Device for enhancing signal-to-noise ratio when WiFi, 4G and WiMAX coexist

Abstract

The invention relates to a device for enhancing a signal-to-noise ratio when WiFi, 4G and WiMAX coexist. The device comprises a wireless processing module and an antenna, wherein a filter is connectedbetween the wireless processing module and the antenna; the filter is formed by connecting an LC series circuit and an LC parallel circuit in series; the LC series circuit is used for filtering signals with lower frequency received by the antenna; and the LC parallel circuit is used for filtering signals with higher frequency received by the antenna. According to the device, the production cost of the product can be effectively reduced, and the transceiving frequency is adjustable.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a device for enhancing the signal-to-noise ratio when WiFi, 4G and WiMAX coexist. Background technique [0002] The transmission of wireless signals such as 4G, WIFI, and WIMAX in the same air medium will increase the noise of other wireless signals and reduce the signal-to-noise ratio of its own signal. The final phenomenon is that the wireless transceiver rate decreases. [0003] One of the current common practices is to use a shielding cover in the device to shield the transceiver circuit, or use a modular band-pass filter or low-pass filter in the transceiver circuit for filtering. [0004] In the above method, the use of the shield will significantly increase the processing steps and difficulty of the equipment, resulting in a sharp increase in the production cost of the product, and it is also not conducive to the heat dissipation of the transceiver circuit. ...

[0002] The transmission of wireless signals such as 4G, WIFI, and WIMAX in the same air medium will increase the noise of other wireless signals and reduce the signal-to-noise ratio of its own signal. The final phenomenon is that the wireless transceiver rate decreases

[0004] In the above method, the use of a shield will significantly increase the processing steps and difficulty of the equipment, resulting in a sharp increase in the production cost of the product, and it is also not conducive to the heat dissipation of the transceiver circuit

The use of a band-pass filter or a low-pass filter will increase hardware costs. On the other hand, since the parameters of the band-pass filter or low-pass filter are fixed, the transceiver frequency of the transceiver circuit cannot be adjusted, resulting in product maintenance. It is very inconvenient when debugging and debugging, which directly increases the production and maintenance costs of the product
