Functional capabilities of modern equipment for packet millimeter-wave radio communications

The article gives an overview of the functional capabilities of modern equipment for packet radio communications of the millimeter band. Practical usage examples of the equipment in the conditions of urban environment are presented. Advantages of using this equipment for telecom operators are given. Specific features of millimeter radio waves propagation in the atmosphere and the influence of precipitation, such as rain and snow, on the signal propagation range are indicated. The specifics of the radio channel capacity dependence on the signal bandwidth are indicated. The role of modulation type and gain factor in successful use of XPIC technology with the equipment studied is described. A multifactor analysis of the world and Russian manufacturers of packet radio communications equipment of the millimeter band was carried out. As a result of the analysis, the following characteristics were compared: maximum channel width, maximum signal propagation delay, modulation types used, equipment throughput, range and overall dimensions of the antennas. The main advantages and disadvantages are noted. The article makes some recommendations on the use of equipment models presented in the analysis. In this paper, we have analyzed a number of sources over the past five years. The legislative basis for the use of this equipment on the territory of the Russian Federation is indicated. The prospects of development of packet radio communication systems of millimeter band are described.
