Company Overview

DNA is the third largest mobile network operator in Finland. The company was formed in 1999 as Finnet, a cooperative of 40 local telephone companies. These companies gradually transformed into the Group's mobile communication operations company, DNA Finland Ltd.

In 2001, DNA changed from a mobile communication operator into a major telecommunications company. The current DNA Group began operating on 1 July 2007, when DNA Plc's business operations merged with those of six telephone companies. Alongside its mobile communication business, the company obtained a strong fixed-network business, including voice, data, cable TV and security services for both households and companies.

The company provides 2G GSM services over 900 and 1800 MHz, and launched 3G UMTS services in February 2007 over the B1 (2100 MHz) band. Rural and regional service was extended in October 2008 with the activation of a B8 (900 MHz) 3G service. The network was upgraded to DC-HSPA+ in May 2011.

DNA commercially activated its 4G LTE network in December 2011 using B3 (1800 MHz) and B7 (2600 MHz) for inner urban areas. B20 (800 MHz) LTE was launched January 2014, and later B28 (700 MHz) in February 2017. DNA began conducting LTE-A trials in March 2015, achieving peak data rates up to 270 Mbps. LTE-A was commercially launched in May that year, providing a 300 Mbps network using 2C CA (B3+B7), and later 375 Mbps with 3C CA (B3+B7+B20). 

600 Mbps LTE-A Pro was debuted in May 2016 using 3C CA (B1+B3+B20) with 256QAM modulation. Peak data rates hit the 1 Gbps mark in May 2017 with the network receiving its first upgrades to 4X4 MIMO.

In August 2014 DNA and TeliaSonera announced a joint venture company (Suomen Yhteisverkko Oy) to build a joint 4G LTE network to cover Finland’s sparsely populated geographical area in the north and east. LTE B20 (10 + 10 MHz) is pooled by the networks to provide a high capacity long range network.


Rollout of DNA's NB-IoT network began May 2017, with first commercial usage reported in February 2018. DNA utilises Band 20 (800 MHz) as its primary NB-IoT network, reverting to B3 in areas without B20 coverage.


DNA remained comparatively quiet on its 5G development until May 2018 when it announced its network backbone was being upgraded in preparation of 5G. The first timeline was given in October 2018 when it disclosed that its 5G network would launch at the beginning of 2019. The company officially launched its 5G network in January 2019, using n78 (3500 MHz) spectrum awarded in the country's September 2018 auction - noting DNA secured a contiguous 130 MHz block, from 3670 to 3800 MHz.

DNA's 5G network was initially launched in Helsinki, with a pilot program also announced for Vantaa.

News & Developments

DNA's 4G network upgrades started in autumn 2018 in Turku have been completed. The entire 4G network in Turku has been upgraded to higher performance and 5G deployment capability. With upgrades, local 4G data rates have risen more than double.

DNA will open the 5G network in Helsinki at the turn of the year. In the first phase, the network covering the core areas will be expanded when terminal devices enter the market. DNA is also currently operating a fixed pilot for fixed 5G or Fixed Wireless Access technology in Vantaa. In addition, other 5G customer pilots will be launched in Finland during

DNA has won 5G frequency band in the Finnish Communications Regulatory Authority’s frequency auction. The 5G services will be provided from the beginning of next year, and they will enable connection speeds of over 1 gigabit per second (1Gbps) for DNA customers.

DNA and Ericsson are testing the capabilities of the 5G network in Kirkkonummi. The ongoing tests are a continuation of the 5G demo of February 2017. Their main goal is to test issues such as services enabled by 5G and the base-station-specific coverage area.

Critical equipment for the backbone network has already been upgraded and DNA’s backbone network speeds have been raised by multiples of 400 Gbit/s to a maximum of 1.2 Tbit/s. In addition, the minimum speeds of local area networks, i.e. regional networks, have been raised to meet the new and future requirements of the area in question.

The DNA 4G network has possessed regional readiness since spring 2017. In spring 2017, the NB-IoT underwent a pilot experiment in the Tampere region DNA 4G network. In the experiment, sensors by the Talotohtori cloud service provider Enermix were connected to a service that measured indoor air conditions in a retail store.

The new maximum speed is tested in collaboration with Ericsson in Karuby, Siuntio, the fastest 4G village in Finland, where the theoretical maximum network speed has now reached one gigabyte per second (1 Gbps). The theoretical maximum speed is also important because it reveals the base station’s total capacity and enables higher actual average speeds for mobile network users. 

DNA has taken another step toward 5G by testing a 1Gbps speed on its mobile network. At the same time, DNA ensures maximum speeds for all network users by continuing to increase the capacity of its national 4G mobile network. 

Tests have shown that the new NB-IoT (Narrow Band Internet of Things) technology makes it possible to connect an increasingly broad range of devices to the Internet. This means that broader selection of sensors and devices can be connected in the Internet in increasingly challenging locations to facilitate, for example, the monitoring of humidity and air quality in buildings.

The first base station using the new frequency range will begin operating in Somero and this will significantly improve local mobile broadband connections.
