186GB in an LTE Network - been there, done that (Stockholm - part I)
Signals Research Group, LLC, March 2010
Test results and analysis of an extensive LTE drive test conducted in Stockholm, Sweden
During the week of February 8th the publisher conducted what is arguably the most scientific and exhaustive independent performance analysis ever conducted of an LTE network(s). During the publisher's tests, which were almost entirely conducted in vehicular or pedestrian mode, they transferred nearly 186GB of data, or nearly twenty-five times more data usage than what a typical fixed broadband user consumes in an entire month.
As part of this research project the publisher had the opportunity to use XCAL LTE drive test tool and XCAP LTE post-processing tool from Accuver. To the best ofthe publisher's knowledge the XCAL/XCAP solution was the only solution available at the time which could interface with the Samsung and LG LTE solutions, not to mention other vendor's HSPA+ or Mobile WiMAX chipsets, and this capability proved invaluable during this entire effort. With the use of this tool and the publisher's methodical
approach to testing and analyzing the network, the publisher has arguably reached fairly conclusive and statistically valid opinions about how LTE performs today.
Given the breadth and depth of this analysis the publisher has divided the report into two separate issues.
Specific topics in this report include the following:
The KPIs. In addition to the typical downlink and uplink data rates, the publisher looked at a number of other KPIs, including CINR, RSSI, resource block allocation, modulation scheme (Antenna 1 and Antenna 2), MIMO type, and BLER. Further, during the post-processing phase they analyzed these KPIs by several different means, including, throughput versus CINR, CINR versus RSSI, handover success rate, throughput during a handover, and CINR versus modulation scheme, to name a few.
The Video. Check out the video that the publisher posted to the SRG website.
The Data. If your organization is interested in obtaining the complete set of raw data, please contact us for licensing
information.
Comparing the Incomparable. While comparing the two networks is somewhat an apples-to-oranges comparison, the publisher presents a wealth of information that makes such a comparison possible (with a few caveats), not to mention comparisons with HSPA/HSPA+ and Mobile WiMAX.
A Perspective. The publisher offer a perspective on what LTE means for the typical mobile data user and they include results from using LTE to do basic mobile data applications.
The Appendix. In total, the report contains 92 figures or tables. In order to not over burden the reader with a ton of
information, the publisher includes many of the figures in the appendix for future reference.
