Low-speed wireless relay communication system

Abstract

The invention provides a low-speed wireless relay communication system, which is characterized in that: it includes a source computer, a repeater, two 3G routers and a sink computer, the source computer is connected to a 3G router through a repeater, and another 3G router Connected to the sink computer, the two 3G routers are connected through a 3G wireless communication link; the present invention can effectively solve the problem of low-speed data wireless transmission in the wireless signal shaded area, and use the relay communication mode to pass the signal of the shaded area through the relay Transmitters are forwarded step by step to non-blocking areas; the invention can be applied to various wireless communication systems where the required rate is not high but there may be signal shadowing areas, and the performance is good.

Description

technical field [0001] The invention relates to a low-speed wireless relay communication system. Background technique [0002] In many wireless communication systems, due to the particularity of the application environment, the wireless signal is blocked, resulting in communication interruption, and most of the communication systems need to transmit a small amount of data, which belongs to the low-speed wireless communication system. [0003] For example, in the remote real-time tracking system of vehicle position, the communication equipment installed on the tracked vehicle needs to send the position of the vehicle to the monitoring center through the wireless communication link in real time, and when the vehicle runs into a long tunnel, the wireless signal is blocked. As a result, communication is interrupted. [0004] For another example, in the underground room temperature and humidity monitoring system, due to the shielding effect of the underground environment on elec...

Problems solved by technology

[0003] For example, in the remote real-time tracking system of vehicle position, the communication equipment installed on the tracked vehicle needs to send the position of the vehicle to the monitoring center through the wireless communication link in real time, and when the vehicle runs into a long tunnel, the wireless signal is blocked. resulting in a loss of communication

[0004] For another example, in the underground room temperature and humidity monitoring system, due to the shielding effect of the underground environment on electromagnetic waves, if a wireless method is used, it is difficult for the signal to be directly transmitted to the ground
