Re: signal box on EE
Correct. The box is developed by Ubiquisys. However it is sold to operators through their systems integrators, NEC and Nokia Siemens, who already have a foothold in the operators core networks.
The same basic 'G3' box is used for SFR, Three and EE (T-Mobile and Orange). They just connect to their respective core networks, and potentially have different software loads on them.
