Description

The technical solution relates to the field of organizing wireless local area networks for data transmission controlled by a router between many users in the field of network deployment.

Currently, wireless LANs are becoming more widespread in cases:

- when it is necessary to deploy a local network as soon as possible, since there is no need to lay a connecting cable;

- when it is difficult or impossible to install the patch cable due to architectural restrictions or other features of the local area network deployment area.

The closest set of essential features to the claimed technical solution is a method of radio communication in a wireless local area network (RU, 2207724, Н04В 7/00), including many transceiver devices capable of communicating with each other, which consists in choosing a temporary network coordinator from a variety of transceiver devices , orientation of the antenna beam with a controlled radiation pattern of client devices in the direction of the temporary network coordinator, which gives permission to transmit information to one of transceiver devices switched to client mode.

This method of radio communication is implemented in a wireless local area network, including many transceiver devices, one of which is the temporary coordinator of the network. This network has transceivers that are equipped with an antenna with a controlled radiation pattern and means for operating the antenna in an omnidirectional mode, in a directional scanning mode or in a stationary directional mode, as well as means for identification that is responsive to signal transmission, including a clock signal,

an identification signal designed to direct the antenna in the direction of the transmitted signal.

The disadvantage of this technical solution is that it is ineffective in mobile communication systems, that is, where network elements are constantly moving in unforeseen directions. In this case, the transmission speed drops significantly, since a constant restructuring of the radiation pattern is required.

In addition, any interference arising in the data transfer zone causes a network rebuild, which also leads to a decrease in the data transfer rate

The objective of the proposed technical solution is to increase the reach or range of users, as well as increasing the speed of data transfer, improving the quality and reliability of communication.

The problem is solved in that a wireless coordinator (router) is introduced into a wireless local area network, which includes many transceiver devices capable of communicating with each other, located at a distance from the deployment area of the local network, and a navigation unit is included in each transceiver device.

Transceiver devices communicate with each other along a broadband path located in the microwave range. Each transceiver can operate in repeater mode if two or more users are outside the communication zone.

Each transceiver device consists of: an microwave array antenna unit; RF antennas; microwave transceiver; RF transceiver; control controller; navigation block. The control controller transmits / receives data via microwave, RF transceivers; controls the radiation pattern of the microwave unit antenna unit; and also reads data from the navigation unit.

The router manages the transceiver connections. The device determines the most optimal data transmission paths based on

congestion of various network sections, and also redirects data in case of failure of one of the transceiver devices. Communication with the router is via a narrowband path located in the high frequency range. Communication with the router via a separate radio channel can significantly increase the bandwidth of the communication channel between users of the local network. Given that the optimal data path is computed by the router, the computational load from local transceivers is also reduced.

The introduction of a permanent coordinator (router), eliminates the time spent on determining the temporary coordinator, since each transceiver is directly connected by the router.

The navigation unit included in the transceiver allows you to clearly determine the location of subscribers, due to this, you can immediately accurately direct the antenna, adjust the radiation pattern, excluding the scanning mode. In this case, the router can more accurately determine more reliable data transmission paths.

This solution allows more efficient use of the radio frequency path, and, therefore, significantly increases the transmission speed of transceiver devices located in the local area.

Communication with the router via the RF path allows you to place the router at a considerable distance from the area of the location of the transceiver devices, which makes it possible to remotely monitor and control the network status.

The utility model is illustrated by the following drawings:

Each transceiver device consists of: a microwave array antenna unit (6); RF antennas (7); microwave transceiver (8); RF transceiver (9); control controller (10); navigation block (11). The control controller transmits / receives data via microwave, RF transceivers ((8) and (9)); controls the radiation pattern of the microwave unit antenna unit (6); and also reads data from the navigation unit (11). An output (12) to an external device from the control controller (10) is also provided.

Thus, the implementation of the utility model allows us to solve all the tasks.
