If the regulator Ofcom thought that dealing with Vodafone and O2 over sharing the spectrum was difficult, it looks as if this task is about to get a lot more tricky, with the merging of Orange and T Mobile.
According to the parent companies, Deutsche Telekom and France Telecom, when the merger between Orange and T Mobile is completed they have no intention of sharing access to their spectrum with rival mobile providers.
With the merger complete, the new entity will own 170 MHz of the available spectrum, whereas recently it has been suggested that there should be a cap of 120 MHz.
Of course, as Orange and T Mobile will be keeping their branding it could be argued that no one provider has over 120 MKz.
Nevertheless, this is still a problem for Ofcom.
