Design of transmitters for computer communication using Public Alpine Wireless Network

The Public Alpine Wireless Network (PAWN) is a complete wireless microwave communication system. It has been designed to be implemented economically in isolated mountainous terrains where there are only about 100 subscriber units in approximately 5000 km/sup 2/, PAWN works in the microwave frequency range of 1-9 GHz. PAWN is a digital communication network, Since individual terminals are far apart, PAWN need not transmit all signals in all directions. Repeaters are used for selecting the range of frequencies in its region. A volatile stochastic code is introduced to avoid illegal tapping of information. The repeaters and the receiver are described.<
