Some airlines (Emirates, AirFrance, Aeroflot, and others) are doing a trick with communication in flight: GSM equipment works on board the aircraft (a box weighing only about a kilogram - a femtocell), which grounds all traffic via satellite. Those. in transit through a satellite, it transmits everything to the switch located on the surface of the Earth. And then you can fly over Africa, but at the same time, from the point of view of the network, be roaming in America.
It may seem that the lunar lander can also be equipped with such equipment, and communicate via satellite using more powerful transmitters. But no. The operation of a public land mobile network (that is how it is called: PLMN - Public Land Mobile Network) of the GSM or CDMA standard, etc. is based on signaling procedures and protocols, where the timing of receiving certain responses is also important. Even an ordinary registration of a telephone in the network is the work of an ensemble of all transit switches, a radio subsystem and several nodes of a home switch. When registering a phone, dozens of messages will pass between network elements. If at least one does not give an answer in time (within the allowed timing), nothing will work. The distance to the Moon will not allow observing these timings - the delay of the control service messages required for the equipment operation will be too long.
Of course not. Where are cell towers on the moon from GSM?
A macro cell is a standard base station on the basis of which mobile networks are built. It is characterized by a power of about 50 W and a coverage radius of up to 100 km (in the limit). The weight of the rack can reach 300 kg.
How many kilometers are there to the moon? (384 400 km)
