Company Overview

Telia DK (Danmark) is the third largest mobile network operating in Denmark. The company was founded in 1995 as a result of a merger between Telia Stofa and TeliaSonera. Telia DK is a wholly owned subsidiary of Swedish-Finnish Telia Company.

A network sharing agreement between Telenor DK and Telia was forged in 2012, resulting in the establishment of a common infrastructure company (TT-Netværket P/S) to operate a joint radio access network.

The company has provided 2G GSM services over the 900 and 1800 MHz bands since Julne 1997, and 3G UMTS services over the B1 (2100 MHz) band since December 2007. A B8 (900 MHz) UMTS service was added in 2012 to improve regional coverage, and the network upgraded to support DC-HSPA+ in 2014.

Despite being the slowest mobile network operator to launch 3G services, Telia was the first in Denmark to commercially activate its 4G LTE network, launching a B7 (2600 MHz) service in December 2010 using a 20 MHz channel width. The service was extended further in October 2011 with the launch of a 10 MHz wide B3 (1800 MHz) carrier. Telia announced the upgrade to LTE-A in August 2015 with the switch-on of 2C carrier aggregation (CA_3A-7A) offering peak data rates of up to 300 Mbps.

Following the merging of Telenor and Telia's LTE networks, Telia also offers a 3C CA service which has been progressively deployed by TT-Netværket since 2016, using B3 (1800 MHz), B7 (2600 MHz), and B20 (800 MHz) bands.

In September 2018 the company announced the implementation of LTE-A Pro technologies 4X4 MIMO and 256QAM, reaching a 1 Gbps data rate milestone.

Telia Denmark IoT

In June 2018 the company announced it would complete rollout of its national NB-IoT network by end of year. Concurrently, Telia would deploy an LTE-M (Cat-M1) network within its existing B20 (800 MHz) network.

Telia Denmark 5G

Telia and technology partner Nokia have conducted 5G tests at the company's office in Copenhagen in August 2018. The first live network tests were announced in February 2019, again to be performed in partnership with Nokia.

News & Developments

Denmark will soon have its first life test of 5G - this is done with equipment from Nokia on Telenor's and Telia's common mobile network. Both Telenor and Telia have previously tested the mobile technology of the future and with the establishment of the new life test, the two telecom groups will be front runners compared to 5G here in Denmark.

Denmark is today rounding a technological milestone. For the first time, Danish mobile customers now have access to an internet speed that has rounded the magic limit of 1,000 Mbit / s. Initially, Telia has opened for 1,000 Mbit / s in Copenhagen. But more cities are on their way. However, it is still only a small handful of mobile phones that support such high speeds at all.

Over the past week, Telia has carried out a number of 5G demonstrations based on both end-to-end solutions and the upcoming 5G standards, which otherwise only come into force from 2020.

When Telia Denmark later on this year brings the Narrowband IoT (NB-IoT) technology to its entire network, Telia Company will become the first operator to deploy NB-IoT across the entire Nordics. The new technology, designed for the Internet of Things, makes it possible to easily connect a huge number of sensors directly to the mobile network.

Together with a number of selected corporate customers, Telia is busy testing a new high-tech mobile network to support the future Internet of Things (IoT). The test results are promising, and Telia expects to be in the air with a nationwide Narrowband IoT network before the end of 2018.

Copenhagen, Denmark - Telenor and Telia have signed a managed services contract with Nokia that will see the company manage their joint mobile radio network in Denmark. The agreement will allow Telia and Telenor to offer customers of Denmark's largest mobile network even better coverage and greater capacity for a world-class mobile experience.
