AirO is intended for technical and not-too-technical owners of Wi-Fi capable Android devices. It displays the health of the Wi-Fi (“Local Area”) connection, and measures the characteristics of a “Wide Area” connection to a server deeper in the network. It can be used to answer questions like: • What’s wrong with my Wi-Fi today? • How strong is my Wi-Fi signal? • Is there evidence of wireless interference? • Is the problem in the Wi-Fi connection, or out on the Internet (or corporate network)? • Is the overall connection to the data center good enough to run my corporate apps? For an admin guide, including instructions on setting up your Aruba network so mDNS (AirGroup) automatically configures target addresses for AirWave and iPerf servers (allowing the app as downloaded to work on different networks without user interverntion) see the Air Observer Admin Guide hosted on the Aruba Airheads Community web page http://community.arubanetworks.com/t5/Aruba-Apps/New-Admin-Guide-for-the-AirO-Air-Observer-app/td-p/229749 (or go to community.arubanetworks.com and search for "AirO"). The top “Wi-Fi and Local Area Network” section of the screen displays three measurements that show the health of the Wi-Fi connection: • Signal Strength or RSSI in dBm We measure signal strength first because if it’s poor, there is no chance of getting a good connection. The remedy, in simple terms, is to get closer to the access point. • Link Speed. The usual cause of low link speeds is poor signal strength. But sometimes, even when signal strength is good, interference on the air from Wi-Fi and non-Wi-Fi sources reduces link speeds. • Ping. This is the familiar ICMP echo test to the network’s default gateway. A low link speed will often cause long ping times. If link speeds are good but pings slow, it may be a long way to the default gateway over a narrow broadband connection. The lower section of the screen displays results from tests between the device and a server computer, usually in the corporate data center or on the Internet. The address of this server is chosen from a number configured in ‘settings' – but once chosen, only one server address is used for these tests. • Ping. There is a ping measurement to this server. It is the same ping test as above, but because this one goes farther it will normally (but not always) take longer. Again, 20msec would be fast and 500 msec would be slow. Some networks may block ICMP (ping) traffic. In this case, the Wide Area Network ping test will always fail, but normal (e.g. Web) traffic may pass.
