South Korea’s largest cellco by subscribers SK Telecom (SKT) has reportedly confirmed that it has begun rolling out more base stations which will use its 10MHz in the 2100MHz band for Long Term Evolution (LTE) in certain areas of Seoul, Gwangju and Busan. According to Light Reading, with the mobile network operator having trialled LTE over the band in question back in February this year, the construction of the new cell sites is seen as a pre-cursor to SKT’s introduction of 3band LTE-Advanced (LTE-A).
As previously reported by CommsUpdate, in February 2014 SKT revealed that it had been granted regulatory approval to use 10MHz in the 2100MHz band for LTE-based services which it acquired in a 2010 auction. At that date the company said it would begin construction of 2100MHz LTE base stations in the second quarter of 2014, with SKT saying it aimed to make the network available for commercialisation ‘as soon as the supporting handsets come to market’. While chipsets that support speeds of up to 300Mbps are still being developed, the operator also said it would apply multi-carrier technology to the 2100MHz base stations with a view to relieving the burden on its existing LTE infrastructure.
