WiFi communication system and method thereof

Abstract

The invention discloses a WiFi communication system and a method thereof. The WiFi communication system includes a WiFi signal transmitter and a WiFi signal receiver. The WiFi signal transmitter is connected with a WiFi chip on a transmitting end and is used for performing frequency-hopping and underlocking treatment of initial WiFi radio frequency signals output by the WiFi chip on the transmitting end. And the WiFi signal receiver is connected with a WiFi chip on a receiving end and is used for receiving the WiFi signals after the frequency-hopping and underlocking treatment and output by the transmitter, restoring the WiFi signals after the frequency-hopping and underlocking treatment to the initial WiFi radio frequency signals and sending the initial WiFi radio frequency signals to the WiFi chip on the receiving end for processing. According to the invention, through the frequency-hopping and underlocking treatment of the WiFi signals, WiFi signal transmitting frequency is reduced and WiFi signal transmission range can be enlarged.

Description

Technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a WiFi communication system and method. Background technique [0002] Wireless Fidelity (WiFi) is a technology that wirelessly connects personal computers, handheld devices (such as mobile phones, PDAs) and other terminals to each other. Currently, WiFi mainly uses two frequency bands, 2.4 GHz and 5 GHz in the ISM (Industrial, Scientific, Medical) frequency band. Because Wi-Fi frequency bands do not require any telecom operation license worldwide, WLAN wireless devices provide a wireless air interface that can be used worldwide, with extremely low cost and extremely high data bandwidth. Users can quickly browse web pages within the Wi-Fi coverage area and answer and make calls anytime, anywhere. With the Wi-Fi function, you can make long-distance calls (including international calls), browse the web, send and receive e-mails, download music, transfer digital photos, etc...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, due to the high frequency band used by the WiFi technology, the signal attenuates rapidly during the transmission process, resulting in a very short communication distance of the WiFi signal in the prior art

In the prior art, the communication distance of WiFi signals is very short, which further leads to the need to deploy a large number of base stations to achieve the coverage of WiFi signals in a certain area, wasting hardware resources

At the same time, due to the crowded signals in the ISM frequency band, there are many noises, and the WiFi signals in the prior art are also susceptible to interference.
