Ericsson and Telstra held a demonstration of 1 Gbps capability with five-carrier LTE-Advanced Carrier Aggregation integrated on a live mobile network. Downlink speeds in excess of 950 Mbps were achieved with a User Datagram Protocol speed test application by aggregating 100 MHz of spectrum across Telstra’s spectrum holdings. The companies were also able to hit download speeds of over 843 Mbps over the internet to the Speedtest.net site.
Reaching speeds of 1 Gbps was an original goal of the LTE standard. In the test, downlink speeds were achieved by aggregating 100 MHz of spectrum across the 700 MHz, 1800 MHz, 2100 MHz and 2600 MHz (2 x 20 MHz) bands and delivered to a Cobham Aeroflex TM500 mobile device. The aggregation of 100 MHz of spectrum using five carriers across four separate bands, as achieved in this test, lays the groundwork for the aggregation of higher frequency bands on the road to 5G, Ericsson said.
