TT-Network (TTN), the joint venture between TeliaSonera and Telenor, has completed the final phase of its groundbreaking Single RAN network sharing project, for which Nokia Networks was the sole radio and services provider. This is the first time ever that a network across GSM, 3G and LTE has been supplied to two operators sharing the network and frequencies. It has led to improved coverage and capacity along with an excellent mobile broadband experience.

TTN’s process for creating a common infrastructure in Denmark started in 2012 with the merger of Telia’s and Telenor’s LTE networks, followed by 3G. Now the company has finalized the consolidation of the GSM portion.

To combine the two live-traffic nationwide networks, the operation – carried out across multiple technologies and frequencies in a multi-vendor core network environment – was planned in minute detail and performed so that there was no disruption to subscribers.
