 5-7 times those for existing 3G networks. This means a music album taking 20 minutes to download on a 3G phone and just over three minutes on 4G. This is based on existing 3G speeds being 1 Mbit/s on average and 4G speed being 6 Mbit/s (on average between 5 and 7 times faster).
