Embodiment
Below in conjunction with accompanying drawing, the system of the minimizing WiMAX module in the present invention and WiFi module mutual interference is described in further detail.
Please refer to Fig. 1 and Fig. 2, the system 100 of the minimizing WiMAX module in the present invention's one better embodiment and WiFi module mutual interference is applied in terminal equipment 200, wherein this terminal equipment 200 comprises WiMAX module 201 and WiFi module 202, and this system 100 is for reducing the mutual interference between these multimode terminal 200 WiMAX modules and WiFi module.In the present embodiment, this WiMAX module 201 and a communication base station 300 communicate, and according to these communication base station 300 assignment frequency work.This system 100 is selected the operating frequency of WiFi module 202 according to the operating frequency of this WiMAX module 201, to reduce the mutual interference between WiMAX and WiFi.General, the difference of the operating frequency of the operating frequency of WiMAX module 202 and WiFi module 201 is larger, and the interference between WiMAX and WiFi is fewer.Therefore, in the present embodiment, this system 100, when selecting the operating frequency of WiFi module 202 according to the operating frequency of this WiMAX module 201, is selected the operating frequency large with the operating frequency difference of WiMAX module 201 as far as possible.
In the present embodiment, the operating frequency range of this WiMAX module 201 can be first frequency scope 2.3GHz-2.4GHz, can be also second frequency scope 2.5GHz-2.7GHz.The operating frequency range of this WiFi module 202 is 2.412GHz-2.472GHz, between first frequency scope and second frequency scope in this WiMAX module 201.The operating frequency range 2.412GHz-2.472GHz of this WiFi module 202 is also divided into a plurality of working frequency range from low to high.In the present embodiment, the operating frequency range 2.412GHz-2.472GHz of this WiFi module 202 is divided into 13 working frequency range, the centre frequency of every two working frequency range differs 0.005GHz, the centre frequency of the first working frequency range that its medium frequency is minimum is 2.412GHz, the centre frequency of the second working frequency range is 2.417GHz, by that analogy, the centre frequency of the 13 working frequency range is 2.472GHz.In other embodiments, the operating frequency range 2.412GHz-2.472GHz of this WiFi module 202 is divided into the working frequency range of other quantity.
This system 100 comprises frequency acquisition unit 10, comparing unit 20 and frequency setting unit 30.
This frequency acquisition unit 10 is for obtaining the operating frequency of being distributed to this WiMAX module 201 by communication base station 300.
This comparing unit 20 compares for operating frequency and a default operating frequency of this WiMAX module 201 that this frequency acquisition unit 10 is got.In the present embodiment, within the scope of the second frequency of this default operating frequency in WiMAX module 201 operating frequency ranges, be 2.6GHz.In other embodiments, this default operating frequency can be also other values in the operating frequency range of this WiMAX module 201.
This frequency setting unit 30 is for obtaining the comparative result of this comparing unit 20, and according to this comparative result, sets the operating frequency of this WiFi module 202.
Particularly, when comparing unit 20 determines that the operating frequency of these WiMAX modules 201 is greater than this default operating frequency 2.6GHz, the operating frequency that this frequency setting unit 30 is this WiFi module 202 by the arbitrary frequency setting that is less than or equal to the centre frequency of the working frequency range in the middle of the operating frequency range that is arranged in this WiFi module 202.For example, when the operating frequency that gets this WiMAX module 201 when this frequency acquisition unit 10 is 2.69GHz, this comparing unit 20 determines that the frequency of this WiMAX module 201 is greater than this default operating frequency 2.6GHz, and this frequency setting unit 30 is set as the centre frequency 2.442GHz that is arranged in the 7th middle frequency range of WiFi operating frequency range the operating frequency of this WiFi module 202.Because when the operating frequency of this WiMAX module 201 is greater than this default operating frequency, the difference of the frequency of this WiMAX module 201 and WiFi module 202 operating frequency ranges is enough large, can be because of interference effect proper communication mutually between WiMAX module 201 and WiFi module 202.In other embodiments, the frequency values that this frequency setting unit 30 also can be less than frequency values other frequency ranges of the 7th frequency range is set as the frequency values of this WiFi module 202.
