Vodafone Portugal has claimed that it is ‘the first operator in Europe’ to achieve downlink transmission speeds of 600Mbps on its mobile network, using Long Term Evolution-Advanced (LTE-A) technology. The 600Mbps rate was achieved using the bandwidth of three different 20MHz spectrum blocks and aggregated using 256QAM equipment. The tests were performed in a laboratory environment, in partnership with Ericsson and Qualcomm Technologies.
As previously reported by TeleGeography’s CommsUpdate, in June the three companies revealed plans to add time division duplex (TDD) LTE capability to Vodafone’s already installed frequency division duplex (FDD) network. At that juncture the trio intended to utilise 15MHz of Band 3 spectrum (FDD-1800) alongside a 20MHz block of Band 38 spectrum (TDD-2600); it remains unclear as to which other spectrum band the companies used in the most recent trial.
