Ericsson and Turkcell demonstrated 3-carrier High-Speed Downlink Packet Access (3C-HSDPA) with a top speed of 63 Mbps. The demo was carried out in the 2.1GHz band in a WCDMA commercial network using three 5 MHz carriers for downlink and two 5MHz carriers for uplink, which were all within the 2.1GHz frequency band that is owned by Turkcell. The demo used Enhanced Uplink Multi-carrier (EUL-MC) to achieve an 11.5 Mbps uplink. The trial used core network and radio access network nodes supplied by Ericsson.
The test utilized a feature that will be included in Ericsson's software release 15A and was conducted on a smartphone powered by a Qualcomm processor with its integrated Qualcomm modem.
Turkcell currently operates a Dual-Carrier HSDPA network supporting speeds of up to 43.2 Mbps in downlink and 5.76 Mbps in uplink.
Bulent Elonu, Chief Network Technology Officer, Turkcell, says, "At Turkcell, Turkey's leading telecommunications and technology company, we are following global advancements closely to provide the latest technology to our customers as quickly as possible and to ensure excellent customer experience. We have been following three carrier development plans as the next step from two carrier technology for a long time. In the past, we have offered our customers a number of innovative solutions with Ericsson and Qualcomm Technologies. Today, this successful demonstration enabled us to introduce another groundbreaking innovation. Data download using three carrier has been tested for the first time on a network globally. We are proud that Turkcell has successfully hosted the first global testing of this promising future technology."
