Problems solved by technology

In the prior art, due to the high frequency of the frequency band used by the WIFI technology, the wavelength of the signal is relatively short, and the signal attenuates quickly during the transmission process, so the communication distance of the WIFI signal in the prior art is very short

Abstract

The invention discloses a WIFI long-distance transmission module with a double-direction frequency conversion technology. The WIFI long-distance transmission module comprises a transmit-receive antenna, a frequency conversion module, a control module, a local oscillator module and a power supply module. The frequency conversion module is connected with the local oscillator module which provides local oscillator signals. The frequency conversion module receives or transmits WIFI signals through the transmit-receive antenna. According to the WIFI long-distance transmission module with the double-direction frequency conversion technology, when signals are sent, the signals are subjected to down-conversion to 0.4GHz-0.485 GHz, then transmission is carried out, the wave length of signals is increased, long-wave signals are more stable than short-wave signal, a transmission process cannot be interfered by outside easily, damping is low, diffraction capacity is strong, and transmission distance is long. The module has the advantages of being large in sending power, high in receive sensitivity and low in transmission loss, and accordingly signal transmission distance is greatly increased, the transmitter covering range is increased, the deploy amount of a base station can be lowered, and the cost is the whole project is lowered.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a long-distance transmission module for WIFI communication using bidirectional frequency conversion technology. Background technique [0002] WIFI (Wireless Fidelity), short for wireless fidelity technology, is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as PDAs and mobile phones) to each other. Since the frequency band of Wi-Fi does not require any telecommunication operating license in the world, it provides a wireless air interface with extremely low cost and high data bandwidth that can be used worldwide. Users can quickly browse the web within the Wi-Fi coverage area, and answer and make calls anytime, anywhere. With the Wi-Fi function, we can make long-distance calls (including international calls), browse the web, send and receive emails, download music, transfer digital photos, etc., without worr...
