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!
