Ericsson and Swiss operator Swisscom have achieved another LTE Advanced world first in a live demonstration in Swisscom's commercial mobile network.

By introducing 256 QAM (quadrature amplitude modulation) in a combined three-carrier aggregation LTE FDD/TDD network, the partners achieved peak downlink speeds of over 426 Mbps, compared with 335 Mbps recently achieved with the same set-up in Swisscom's commercial network with current 64 QAM technology for downlink.

Ericsson and Swisscom have previously demonstrated Europe's first fully commercial LTE-Advanced three-carrier aggregation solution combining LTE in both FDD and TDD modes.

Patrick Weibel, Senior Architect Wireless Strategy, Swisscom, says: "At Swisscom, it is always our ambition to innovate to offer our customers the best network at all times. 256 QAM will add an important feature to the modernization of our LTE-Advanced network by increasing data speeds up to 30 percent without using any additional spectrum."

For the demonstration, held in Zurich, Switzerland, 256 QAM was introduced using software from the recently announced Ericsson Networks Software 16A, which will become commercially available later in 2015. The three-carrier aggregation solution in Swisscom's live commercial network makes use of two LTE TDD carriers, each with 20MHz bandwidth in the 2.6 GHz frequency band (B41), and one LTE FDD carrier with 15 MHz in the 2.1 GHz band (B1).

Per Narvinger, Head of LTE, Ericsson, says: "Ericsson Networks Software 16A introduces numerous features that help operators take important steps towards improved app coverage in the Networked Society. One of these features, 256 QAM modulation, significantly improves data throughput in any given LTE spectrum. We are proud to provide our partner Swisscom with another world-first innovation."
