Telia Denmark

The company has provided 2G GSM services over the 900 and 1800 MHz bands since Julne 1997, and 3G UMTS3G UMTS: UMTS is an umbrella term for the third generation radio technologies developed by the 3GPP. UMTS specifies a complete network system, for which the radio access component, known as UTRAN, uses WCDMA technology to offer greater spectral efficiency and bandwidth to mobile network… 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. The network has since been shut down.

Telia was the first in Denmark to commercially activate its 4G LTE4G LTE: 4G LTE (Long Term Evolution) or the E-UTRAN (Evolved Universal Terrestrial Access Network), introduced in 3GPP Rel. 8, is the radio access component of the Evolved Packet System (EPS) - a purely IP based mobile network standard. As an evolution to 3G UMTS, 4G LTE shares many similarities, such as… 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 MIMO4x4 MIMO: A wireless communication configuration that uses four antennas, each capable of both transmission (the multiple inputs) and reception (the multiple outputs). This arrangement facilitates the simultaneous transmission and reception of up to four independent data streams over the same frequency band,… and 256QAM, reaching a 1 Gbps data rate milestone.

In June 2018 the company announced it would complete rollout of its national NB-IoTNB-IoT: Narrowband IoT (NB-IoT) is a 3GPP Release 13 feature that reuses various principles and building blocks of the LTE physical layer and higher protocol layers and defines a new Cat-NB1 UE. The standard leverages a mobile operator's existing LTE base stations permitting rapid time-to… network by end of year. Concurrently, Telia would deploy an LTE-MLTE-M: LTE-M is a type of LTE network published by 3GPP in Releases 13 to 15 specifications. LTE-M is a low power wide area technology which supports IoT through lower device complexity and provides extended coverage, leveraging a mobile operator's existing LTE base stations. LTE-M finds its… (Cat-M1M1: M1 Limited, commonly known as M1, is a telecommunications company based in Singapore. The company was founded in 1994, initially under the consortium name MobileOne. Its founding shareholders included notable entities such as Cable & Wireless plc, Hong Kong Telecom, Keppel Telecommunications, and…) network within its existing B20 (800 MHz) network.

Telia and technology partner NokiaNokia: Nokia Corporation is a Finnish company engaged in the network and Internet protocol (IP) infrastructure, software, and related services market. The Company's businesses include Nokia Networks and Nokia Technologies. The Company's segments include Ultra Broadband Networks, IP Networks and… 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.

The TT-Netværket infrastructure sharing agreement enabled Telenor and Telia to commercially launch their 5G network in June 2021 using n78 (3500 MHz) initially, but shortly after adding n3 (1800 MHz) in August.
