Asia’s TD-LTE Advanced tests blow standard LTE away

Recently Asia started launching their next generation TD-LTE Advanced network and Signals Research Group got to test drive TD-LTE in Tokyo and LTE Advanced in Seoul. On Softbank’s TD-LTE network in Japan they achieved a peak download rate of 92.3Mbps and 141 Mbps on an LTE advanced carrier aggregated network by a South Korean mobile carrier. Both LG U+ and Korea Telecom have launched LTE advanced carrier aggregation which allows carriers to take advantage of multiple cellular channels to help improve download and upload speed. For example, if Verizon or AT&T decided to use carrier aggregation you’d basically double your current throughput. To put these speeds in perspective Verizon, AT&T and Sprint are averaging around 5-15Mbps download and 2-5Mbps upload over the current LTE networks with customers seeing bursts into the 30-40Mbps range.
