Although inflight wee-fee service is really nothing new... (some airlines have had it for a while, some even already gave-up on the service), in the past year it's got some traction again with the release of the service by some airlines in the US and some other countries. The talk will cover things like wi-fi infrastructure, auth stuff, spectrum analysis, protection mechanisms (if any), general usage, user device types and uplink technology that actually makes the user hit the "tubes". Data collected a few years ago in flights using older technologies, as well as data collected in newer ones and the possible use of tools available will be discussed.
