Description

Technical Field

[0001] This invention relates to a measuring device, and more particularly to a measuring device for measuring wireless signals transmitted and received by a communication device operating according to the wireless LAN (Local Area Network) communication standard. Background Technology

[0002] With the development of information and communication technology, various wireless communication technologies have been developed. Among them, communication standards related to wireless LAN technology include, for example, IEEE (Institute of Electrical and Electronics Engineers) 802.11ac (VHT: Very High Throughput) and IEEE 802.11ax (HE: High Efficiency).

[0003] In wireless communication in wireless LANs, there are SISO (Single Input Single Output) mode, where both the transmitting and receiving sides communicate using a single antenna, and MIMO (Multiple Input Multiple Output) mode, where both the transmitting and receiving sides communicate using multiple antennas.

[0004] Patent document 1 describes the measurement of a measured device using multiple measuring devices in a SISO manner to perform MIMO-based communication.

[0005] Patent Document 1: Japanese Patent No. 6672554

[0006] In recent years, as the next version of IEEE 802.11ax, the Extremely High Throughput (EHT) wireless LAN standard, namely IEEE 802.11be, has been proposed.

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

[0008] In the measurement device, when setting up such items, as in the past, when setting up the parameters for SISO communication is displayed below the parameters for MIMO communication, 18 parameters are displayed in AP mode and 26 parameters are displayed in STA mode. As a result, users have to spend time finding the parameters to be set or set unexpected parameters, which reduces the availability. Summary of the Invention

[0009] Therefore, the object of the present invention is to provide a measuring device that makes the parameter setting screen easy to view and the parameter to be set easy to find, and can suppress parameter setting errors.

[0010] The measuring device of the present invention includes: a display unit 15 for displaying an image; and a control unit 16 for displaying the image on the display unit. The measuring device 1 measures the transceiver characteristics of the communication device by measuring wireless signals transmitted and received by the communication device 100. In the case of measuring communication according to the IEEE (Institute of Electrical and Electronics Engineers) 802.11be standard, the control unit switches between setting screens for capability element parameters in SISO (Single Input Single Output) mode and MIMO (Multiple Input Multiple Output) mode and displays them on the display unit.

[0011] According to this structure, the setting screen for capability element parameters switches between and displays a setting screen for communication in SISO mode and a setting screen for communication in MIMO mode. Therefore, the parameter setting screen is easy to view, making it easy to find the parameter to be set, and it can suppress parameter setting errors.

[0012] Furthermore, in the measuring device of the present invention, the initial value of the setting value displayed by the control unit in the communication setting screen of SISO mode is different from the initial value of the setting value displayed in the communication setting screen of MIMO mode.

[0013] Based on this structure, different initial values ​​are displayed on the communication setup screens for SISO and MIMO modes. Therefore, by viewing the initial values, it is possible to distinguish between the SISO and MIMO communication setup screens.

[0014] Furthermore, in the measuring device of the present invention, the selectable values ​​of the setting value displayed by the control unit in the communication setting screen of SISO mode are different from the selectable values ​​of the setting value displayed in the communication setting screen of MIMO mode.

[0015] Furthermore, the setting screen display method of the present invention is a setting screen display method for a measuring device 1. The measuring device 1 includes a display unit 15 for displaying images and measures the transmission and reception characteristics of the communication device by measuring the wireless signals transmitted and received by the communication device 100. In the case of measuring communication according to the IEEE 802.11be standard, the setting screen display method includes the following steps: when setting the communication capability element parameters of SISO mode, displaying the communication setting screen of SISO mode on the display unit; and when setting the communication capability element parameters of MIMO mode, displaying the communication setting screen of MIMO mode on the display unit.

[0016] According to this structure, the setting screen for capability element parameters switches between and displays a setting screen for communication in SISO mode and a setting screen for communication in MIMO mode. Therefore, the parameter setting screen is easy to view, making it easy to find the parameter to be set, and it can suppress parameter setting errors.

[0017] Furthermore, in the setting screen display method of the present invention, the control unit sets different initial values ​​for the setting values ​​displayed in the setting screen for communication in SISO mode and the initial values ​​for the setting values ​​displayed in the setting screen for communication in MIMO mode.

[0018] Furthermore, in the setting screen display method of the present invention, the control unit sets different values ​​for the selectable values ​​of the setting values ​​displayed in the SISO mode communication setting screen and the selectable values ​​of the setting values ​​displayed in the MIMO mode communication setting screen.

[0023] Figure 3This is an example of a screen showing the settings for MIMO communication of a measuring device according to an embodiment of the present invention. Detailed Implementation

[0024] Hereinafter, the measuring device according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] exist Figure 1 In one embodiment of the present invention, the measuring device 1 communicates wirelessly with the communication device 100 to perform various measurements on the wireless signals transmitted and received by the communication device 100. In this embodiment, the measuring device 1 is configured to operate as a wireless LAN host (AP: Access Point), and the communication device 100 is configured to operate as a wireless LAN extension (STA: STAtion), but this is not a limitation; the measuring device 1 may also operate as a STA, and the communication device 100 as an AP. Furthermore, the measuring device 1 communicates with the communication device 100 according to the IEEE 802.11-based communication standard.

[0026] The measuring device 1 can perform measurements of communication in SISO mode as well as measurements of communication in MIMO mode.

[0027] The measuring device 1 comprises a transmitting unit 10, a receiving unit 11, a signal generating unit 12, a signal analyzing unit 13, an operating unit 14, a display unit 15, and a control unit 16.

[0028] The transmitting unit 10 amplifies or frequency-converts the signal generated by the signal generating unit 12 and transmits it to the communication device 100.

[0029] The receiving unit 11 amplifies or frequency-converts the wireless signal received from the communication device 100 and outputs it to the signal analysis unit 13.

[0030] The signal generation unit 12 generates a signal including a control packet or data packet for communicating with the communication device 100, and transmits it to the communication device 100 via the transmission unit 10.

[0031] The signal analysis unit 13 analyzes the wireless signal received from the communication device 100 via the receiving unit 11 and performs measurement processing on the transmission and reception characteristics of the communication device 100. These transmission and reception characteristics include packet error rate, EVM (Error Vector Magnitude), and transmission power.

[0032] The operation unit 14 consists of input devices such as a keyboard, mouse and touch panel, and outputs operation input information to the control unit 16.

[0033] The display unit 15 is composed of an image display device such as a liquid crystal display, and displays images that show information required for input measurement or images that represent measurement results.

[0034] The control unit 16 is composed of a computer unit (not shown) equipped with a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), a hard disk device, and input / output ports.

[0035] The ROM and hard disk drive of this computer unit store programs for enabling the computer unit to function as the control unit 16, along with various control constants and mapping diagrams. That is, the computer unit functions as the control unit 16 by executing the programs stored in the ROM and hard disk drive via the CPU. Alternatively, the hard disk drive may be a flash memory-based CF (Compact Flash) card, etc.

[0036] 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, and the control unit 16 can transmit and receive signals with each unit.

[0037] The measuring device 1 of this embodiment is capable of measuring communications according to the IEEE 802.11be standard. Under IEEE 802.11be, the channel with a specified bandwidth for communication can be selected as 20MHz, 40MHz, 80MHz, 160MHz, 320MHz, etc.

[0038] Under IEEE 802.11be, capability parameters can be set for each MCS (Modulation and Coding Scheme). Therefore, when measuring device 1 is in AP mode, there are 9 capability parameter settings, and when measuring device 1 is in STA mode, there are 13 settings.

[0039] In the measuring device 1, when setting such items, as in the past, when setting the parameters for SISO is displayed below the parameters for MIMO, in AP mode, an area for setting parameters for 18 items is displayed, and in STA mode, an area for setting parameters for 26 items is displayed.

[0040] Therefore, the measuring device 1 of this embodiment switches and displays the setting screen for capability element parameters as a communication setting screen in SISO mode and a communication setting screen in MIMO mode.

[0041] Control unit 16, for example, will... Figure 2 The image shown is displayed on the display unit 15 as a setting screen for capability element parameters when performing measurements in SISO mode communication, so as to set the capability element parameters.

[0042] exist Figure 2 In this section, the EHT setting unit 101 is a setting item for each MCS that performs additional capability element parameters under IEEE 802.11be.

[0043] In the EHT setting unit 101, when the channel bandwidth is 20MHz, the MCS classification can be set as "MCS Index 0-7", "MCS Index 8-9", "MCS Index 10-11", and "MCS Index 12-13". When the channel bandwidth is other than 20MHz, the MCS classification can be set as "MCS Index 0-9", "MCS Index 10-11", and "MCS Index 12-13".

[0044] In the EHT setting section 101, such as Figure 2 As shown in the enlarged view on the right, each item allows you to select either "Supported" or "Not Supported". Additionally, the initial value for each item is "Supported".

[0045] Control unit 16, for example, will... Figure 3 The image shown is displayed on the display unit 15 as a setting screen for capability element parameters when performing measurements in MIMO communication, so as to set the capability element parameters.

[0046] exist Figure 3 In this configuration, the VHT setting unit 102 is used to set the MCS (Multi-Side Components) of the capability element parameters under IEEE 802.11ac. Within the VHT setting unit 102, the "VHT MCS index 2ss" is a setting used when performing MIMO (Multi-Match) communication.

[0047] HE setting unit 103 is used to set the MCS (Multi-Side Components) of capability element parameters under IEEE 802.11ax. In HE setting unit 103, "HE MCS index 2ss" is a setting used when performing MIMO (Multi-Match) communication.

[0048] Thus, under IEEE 802.11ac or IEEE 802.11ax, even if the MIMO communication settings are displayed below the SISO communication settings, the appearance will not change much, and the operability will not change either.

[0049] Under IEEE 802.11be, if in Figure 2 If the SISO communication EHT setting unit 101 displays the same amount of information as the MIMO communication setting unit below it, the number of items increases, making it difficult to view and reducing operability.

[0050] Therefore, in this embodiment, as Figure 3 As shown, only the EHT setting unit 104 for MIMO communication is displayed. Furthermore, the settings for MIMO communication are not used during SISO communication, nor are the settings for SISO communication, therefore no settings are required.

[0051] and Figure 2 Similarly, the EHT setting unit 104 can set the MCS classification as "MCS index 0-7", "MCS index 8-9", "MCS index 10-11", and "MCS index 12-13" when the channel bandwidth is 20MHz, and can set the MCS classification as "MCS index 0-9", "MCS index 10-11", and "MCS index 12-13" when the channel bandwidth is other than 20MHz.

[0052] In the EHT setting section 104, such as Figure 3 As shown in the enlarged view on the right, each item allows you to select one of the following: "1 spatial stream", "2 spatial streams", or "Not supported". Additionally, the initial value for each item is "1 spatial stream".

[0053] Thus, in the above embodiment, when the control unit 16 is performing a measurement of communication according to the IEEE 802.11be standard, it switches between the setting screen of capability element parameters and the setting screen of communication in SISO mode and the setting screen of communication in MIMO mode and displays them on the display unit 15.

[0054] Therefore, the setting screen for capability element parameters can be switched and displayed using both SISO and MIMO communication settings. This makes the parameter setting screen easy to view, allowing for easy retrieval of the parameter to be set, and also helps to prevent parameter setting errors.

[0055] Furthermore, the control unit 16 sets the initial values ​​of the settings displayed in the SISO mode communication setting screen and the MIMO mode communication setting screen to different values.

[0056] Therefore, different initial values ​​are displayed on the communication setup screens for SISO and MIMO modes. Thus, by viewing the initial values, it is possible to distinguish between the SISO and MIMO communication setup screens.

[0057] While embodiments of the present invention have been disclosed, it will be apparent to those skilled in the art that additional modifications can be made without departing from the scope of the invention. All such modifications and equivalents are included in this technical solution.
