Problem: Modern communication technology has brought us Internet connectivity just about anywhere on the planet. One very useful tool has been WiFi on airplanes. Communicating with a moving target is significantly more difficult than communicating with something that is stationary, especially an object that is traveling at 600+ mph.

1. Define and describe what technologies are currently in use for Wifi on airplanes. There are currently two methods in use. Describe how each accomplish the same task using different communication techniques.

2. Until recently, it has been very expensive to make phone calls while on an airplane. However, we've discussed that voice and data are really the same thing. Some airlines have started to allow VoIP conversations using airplane WiFi. One can quickly see that 200 people making phone calls can become a significant disturbance, especially when you are trapped in an aluminum can. Give your opinion on whether telephone conversations should be allowed on airplanes and suggest possible compromises.
