As 3G finally takes off is the world quite ready for 4G?

Just as the mobile world is getting used to the benefits of 3G a group of leading mobile network operators is discussing a possible move towards 4G.

The group includes Sprint Nextel, T-Mobile, KPN Mobile, Orange and Vodafone and is attempting to create a set of standards for 4G to follow when it is developed. The Next Generation Mobile Networks group intends to produce recommendations for the creation of 4G networks when they arrive in around 5 years time.

The group, who will be based in the UK, will be looking into a packet switched network to allow existing 2G & 3G services to be moved across to a 4G architecture without major problems.

At present the major developments in 3G are focused on increasing bandwidth and using HSDPA to increase download speed. Most operators are also experimenting with mobile TV and receiving signals from the existing television stations.
