Orange and Ericsson have successfully completed the world’s first live LTE-Advanced FDD trial

Orange and Ericsson have successfully used the 3.4-3.6 GHz (3.5 GHz) frequencies for testing data speeds, coverage and FDD carrier aggregation. This live LTE-Advanced FDD trial, which was authorized by the French regulator ARCEP, was carried out in October-November 2014 on Orange’s network in Bordeaux using Ericsson’s pre-commercial equipment.

The first phase of the trial was performed at the Orange Labs in Paris. In this trial, speeds of 300 Mbps were achieved by using the 3.5 GHz band in aggregation with the 2.6 GHz band, thereby confirming the potential of 3.5 GHz FDD technology to increase mobile broadband capacity. The second phase was carried out on Orange’s live mobile network and was based on Ericsson’s pre-commercial FDD 3.5 GHz radio base station equipment.

For the trial, new antennas supporting the 3.5 GHz band were installed at the Le Ponant and Meriadeck sites in the city center of Bordeaux. A range of streaming-based services were tested allowing the team to continuously monitor network performance between the base station and the mobile prototype throughout the live trial. The data throughputs acquired during the tests were measured, both before and after carrier aggregation of the two bands. A peak performance of 150 Mbps at a distance of up to 700 meters was achieved in the 3.5 GHz band when used alone, and speeds of 300 Mbps was attained when used in aggregation with the 2.6 GHz band.
