Built In EV-DO Comparison for Dell,
Lenovo and HP
Test report prepared under contract from Dell Inc.
Executive Summary
Dell Inc. commissioned VeriTest, the
testing
service
of
Lionbridge
Technologies Inc., to conduct a
competitive analysis comparing the
performance of built-in EV-DO (Rev-A)
mobile broadband modules using
Verizon Wireless BroadbandAccess.
VeriTest conducted a series of tests to
find which notebook had the best
performance in terms of overall data
throughput speed and performance. The
notebooks tested in this study include
the following Business Class models.

included Intel Core 2 Duo processors as
well as 2 GB (2 x 1GB) of random
access memory (RAM). For a list of complete specifications for each notebook, please refer to
Appendix A.
In order to best replicate the end user experience, each notebook’s operating system type was
installed according to what is used the most from a business perspective. Business class models
included Microsoft Windows XP Professional with Service Pack 2.

Tests were conducted in the following US cities over a 29 day period using Verizon Wireless
BroadbandAccess.
•
•
•
San Diego, California
New York, New York
Chicago, Illinois
Three test locations were used in each city. All notebooks were tested on the same day for each
location. Each location was tested on separate days to account for network variability. The final
result for each test was calculated by averaging the encountered results from multiple test
iterations for each location. Six (6) to ten (10) iterations were conducted for each test.
The following tests were conducted:
A. Web Downloading Test - to measure throughput when downloading 1MB and 2MB
web files via HTTP protocol.
B. FTP Send and Receive Test - to measure throughput when transferring 1MB and
2MB files to and from web servers via FTP protocol
Upon completion, the study findings show that on average, the Dell Latitude D630 provided 36%
more throughput than the HP 6910p and 88% more throughput than the Lenovo ThinkPad T61 for
download speed.
The Dell Latitude D630 had an average throughput speed averaged across the FTP and Web
Downloading tests of 1023 Kbps. The HP 6910p had an average throughput of 753 Kbps and the
Lenovo T61 had an average throughput of 545 Kbps.
Please refer to the Test Methodology section of this report for complete details of how testing was
conducted. All units were tested using default factory settings. Lionbridge confirmed that all
notebook computers were new and unopened prior to testing and ensured all tests were
completed with impartiality.
Test Results
The following section details the results from testing.
Web Download Throughput
Goal: Benchmark throughput when performing web downloads via HTTP using a low traffic server
hosted by a local internet service provider.
Summary of Results: The Dell Latitude D630 was on average 43% faster than the HP 6910p and
74% faster than the Lenovo T61 when downloading a 1MB zip file from the web. The Dell D630
was on average 27% faster than the HP 6910p and 80% faster than the Lenovo T61 when
downloading a 2MB zip file from the web.

Test Methodology
Dell Inc. commissioned VeriTest to conduct a competitive analysis comparing performance of
built-in EV-DO (Rev A) mobile broadband modules. VeriTest conducted a series of throughput
tests to measure which notebook had the highest performance.
Notebook Configurations
Test conditions were designed for the notebooks to be as close to an out-of-the-box configuration
as possible, but some third party software, such as firewalls and virus protection, had to be
disabled. This ensured that some of this software did not affect download speed.
Integrated EV-DO Comparison for Dell, Lenovo and HP

The following software was required for testing which needed to be installed:
o
Wget for DOS (an application distributed under the GNU license) for the non-interactive
Web Downloading Test.
Test Locations
The test locations included areas with low, marginal, and strong coverage. Locations used were
deemed typical for users of built-in mobile broadband and included hotels and coffee shops.
Some locations provided unreliable connections resulting in data with such large standard
deviations as to be statistically useless. Data from these locations was not used in this report.
Several test runs would take 8 hours or more requiring the availability of AC power to keep the
notebooks charged, however, notebooks tested were not connected to AC power during testing.
Test Run Conditions
To keep the testing notebooks from possessing any advantages over each other based on
location, orientation or configuration, the test design called for the following conditions to be met
before testing could begin:
o
o
o
o
o
o
Each computer must be placed in the same point of origin and facing the same direction
Each LCD monitor must be tilted back at approximately 110 degrees
Each computer must be running on battery only, to simulate a typical user experience
Power settings must be set to Always On
All brightness settings must be maximized
Device radios are to be powered off unless when under test
There are many factors affecting actual throughput analysis (e.g. structures, latency, and network
traffic). Because these factors were out of our control and testing was not done in a controlled
lab the results may not be reproducible. The tests were designed to be objective by ensuring that
each notebook was affected by the same or similar environmental factors.
Test Run Details
After test setup was complete and all test run conditions were met, all notebook tests were
repeated from six (6) to ten (10) iterations. A completed iteration is defined as a single test
executed once on all three notebooks. Interleaving the tests from notebook to notebook helped
ensure that any network traffic or signal fluctuations would affect all notebooks equally minimizing
factors that can cause network variance such as network traffic. Only one computer was
connected to the Verizon Wireless BroadbandAccess service at a time. Only one notebook
module was powered on at a time. The test run was complete when all iterations were complete
for all tests.
Calculating Average
Once a test run was complete, the recorded data points for each test location were averaged.
These results can be found in Appendix C: Detailed Results.
Test Details
The following describes each test in detail and includes information on test development,
description of execution and data gathering.
Integrated EV-DO Comparison for Dell, Lenovo and HP

A. Web Downloading Test
Test Description
Wget for DOS was used to download a 1 megabyte and 2 megabyte zip file from a web
site. Zip files were used to eliminate the possibility of file transfer compression affecting
test results.
Test Development
The Wget application was installed on each notebook. A batch file executed the Wget
command with the logging option to download the two zip files and log the results. The
zip files were located on a low traffic web server from a local ISP.
Test Execution and Data Gathering
Double clicking the batch file would run the test. A log file was created on the desktop
upon completion. The start and stop time data as well as the Kb/s from each download
were recorded into an Excel spreadsheet to be averaged.
B. FTP Test
Test Description
FTP is one of the most common methods for transferring large files over the internet. To
test throughput speeds via FTP, Microsoft XP’s integrated FTP client was used to
download and upload a 1 megabyte zip file and a 2 megabyte zip file. Zip files were used
to eliminate the possibility of file transfer compression affecting test results.
Test Development
A batch file was written to log onto an FTP server and run put/get commands which
would send and receive the files via FTP then log the results to a log file on the Desktop.
The FTP server used for this test was provided by a low traffic local ISP.
Test Execution and Data Gathering
Double clicking the batch file would run the test. Upon completion a log file was created
on the desktop. The time in seconds it took for each download and upload to complete as
well as the Kb/s were copied into an Excel document in order to be averaged.
