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.
The external environments of the aircraft include taxiing, takeoff, cruise, and descent; outside temperature from below â55Â°C (â65Â°F) to over 50Â°C (122Â°F); ambient pressure from about 10.1 kPa (1.5 psi) to 101 kPa (15 psi); and water content from virtually dry to greater than saturation.
