Digital Microwave Radio in the Frequency Band 4-4 to 26 GHz
Application:
Communicating between centers in Telecommunications and military centers
Product Introduction:
Point-to-point digital radios are designed and manufactured in 4.5, 15, 18, 23 GHz frequency bands. These radios are suitable for communicating between centers and other things such as rural and urban telephone communication.
The functional goal of the system is to transfer information in E1 and Ethernet protocols between two points with a fixed distance. These inputs are delivered to the internal unit and after performing the necessary processing and allocating space according to the bandwidth assigned to each of the inputs by the user, it multiplexes them and puts the result in the frame sent to the external unit. In fact, multiplexing and demultiplexing the input information with a specific protocol based on the bandwidth assigned to that type of information is the most important task of the internal unit and the work of modulation of the transmitted signal and demodulation and preparation of the received signal is performed in the external unit. Microwave sections and modulator/demodulator units are located in the outer unit area, and other components such as multiplexer and user interface ports are embedded in the inner unit. In radio transmission systems, the correct operation of the system is usually dependent on the correct operation of all its main components at the same time; Therefore, from the point of view of failure rate calculations, it is considered a serial system. Now, if some units that have a high probability of failure are paralleled with another unit, a new combination is created which is a series and parallel system, so the probability of failure is reduced. During the switch, it is very important to determine the damaged and healthy unit as well as the switch time. The main modules of this product are:
