Description

{System for managing customized IoT disaster safety in communication shadow areas and method thereof}

The present invention relates to a customized IoT disaster safety management system and method in a communication shadow area, particularly when a worker carrying a customized IoT disaster safety device detects a risk related to the worker while working in a communication shadow area. Alternatively, it relates to a customized IoT disaster safety management system and method in a communication shadow area that performs accident prevention and accident response functions to prevent major disasters when detecting danger around the worker.

Wireless communication is a communication method that uses radio waves to send and receive telegraphs without using wires.

Due to limitations in radio wave penetration, such wireless communication must rely on signals transmitted by reflection from surrounding terrain when there are large obstacles such as buses and trucks. Accordingly, there may be a problem in which the communication success rate and transmission distance are seriously reduced.

In addition, in a mobile communication system to which such wireless communication is applied, when connecting communication between a terminal, a base station, and a server, in cases where the terminal leaves the service area (Cell Boundary) of the base station or the quality of the wireless section deteriorates, the transmission and reception service environment There are cases where this gets worse.

In other words, in a mobile communication system environment, a shadow area may occur, which is an area where reception sensitivity at a base station or terminal is low due to a poor radio wave environment. In this shadow area, the BER (Bit Error Rate) or BLER of received data may occur. (Block error rate) increases, and SNR (Signal to Noise Ratio), which indicates the quality of the actually received signal, deteriorates.
