Next-generation mobile networks in Asia are performing impressively out of the gate, but their success reflects network design as much as air interface achievements, according to Signals Research Group, which recently drive tested TD-LTE in Tokyo and LTE Advanced over an FDD network in Seoul.




The company achieved a peak downlink data rate of 92.3 Mbps on SoftBank's TD-LTE network in Japan. Even more impressive was the blazing peak downlink data rate of 141.0 Mbps on an LTE Advanced carrier aggregated network operated by an unspecified South Korean mobile carrier. SK Telecom, LG U+ and Korea Telecom have all launched LTE Advanced carrier aggregation.





Signals Research tested SoftBank's TD-LTE and LTE FDD networks in Japan using two test USIMs supplied by the operator and access to a high-bandwidth FTP server that was used for testing purposes. The research firm also used a Qualcomm (NASDAQ:QCOM) test platform with a form factor comparable to that of a commercial device.


SoftBank has deployed a 1 x 20 MHz channel of TD-LTE in Band 41, where the center frequency is 2565 MHz. "We observed an average downlink data rate of 31.3 Mbps and a peak downlink data rate of 92.3 Mbps in the SoftBank LTE TDD network while concurrently testing the operator's FDD network," Thelander said.


Signals Research tested LTE Advanced Release 10 carrier aggregation in Seoul, leveraging 2 x 10 MHz carriers with multiple devices. The firm also had access to a high-bandwidth FTP server in the country and augmented that server with a second FTP server located outside of the country and a UDP server located in North America.


In Seoul, the company bought an LG G2 smartphone that supports carrier aggregation and an LG Optimus smartphone that was limited to LTE Release 8 capabilities. Both smartphones came with service contracts. The research firm also rented two LTE smartphones to take advantage of the USIMs, which offered unlimited daily usage.


Signals Research recorded an average downlink data rate of 62.0 Mbps and a peak downlink data rate of 141.0 Mbps during the LTE Advanced carrier aggregation testing in Seoul.


"Based on our preliminary analysis and observations while collecting the data, we believe that both networks are capable of achieving even higher average throughput based on currently implemented technologies," said the firm's report.



Hopefully this is something of a preview of what to expect from Sprint in the coming months.

Many of our S4GRU members would be more accurately represented by a clip of Homer bopping the bologna, varnishing the flag pole, choking the bishop over very high bit rates.  But we will spare the children that explicit image.





It's for the best, really. Oh wow, now I'm trying to imagine S4GRU members as Simpsons characters. This is going to require some time to mull over and make proper decisions.
