Mobile data usage has increased by more than 1,800% in the past two years, fuelled largely by the iPhone and subsequent SmartPhones in conjunction with mobile operators unlimited data tariffs. Whilst the end of the unlimited data tariff is nigh, the thirst for mobile data remains unquenched and the continual rise in its usage will cause the mobile networks to reach capacity without action being taken.

Reducing the data limits on tariffs will certainly have an impact, but will it be enough to solve the problem? That's unlikely and other methods will have to be employed to get traffic reductions that are necessary to avoid the slowing down or crashing of traffic.

One of the options being looked into is cognitive radio, whilst another is the usage of spectrum previously used for other services. As the UK goes digital for its TV services frequencies are left behind which could be used for data traffic. Ofcom has also explored how enabling phones to switch between service providers to find the strongest signal could be a solution in some areas where signal quality is particularly poor. 

The mobile networks are currently opposing plans to dish out extra spectrum as it is not clear how it would be done and whether they may end up losing out financially as a result. However, one thing is clear, there will soon be a genuine need to reduce data traffic on the networks in order to keep it flowing smoothly and provide a good service for the majority of users.

As technology advances and wi-fi becomes standard on all new phones this means of data transfer may be encouraged by the networks. It is also worth mentioning again that wi-fi usage generally does not come out of your tariff meaning that is free of charge to the end user. You don't have to worry about data tariffs or fair usage policies!
