Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a method and system for monitoring antennas of CPE equipment (Customer premises equipment) based on LTE (Long Term Evolution, 3GPP long term evolution technology). Background Art

[0002] In the field of wireless communication technology, the antenna is one of the most important components. The performance of the antenna directly affects the communication quality and range of wireless communication equipment. In practical applications, the quality of the antenna is often affected by environmental factors, manufacturing process, material quality and other factors. Therefore, the detection and evaluation of the antenna is a key step to ensure the normal operation of wireless communication equipment.

[0003] In the existing technology, the performance of the antenna is usually judged by testing the strength of the received signal (i.e. RSSI, Received Signal Strength Indication). Specifically, one device is used as the matching machine and the other device is used as the test machine. The matching machine sends a signal to the test machine, and the test machine returns the signal strength value after receiving the signal. By comparing the strength of the sent signal and the strength of the received signal, it can be judged whether there is a problem with the antenna of the test machine.

[0004] However, the existing technology in this field has some problems: first, the existing antenna test method can only detect large-scale problems, and cannot detect some subtle problems, such as antenna phase distortion, standing wave ratio imbalance, etc.; second, this method requires precise coordination between the two devices. If there is a problem with either the matching machine or the test machine, it will affect the accuracy of the test results; finally, this method is often affected by environmental factors in actual operation, such as multipath effect, noise interference, etc., which will affect the accuracy of the test results. Therefore, the existing technology often cannot meet the needs in actual applications. Summary of the invention

[0005] The present invention aims to provide a CPE device antenna monitoring method and system based on LTE to solve the above technical problems, without the need for precise coordination between devices, reduce the dependence between devices, and improve the accuracy of monitoring results.

[0006] In order to solve the above technical problems, the present invention provides a CPE device antenna monitoring method based on LTE, which is applied to a CPE device to be tested, and includes the following steps:

[0007] Receiving an LTE forced reception instruction, and starting an LTE forced reception mode based on the LTE forced reception instruction;

[0008] Respond to the monitoring signal and obtain the antenna signal value; the monitoring signal is continuously sent by the CPE test equipment in response to the LTE strong transmission instruction and after the LTE strong transmission mode is turned on;

[0009] The antenna status is monitored based on the antenna signal value and the preset signal threshold.

[0010] In the above scheme, the CPE device under test is turned on to the LTE strong reception mode based on the LTE strong reception instruction, and the CPE matching device is turned on to the LTE strong transmission mode based on the LTE strong transmission instruction. The antenna status of the CPE device under test can be monitored by simply transmitting and receiving the monitoring signal between the CPE device under test and the CPE matching device. There is no need for precise coordination between the devices. Even if a problem occurs on one side, it will not affect the accuracy of the final antenna status monitoring, thereby reducing the dependence between devices and improving the accuracy of the monitoring results.

[0011] It should be noted that the above solution can accurately monitor various problems of the antenna of the CPE device under test, including phase distortion, standing wave ratio imbalance, etc., by using LTE strong transmission technology and LTE strong reception technology between the CPE test equipment and the CPE device under test. Specifically, the antenna signal can be obtained by sending a monitoring signal to the CPE device under test, and the strength and quality of the antenna signal can be analyzed to determine the quality of the antenna of the CPE device under test.

[0012] It should be noted that the above solution can reduce the impact of environmental factors to a certain extent by using LTE strong transmission technology and LTE strong reception technology between the CPE test equipment and the CPE device to be tested, thereby improving the accuracy of the antenna status monitoring results. Specifically, since LTE strong transmission technology and LTE strong reception technology have strong anti-interference capabilities, they can reduce the impact of environmental factors such as multipath effects and noise interference, thereby improving the accuracy of the antenna status monitoring results.

[0013] Further, in the monitoring of the antenna state based on the antenna signal value and the preset signal threshold, the preset process of the preset signal threshold includes:

[0014] Obtain a fixed distance from the CPE test device;

[0015] Respond to the test signal and obtain a data set of signals without antennas while maintaining a fixed distance and removing the antennas; the test signal is continuously sent by the CPE test equipment in response to the LTE test forced transmission instruction;

[0016] While maintaining a fixed distance and installing an antenna, respond to the test signal and obtain an antenna signal data set;

[0017] A signal threshold is preset based on a data set of signals without an antenna and a data set of signals with an antenna.

[0018] In the above scheme, by confirming the fixed distance between the CPE test equipment and the CPE device to be tested and confirming the preset signal threshold by calculation, the accuracy of the signal threshold setting can be guaranteed, signal interference between the CPE device to be tested and the CPE test equipment can be avoided, and the stability of signal transmission between the devices can be guaranteed.

[0019] Furthermore, the non-antenna signal data set includes a plurality of non-antenna signal data under the same test signal, and the antenna signal data set includes a plurality of antenna signal data under the same test signal; the signal threshold is preset based on the non-antenna signal data set and the antenna signal data set, and the specific calculation method is:

[0020]

[0021] Where: K represents the signal threshold; | x 无 | min Indicates the no-antenna signal data with the smallest absolute value in the no-antenna signal data set; | x 有 | max Indicates the antenna signal data set with the largest absolute value in the antenna signal data set.

[0022] The signal threshold determined by the above scheme can further ensure the rationality and accuracy of the antenna monitoring results.

[0023] Furthermore, before the signal threshold is preset based on the data set of signals without antenna and the data set of signals with antenna, the method further includes:

[0024] Based on the data set of signals without antenna and the data set of signals with antenna, the difference between signals with antenna and signals without antenna corresponding to the same test signal is calculated;

[0025] Determine whether the antenna signal difference is greater than a preset strength difference threshold.

[0026] Furthermore, before the signal threshold is preset based on the data set of signals without antenna and the data set of signals with antenna, the method further includes:

[0027] If the antenna signal difference is less than or equal to the preset strength difference threshold, the fixed distance from the CPE testing device is reacquired based on the adjusted position of the CPE testing device.

[0028] In the above scheme, in order to further improve the accuracy and significance of the final antenna monitoring results, it is necessary to ensure that the difference between the presence and absence of antenna signals is greater than the preset strength difference threshold; if the difference between the presence and absence of antenna signals is less than or equal to the preset strength difference threshold, it is necessary to adjust the position of the CPE testing device or the CPE device to be tested, thereby changing the fixed distance between the two devices, while avoiding signal interference between the CPE device to be tested and the CPE testing device, and ensuring the stability of signal transmission between the devices.

[0029] In the above scheme, after the antenna status monitoring of any CPE device under test is completed, the CPE test device can be kept in the LTE strong transmission mode. At this time, it is only necessary to replace the CPE device under test and turn on the LTE strong reception mode, so as to realize automatic monitoring of the replaced CPE device under test, which can effectively improve the efficiency and accuracy of antenna monitoring. Specifically, since the CPE test device will continuously send out monitoring signals when it maintains the LTE strong transmission mode, when the CPE device under test turns on the LTE strong reception mode, it can automatically receive the monitoring signal and perform corresponding actions, thereby realizing automatic monitoring of the antenna status monitoring results.

[0030] It should be noted that the antenna monitoring method is not only applicable to CPE equipment, but can also be extended to antenna detection of other wireless communication equipment, and has broad application prospects.

[0031] The present invention also proposes a CPE device antenna monitoring method based on LTE, which is applied to CPE test equipment and includes the following steps:

[0032] Receive an LTE forced transmission instruction, and start the LTE forced transmission mode based on the LTE forced transmission instruction to continuously send a monitoring signal, so that the CPE device under test responds to the monitoring signal and obtains the antenna signal value, thereby enabling the CPE device under test to monitor the antenna status based on the antenna signal value and a preset signal threshold.

[0033] The above method enables the CPE device under test to be in LTE strong receiving mode, and the CPE matching device to be in LTE strong transmitting mode, and then the antenna status of the CPE device under test can be monitored through simple cooperation of the CPE device under test and the CPE matching device in sending and receiving monitoring signals. There is no need for precise cooperation between devices, and even if a problem occurs on one side, it will not affect the accuracy of the final antenna status monitoring, thereby reducing the dependence between devices and improving the accuracy of the monitoring results.

[0034] The present invention also proposes an LTE-based CPE device antenna monitoring system, comprising a CPE device to be tested, a CPE testing device and a control terminal; wherein: the control terminal is used to send an LTE strong reception instruction to the CPE device to be tested, and to send an LTE strong transmission instruction to the CPE testing device; the CPE testing device is used to receive the LTE strong transmission instruction, and to start the LTE strong transmission mode based on the LTE strong transmission instruction to continuously send a monitoring signal; the CPE device to be tested is used to receive the LTE strong reception instruction, and to start the LTE strong reception mode based on the LTE strong reception instruction, and to respond to the monitoring signal and obtain the antenna signal value, so as to monitor the antenna status based on the antenna signal value and a preset signal threshold.

[0035] In the above scheme, the CPE device to be tested and the CPE matching device can be the same device, or a machine with LTE strong transmission and strong reception functions. It should be noted that the CPE device to be tested can be turned on in LTE strong transmission mode and the CPE matching device can be turned on in LTE strong reception mode, and then the antenna status of the CPE device to be tested can be determined by the antenna signal value received by the CPE matching device. This method is similar to the principle provided by the above scheme and no further description is required.

[0036] The above solution enables the CPE device under test to be in LTE strong receiving mode and the CPE matching device to be in LTE strong transmitting mode. Then, the antenna status of the CPE device under test can be monitored through simple cooperation of the CPE device under test and the CPE matching device in sending and receiving monitoring signals. There is no need for precise cooperation between devices. Even if a problem occurs on one side, it will not affect the accuracy of the final antenna status monitoring, thereby reducing the dependence between devices and improving the accuracy of the monitoring results.

[0037] Furthermore, the control terminal includes a threshold setting module; the threshold setting module is used to preset a signal threshold, specifically including: obtaining a fixed distance between the CPE device to be tested and the CPE matching device; while maintaining a fixed distance and removing the antenna, allowing the CPE device to be tested to respond to a test signal and obtain a data set of signals without an antenna; the test signal is continuously sent by the CPE matching device in response to an LTE test forced transmission instruction; while maintaining a fixed distance and installing an antenna, allowing the CPE device to be tested to respond to a test signal and obtain a data set of signals with an antenna; and presetting a signal threshold based on a data set of signals without an antenna and a data set of signals with an antenna.

[0038] Furthermore, the antenna signal data set includes a plurality of antenna signal data under the same test signal; in the threshold setting module, a signal threshold is preset based on the non-antenna signal data set and the antenna signal data set, and the specific calculation method is:

[0039]

[0040] Where: K represents the signal threshold; | x 无 | min Indicates the no-antenna signal data with the smallest absolute value in the no-antenna signal data set; | x 有 | max Indicates the antenna signal data set with the largest absolute value in the antenna signal data set.

[0041] Furthermore, in the threshold setting module, before the signal threshold is preset based on the data set of signal without antenna and the data set of signal with antenna, it also includes: calculating the difference of the presence or absence of antenna signal corresponding to the same test signal based on the data set of signal without antenna and the data set of signal with antenna; and determining whether the difference of the presence or absence of antenna signal is greater than the preset strength difference threshold.

[0042] During the implementation of the above system, no other instruments or equipment are required. Only the CPE device to be tested, the CPE matching equipment and the control terminal are required to cooperate. The control terminal can be a PC. The overall architecture of the system is simple and easy to build. It can effectively lower the technical threshold of antenna monitoring and improve the convenience of antenna monitoring.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1 This embodiment provides a CPE device antenna monitoring method based on LTE, which is applied to a CPE device to be tested, and includes the following steps:

[0048] S1: receiving an LTE forced reception instruction, and starting an LTE forced reception mode based on the LTE forced reception instruction;

[0049] S2: respond to the monitoring signal and obtain the antenna signal value; the monitoring signal is continuously sent by the CPE test equipment in response to the LTE forced transmission instruction and after the LTE forced transmission mode is turned on;

[0050] S3: Monitor the antenna status based on the antenna signal value and the preset signal threshold.

[0051] In this embodiment, the CPE device under test is turned on to the LTE strong reception mode based on the LTE strong reception instruction, and the CPE matching device is turned on to the LTE strong transmission mode based on the LTE strong transmission instruction. The antenna status of the CPE device under test can be monitored by simply coordinating the transmission and reception of monitoring signals between the CPE device under test and the CPE matching device. There is no need for precise coordination between the devices. Even if a problem occurs on one side, it will not affect the accuracy of the final antenna status monitoring, thereby reducing the dependence between devices and improving the accuracy of the monitoring results.

[0052] In the specific implementation process, by using LTE strong transmission technology and LTE strong reception technology between the CPE test equipment and the CPE device under test, various problems of the CPE device under test antenna can be accurately monitored, including phase distortion, standing wave ratio imbalance, etc. Specifically, the antenna signal can be obtained by sending a monitoring signal to the CPE device under test, and the strength and quality of the antenna signal can be analyzed to determine the quality of the CPE device under test antenna.

[0053] In one embodiment, an LTE antenna signal can be sent on the CPE test device, the signal frequency is 2600MHz, the power is 20dBm, and the modulation mode is OFDMA; the LTE antenna signal is received on the CPE device to be tested, and the strength and quality of the received signal are recorded. The strength of the received antenna signal can be measured by the received signal code power (RSRP), and the quality of the received antenna signal can be measured by the received signal quality (RSRQ); by analyzing the strength and quality of the received antenna signal, the quality of the antenna of the CPE device to be tested can be determined. Specifically, if the RSRP is less than -90dBm or the RSRQ is less than 0.9, it is considered that there is a problem with the antenna of the CPE device to be tested, and it needs to be repaired or replaced.

[0054] It should be noted that a single antenna can be tested multiple times to ensure the accuracy and reliability of the monitoring results.

[0055] In the specific implementation process, by using LTE strong transmission technology and LTE strong reception technology between the CPE test equipment and the CPE device to be tested, the influence of environmental factors can be reduced to a certain extent, thereby improving the accuracy of the antenna status monitoring results. Specifically, since LTE strong transmission technology and LTE strong reception technology have strong anti-interference capabilities, they can reduce the influence of environmental factors such as multipath effects and noise interference, thereby improving the accuracy of the antenna status monitoring results.

[0056] In one embodiment, in the monitoring of the antenna state based on the antenna signal value and the preset signal threshold, the preset process of the preset signal threshold includes:

[0057] Obtain a fixed distance from the CPE test device;

[0058] Respond to the test signal and obtain a data set of signals without antennas while maintaining a fixed distance and removing the antennas; the test signal is continuously sent by the CPE test equipment in response to the LTE test forced transmission instruction;

[0059] While maintaining a fixed distance and installing an antenna, respond to the test signal and obtain an antenna signal data set;

[0060] A signal threshold is preset based on a data set of signals without an antenna and a data set of signals with an antenna.

[0061] In this embodiment, by confirming the fixed distance between the CPE testing device and the CPE device to be tested and confirming the preset signal threshold by calculation, the accuracy of the signal threshold setting can be guaranteed, signal interference between the CPE device to be tested and the CPE testing device can be avoided, and the stability of signal transmission between the devices can be guaranteed.

[0062] In one embodiment, the no-antenna signal data set includes a plurality of no-antenna signal data under the same test signal, and the antenna signal data set includes a plurality of antenna signal data under the same test signal; the signal threshold is preset based on the no-antenna signal data set and the antenna signal data set, and the specific calculation method is:

[0063]

[0064] Where: K represents the signal threshold; | x 无 | min Indicates the no-antenna signal data with the smallest absolute value in the no-antenna signal data set; | x 有 | max Indicates the antenna signal data set with the largest absolute value in the antenna signal data set.

[0065] The signal threshold determined in this embodiment can further ensure the rationality and accuracy of the antenna monitoring result.

[0066] In one embodiment, before the signal threshold is preset based on the data set of signals without antenna and the data set of signals with antenna, the method further includes:

[0067] Based on the data set of signals without antenna and the data set of signals with antenna, the difference between signals with antenna and signals without antenna corresponding to the same test signal is calculated;

[0068] Determine whether the antenna signal difference is greater than a preset strength difference threshold.

[0069] In one embodiment, before the signal threshold is preset based on the data set of signals without antenna and the data set of signals with antenna, the method further includes:

[0070] If the antenna signal difference is less than or equal to the preset strength difference threshold, the fixed distance from the CPE testing device is reacquired based on the adjusted position of the CPE testing device.

[0071] In this embodiment, in order to further improve the accuracy and significance of the final antenna monitoring results, it is necessary to ensure that the difference between the presence or absence of antenna signals is greater than the preset strength difference threshold; if the difference between the presence or absence of antenna signals is less than or equal to the preset strength difference threshold, it is necessary to adjust the position of the CPE testing device or the CPE device to be tested, thereby changing the fixed distance between the two devices, thereby avoiding signal interference between the CPE device to be tested and the CPE testing device, while ensuring the stability of signal transmission between the devices.

[0072] In this embodiment, after the antenna status monitoring of any CPE device under test is completed, the CPE test device can be kept in the LTE strong transmission mode. At this time, it is only necessary to replace the CPE device under test and enable it to turn on the LTE strong reception mode, thereby realizing automatic monitoring of the replaced CPE device under test, which can effectively improve the efficiency and accuracy of antenna monitoring. Specifically, since the CPE test device will continuously send out monitoring signals when it maintains the LTE strong transmission mode, when the CPE device under test turns on the LTE strong reception mode, it can automatically receive the monitoring signal and perform corresponding actions, thereby realizing automatic monitoring of the antenna status monitoring results.

[0073] It should be noted that the antenna monitoring method is not only applicable to CPE equipment, but can also be extended to antenna detection of other wireless communication equipment, and has broad application prospects.

[0074] In one embodiment, a CPE device antenna monitoring method based on LTE is also proposed, which is applied to CPE configuration and testing equipment, and includes the following steps:

[0075] Receive an LTE forced transmission instruction, and start the LTE forced transmission mode based on the LTE forced transmission instruction to continuously send a monitoring signal, so that the CPE device under test responds to the monitoring signal and obtains the antenna signal value, thereby enabling the CPE device under test to monitor the antenna status based on the antenna signal value and a preset signal threshold.

[0076] In this embodiment, the CPE device under test is turned on in the LTE strong receiving mode, and the CPE matching device is turned on in the LTE strong transmitting mode. Then, the antenna status of the CPE device under test can be monitored through the simple transmission and reception cooperation of the monitoring signal between the CPE device under test and the CPE matching device. There is no need for precise coordination between the devices. Even if a problem occurs on one side, it will not affect the accuracy of the final antenna status monitoring, thereby reducing the dependence between the devices and improving the accuracy of the monitoring results.

[0077] See also Figure 2 In one embodiment, a CPE device antenna monitoring system based on LTE is also proposed, including a CPE device to be tested, a CPE testing device and a control terminal; wherein: the control terminal is used to send an LTE strong reception instruction to the CPE device to be tested, and to send an LTE strong transmission instruction to the CPE testing device; the CPE testing device is used to receive the LTE strong transmission instruction, and to start the LTE strong transmission mode based on the LTE strong transmission instruction to continuously send a monitoring signal; the CPE device to be tested is used to receive the LTE strong reception instruction, and to start the LTE strong reception mode based on the LTE strong reception instruction, and to respond to the monitoring signal and obtain the antenna signal value, so as to monitor the antenna status based on the antenna signal value and the preset signal threshold.

[0078] In this embodiment, the CPE device to be tested and the CPE matching device can be the same device, or a machine with LTE strong transmission and strong reception functions. It should be noted that the CPE device to be tested can be turned on in LTE strong transmission mode and the CPE matching device can be turned on in LTE strong reception mode, and then the antenna status of the CPE device to be tested can be determined by the antenna signal value received by the CPE matching device. This method is similar to the principle provided by the above solution and no further description is required.

[0079] In the specific implementation process of this embodiment, by turning on the CPE device to be tested as the LTE strong receiving mode, and turning on the CPE matching device as the LTE strong transmitting mode, the antenna status of the CPE device to be tested can be monitored through the simple transmission and reception coordination of the monitoring signal between the CPE device to be tested and the CPE matching device. There is no need for precise coordination between the devices. Even if a problem occurs on one side, it will not affect the accuracy of the final antenna status monitoring, thereby reducing the dependence between devices and improving the accuracy of the monitoring results.

[0080] In one embodiment, the control terminal includes a threshold setting module; the threshold setting module is used to preset a signal threshold, specifically including: obtaining a fixed distance between the CPE device to be tested and the CPE matching device; while maintaining a fixed distance and removing the antenna, causing the CPE device to be tested to respond to a test signal and obtain a data set of signals without an antenna; the test signal is continuously sent by the CPE matching device in response to an LTE test forced transmission instruction; while maintaining a fixed distance and installing an antenna, causing the CPE device to be tested to respond to a test signal and obtain a data set of signals with an antenna; and presetting a signal threshold based on a data set of signals without an antenna and a data set of signals with an antenna.

[0081] In one embodiment, the antenna signal data set includes a plurality of antenna signal data under the same test signal; in the threshold setting module, a signal threshold is preset based on the non-antenna signal data set and the antenna signal data set, and the specific calculation method is:

[0082]

[0083] Where: K represents the signal threshold; | x 无 | min Indicates the no-antenna signal data with the smallest absolute value in the no-antenna signal data set; | x 有 | max Indicates the antenna signal data set with the largest absolute value in the antenna signal data set.

[0084] In one embodiment, in the threshold setting module, before the signal threshold is preset based on the no-antenna signal data set and the antenna signal data set, it also includes: calculating the antenna signal difference corresponding to the same test signal based on the no-antenna signal data set and the antenna signal data set; and determining whether the antenna signal difference is greater than the preset strength difference threshold.

[0085] The system provided in this embodiment does not require the assistance of other instruments and equipment during implementation. It only requires the cooperation of the CPE device to be tested, the CPE matching device and the control terminal. The control terminal can be a PC. The overall system architecture is simple and easy to build, which can effectively lower the technical threshold of antenna monitoring and improve the convenience of antenna monitoring.

[0086] In order to more clearly illustrate the technical points of the present invention and highlight its technical effects, this embodiment provides a CPE device antenna monitoring system based on LTE, which is used to perform a CPE device antenna monitoring method based on LTE during the CPE device production process to monitor the quality of the antenna. For details, see Figure 3 As shown, including:

[0087] 1) The control terminal communicates with the CPE device to be tested and the CPE matching device. The control terminal can be an actual production tool, such as a PC, and socket communication can be used between the control terminal and the CPE device to be tested and the CPE matching device.

[0088] 2) By controlling the operation of the terminal, corresponding control instructions can be sent to the CPE device to be tested and the CPE matching device to enable the CPE device to be tested and the CPE matching device to perform strong antenna transmission / reception, such as controlling the CPE matching device to start the LTE strong transmission mode and controlling the CPE device to be tested to start the strong reception mode. Among them, the CPE device to be tested and the CPE matching device are both equipped with LTE modules. After the LTE module enters the FTM (Field Test Mode) mode, it can perform RF performance testing. After the CPE device to be tested enters the FTM mode, it only needs to set the transmission band, frequency and bandwidth to start the strong reception mode to continuously receive signals; after the CPE matching device enters the FTM mode, it only needs to set the transmission band, frequency and bandwidth to start the strong transmission mode to continuously transmit continuous waves.

[0089] It should be noted that the model of the LTE module may be LTE Cat4, which has a higher data transmission rate and lower latency, and can meet the needs of antenna monitoring.

[0090] 3) The antenna signal value returned in the strong receiving mode of the CPE device under test can be obtained by the control terminal and compared with the preset signal threshold to obtain the quality result of the antenna of the CPE device under test; if the antenna signal value is greater than the preset signal threshold, it means that the antenna is normal; if the antenna signal value is less than or equal to the preset signal threshold, it means that the antenna is abnormal.

[0091] This embodiment does not require the construction of a complex test environment. Only one testing device is needed to monitor the antenna. There is no need for precise coordination between devices. Even if a problem occurs on one side, it will not affect the accuracy of the final antenna status monitoring, thereby reducing the dependence between devices and improving the accuracy of the monitoring results.

[0092] It should be noted that in the actual production process, after the CPE test equipment enters the FTM mode and starts the strong transmission mode, it only needs to keep running. The first CPE device to be tested enters the FTM mode and starts the strong reception mode to obtain the antenna signal value, and then compares it with the preset signal threshold to obtain the quality result of the antenna of the CPE device to be tested. After the test, you only need to replace the second CPE device to be tested for antenna monitoring, and so on, the antenna monitoring operation of all CPE devices to be tested can be realized. The entire monitoring process is simple and convenient, which can effectively improve the efficiency of antenna monitoring and improve the actual production efficiency.

[0093] Furthermore, when two CPE devices perform strong transmission and reception of LTE, the signal value received by the strong reception device is affected by the placement and distance of the two devices. Therefore, it is necessary to fix the placement position, use the bad antenna device and the good antenna device to perform multiple tests, and finally find the preset signal threshold of the antenna. Specifically, the following technical solutions can be used:

[0094] 1) Place two CPE devices side by side facing each other with a distance of 70 cm;

[0095] 2) Under the above conditions, when the test antenna is normal, the antenna signal value obtained by the 4G antenna strong transmission and strong reception, the test results are shown in Table 1:

[0096] Table 1 Antenna signal value table obtained from the test with antenna

[0097] Antenna 1 Antenna 2 Antenna 3 Antenna 4 70cm Test 1 -183 -284 -294 -241 70 cm test 2 -191 -290 -284 -247 70cm Test 3 -189 -302 -299 -248 70cm Test 4 -182 -298 -303 -330 70cm Test 5 -183 -343 -299 -270

[0098] Antenna 1 to antenna 4 represent different antennas of a device, and a column of antenna signal values ​​obtained by testing the same antenna constitutes an antenna signal data set.

[0099] 3) Under the above conditions, remove antenna 1 to antenna 5 of the CPE device under test. When the test antenna is abnormal, the antenna signal value obtained by strong transmission and reception of the 4G antenna is shown in Table 2:

[0100] Table 2 Antenna signal value table obtained from the test without antenna

[0101] Antenna 1 Antenna 2 Antenna 3 Antenna 4 70cm Test 1 -353 -576 -581 -416 70 cm test 2 -364 -565 -543 -406 70cm Test 3 -345 -551 -523 -414 70cm Test 4 -351 -552 -507 -414 70cm Test 5 -348 -545 -509 -421

[0102] Among them, a column of antenna signal values ​​obtained by testing the same antenna constitutes a no-antenna signal data set.

[0103] 4) Calculate the signal thresholds that can be set for antenna 1-antenna 4 according to the preset signal threshold calculation method. Taking antenna 1 as an example, there are:

[0104]

[0105] Similarly, it can be obtained that the signal threshold corresponding to antenna 2 is -444, the signal threshold corresponding to antenna 3 is -405, and the signal threshold corresponding to antenna 4 is -368. The signal threshold determined in this embodiment can further ensure the rationality and accuracy of the antenna monitoring result.

[0106] The LTE-based CPE device antenna monitoring method provided in this embodiment can effectively improve the efficiency of antenna monitoring and improve actual production efficiency.
