What this is.
• Stats for wireless throughput• Methods• What we did• What you shouldn’t do• If time, what to look for in wireless
Evaluating Wireless
• Bodies method (Bakeoff)• Heat Map Method (Way Cool)• Fancy Spectrum (Software Radios)• Client/Server Method
Client/Server
• Server collects the data• Client sends the data• Test in a variety of ways
Iperf
• Free!• Iperf.sourceforge.net• Cross-platform
Including iOS- pay? Android?
• Hasn’t been updated since 2008 (?) (!)• en.wikipedia.org/wiki/Iperf• Can test ANY network
Iperf Usage• Gotta get it.
Source (Main) Pre-compiled (http://www.iperfwindows.com/
)(!)or… http://sourceforge.net/tracker/?func=detail&aid=3470334&group_id=128336&atid=711373
• Gotta build the command line Jperf Man Page/ Help Text
• Gotta start the server• Gotta kill firewalls
Values for Client
• Size of data packets• Type of data- TCP/UDP• Restrict bandwidth• Number of clients• Bytes vs. Time
Values for Server
• Service (dæmon) vs Command Line• Logging (or cut’n’paste)• Bytes- Digital vs Decimal• Interval
• Interval
• Interval!
