[0001] The present invention relates to a measuring device, and more particularly to a measuring device that measures a radio signal transmitted and received by a communication device operating according to the communication standard of a wireless local area network (LAN).

Summary of the Invention

Problems to be Solved by the Invention

[0006] In recent years, IEEE 802.11be, an extremely high throughput (EHT) wireless LAN standard, has been proposed as the successor to IEEE 802.11ax.

[0007] According to the IEEE 802.11be standard, Capability Element parameters can be set for each MCS (Modulation and Coding Scheme). Therefore, when the measurement device is in AP (Access Point) mode, there are 9 setting items for Capability Element parameters, and when it is in STA (Station) mode, there are 13 items.

[0008] In measuring devices, when setting such parameters, if the MIMO communication parameter settings are displayed below the SISO communication parameter settings, as in conventional methods, then 18 parameter settings will be displayed in AP mode and 26 parameter settings in STA mode. This can lead to a decrease in usability, as users may spend a long time searching for the parameter they want to set or may accidentally set an unintended parameter.

[0009] Therefore, the present invention aims to provide a measuring device that makes the parameter setting screen easier to view, allowing users to easily find the parameters they want to set and thus reducing errors in parameter setting. [Means for solving the problem]

[0010] The present invention relates to a measuring device (1) that measures wireless signals transmitted and received by a communication device (100) to measure the transmission and reception characteristics of the communication device, comprising: a display unit (15) that displays an image; and a control unit (16) that, when measuring communication in accordance with the IEEE802.11be standard, switches the setting screen for Capability Element parameters between a setting screen for SISO communication and a setting screen for MIMO communication and displays them on the display unit.

[0011] This configuration allows the Capability Element parameter settings screen to be switched between a settings screen for SISO communication and a settings screen for MIMO communication. This makes the parameter settings screen easier to view, allowing users to easily find the desired parameter and reduce the likelihood of setting errors.

[0012] Furthermore, in the measuring device of the present invention, the control unit sets the initial values ​​of the settings displayed on the setting screen for SISO communication and the setting screen for MIMO communication to different values.

[0013] This configuration results in different default values ​​being displayed on the settings screen for SISO communication and the settings screen for MIMO communication. Therefore, by looking at the default values, it is possible to determine whether it is the settings screen for SISO communication or MIMO communication.

[0014] Furthermore, the present invention relates to a setting screen display method for a measuring device (1) which includes a display unit (15) for displaying an image and performs measurements on wireless signals transmitted and received by a communication device (100) to measure the transmission and reception characteristics of the communication device, and comprises the steps of, when performing measurements of communication in accordance with the IEEE802.11be standard, displaying a setting screen for SISO communication on the display unit when setting Capability Element parameters for SISO communication, and displaying a setting screen for MIMO communication on the display unit when setting Capability Element parameters for MIMO communication.

[0015] This configuration allows the Capability Element parameter settings screen to be switched between a settings screen for SISO communication and a settings screen for MIMO communication. This makes the parameter settings screen easier to view, allowing users to easily find the desired parameter and reduce the likelihood of setting errors. [Effects of the Invention]

[0016] This invention provides a measuring device that makes the parameter setting screen easier to view, allowing users to easily find the parameters they want to set and thus reducing errors in parameter setting. [Brief explanation of the drawing]

[0017] [Figure 1] Figure 1 is a block diagram of a measuring device according to one embodiment of the present invention. [Figure 2] Figure 2 shows an example of a screen for configuring SISO communication settings for a measuring device according to one embodiment of the present invention. [Figure 3] Figure 3 shows an example of a screen for configuring MIMO communication settings for a measuring device according to one embodiment of the present invention. [Modes for carrying out the invention]

[0018] Hereinafter, a measuring device according to an embodiment of the present invention will be described in detail with reference to the drawings. In Figure 1, a measuring device 1 according to one embodiment of the present invention communicates wirelessly with a communication device 100 and performs various measurements on the wireless signals transmitted and received by the communication device 100. In this embodiment, the measuring device 1 operates as a wireless LAN access point (AP) and the communication device 100 operates as a wireless LAN station (STA), but it is not limited to this, and the measuring device 1 may operate as an STA and the communication device 100 may operate as an AP. The measuring device 1 communicates with the communication device 100 in accordance with the communication standard compliant with IEEE 802.11.

[0019] The measuring device 1 is capable of performing measurements using both the SISO communication method and the MIMO communication method.

[0020] The measurement device 1 is composed of a transmission unit 10, a reception unit 11, a signal generation unit 12, a signal analysis unit 13, an operation unit 14, a display unit 15, and a control unit 16.

[0021] The transmission unit 10 amplifies, frequency-converts, etc. the signal generated by the signal generation unit 12 and transmits it to the communication device 100.

[0022] The reception unit 11 amplifies, frequency-converts, etc. the radio signal received from the communication device 100 and outputs it to the signal analysis unit 13.

[0023] The signal generation unit 12 generates a signal including a control packet and a data packet for communicating with the communication device 100, and transmits it to the communication device 100 via the transmission unit 10.

[0024] The signal analysis unit 13 analyzes the radio signal received from the communication device 100 via the reception unit 11, and performs measurement processing on the transmission and reception characteristics of the communication device 100. The transmission and reception characteristics include the packet error rate, EVM (Error Vector Magnitude), transmission power, etc.

[0025] The operation unit 14 is composed of input devices such as a keyboard, a mouse, a touch panel, etc., and outputs the information input by the operation to the control unit 16.

[0026] The display unit 15 is composed of an image display device such as a liquid crystal display, etc., and displays an image for inputting information necessary for measurement, an image indicating the measurement result, etc.

[0027] The control unit 16 is composed of a computer unit having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, and an input / output port, which are not shown in the figure.

[0028] The ROM and hard disk drive of this computer unit store various control constants and maps, along with a program that allows the computer unit to function as a control unit 16. In other words, the CPU executes the program stored in the ROM and hard disk drive, causing the computer unit to function as a control unit 16. The hard disk drive may be a CF (Compact Flash) card or the like, using flash memory.

[0029] The input / output ports of the control unit 16 are connected to the signal generation unit 12, the signal analysis unit 13, the operation unit 14, and the display unit 15, enabling the control unit 16 and each of these units to transmit and receive signals.

[0030] The measuring device 1 of this embodiment is capable of measuring communications in accordance with the IEEE 802.11be standard. In IEEE 802.11be, the channels with predetermined frequency bandwidths used for communication can be selected from frequencies such as 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 320 MHz.

[0031] In IEEE 802.11be, the Capability Element parameter allows for setting Capabilities for each MCS (Modulation and Coding Scheme). Therefore, when measurement device 1 is in AP mode, there are 9 Capability parameter settings, and when it is in STA mode, there are 13 settings.

[0032] When setting these items in measuring device 1, if the parameter setting items for MIMO mode are displayed below the parameter setting items for SISO mode, as in the conventional method, then the area for setting 18 parameters will be displayed in AP mode, and 26 parameters in STA mode.

[0033] Therefore, the measuring device 1 of this embodiment switches between displaying the Capability Element parameter setting screen for SISO communication and the setting screen for MIMO communication.

[0034] The control unit 16 displays an image on the display unit 15, such as the one shown in Figure 2, as a setting screen for the Capability Element parameters when performing measurements using the SISO communication method, allowing the user to set the Capability Element parameters.

[0035] In Figure 2, the EHT setting unit 101 is an item that allows setting the Capability Element parameter for each MCS, which was added in IEEE802.11be.

[0036] In the EHT setting unit 101, if the channel frequency bandwidth is 20 MHz, the MCS classification can be set to "MCS Index 0-7", "MCS Index 8-9", "MCS Index 10-11", or "MCS Index 12-13". If the channel frequency bandwidth is other than 20 MHz, the MCS classification can be set to "MCS Index 0-9", "MCS Index 10-11", or "MCS Index 12-13".

[0037] In the EHT setting unit 101, as shown in an enlarged view on the right side of Figure 2, each item can be selected as either "Supported" or "Not Supported". The initial value for each item is "Supported".

[0038] The control unit 16 displays an image on the display unit 15, such as the one shown in Figure 3, as a setting screen for the Capability Element parameters when performing measurements using MIMO communication, allowing the user to set the Capability Element parameters.

[0039] In Figure 3, the VHT setting unit 102 is an item that allows setting the MCS of the Capability Element parameter in IEEE802.11ac. In the VHT setting unit 102, "VHT MCS Index 2ss" is a setting item for when performing MIMO communication.

[0040] The HE setting section 103 is an item that allows you to set the MCS of the Capability Element parameter in IEEE802.11ax. In the HE setting section 103, "HE MCS Index 2ss" is a setting item for when performing MIMO communication.

[0041] Thus, with IEEE 802.11ac and IEEE 802.11ax, displaying the MIMO communication settings below the SISO communication settings does not significantly change the appearance or usability.

[0042] In IEEE 802.11be, displaying the MIMO communication settings section with the same amount of information below the SISO communication EHT settings section 101 shown in Figure 2 would increase the number of items, making it difficult to read and worsening usability.

[0043] Therefore, in this embodiment, as shown in Figure 3, only the EHT setting unit 104 for MIMO communication is displayed. Note that the MIMO communication setting values ​​are not used when using SISO communication, and the SISO communication setting values ​​are not used when using MIMO communication, so there is no need to set them.

[0044] The EHT setting unit 104, similar to the EHT setting unit 101 in Figure 2, allows setting the MCS classification to "MCS Index 0-7", "MCS Index 8-9", "MCS Index 10-11", or "MCS Index 12-13" when the channel frequency bandwidth is 20 MHz, and allows setting the MCS classification to "MCS Index 0-9", "MCS Index 10-11", or "MCS Index 12-13" when the channel frequency bandwidth is other than 20 MHz.

[0045] In the EHT setting unit 104, as shown in an enlarged view on the right side of Figure 3, each item can be selected from "1 spatial stream," "2 spatial streams," and "Not Supported." The initial value for each item is "1 spatial stream."

[0046] As described above, in the above embodiment, when the control unit 16 performs a measurement of communication in accordance with the IEEE 802.11be standard, it switches the setting screen for the Capability Element parameter between the setting screen for SISO method communication and the setting screen for MIMO method communication and displays them on the display unit 15.

[0047] This allows the Capability Element parameter settings screen to be switched between a settings screen for SISO communication and a settings screen for MIMO communication. This makes the parameter settings screen easier to view, allowing users to easily find the desired parameter and reducing the likelihood of setting errors.

[0048] Furthermore, the control unit 16 sets the initial values ​​of the settings displayed on the SISO communication setting screen and the MIMO communication setting screen to different values.

[0049] As a result, different default values ​​are displayed on the settings screen for SISO communication and the settings screen for MIMO communication. Therefore, by looking at the default values, it is possible to determine whether it is the settings screen for SISO communication or MIMO communication.
