Ericsson and China Mobile Hong Kong demonstrate FDD/TDD 3CC Carrier Aggregation in Live Converged LTE Network
- The aggregation of three-component carriers in live China Mobile Hong Kong’s converged LTE-A FDD/TDD network achieved 272 Mbps download speed
- Ericsson’s LTE-Advanced FDD/TDD carrier aggregation effectively maximizes spectral efficiency, enhances app coverage and improves user experience
Ericsson (NASDAQ:ERIC) and China Mobile Hong Kong successfully completed the live demonstration of LTE-Advanced FDD/TDD three-component carrier (3CC) carrier aggregation and achieved a peak download speed of 272 Mbps.
The demonstration was performed on China Mobile Hong Kong’s network using Ericsson FDD+TDD carrier aggregation technology and TM500 network testers supplied by Cobham Wireless. In the demonstration, one 15 MHz LTE FDD carrier in 2.6 GHz band was aggregated with two LTE TDD carriers in 2.3 GHz band (one 20 MHz and one 10 MHz carrier) via carrier aggregation technology.
China Mobile Hong Kong pioneered the launch of the world’s first LTE FDD/TD-LTE converged network powered by Ericsson in 2012. Following this, today’s demonstration is another technological accomplishment.
Dr. Ma Zibin, Director and Vice President, China Mobile Hong Kong, said: “We have just achieved another milestone for the converged LTE FDD/TD-LTE network and see it as a huge development for the future needs of the services supplied by telecoms to their customers. China Mobile Hong Kong pioneered the world’s first LTE FDD/TD-LTE converged network in 2012 and we continue our commitment by demonstrating the advantages of LTE-A FDD/TDD 3CC carrier aggregation in a live network. We believe this technology will become a milestone in the development of telecoms networks.”
Paul Bergström, President of Ericsson Hong Kong & Macau, says: “Ericsson 2015 Mobility Report shows that smartphone data is predicted to increase ten-fold by 2020. To cater for the increasing demand while at the same time ensuring the best user experience, mobile operators require a solution to make the most efficient use of spectrum resources. Our LTE-Advanced carrier aggregation is a key technology enabler. Ericsson demonstrated 450 Mbps download speed achieved by combining three 20 MHz LTE carriers last year. Today’s demonstration is completed in a different environment -- on a live converged LTE FDD/TDD network.”
Carrier aggregation is an LTE-Advanced technology that increases bandwidth and thereby increases peak data rates. Carrier aggregation is supported in both modes of LTE, namely the FDD and TDD variants. This ensures that both LTE FDD and LTE TDD are able to meet the high data throughput requirements placed upon them. Each aggregated carrier is referred to as a component carrier.
Ericsson is present today in all high-traffic LTE markets including the US, Japan and South Korea, and is ranked first for handling the most global LTE traffic -- 40 percent of the world's mobile traffic is carried over Ericsson networks, which is twice as much mobile traffic as the closest competitor. Ericsson is number one in LTE market share within the world’s top 100 cities. More than 220 LTE RAN and Evolved Packet Core networks have been delivered worldwide, of which 170 are live commercially.
