Signals and SBR cooperated to expand the throughput performance limit of LTE chipsets

ctiforum on May 27 (Yu Xin): Recently, SBR communications, the global leader in the field of network, service and device testing, announced that the company has cooperated with signals research group (SRG) to support Ericsson, Hisilicon, Intel, MediaTek Six LTE chipsets with cat 4 capabilities produced by Qualcomm and Samsung were tested in terms of data throughput performance. This research includes not only commercial chipsets, but also products that have not yet been put into commercial use. It is part of a series of overall LTE chipset performance analysis activities. One invention patent certificate is dazzling, and this series will also include LTE TDD and carrier wave polymerization in future reports

the key conclusions of this test include:

from the average throughput shown in each test, Samsung's pre commercial chipset has the strongest performance

the results show that under more challenging conditions, the performance difference will expand (low signal strength and high interference)

srg president Michael Thelander pointed out that when the overall performance of pre commercial chipsets is the best, we should also consider other factors, such as strict operator acceptance tests, and such tests are likely to find other problems that are not included in our research scope. For Samsung, this problem is not serious, because the company has put other LTE chipsets into commercial use. In addition, it is worth noting that the chipset with the best performance does not necessarily create the mobile device with the best performance, because poor antenna design or non optimized RF front-end may lead to serious deterioration of RF performance, which has been verified in the last study jointly organized by us and sboren

SBR CS8 mobile device testing system enables SRG to measure various chipsets under the same conditions and capture key performance indicators (KPIs), so that people can deeply understand why some devices/chipsets have different performance. Cybertron CS8 provides more value for research, because many mobile operators who recently released the system to optimize the commercial LTE network for the continuation of product structure have adopted the system

Nigel Wright, vice president of Cybertron communications, said: since the initial chipset benchmark research of signals research group in 2007, Cybertron has been able to cooperate with SRG again and demonstrate the continuous evolution of data throughput performance, which makes us very excited. Compared with the earliest research, the peak data rate observed today has increased by about 30 times. These results once again prove the great potential of LTE with the continuous development of the aerogel gel industry, and show the performance range of LTE in the complex environment of the next generation chipsets and devices

this study includes testing the LTE FDD data throughput performance of some of the most commonly used mobile chipsets in the industry. With the help of "peacock project", SRG started to test all chipsets in four modes. Category 4 devices can support up to 150 Mbps in a 20 MHz FDD channel, while Category 3 devices can only support 100 Mbps. In this study, these chipsets were placed under 29 different scenarios mixed with attenuation profiles, transmission modes and different MIMO correlation factors, and all tests were performed using the CS8 test platform of Cybertron
