Recently, the need to build functional and secure local computing corporate networks has become increasingly acute. Examples of such networks are, for example, local-computer networks of operational headquarters for the liquidation of emergencies, as well as special operations. An important aspect of the organization of such networks is the speed of network deployment, the ability to establish communication with relatively remote sites and also with mobile network subscribers. For these purposes, it seems promising to use the capabilities of Wi-Fi and WiMAX technologies.
When designing such corporate networks, there is a need to minimize the leakage of information through various channels and detuning from interference. These measures ensure, respectively, the confidentiality of the messages exchanged.
An important task in the context of the design of wireless networks is also the task of maintaining mobile dedicated objects at a distance of 1−5 km, at which high-speed data must be transmitted in real time. To solve this problem, it is proposed to use a rapidly deployable antenna system consisting of elements (horn antennas) having narrow directional diagrams with a high gain. In this case, the antenna elements are located along the ring and in several tiers. Such an antenna system allows to establish an effective radio channel with a remote mobile network subscriber with the possibility of detuning from interference.
