Embodiments for Carrying Out the Invention

[0014] First, the background leading to the present invention will be described. FIG. 10 is a diagram showing an example of the use of a radio wave information measurement system. As shown in FIG. 10, in the radio wave information measurement system, for example, radio wave information regarding radio waves transmitted by each of a plurality of base stations 10 arranged in a predetermined area 1 indoors or outdoors is measured by, for example, three engineers (users) using radio terminals 12-1 to 12-3 that communicate with the base stations 10 via, for example, a wireless LAN, and the measurement results are transmitted to the server device 14. Note that the number of base stations and the number of radio terminals (the number of users) are each arbitrary numbers, but here they are each set to 3.

[0015] The base stations 10 are selected for the number of installations, installation locations, and radio wave measurement points (measurement positions) based on the drawing of a predetermined area 1 (for example, a floor) that is the target for constructing a wireless LAN by a senior engineer with the skills necessary for constructing a wireless network.

[0016] The radio terminals 12-1 to 12-3 are used as a site survey tool that detects, for example, RSSI (Received Signal Strength Indicator) as information regarding radio waves transmitted by each of the base stations 10.

[0017] Each engineer (user) determines the measurement position of the radio waves in charge and causes the site survey tool (radio terminal) to read the drawing of the floor in charge. Then, each engineer sequentially moves to the measurement position of the radio waves in charge, measures the radio wave information using the site survey tool, and transmits the measurement results to the server device 14. The server device 14 visualizes and displays the radio wave information transmitted from each site survey tool.

[0018] FIG. 11 is a diagram showing a specific configuration example of the radio wave information measurement system. The radio wave information measurement system includes, for example, radio terminals 12-1 to 12-3 and a server device 14. Note that when not specifying any one of the configurations having a plurality such as the radio terminals 12-1 to 12-3, it is simply abbreviated as the radio terminal 12 or the like.

[0019] The wireless terminal 12 has a setting unit 15, an operation unit 16, a detection unit 17, and a transmission unit 18 respectively. The setting unit 15 performs settings for the wireless terminal 12. For example, according to the operations of the operation unit 16 by the user, the setting unit 15 captures the drawing of the floor where the site survey is to be carried out into the wireless terminal 12.

[0020] The operation unit 16 is a user interface that accepts user operations. For example, when the user moves to the radio wave measurement position and clicks on the drawing that coincides with their current location, the detection unit 17 is caused to start operating.

[0021] When there is a user click on the operation unit 16, the detection unit 17 starts measuring radio wave information. For example, the detection unit 17 performs a channel scan, detects the RSSI of the radio waves transmitted by the base station 10, etc., and outputs it to the transmission unit 18.

[0022] The transmission unit 18 transmits radio wave information such as the RSSI detected by the detection unit 17 to the server device 14.

[0023] Then, the user moves to other measurement positions, similarly operates the operation unit 16, measures the radio wave information by the wireless terminal 12, and repeats the operation of transmitting the measurement results to the server device 14 within the predetermined area 1.

[0024] The server device 14 has, for example, a reception unit 140 and a visualization unit 142. The reception unit 140 receives the radio wave information measured by each user at a plurality of measurement positions respectively, and outputs it to the visualization unit 142. The visualization unit 142 visualizes the radio wave state in the entire predetermined area 1 based on the radio wave information input from the reception unit 140.

[0025] When each user conducts a site survey, it is desirable for them to enthusiastically acquire the skills necessary for building a wireless network. Here, acquiring the skills necessary for building a wireless network is considered to be in agreement with the fact that when the user looks at the drawing of the predetermined area 1 and if the base station 10 is installed at this position, it can be predicted that the maximum value of the received signal strength (RSSI) will be around this value at a certain point (measurement position).

[0026] Therefore, the radio wave information measurement system according to one embodiment is configured such that game elements are added and it is possible to improve the user's motivation to acquire the skills necessary for building a wireless network.

[0027] FIG. 1 is a functional block diagram illustrating the functions of the wireless terminal 2 included in the radio wave information measurement system according to one embodiment. FIG. 2 is a functional block diagram illustrating the functions of the server device 3 included in the radio wave information measurement system according to one embodiment. A plurality of wireless terminals 2 and the server device 3 are used in place of the wireless terminals 12-1 to 12-3 and the server device 14 within the predetermined area 1 shown in FIG. 10 to constitute the radio wave information measurement system according to one embodiment.

[0028] As shown in FIG. 1, the wireless terminal 2 serving as a client has a setting unit 20, an operation unit 21, a detection unit 22, a transmission unit 23, a reception unit 24, and a display unit 25.

[0029] The setting unit 20 takes in the drawing of the floor on which the site survey is to be carried out into the wireless terminal 2 in response to an operation on the operation unit 21 by the user.

[0030] The operation unit 21 is a user interface such as a touch panel capable of displaying a drawing, for example, that accepts the user's operation. For example, when the user moves to the radio wave measurement position and clicks on the drawing that coincides with their current location, the detection unit 22 is caused to start operating.

[0031] When there is a click by the user on the operation unit 21, the detection unit 22 starts measuring radio wave information. For example, the detection unit 22 performs channel scanning, detects (measures) the RSSI and the like of the radio waves transmitted by each of the plurality of base stations 10, and outputs the detected results to the transmission unit 23 as radio wave information.

[0032] The transmission unit 23 transmits the radio wave information such as the RSSI detected by the detection unit 22 to the server device 3.

[0033] Then, the user moves to another measurement position, similarly operates the operation unit 21, measures the radio wave information by the wireless terminal 2, and repeats the operation of transmitting the measurement results to the server device 3 within the predetermined area 1.

[0034] The reception unit 24 receives the information transmitted by the server device 3 and outputs it to the display unit 25.

[0035] The display unit 25 displays the information received by the reception unit 24. For example, the display unit 25 displays the scores (described later) of a plurality of users transmitted by the server device 3 respectively.

[0036] Also, as shown in FIG. 2, the server device 3 includes a storage unit 30, a reception unit 31, a visualization unit 32, a game execution unit 33, and a transmission unit 34.

[0037] The storage unit 30 stores the predicted values of the radio wave information predicted by each of the plurality of users when measured at each of the plurality of measurement positions preset within the predetermined area 1. For example, each user predicts the maximum value of the RSSI predicted when measured at each of the plurality of measurement positions. Specifically, the storage unit 30 stores an electronic file in which the user name, the measurement position (detection position), and the predicted value are described.

[0038] The reception unit 31 receives the measured values of the radio wave information detected (measured) by each of the wireless terminals 2 at each of the plurality of measurement positions, and outputs them to the visualization unit 32 and the game execution unit 33.

[0039] The visualization unit 32 visualizes the radio wave state throughout a predetermined area 1 based on the radio wave information input from the reception unit 31.

[0040] The game execution unit 33 includes a difference calculation unit 330, an accumulation value calculation unit 332, and a score calculation unit 334. It accesses the storage unit 30, executes the main processes of the game in the radio wave information measurement system, and outputs the processing results to the transmission unit 34.

[0041] The difference calculation unit 330 calculates, for each user, the difference between the predicted value stored in the storage unit 30 and the measured value received by the reception unit 31 for each of a plurality of measurement positions, and outputs the calculation result to the accumulation value calculation unit 332.

[0042] The accumulation value calculation unit 332 calculates, for each user, the cumulative value of the differences calculated by the difference calculation unit 330 for each of a plurality of measurement positions, and outputs the calculation result to the score calculation unit 334.

[0043] The score calculation unit 334 calculates, for each user, a score such that the smaller the cumulative value calculated by the accumulation value calculation unit 332, the larger the score value, and outputs the calculation result to the transmission unit 34.

[0044] The transmission unit 34 transmits the scores of a plurality of users calculated by the score calculation unit 334 to each of the wireless terminals 2.

[0045] That is, each user (each engineer) will participate in a game in which the scores of each user transmitted from the server device 3 are displayed on the wireless terminal 2 respectively. At this time, each user can know what scores other users have, and it is possible to compete with other users in terms of scores.

[0046] Next, a specific example of the processing performed by the radio wave information measurement system according to an embodiment will be described. FIG. 3 is a flowchart illustrating the processing executed by the game execution unit 33 of the server device 3.

[0047] As shown in FIG. 3, the game execution unit 33 first obtains the maximum value (RSSI_max) of the RSSI at each measurement position of each user by using the RSSI transmitted from the wireless terminal 2 (S100). For example, when the reception unit 31 receives the RSSIs of K base stations 10 from one wireless terminal 2 that the game execution unit 33 has, the game execution unit 33 obtains the maximum value RSSI_max from among the K RSSIs.

[0048] Next, the game execution unit 33 updates the value of the point P_i owned by each engineer i (1 ≦ i ≦ N) in order from engineer 1 (S102) as follows.

[0049] For example, the game execution unit 33 determines whether i ≦ N (S104). If i ≦ N (S104: Yes), the process proceeds to the process of S106. If i ≦ N is not satisfied (S104: No), the process ends.

[0050] In step 106 (S106), the game execution unit 33 performs the operation of the following equation (1).

[0051] P_i = P_i - abs(RSSI_i_A - RSSI_max) ···(1)

[0052] Here, RSSI_i_A is the RSSI value predicted by engineer i at the measurement position A. abs() is a function that returns the absolute value.

[0053] Then, the game execution unit 33 sets engineer i = i + 1 (S108) and returns to the process of S104.

[0054] Thereafter, the server device 3 transmits P_i (1 ≦ i ≦ N) to each of the N wireless terminals 2 used by each user participating in the game.

[0055] When the reception unit 24 of each wireless terminal 2 receives P_i, it outputs the value of P_i to the display unit 25. Each display unit 25 of the wireless terminals 2 displays the game screen shown in FIG. 4.

[0056] In the above formula (1), the absolute value of the difference between the predicted value predicted by the user and the actual measured value is subtracted from the user's points. That is, the more remaining points (scores) a user has, the better the user can predict the radio wave information.

[0057] In this way, by displaying the points of each user on the display unit 25 of the wireless terminal 2 as a game screen respectively, each user can improve the willingness to learn the necessary skills through the game.

[0058] Next, an example of the case where a plurality of users execute a game by the radio wave information measurement system will be described with reference to FIGS. 5 to 8. Here, it is assumed that three users (X, Y, Z) each use one of three wireless terminals 2-1 to 2-3, and four or more base stations 10 are installed. Note that X, Y, and Z may be processed assuming that their values are 1, 2, and 3 respectively.

[0059] As shown in FIG. 5, user X clicks on the operation unit 21 at the timing of 1 second at point A-1 which is the measurement position. User Y clicks on the operation unit 21 at the timing of 2 seconds at point B-1 which is the measurement position. User Z clicks on the operation unit 21 at the timing of 3 seconds at point C-1 which is the measurement position.

[0060] FIG. 6 is a diagram showing the predicted values of each user at their respective measurement positions. FIG. 7 is a diagram illustrating the RSSI values detected (measured) by the wireless terminal 2. FIG. 7(a) is a diagram illustrating the RSSI value detected (measured) by the wireless terminal 2-1. FIG. 7(b) is a diagram illustrating the RSSI value detected (measured) by the wireless terminal 2-2. FIG. 7(c) is a diagram illustrating the RSSI value detected (measured) by the wireless terminal 2-3.

[0061] At t = 1 second, when user X clicks on the drawing of the operation unit 21 of the wireless terminal 2 that coincides with his current location A-1, the detection unit 22 executes a channel scan to detect (measure) the radio wave information shown in FIG. 6. The transmission unit 23 transmits the radio wave information (RSSI) that is the measurement result and the measurement position number (A-1) to the server device 3.

[0062] The receiving unit 31 of the server device 3 outputs the received radio wave information to the visualization unit 32 and the game execution unit 33.

[0063] The game execution unit 33 calculates P_i according to the flowchart shown in FIG. 3. Here, assume that the initial value of P_i is, for example, 100.

[0064] When the server device 3 receives the RSSI of the radio waves transmitted by the three base stations 10 as shown in FIG. 7(a), it obtains the maximum value RSSI_max from the three RSSIs. Here, the maximum value RSSI_max is -40.

[0065] The server device 3 updates the points P_1, P_2, and P_3 as follows respectively.

[0066] P_1 = 100 - abs{(-50) - (-40)} = 90 P_2 = 100 - abs{(-60) - (-40)} = 80 P_3 = 100 - abs{(-55) - (-40)} = 85

[0067] Then, the server device 3 transmits P_i (1 ≤ i ≤ 3) to each of the three wireless terminals 2 used by the users participating in the game.

[0068] When the receiving unit 24 of the wireless terminal 2 receives P_i (1 ≤ i ≤ 3), it outputs the value of P_i to the display unit 25. At this time, the display unit 25 of the wireless terminal 2 displays the game screen illustrated in FIG. 8.

[0069] At t = 2 seconds, when user Y clicks on the screen of the operation unit 21 of the wireless terminal 2 that coincides with his current location B-1, the detection unit 22 executes a channel scan and detects (measures) the radio wave information shown in Fig. 6. The transmission unit 23 transmits the radio wave information (RSSI), which is the measurement result, and the measurement position number (B-1) to the server device 3.

[0070] The game execution unit 33 calculates P_i according to the flowchart shown in Fig. 3.

[0071] When the server device 3 receives the RSSI of the radio waves transmitted by the two base stations 10 as shown in Fig. 7(b), it obtains the maximum value RSSI_max from the two RSSIs. Here, the maximum value RSSI_max is -50.

[0072] The server device 3 updates the points P_1, P_2, and P_3 as follows, respectively.

[0073] P_1 = 90 - abs{(-60) - (-50)} = 80 P_2 = 80 - abs{(-50) - (-50)} = 80 P_3 = 85 - abs{(-45) - (-50)} = 80

[0074] Then, the server device 3 transmits P_i (1 ≤ i ≤ 3) to each of the three wireless terminals 2 used by the users participating in the game.

[0075] When the receiving unit 24 of the wireless terminal 2 receives P_i (1 ≤ i ≤ 3), it outputs the value of P_i to the display unit 25. At this time, the display unit 25 of the wireless terminal 2 displays the game screen illustrated in Fig. 8.

[0076] At t = 3 seconds, when user Z clicks on the screen of the operation unit 21 of the wireless terminal 2 that coincides with his current location C-1, the detection unit 22 executes a channel scan and detects (measures) the radio wave information shown in Fig. 6. The transmission unit 23 transmits the radio wave information (RSSI), which is the measurement result, and the measurement position number (C-1) to the server device 3.

[0077] The game execution unit 33 calculates P_i according to the flowchart shown in FIG. 3.

[0078] When the server device 3 receives the RSSIs of the radio waves transmitted by the four base stations 10 as shown in FIG. 7(c), it obtains the maximum value RSSI_max from among the four RSSIs. Here, the maximum value RSSI_max is -40.

[0079] The server device 3 updates the points P_1, P_2, and P_3 as follows, respectively.

[0080] P_1 = 80 - abs{(-55) - (-40)} = 65 P_2 = 80 - abs{(-45) - (-40)} = 75 P_3 = 80 - abs{(-50) - (-40)} = 70

[0081] Then, the server device 3 transmits P_i (1 ≤ i ≤ 3) to each of the three wireless terminals 2 used by each user participating in the game.

[0082] When the receiving unit 24 of the wireless terminal 2 receives P_i (1 ≤ i ≤ 3), it outputs the value of P_i to the display unit 25. At this time, the display unit 25 of the wireless terminal 2 displays the game screen illustrated in FIG. 8.

[0083] As described above, in the radio wave information measurement system according to the embodiment, since game elements are added to each of the wireless terminals 2 used by each user, it is possible to motivate users to acquire the skills necessary for constructing a wireless network while measuring radio wave information in the construction of the wireless network.

[0084] Note that each function of the wireless terminal 2 and the server device 3 may be partially or entirely configured by hardware such as a PLD (Programmable Logic Device) or an FPGA (Field Programmable Gate Array), or may be configured as a program executed by a processor such as a CPU.

[0085] For example, the server device 3 can be realized using a computer and a program, and it is also possible to record the program on a storage medium or provide it through a network.

As shown in FIG. 9, the server device 3 includes an input unit 50, an output unit 51, a communication unit 52, a CPU 53, a memory 54, and an HDD 55 connected via a bus 56, and has functions as a computer. Also, the server device 3 is capable of inputting and outputting data to and from a computer-readable storage medium 57.
