Tele2, Ericsson boosts data speeds by 60% with inter-site CA

Tele2 and Ericsson have successfully piloted inter-site carrier aggregation (CA) at 800MHz and 2600MHz, increasing data speeds by 60%.

The pilot launch, with two neighbouring base stations, increased data rates by 60% in a test segment on two frequency bands of the Tele2 LTE network in Moscow. A total 15MHz of bandwidth, using 5MHz and 10MHz of spectrum at 800MHz and 2600MHz respectively, was showcased.

“A growing popularity of online services is inciting operators to look for spectrally efficient solutions that would prepare the network for high loading and guarantee a perfect quality of connections,” said Ritvars Krievs, technical officer at Tele2. 

“Independent experts recognised Tele2 leadership in data rates in Moscow Region several times and the company is seeking to maintain this status in rapidly changing technological environment – in a new LTE ecosystem. Inter-site carrier aggregation allows to implement this task and make best use of frequency bands. The 2600MHz band provides more capacity and higher data rates, and 800MHz spectrum allows wider coverage.”

CA supports LTE-Advanced technologies by increasing peak and practical data rates, enhancing network capacity, simplifying traffic management and improving the downlink coverage.

Zoran Lukovic, vice president at Ericsson Russia, added: “Inter-site carrier aggregation is another next step in LTE evolution, it refers to LTE-Advanced technologies. Tests have proved efficiency of the technology and its readiness to be launched on the LTE network. It is supported by LTE devices of Cat4 and above, further evolution of the LTE-A ecosystem may lead to a wider use of the solution in Russia.”
