WifiCopper running on the first machine where we've set transmission on channel 13, injection rate to 80 packets / sec, and packet size to approximately 1500 bytes / packet. In the example below we'll be using AirPcap/Wireshark вЂ“ that is, on one machine we'll run WifiCopper (to inject 802.11 packets) and on a second machine we'll run AirPcap/Wireshark (to capture packets).

CommView for WiFi, and OptiViewВ® Network Analyzer. We've had success using AirPcap/Wireshark, though other packet capture solutions are available - e.g. Whereas WifiCopper is used to inject wireless traffic, to complete this type of measurement it is also necessary to employ packet capture software. This is very useful вЂ“ network discovery tools and spectrum analysis can not make the same claim. Though this metric can not distinguish between interference versus obstacles or 'dead spots' being the cause of poor performance, since packet rates are measured then whatever improvements you make to the system should directly translate to better performance. When it comes to troubleshooting an 802.11 wireless network measuring the rate of packet capture may be a more valuable metric of the quality of 802.11 transmission / reception than RF spectrum analysis because you are measuring the real thing вЂ“ i.e.

Optimally configuring wireless networks based on packet capture rates.

You can't make these sorts of measurements using an RF spectrum analyzer, since it doesn't measure performance. channel selection, antenna location and position) such that packet rate is doubled, then you should see a similar improvement in the overall performance of the wireless network. That is, if you reconfigure a wireless system (i.e. Though poor packet capture rates can't distinguish between interference or obstacles that create 'dead spots' or poor antenna location or positioning, because you are measuring packet rates then whatever changes you make to the system to improve packet rates should directly be reflected in improved performance. When troubleshooting a wireless network, being able to measure packet capture rates may be more informative than RF spectrum analysis - because now you are measuring the real thing. Whereas WifiCopper is used to inject wireless traffic, to complete the measurements it is also necessary to use packet capture software. This makes it much easier to measure the quality of the transmission and reception performance on a particular 802.11 channel. bytes / packet) without the need of the client adapter associating with an access point. It is used to create wireless traffic on a particular channel and at a known level (i.e. WifiCopper is a unique, PC-based product that aids in testing WiFi wireless networks.
