Nokia to upgrade core networks for three United Group subsidiaries

11 Aug 2021

United Group has awarded Nokia a contract to upgrade its core mobile networks in Bulgaria, Croatia and Slovenia. The Finnish vendor replaces two legacy equipment suppliers to become United Group’s sole core network partner in the three markets. Nokia will provide products including Cloud Packet Core, Voice Core, 3G Core and Cloud Infrastructure, as well as its Subscriber Data Management (SDM) software. The core deployments will be rolled out initially for the Group’s 3G and 4G networks on the cloud, via Nokia’s cloud infrastructure, starting by the third quarter of this year. United Group will then roll out 5G non-standalone (NSA) and standalone (SA) services.

Earlier this year, Nokia announced that it will deploy a fibre network and in-home mesh Wi-Fi solution across the eight European countries where United Group operates.

Zeljko Batistic, Chief Technology Officer at United Group, said: ‘The surge in connected devices and all the demands that mobile users have today require a powerful wireless network that can transfer large volumes of data fast, securely and with very low latency … The investments we are making – in both mobile and fixed – will guarantee that United Group’s users always have access to the very best our industry has to offer.’
