With the popularization of handheld internet access devices, such as smart phones, tablet computers and other devices, wireless internet access has been widely used. The workplace or the home can use the Wireless router to establish a Wireless Access Point System (WAP System) by itself to connect to the internet or establish a local area network. The antenna of the wireless router usually has directivity, so that the wireless signal has the best signal receiving strength in a specific direction. However, the handheld internet access device can move in different places and cannot be fixed at one place to match a specific direction. Especially, in indoor places, signal shielding objects often shield, refract or reflect wireless signals.
Although the foregoing problem can be solved by enhancing the transmission power, the transmission power is limited by regulations, has a certain upper power limit, and cannot be enhanced without limitation. In another method, a wireless bridge is separately installed to enhance the signal quality for each area and location, but the problem encountered by the wireless router is also encountered by the wireless bridge.

Detailed Description
Referring to fig. 1, a Wireless Access Point System (WAP System) with adjustable antenna orientation according to an embodiment of the present invention includes a Wireless signal base station 100, a location setting module 200, and a mobile electronic device 300. As shown in fig. 2, the mobile electronic device 300 actually moves between a plurality of locations (P1-P6), and the wireless signal transceiving range of the wireless signal base station 100 covers the plurality of locations (P1-P6), but the wireless signal base stations 100 corresponding to each location (P1-P6) may be different; the mobile electronic device 300 can control the wireless access point systems at the locations (P1 to P6) according to the locations (P1 to P6) to adjust the antenna pointing directions of the wireless signal base stations 100. In a specific application example, the wireless signal base station 100 is a home wireless router, and the mobile electronic device 300 is a wireless internet access device; the mobile electronic device 300 is used for establishing a wireless communication link with the wireless signal base station 100. The mobile electronic device 300 includes, but is not limited to, a smart phone, a tablet computer or a notebook computer, and the locations (P1-P6) are different living areas (different rooms) in the home.
As shown in fig. 1, the wireless base station 100 has a directional antenna unit 110 and an antenna adjusting unit 120. The directional antenna unit 110 is configured to emit a base station wireless signal S having a transmission direction V, and the antenna adjustment unit 120 is configured to receive a control command C to adjust the directional antenna unit 110 to adjust the transmission direction V of the base station wireless signal. The manner of adjusting the transmission direction V includes mechanical adjustment and electronic adjustment, depending on the form of the directional antenna unit 110.
As shown in fig. 1 and 3, the location setting module 200 stores a location list 210, and the location list 210 records a plurality of locations (P1 to P6), optimal orientations (Vb1 to Vb6) corresponding to the respective locations (P1 to P6), and optimal signal strengths (SL1 to SL 6).
As shown in fig. 1 and 4, the mobile electronic device 300 has a wireless signal transceiver 310, a signal strength analysis module 320 and an antenna control module 330. The wireless signal transceiver 310 is used for receiving the base station wireless signal S and sending a control command C, and the signal strength analyzing module 320 is connected to the wireless signal transceiver 310 for analyzing the signal receiving strength and the corresponding transmitting direction V of the base station wireless signal S.
The antenna control module 330 is used for receiving the input of a location (P1-P6). The locations are usually detailed information of the current locations (P1 to P6) manually inputted by the user, and may also be detected automatically, for example, Radio Frequency Identification (RFID) tags are set near each of the locations (P1 to P6) for the mobile electronic device 300 to detect to determine the current locations (P1 to P6). Upon manual input by the user, the places (P1-P6) may be selected from a list; for example, when a wireless access point system with adjustable antenna orientation is set up in a home, the home can be planned into different living areas (a plurality of locations P1 to P6), and then the locations are recorded by a selection list (P1 to P6); the user of the mobile electronic device 300 can select the location of the user by selecting the list (P1-P6). The main function of the antenna control module 330 is to issue a control command C to control the antenna adjustment unit 120 to change the transmission direction V, and the modes of the antenna control module 330 controlling the antenna adjustment unit 120 include a detection mode and a connection mode.
As shown in fig. 2 and 3, the detection mode may be activated when the mobile electronic device 300 arrives at a location (P1-P6) that is not in the location list 210. In the detection mode, the antenna control module 330 sends the control command C through the wireless signal transceiver 310 to control the wireless signal base station 100 to send the base station wireless signal S within a specified pointing range and change the transmission direction V, for example, rotate the transmission direction V once horizontally by 360 degrees and rotate the transmission direction V once by 180 degrees. The wireless signal transceiver 310 can continuously receive the base station wireless signal S, or sample the base station wireless signal S at a certain angle difference, and then send the sampled base station wireless signal S to the signal strength analysis module 320. The signal strength analysis module 320 may analyze the base station wireless signals S continuously received, and obtain the transmission direction V having the optimal signal strength (SL1 to SL6) as the optimal direction (Vb1 to Vb6), so as to update the location list 210 of the location setting module 200 corresponding to the optimal direction (Vb1 to Vb6), the corresponding locations (P1 to P6), and the optimal signal strength (SL1 to SL 6). Of course, when the locations (P1-P6) are stored in the location list 210, the mobile electronic device 300 can still automatically or manually initiate the detection mode according to the user operation.
As shown in fig. 2 and 3, when the current locations (P1-P6) are stored in the location list 210, the mobile electronic device 300 can directly perform the connection mode. After the user manually inputs or selects the current location (one of P1 to P6), the antenna control module 330 receives the input of the current location (P1 to P6), and loads the best direction (Vb1 to Vb6) corresponding to the current location (P1 to P6) from the location list 210 of the location setting module 200 according to the input of the current location (P1 to P6), and sends a control command C to control the directional antenna 112a to transmit the base station wireless signal S, so as to adjust the transmission direction V to the loaded best direction (Vb1 Vb to 6).
Referring to fig. 5, in one or more embodiments of the present invention, the directional antenna unit 110 includes two or more directional antennas 112a, and each of the directional antennas 112a has a fixed transmission direction V or can change the transmission direction V on different reference planes (e.g., horizontal plane and vertical plane). Such a directional antenna 112a may be a PCB PIFA (printed circuit board inverted-F antenna), or other antenna, such as: a Dipole antenna or a Monopole antenna. The plurality of directional antennas 112a are connected to the antenna adjustment unit 120. The antenna adjusting unit 120 switches the antenna position through the multiplexing control circuit, so as to adjust the signal output of the directional antenna 112a, such as the signal strength and the direction of each antenna, to provide the base station wireless signal S and the transmission direction V.
Referring to fig. 6, in one or more embodiments of the present invention, the directional antenna unit 110 is a mechanical directional antenna unit, the directional antenna unit 110 is a directional antenna, and the antenna adjusting unit 120 is a single-axis or multi-axis rotating base for carrying the directional antenna and adjusting the transmission direction V of the base station wireless signal S emitted by the directional antenna.
As shown in fig. 7 and 8, the location setting module 200 mainly stores the location list 210, and the location list 210 can be updated or loaded into the mobile electronic device 300.
As shown in fig. 7, in one or more embodiments of the present invention, the location setting module 200 is integrated with the wireless signal base station 100. The combination method can be a built-in software or hardware module, or an external removable storage device. After the mobile electronic device 300 establishes a wireless communication link with the wireless signal base station 100, the mobile electronic device 300 obtains the location list 210 through the wireless signal base station 100 by wireless transmission. In the embodiment of fig. 9, the location setting module 200 may store a plurality of location lists 210, which belong to different mobile electronic devices 300 respectively.
As shown in fig. 8, in one or more embodiments of the present invention, the location setting module 200 is integrated with the mobile electronic device 300, and stores a location list 210 specific to the mobile electronic device 300 itself, but the location list 210 may include transmission direction V settings of different wireless signal base stations 100. Therefore, the embodiment of fig. 8 provides a mobile electronic device 300 capable of controlling the direction of the wireless signal base station 100, which comprises a wireless signal transceiver 310, a signal strength analysis module 320, a location setting module 200 and an antenna control module 330, wherein the antenna control module 330 has a detection mode and a connection mode. In the embodiment of fig. 8, the location setting module 200 can be a software or hardware module built in the mobile electronic device 300, or can be an external removable storage device. In fact, the signal strength analysis module 320, the antenna control module 330 and the location setting module 200 can be built by software modules, so as to be integrated into a single application software installed in the mobile electronic device 300, so as to call the wireless signal transceiver 310 and other hardware resources of the mobile electronic device 300 to build corresponding software modules.
Referring to fig. 9, one or more embodiments of the invention further disclose a method for optimizing antenna directivity of a wireless signal base station 100, which steps are described as follows.
First, when the mobile electronic device 300 enters the transmission range of the radio base station 100, the mobile electronic device 300 may send an initialization signal through the radio transceiver 310 to perform a handshake procedure with the radio base station 100 to establish a communication connection, thereby initializing a connection between the mobile electronic device 300 and the radio base station 100, as shown in Step 101.
Next, the mobile electronic device 300 receives a base station wireless signal S transmitted by a wireless base station 100, as shown in Step 110. The foregoing base station wireless signal S includes parameters related to signal transmission, such as reference signal strength, transmission direction V, and the like.
Then, based on the user input or other location detection means, the mobile electronic device 300 receives an input of a location (P1-P6), and updates the location (P1-P6) in a location list 210, as shown in Step 120. The execution sequence of steps 110 and 120 can be changed arbitrarily, even executed simultaneously. The updating of the locations (P1 to P6) in the location list 210 means to confirm whether there is a match with the current locations (P1 to P6) in the locations (P1 to P6) recorded in the location list 210, and if not, write the current locations (P1 to P6) into the location list 210 as a record of one location (P1 to P6).
The mobile electronic device 300 executes the detection mode. The mobile electronic device 300 issues a control command C to control the base station 100 to issue the base station wireless signal S within a specified pointing range and change the transmission direction V, as shown in Step 130. The designated pointing range may be a range of angles set in the vertical and horizontal directions, or may be a range that is completely changed within the maximum range in which the transmission pointing direction V can be changed (for example, 180 degrees vertically and 360 degrees horizontally). The transmit pointing V parameter may be encapsulated in a data packet and sent with the base station radio signal S.
While the wireless signal base station 100 continuously sends out the base station wireless signal S and changes the transmission direction V, the mobile electronic device 300 receives the base station wireless signal S with the wireless signal transceiver 310 and transmits to the signal strength analysis module 320. After receiving the base station wireless signal S, the signal strength analyzing module 320 analyzes the transmission direction V from the data packet to analyze the signal receiving strength of the base station wireless signal S and the corresponding transmission direction V. Finally, the signal strength analyzing module 320 obtains the best direction Vb with the best signal receiving strength from the plurality of signal receiving strengths and the corresponding transmitting directions V, as shown in Step 140.
Finally, the signal strength analysis module 320 updates the optimal pointing Vb from the location list 210, and establishes a corresponding relationship between the optimal pointing Vb and the current location (P1 to P6) in the location list 210, as shown in Step 150.
Through the steps from Step 110 to Step 150, the mobile electronic device 300 can complete the execution of the detection mode.
Referring to fig. 10, in one or more embodiments of the present invention, Step 120 may be further subdivided into the following sub-steps.
After receiving the input of the places (P1-P6), it is compared whether the places (P1-P6) exist in the place list 210, as shown in Step 122.
In the Step 122 comparison, if the location (P1-P6) is not in the location list 210, the following steps are continued, (steps after Step 130 are performed) to complete the detection mode.
In the Step 122, if the location (P1-P6) is in the location list 210, the detection mode is stopped, and the connection mode is started.
Referring to fig. 11 and 12, in the link mode, according to the input of the locations (P1-P6), the best direction Vb of the corresponding location (P1-P6) is loaded from the location list 210, as shown in Step 210. The base station 100 then controls the wireless signal to adjust the transmitting direction V to the loaded optimal direction Vb, as shown in Step 220.
As shown in fig. 10, 11 and 12, the complete link mode actually starts from Step 101. Therefore, if the input locations (P1-P6) are not in the location list 210, the Step 122 goes to Step 130, and the detection mode is executed instead, i.e., the steps after Step 130 are executed.
As shown in fig. 10, fig. 11 and fig. 12, in practice, after Step 150, the connection start mode may be executed directly, and the base station 100 is controlled to adjust the transmission direction V to the loaded optimal direction Vb.
As shown in fig. 12, in addition to the locations (P1-P6), the optimal directions (Vb 1-Vb 6) corresponding to the respective locations (P1-P6) and the optimal signal strengths (SL 1-SL 6), the location list 210 further records a number of using locations (Fr 1-Fr 6) for the mobile electronic device 300 and the wireless base station 100 to establish the wireless communication link at each location. Before the detection mode is performed, i.e., before the reception sites (P1 to P6) are inputted, the base station 100 loads the corresponding optimal orientations (Vb1 to Vb6) and adjusts the transmission orientations of the base station radio signals according to the sites (P1 to P6) where the number of times of using the sites (Fr1 to Fr6) is the highest.
As shown in fig. 13, the antenna control module 330 of the mobile electronic device 300 can directly load the optimal directivity (Vb1 to Vb6) through the location list 210 and the input locations (P1 to P6), and control the directional antenna 112a of the base station 100 to adjust the transmission directivity V to the loaded optimal directivity (Vb1 to Vb 6). The antenna control module 330 of the mobile electronic device 300 can still control the directional antenna 112a of the base station 100 to change the transmission direction V within an auxiliary directional range based on the optimal directional directions (Vb 1-Vb 6), as shown in Step 230. The auxiliary pointing range refers to a small amplitude change in the transmission pointing direction V, for example, a small angle (for example, not more than 45 degrees) in the horizontal and elevation directions with respect to the optimum pointing direction (Vb1 to Vb 6). Then the mobile electronic device 300 uses the signal strength analysis module 320 to analyze whether the signal reception strength of another transmission point V in the auxiliary pointing range is better than the optimal pointing direction (Vb 1-Vb 6), as shown in Step 240; if so, the best beacon Vb and the best signal strength (SL1 to SL6) are replaced by another transmitted beacon V and the corresponding signal strength, and the location list 210 is updated, as shown in Step 250, so as to ensure that each of the best beacons (Vb1 to Vb6) can be updated at any time and maintained in the best state, in response to the situation that the transceiving characteristics of the base station 100 or the mobile electronic device 300 may change with the changes of software and hardware and the changes of environment.
As shown in fig. 12 and 14, in the detection mode, when the antenna control module 330 updates the location list 210 of the location setting module 200 with the optimal direction (Vb 1-Vb 6) and a corresponding location (P1-P6), the corresponding rssi (SL 1-SL 6) is written into the location list 210 at the same time. In the connection mode, after the transmission direction V of the base station wireless signal S is adjusted to the loaded optimal direction (Vb1 to Vb6) (Step 220), the signal strength analysis module 320 of the mobile electronic device 300 can still analyze whether the difference between the actual signal received strength and the signal received strength (SL1 to SL6) corresponding to the optimal direction (Vb1 to Vb6) is greater than a threshold value (Step 260). If the difference is greater than the threshold value, which indicates that the original best direction (Vb 1-Vb 6) is not applicable, the mobile electronic device 300 re-obtains the best direction (Vb 1-Vb 6) with the best rssi, i.e., the Step 130 starts to perform the detecting mode.
Referring to fig. 15 and 16, if the difference is greater than the threshold value in Step260, the information of the received signal strength (SL1 to SL6) may also be output and displayed on the display interface of the mobile electronic device 300, as shown in Step 272. The displayed information may also include other information, as shown in fig. 16, including the names of the base stations 100, transmission rates, signal reception strengths, traffic, connection times, and the number of times of use points (Fr1 to Fr 6).
