TDC (YouSee) is the largest mobile network operator in Denmark. With a history extending back to 1882, the company (then Kjøbenhavns Telefon Aktieselskab) is the country's incumbent telecommunications service provider. Operating under the brand Tele Danmark since the early 1990s, the company changed name to TDC in December 2000. TDC Group is a publicly traded company on the Copenhagen Stock Exchange, with majority stock held by a conglomerate of private equity firms.
The company has provided 2G GSM services over the 900 and 1800 MHz bands since July 1992, and 3G UMTS services over the B1 (2100 MHz) band since May 2007. The network was upgraded to support HSPA+ in May 2010, and DC-HSPA+ in March 2011. An additional B8 (900 MHz) service was launched in 2014.
4G LTE was commercially launched in October 2011, initially over the B7 (2600 MHz) band, and later B20 (800 MHz) in early 2013. July 2015 saw the activation of LTE-A, with the network advertising peak data rates of 300 Mbps using 2C carrier aggregation (B7+B20). The network was upgraded to 3C CA, adding an additional B3 (1800 MHz) service to the mix.
4.5G LTE-A Pro was demonstrated December 2016 ahead of its early 2017 launch, where the network exceeded 1 Gbps using 4X4 MIMO and 256QAM.
TDC has been trialling NB-IoT since early 2017, and announced in February 2018 that it was in the process of deploying the service nationwide over a 200 kHz channel in its B20 (800 MHz) guardband.
The company announced successful 5G trials in May 2018, achieving 1.9 Gbps using a 100 MHz channel in the n78 (3500 MHz) band.
