5GTN: A test network for 5G application development and testing

The 5th generation mobile networks (5G) bring a number of new possibilities for application developers. They cut down many barriers that have potentially prevented developing new applications for mobile networks by introducing significantly higher data rates, lower delays, and better energy efficiency. 5G is not only an evolution of radio technology. The basis of the 5G concept is built upon a strong emphasis on requirements of various applications and their use scenarios. To support application development for 5G networks, test networks are playing an essential role. This paper presents a 5G test network, which is developed and deployed in Oulu, Finland, together with a number of different partners closely involved in the development and specification of the 5G technology. The test network targets to serve various application developers by providing extensive test facilities in a carrier-grade state-of-the-art network.
