[0002] With the advancement of wireless local area network (WLAN) technology, homes and businesses are increasingly relying on Wi-Fi as their primary means of network access. In recent years, new applications have emerged with higher throughput and latency requirements, such as 4K and 8K video (transmission rates can reach 20 Gbps), VR / AR, gaming (latency requirements below 5ms), remote work, online video conferencing, and cloud computing. Wi-Fi coverage is often determined by the output power of the radio frequency unit (RFU). Because each country has specific regulations on Wi-Fi's equivalent isotropically radiated power (EIRP), and Europe also has energy-saving requirements for enterprise resource planning (ERP), RFU output power cannot be increased indefinitely. Therefore, designing a system that intelligently adjusts RFU performance has become an urgent task. Summary of the Invention

[0019] The following describes various embodiments of the present invention in detail, with accompanying drawings as examples. In addition to these detailed descriptions, the present invention can also be widely implemented in other embodiments. Any easy substitution, modification, and equivalent variation of any of the embodiments described are included within the scope of the present invention and are subject to the claims of the present invention. In the description of the specification, many specific details and implementation examples are provided to enable the reader to have a more complete understanding of the present invention; however, these specific details and implementation examples should not be construed as limitations of the present invention. In addition, well-known steps or components are not described in detail to avoid unnecessary limitations of the present invention.

[0020] Please refer to Figure 1 , which is a functional block diagram of a wireless communication electronic device 100 according to an embodiment of the present invention. The wireless communication electronic device 100 is, for example, a router or an electronic device capable of providing radio frequency.

[0021] like Figure 1 As shown, the wireless communication electronic device 100 includes an antenna 110, a radio frequency unit 120, a power supply unit 130, and a processor 140. The radio frequency unit 120, the power supply unit 130, and / or the processor 140 may be physical circuits formed using at least one semiconductor process, such as a semiconductor chip or a semiconductor package. Specifically, the power supply unit 130 may be, for example, a high-efficiency voltage regulation module. The processor 140 may be, for example, a system on a chip (SoC). The radio frequency unit 120 may be, for example, a front-end module (FEM).

[0022] like Figure 1As shown, the RF unit 120 is electrically connected to the antenna 110. The power supply unit 130 is electrically connected to the RF unit 120. The processor 130 is electrically connected to the RF unit 120 and the power supply unit 130. The processor 130 is used to: when the wireless communication electronic device 100 operates in the first operating frequency band, control the power supply unit 130 to drive the RF unit 120 with a first driving voltage Vd1; and when the wireless communication electronic device 100 operates in the second operating frequency band, control the power supply unit 130 to drive the RF unit 120 with a second driving voltage Vd2, wherein the second driving voltage Vd2 is different from the first driving voltage Vd1. The wireless communication electronic device 100 of the embodiment of the present invention can control the power supply unit 130 to drive the RF unit 120 with different driving voltages according to different operating frequency bands. In this way, the RF unit 120 can be driven with appropriate driving voltages in different operating frequency bands, thereby increasing wireless communication efficiency and reducing unnecessary power consumption (producing the technical effects of energy saving and low radiation).

[0023] The driving voltage output to the RF unit 120 affects the output power of the RF unit 120. For example, the driving voltage is proportional to the output power. Different operating frequency bands have different allowed RF output powers. As shown in Table 1 below, it lists the maximum output power (for example, equivalent isotropically radiated power) limits corresponding to different operating frequency bands of the Canadian specification. For the operating frequency band of 5.15GHz to 5.25GHz, the maximum output power limit is 200 milliwatts (mW), while for higher frequency operating frequency bands, such as the operating frequency band of 5.725GHz to 5.825GHz, the maximum output power limit is allowed to be higher, for example, 1000mW. Table 1 takes six groups of operating frequency bands and maximum output powers as an example, but this is not used to limit the embodiments of the present invention. In another embodiment, there may be less than or more than six groups. Correspondingly, the number of driving voltage groups is not limited to two groups (the first driving voltage Vd1 and the second driving voltage Vd2), but can also be multiple groups.

[0025]

[0026] In one case, when the wireless communication electronic device 100 operates in an operating frequency band requiring low RF power, a low driving voltage is sufficient to drive the RF unit 120 to obtain communication quality that meets the expectations. In the same operating frequency band requiring low RF power, driving the RF unit 120 with a high driving voltage will result in unnecessary power consumption. In another case, when the wireless communication electronic device 100 operates in an operating frequency band requiring high RF power, a high driving voltage is required to drive the RF unit 120 to obtain communication quality that meets the expectations. In the same operating frequency band requiring high RF power, a low driving voltage is insufficient to drive the RF unit 120 (performance is not achieved).

[0027] Since the wireless communication electronic device 100 of the disclosed embodiment can drive the RF unit 120 with appropriate driving voltages in different operating frequency bands, the expected communication quality can be obtained in each operating frequency band while avoiding unnecessary power consumption (producing a technical effect of energy saving).

[0028] In addition, the processor 140 stores a correspondence R1. In this embodiment, the correspondence R1 is, for example, a correspondence between an operating frequency band and a driving voltage. The processor 140 is used to: when the wireless communication electronic device 100 operates in a first operating frequency band, query the first driving voltage Vd1 corresponding to the first operating frequency band according to the correspondence R1; and when the wireless communication electronic device 100 operates in a second operating frequency band, query the second driving voltage Vd2 corresponding to the second operating frequency band according to the correspondence R1. The first operating frequency band can be one of the multiple operating frequency bands listed in Table 1, and the second operating frequency band can be another of the multiple operating frequency bands listed in Table 1. In addition, the processor 140 can automatically detect a suitable operating frequency band in the area in which it is located. For example, the processor 140 can select the one with the least noise from the multiple operating frequency bands in the correspondence R1 based on the signal of the antenna 110.

[0029] In addition, the aforementioned correspondence R1 can be stored in the processor 140. The processor 140 further stores the country code CD and multiple sets of correspondences, one of the multiple sets of correspondences (i.e., the correspondence R1) corresponds to the country code CD. The multiple sets of correspondences R1 correspond to the communication standards of multiple different countries. The processor 140 is further used to: obtain the country code CD; and obtain the correspondence R1 corresponding to the country code CD among these correspondences. For example, if the country code CD represents Canada, the processor 140 obtains the correspondence corresponding to Canada (e.g., Table 1), and determines the driving voltage corresponding to the working frequency band based on the selected correspondence. In another embodiment, the processor 140 can store only one set of correspondences R1 corresponding to the country code CD, so that the correspondence R1 can be directly used without obtaining the country code CD separately. In another embodiment, the processor 140 can negotiate the transmission power with the interconnected device and select the corresponding driving voltage based on the negotiated power. For example, as a slave device, when it detects that the received signal power is too high (the distance is too close), it can reduce the transmission power and the radiation range, and select the driving voltage according to the transmission power.

[0030] Please refer to Figure 2 , which is Figure 1 Flowchart of a driving method of the wireless communication electronic device 100.

[0031] In step S110 , when the wireless communication electronic device 100 operates in the first operating frequency band, the processor 140 controls the power supply unit 130 to drive the RF unit 120 with the first driving voltage Vd1 .

[0032] In step S120 , when the wireless communication electronic device 100 operates in the second operating frequency band, the processor 140 controls the power supply unit 130 to drive the RF unit 120 with a second driving voltage Vd2 , where the second driving voltage Vd2 is different from the first driving voltage Vd1 .

[0033] The other steps of the driving method according to the embodiment of the present invention have been described above and will not be repeated here.

[0034] In another embodiment, Figure 1 The wireless communication electronic device 100 may also determine a driving voltage based on wireless signal power. For example, the processor 140 is configured to: control the power supply unit 130 to drive the RF unit 120 at a first driving voltage when the wireless communication electronic device 100 receives a first wireless signal power; and control the power supply unit 130 to drive the RF unit 120 at a second driving voltage different from the first driving voltage when the wireless communication electronic device 100 receives a second wireless signal power.

[0035] In addition, the processor 140 stores a correspondence R1 between power and driving voltage. In this embodiment, the correspondence R1 is, for example, a correspondence between power and driving voltage. The processor 140 is configured to: when the wireless communication electronic device 100 receives a first wireless signal power (for example, the processor 140 obtains the corresponding wireless signal power based on (or calculates) the wireless signal received by the antenna 110), query the first driving voltage Vd1 corresponding to the first wireless signal power based on the correspondence R1; and when the wireless communication electronic device 100 operates at a second wireless signal power, query the second driving voltage Vd2 corresponding to the second wireless signal power based on the correspondence R1.

[0036] In addition, the aforementioned correspondence R1 can be stored in the processor 140. The processor 140 further stores the country code CD and multiple sets of correspondences, one of which corresponds to the country code CD. The multiple sets of correspondences R1 correspond to the communication standards of multiple different countries. The processor 140 is further used to: obtain the country code CD; and obtain the correspondence R1 corresponding to the country code CD among these correspondences. For example, if the country code CD represents Canada, the processor 140 obtains the correspondence corresponding to Canada, and determines the driving voltage corresponding to the wireless signal power based on the selected correspondence. In another embodiment, the processor 140 can store only one set of correspondences R1 corresponding to the country code CD, so that the correspondence R1 can be directly used without obtaining the country code CD separately.

[0037] Please refer to Figure 3 , which is a flowchart of a driving method of a wireless communication electronic device according to another embodiment of the present invention.

[0038] In step S210 , when the wireless communication electronic device 100 receives the first wireless signal power, the processor 140 controls the power supply unit 130 to drive the RF unit 120 with the first driving voltage Vd1 .

[0039] In step S220 , the processor 140 switches the wireless communication electronic device 100 to receive the second wireless signal power and controls the power supply unit 130 to drive the RF unit 120 with a second driving voltage Vd2 , where the second driving voltage Vd2 is different from the first driving voltage Vd1 .

[0040] The other steps of the driving method according to the embodiment of the present invention have been described above and will not be repeated here.

[0041] In summary, although the present invention has been disclosed above with reference to the embodiments, these are not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
