4 year old: When are we going to the yellow planet?
Father:
What do you mean by “the yellow planet”?
Page - 3
Do you want to see the Sun? (or in Wi-Fi terms “isotropic radiator”)
Do you want to go to
Legoland (Space)?
Or is there a real
yellow planet?

A few weeks later at Singapore Changi Airport…

On the ground: Airport – my definition
• An airport is the entry/exit port of a country and important for the economy (business, tourism, etc.)
• An airport either works or it does not work • Fast movement of crowd (e.g. straight walking paths and not zig-zag through small corridors
or via stairs/elevators, buses)
• Fast Baggage Handling Systems • Short Taxi queues • Easy access to information / directions • Easy access to wireless communications without going
through difficult sign-up procedures • Radar avoidance “Dynamic Frequency Selection – DFS” • Safety and Security

Airport Wi-Fi … installations http://www.globeron.com/freedownload/services/Globeron-Wi-Fly-or-We-Cry-7-Aug-2016.pdf HD-MCII – High Density Moving Clients Induced Interference
• Overlapping channels up to 80 MHz • High-Gain omni-directional
antennas at waiting areas • No coordination between
service providers • Cabling termination points
limiting position of APs • Too many APs in the same
areas • Lot of HD-MCII

In the Air: Airplanes – my definition
• An airplane brings you from airport A to B as fast as possible and safely.
• Airplanes • Easy to walk through corridors and store luggage • Good air-conditioning (not too hot/cold and clean-air) • In-flight entertainment systems • Free food vs paid food • Convenient seats in economy class with facilities like
electricity power for laptop and USB-power for smartphone
• Wi-Fi and Cellular (Roaming) coverage (for a reasonable cost)

Example of in-flight systems
Economy class
• 2x USB connectors • Power plug
• USB interface • Audio/Video interface • Sometimes ethernet
interface

What do you do if a screw is missing on an
airplane or hits the window?
What do you do when you see WEP and IBSS devices ?
Page - 16
Where are these devices in the airplane?
1st class, business, economy, the bar/lounge ?
Page - 17
Tablets use these ad-hoc WEP connections
to control the screen
Page - 18
RF communication equipment • Is it allowed to use communication equipment on an airplane?
• Some flights allow all your devices on all time during the flight, some do not allow it at all
• RF-scanners (any frequency), e.g. Software Defined Radios (SDR) • Spectrum Analysis • Protocol Analysis • But what about the devices we use everyday (laptops,
tablets, smartphones, Internet of Things)
• There is no classification of Wi-Fi tools
