Tele2 Russia and Ericsson have piloted inter-site carrier aggregation (CA) on two neighbouring base stations in Tele2’s Moscow network, increasing data speeds by 60% using 5MHz and 10MHz of frequencies in the 800MHz and 2600MHz bands, respectively. Zoran Lukovic, vice president of Ericsson Russia, said: ‘Inter-site carrier aggregation is another next step in LTE evolution … 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.’ Ritvars Krievs, Tele2 Russia’s technical officer, added: ‘Inter-site carrier aggregation allows … best use of frequency bands. The 2600MHz band provides more capacity and higher data rates, and 800MHz spectrum allows wider coverage.’
Also in Russia, Mobile TeleSystems (MTS) and Nokia have completed testing of Narrow Band Internet of Things (NB-IoT) technology on MTS’ LTE-1800 network in Moscow. The LTE network segment used for the test included a virtualised core and cloud platform for the management of IoT devices, as well as open interfaces for user applications. MTS said the system will enable users to automate a broad range of production and business processes supported in the operator’s existing machine-to-machine (M2M) product portfolio, and it plans to start marketing NB-IoT-based solutions to its corporate customers in the first half of 2017.
