TT-Network, Nokia Networks complete world's first shared GSM, 3G and LTE radio network

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.

Johan Wickman, CEO at TT-Network, said: "So far, no other operator has accomplished a multiradio sharing initiative of such a broad scope. In Nokia Networks, we have a trusted partner with global experience in shared networks that helped us achieve our aim of delivering high-quality services in Denmark."


Louise Suhr, head of TTN customer team at Nokia Networks, said: "Our unique solution and ability to manage complex network sharing projects allowed TTN to create Denmark's best mobile network more rapidly and more efficiently than either partner could have done on its own. The company now provides markedly improved mobile broadband services."

Nokia Networks has been at the forefront of network sharing by supplying the first commercial as well as the largest actively shared network worldwide. It is a preferred partner for most of the commercially shared networks existing today, building on more than 10 years of experience in implementing and managing these.
