The American company Motorola has just presented a telephony project. As so far telephone calls pass through different telephone stations, they are joined together by cables.

With the system proposed by Motorola, all the phones in the world would be wireless. The association would be satellite. It would take 67 satellites 700 km high. In this system, when a subscriber requests the line he will contact the nearest satellite. The phone will have an antenna for communication.

As for costs, the latest figures are not well known, but it can be advanced that the cost of each satellite is 187 billion dollars.
