Recently, SK Telecom, a 4G mobile service provider in Korea, has demonstrated 600 Mbps data transmission rate by using Nokia Networks’ MIMO technology.
To demonstrate the 600 Mbps data transmission speeds, SK Telecom and Nokia Networks first realized 300 Mbps data rates by applying 4X4 MIMO technology to a contiguous 20 MHz block of spectrum. Later they combined two of these wideband LTE bandwidths using Carrier Aggregation (CA) technology to achieve 600 Mbps LTE-Advanced data speeds.
UQ Communications, a WiMax operator in Japan, will begin offering 220 Mbps 4×4 MIMO capable commercial devices in March. WiMAX 2+ service is compatible with LTE TDD.
“High-performance features such as 4 by 4 MIMO and Carrier Aggregation, which we are deploying in cooperation with Ericsson, reflect our unwavering commitment to provide our customers with superior performance, value and support,” said Toshikazu Yokai, corporate officer, director of Technology Division, UQ Communications.
