Danish cellco Hi3G has upgraded 142 towers in the central parts of Copenhagen and Aarhus to support Long Term Evolution Advanced (LTE-A) technology. The operator is using Carrier Aggregation (CA) in the 1800MHz and 2600MHz frequency bands to deliver maximum download speeds of 150Mbps over the network. Despite trialling the technology in June 2014 at the company’s headquarters in Copenhagen, Hi3G said that LTE-A has not been introduced commercially in Denmark due to lack of handset support. However, following the commercial introduction of Samsung’s Galaxy Alpha handset and Huawei’s E5186s-22a 4G router, the service is now available to potential customers.
Kim Christensen, director of 3 Networks department, said: ’It is exciting that we now see the hardware on the market that can leverage the technology that we quietly put on top of our existing 4G LTE network. For us it is important to utilise our spectrum optimally in order to meet the growing demand from the many Danes who have subscribed to the popular streaming services.’ Going forward, the operator is planning to upgrade ‘a number of masts’ in 2015.
