A deal has been struck between mobile broadband network provider O2 and telecoms giant BT which will see the maintenance and development of O2’s networks placed in the hands of its former owners.

You will have to cast your mind back nearly a decade to when O2 was known as BT Cellnet in order to see the links between the two firms in their entirety. It was in 2001 that O2 was born from a variety of subsidiaries of BT and later bought out by Spanish firm Telefonica in 2006.

Mobile phone and mobile broadband packages have always been O2’s main products, but after first offering home broadband and then proposing home telephone deals, O2 looked as though it would be competing directly with BT for the same audiences.

But relations between O2 and BT are clearly healthy, as the pair have just signed a five year contract that will be worth millions of pounds and will commit the BT Wholesale division to overhauling O2’s mobile broadband network.

Well publicised performance hitches with the current 3G network operated by O2 are likely to have prompted the inception of the partnership and the large volume of mobile data traffic that O2 has had to handle as a result of its growing iPhone user base is also a contributing factor.

O2’s Nigel Purdy said that the deal was indicative of O2’s desire to keep its networks and products relevant well into the future.

Simple Broadband’s Simon Gerrard added “O2 is clearly taking on board any criticisms that have been levelled at its mobile broadband service in recent times. With Orange mobile broadband free laptop deals making headlines and its rivals offering wider network coverage, O2 will really be looking to maximise its network capabilities in the future and BT will help to make that a reality.”
