A wireless access point is required for connecting wireless devices to a network. Most home networks rely on one wireless router combination device to fill this role. A home automation controller enables low-power wireless communications with simple, non-data-intensive devices such as light bulbs and locks.
I fly passenger Airbus A330s and A340s. I've never flown a cargo only aircraft so I can only answer about the passenger Airbus. We can set the temperature in the back cargo compartment (the hold or the bulk we call it) between 5 degrees Celsius and 25 degrees Celsius. The normal position for the selector is around 15 degrees Celsius.
Airplanes are pressurized because the air is very thin at the altitude they fly. The average passenger jet has a cruising altitude of about 30,000 to 40,000 feet. At this altitude humans canât breathe very well and our body gets less oxygen. This is called hypoxia and can cause slower thinking, dimmed vision, and death.
