Tele2 Estonia CTO targets 300Mb/s LTE; rules out tri-band CA

Ervins Kampans (pictured), CTO at Tele2 Estonia, is targeting theoretical peak download LTE speeds of up to 300Mb/s this year, but will not be following the three-band carrier aggregation (CA) route favoured by SK Telecom and LG Uplus in South Korea.

Tele2 Estonia has enough spectrum resources to opt for three-band carrier aggregation across 800MHz, 1.8GHz and 2.6GHz, but Kampans told Mobile World Live he had not  thought seriously about the technology because it’s so nascent.

However, he doesn’t rule out three-band CA once it matures.

Tele2 Estonia, using equipment from NSN, is instead debating whether or not to deploy 4×4 MIMO technology or two-band CA – 40MHz combined across 1.8GHz and 2.6GHz – to achieve its 300Mb/s target.

One of Kampans’ main concerns is when mobile devices capable of supporting higher speeds will become available. He’s hopeful they’ll come to market either end 2014 or beginning 2015.

Tele2 Estonia is currently deploying LTE at 2.6GHz and 1800MHz. Following on from its acquisition of 800MHz frequencies in January, however, Kampans said the LTE focus in 2014 would be to use the sub-1GHz spectrum to establish nationwide coverage.
