DUBLIN--(BUSINESS WIRE)--Research and Markets (http://www.researchandmarkets.com/research/6mc7g7/signals_ahead) has announced the addition of the "Signals Ahead: 124.2 GB in a LTE TDD Network" report to their offering.
Signals Research Group (SRG) conducted what we believe is the first exhaustive [and exhausting] independent analysis of LTE TDD forpublic consumption. Over a four day period in late August, we conducteda drive test of Softbank's LTE TDD and LTE FDD networks in thegreater Tokyo region. In addition to comparing the two LTE duplexschemes while doing lengthy downlink and uplink throughput tests ina mobile environment - we transferred 124.2 GB just on the LTE TDDnetwork during these tests - we also looked at the performance of the twoduplex schemes with more typical applications.
This effort would not have been possible without the support of Accuver, who provided us withaccess to its XCAL data collection tool and its XCAP post-processing software. We have used thesolution numerous times over the last several years so we are very accustomed to using it, althoughwe do stumble upon new capabilities and features each time we use it. In our most recent benchmarkstudies, specifically LTE TDD in Tokyo and LTE Advanced Carrier Aggregation in Seoul, thesolution's ability to support recently introduced technology features, including Category 4 chipsetsand Carrier Aggregation, proved to be invaluable.
This drive test campaign was entirely self-sponsored although we did receive logistical support inthe form of test SIMs, a high bandwidth server, and mobile devices. SRG assumes full responsibilityfor the analysis and commentary included in this report.
Although LTE TDD and LTE FDD are merely different duplex options from the same standard,there is still a very robust interest in how LTE TDD performs. In theory, the performance of LTETDD should be largely comparable to the performance of LTE FDD, and Signals Ahead readers arewell-versed in that regard. However, there are practical matters, such as the frequency band whereLTE TDD is deployed and the downlink/uplink configuration of the available resources, whichmust be considered. For this reason, we focused our drive testing and analysis on specific areas thatwould allow us to quantify these differences in a real world network.
