Ericsson and telecommunications operator Cosmote Greece have demonstrated download speeds of 500Mbps in a live LTE network in what they claim is a carrier aggregation first for Europe.
Cosmote is aiming to deploy FDD 3 x carrier aggregation and 256 QAM technology into its commercial network with the aim of boosting performance and helping it to differentiate itself in the market.
The demonstration, which took place at the Infocom World 2015 event in Athens on 24November 2015, used Ericsson’s radio solutions and Networks Software 16A . In addition, three component 20+20+10MHz FDD LTE carrier aggregation in combination with 256 QAM modulation was deployed in a live network for the first time in the European market.
LTE Advanced carrier aggregation technology supports the use of multiple LTE carriers in a single LTE network. By increasing network bandwidth, carrier aggregation delivers higher peak data rates and better user experiences across the network coverage area.
Ericsson said its 256QAM downlink encoding technology provides up to 33% higher downlink throughput in good radio conditions. This enables more efficient use of the spectrum allocated to a cell, as well as a 33% increase in maximum user downlink throughput.
