These terms are only used to distinguish the same type of information from each other.

[0049] WiFi is mainly divided into 2.4GHz WiFi and 5GHz WiFi. Among them, 2.4GHz is the earliest WiFi band, and 5GHz is a newer WiFi band. Although 5GHz WiFi can provide faster speed and better performance than 2.4GHz WiFi, 2.4GHz WiFi is still irreplaceable in daily use. The reasons are as follows:

[0050] 1. The WiFi coverage of 2.4GHz band is wider: Compared with 5GHz band, the signal wavelength of 2.4GHz band is longer, and under the same power, it has better penetration ability and can transmit signals farther. This means that in the scenario of large-scale coverage, using 2.4GHz band can provide wider WiFi coverage.

[0051] 2. The WiFi signal in the 2.4GHz band is more stable: Compared with the 5GHz band, the 2.4GHz band has a stronger ability to penetrate obstacles (such as walls, furniture, etc.), which makes the 2.4GHz band more stable in environments where the signal needs to pass through obstacles, such as in large residences, offices or public places.

[0052] 3. WiFi in the 2.4GHz band has wider device compatibility: Since the 2.4GHz band is the frequency band adopted by the early WiFi standard, most terminal devices support WiFi in the 2.4GHz band, while fewer terminal devices support WiFi in the 5GHz band.

[0053] 4. WiFi in the 2.4GHz band consumes less power: Compared with the 5GHz band, WiFi in the 2.4GHz band consumes less power. Battery-powered terminal devices can save more power by using WiFi in the 2.4GHz band.

[0054] Since WiFi in the 2.4 GHz band has the above advantages, in daily use, terminal devices often use WiFi in the 2.4 GHz band for communication.

[0055] With the development of communication technology, various Bluetooth devices are widely used. Figure 1 As shown, when the user uses the laptop computer 11, the laptop computer 11 can be connected to Bluetooth devices such as a Bluetooth keyboard 12, a Bluetooth mouse 13, a Bluetooth pen 14, and a Bluetooth headset 15 through Bluetooth. Thus, the user can more conveniently edit documents and input data through the Bluetooth keyboard 12 and the Bluetooth mouse 13, take handwritten notes and draw pictures using the Bluetooth pen 14, and make voice calls and play audio using the Bluetooth headset 15. The terminal devices such as laptop computers and mobile phones also use the 2.4 GHz frequency band for communication with Bluetooth devices.

[0056] like Figure 2 In the spectrum diagram shown, the horizontal axis is frequency and the vertical axis is signal strength. Signal 21 in the diagram is a Bluetooth signal and signal 22 is a WiFi signal. Therefore, when a terminal device is connected to multiple Bluetooth devices at the same time and connected to WiFi in the 2.4GHz band, the Bluetooth signal and the WiFi signal will interfere with each other, resulting in a decrease in the quality of the Bluetooth signal and the WiFi signal.

[0057] Specifically, when using a Bluetooth headset, Bluetooth mouse, Bluetooth keyboard and Bluetooth pen at the same time, the throughput and latency of WiFi will be greatly affected. Similarly, when the terminal uses WiFi to download files, the use of the above Bluetooth devices will be greatly reduced. For example, the Bluetooth headset will freeze, and the latency of the Bluetooth pen, Bluetooth keyboard and Bluetooth mouse will be very high.

[0058] In view of this, the present disclosure provides a method for adjusting the coexistence of Bluetooth and WiFi, in which a terminal can flexibly adjust the connection interval between the terminal and the Bluetooth device according to the actual needs of the currently connected WiFi in the 2.4GHz frequency band. For example, when the terminal needs to use WiFi to download, the terminal can increase the connection interval between the terminal and the Bluetooth device and reduce the frequency of interaction with the Bluetooth device, thereby effectively solving the problem of mutual interference between Bluetooth signals and WiFi signals, resulting in reduced signal quality.

[0059] The following describes in detail the method for adjusting the coexistence of Bluetooth and WiFi in an embodiment of the present disclosure in conjunction with the accompanying drawings.

[0060] Figure 3 FIG. 1 is a flow chart of a method for adjusting the coexistence of Bluetooth and WiFi according to an exemplary embodiment of the present disclosure. Figure 3 As shown, the exemplary embodiment method may include the following steps:

[0061] In step 301, the channel performance parameters of the WiFi of the target frequency band to which the terminal is connected are obtained.

[0062] The target frequency band is the 2.4 GHz frequency band. When the terminal is connected to the WiFi of the 2.4 GHz frequency band, the WiFi of the 2.4 GHz frequency band uses a channel for communication, and the channel is the target channel. The channel performance parameter is used to characterize the channel pressure of the target channel.

[0063] Optionally, the channel performance parameter may include a throughput requirement of the WiFi and / or channel information of the target channel.

[0064] The throughput requirement of the WiFi is used to characterize the data transmission rate currently required by the terminal. In practical applications, the terminal can obtain the throughput requirement of the WiFi by calling a preset interface such as TrafficStats.getPackets(@NonNull String iface). It is easy to imagine that the greater the throughput requirement of the WiFi, the greater the channel pressure of the target channel.

[0065] The channel information is used to characterize the busyness of the target channel. In practical applications, the terminal can obtain the channel information through CCA (Clear Channel Assessment). Specifically, the terminal can determine the channel information by monitoring the electromagnetic energy level on the target channel. Exemplarily, the channel information can be represented by any numerical value in (0, 1), and the closer the numerical value is to 1, the busier the target channel is, and the closer it is to 0, the less busy the target channel is. In this example, the closer the numerical value is to 1, the busier the target channel is, indicating that the channel pressure of the target channel is greater.

[0066] In step 302, in response to determining that the channel performance parameter satisfies a preset parameter condition, a connection interval between the terminal and the Bluetooth device is adjusted.

[0067] The Bluetooth device may include a Bluetooth mouse, a Bluetooth keyboard, a Bluetooth pen, etc. The connection interval is used to represent the time interval for data interaction between the terminal and the Bluetooth device.

[0068] When a terminal is connected to a Bluetooth device via Bluetooth, the terminal will exchange data with the Bluetooth device at a preset connection interval. Moreover, the shorter the connection interval, the better the real-time performance of data transmission between the terminal and the Bluetooth device, but at the same time, it will cause greater channel pressure. The longer the connection interval, the worse the real-time performance of data transmission between the terminal and the Bluetooth device, but it can reduce channel pressure to a certain extent.

[0069] In this example, the terminal can adjust the connection interval between the terminal and the Bluetooth device in real time based on the channel performance parameter, that is, the channel pressure of the target channel. It should be noted that the terminal can adjust the connection interval between all Bluetooth devices at the same time, or can adjust the connection interval between some Bluetooth devices, which is not limited in this disclosure. There are two ways to adjust:

[0070] First way:

[0071] When determining that the channel performance parameter meets a preset first parameter condition, the terminal may increase the connection interval between the terminal and the Bluetooth device.

[0072] The first parameter condition is used to indicate that the target channel currently has channel pressure.

[0073] Optionally, when the channel performance parameter includes the throughput requirement of the WiFi, the first parameter condition may be that the throughput requirement of the WiFi is greater than or equal to a preset value, for example, greater than or equal to 100 kbps. In other words, when the terminal determines that the throughput requirement of the WiFi is greater than or equal to 100 kbps, it indicates that the terminal has a large throughput requirement for WiFi. At this time, the connection interval between the terminal and the Bluetooth device may be increased, thereby reducing the channel pressure caused by Bluetooth communication on the target channel.

[0074] Optionally, when the channel performance parameter includes the channel information of the target channel, the first parameter condition may be that the channel information of the target channel is greater than or equal to a preset value, for example, greater than or equal to 0.7. That is, when the terminal determines that the channel information of the target channel is greater than or equal to 0.7, it indicates that the target channel is currently busy. At this time, the connection interval between the terminal and the Bluetooth device may be increased, thereby reducing the channel pressure on the target channel caused by Bluetooth communication.

[0075] Optionally, the channel performance parameter may further include the throughput requirement of the WiFi and the channel information of the target channel. At this time, when the throughput requirement of the WiFi and the channel information of the target channel respectively meet the above parameter conditions, the connection interval between the terminal and the Bluetooth device may be increased. This avoids unnecessary reduction of Bluetooth performance and improves the user experience.

[0076] Second way:

[0077] When determining that the channel performance parameter meets a preset second parameter condition, the terminal may reduce the connection interval between the terminal and the Bluetooth device.

[0078] The second parameter condition is used to indicate that the channel pressure does not currently exist on the target channel.

[0079] Optionally, when the channel performance parameter includes the throughput requirement of the WiFi, the second parameter condition may be that the throughput requirement of the WiFi is less than or equal to a preset value, for example, less than or equal to 20 kbps. That is, when the terminal determines that the throughput requirement of the WiFi is less than or equal to 20 kbps, it indicates that the terminal has a small throughput requirement for WiFi. At this time, the connection interval between the terminal and the Bluetooth device may be reduced, thereby improving the real-time performance of data transmission.

[0080] Optionally, when the channel performance parameter includes the channel information of the target channel, the second parameter condition may be that the channel information of the target channel is less than a preset value, for example, less than 0.5. That is, when the terminal determines that the channel information of the target channel is less than 0.5, it indicates that the target channel is not currently busy. At this time, the connection interval between the terminal and the Bluetooth device can be reduced, thereby improving the real-time performance of data transmission and ensuring the user experience of the Bluetooth device.

[0081] Optionally, the channel performance parameters may further include the throughput requirement of the WiFi and the channel information of the target channel. At this time, when the throughput requirement of the WiFi and the channel information of the target channel respectively meet the above parameter conditions, the connection interval between the terminal and the Bluetooth device may be reduced. This avoids the situation where the performance pressure of the target channel is increased due to errors in the acquired channel performance parameters.

[0082] In an optional example, the terminal may determine the adjusted connection interval I' based on the following formula (1).

[0083] I'=I+(30-I)×ca (1)

[0084] Wherein, I is the initial connection interval, such as 7.5ms, 11.25ms, etc., which can be set by relevant staff based on actual conditions, and the present disclosure does not limit this. ca is the channel information obtained based on the aforementioned CCA method, which can be in the range of (0, 1).

[0085] At the same time, in order to ensure the user's experience of using the Bluetooth device, the improved connection interval needs to be less than or equal to the preset connection interval, for example, less than or equal to 30ms.

[0086] Combining the above formula (1), it can be known that the adjusted connection interval I' is proportional to the ca value. In other words, the larger the ca value, the larger the determined connection interval I', and the smaller the ca value, the smaller the determined connection interval I'. In other words, the busier the target channel, the larger the determined connection interval I', which can alleviate the channel pressure to a certain extent. The less busy the target channel, the smaller the determined connection interval I', which can improve the real-time performance of data transmission to a certain extent.

[0087] In the adjustment method for coexistence of Bluetooth and WiFi provided in the embodiment of the present disclosure, the terminal can flexibly adjust the connection interval between the terminal and the Bluetooth device according to the channel performance parameters of the WiFi in the currently connected target frequency band, thereby effectively solving the problem of mutual interference between Bluetooth signals and WiFi signals, resulting in reduced signal quality.

[0088] Figure 4 FIG. 1 is a flowchart of another method for adjusting the coexistence of Bluetooth and WiFi according to an exemplary embodiment of the present disclosure. In this embodiment, the same steps as those in the previous embodiment will be briefly described and will not be described in detail. For details, please refer to the relevant description of any of the previous embodiments. In this embodiment, the method for adjusting the coexistence of Bluetooth and WiFi when the Bluetooth device is a Bluetooth headset will be further introduced. Figure 4 As shown, the exemplary embodiment method may include the following steps:

[0089] In step 401, it is detected that the terminal is connected to WiFi of the target frequency band, and the number of Bluetooth devices that have established Bluetooth connections with the terminal reaches a preset number threshold.

[0090] The target frequency band is the 2.4 GHz frequency band. The preset number threshold can be 1 or 3, which can be set based on actual conditions, and the present disclosure does not limit this. In actual applications, the terminal can monitor android.bluetooth.*.profile.action.CONNECTION_STATE_CHANGED (* is the name of each Bluetooth protocol supported by the device, such as a2dp\hfp, etc.) to record the number of Bluetooth devices connected to the terminal.

[0091] In this example, the terminal may execute subsequent steps when it is detected that a WiFi connection with the 2.4 GHz frequency band has been established and the number of Bluetooth devices that have established Bluetooth connections with the terminal reaches the preset number threshold.

[0092] In step 402, the channel performance parameters of the WiFi of the target frequency band to which the terminal is connected are obtained.

[0093] The channel performance parameter is used to characterize the channel pressure of the target channel used by the WiFi.

[0094] Optionally, the channel performance parameter may include a throughput requirement of the WiFi and / or channel information of the target channel.

[0095] In step 403, in response to determining that the channel performance parameter satisfies a preset parameter condition, the connection interval between the terminal and the Bluetooth device and the Bluetooth audio sampling rate of the Bluetooth headset are adjusted.

[0096] The scheme for adjusting the connection interval can be referred to the introduction of the above-mentioned embodiment, which will not be described in detail here. This example focuses on the scheme for adjusting the Bluetooth audio sampling rate of the Bluetooth headset.

[0097] The Bluetooth audio sampling rate of a Bluetooth headset refers to the frequency of sampling the audio signal during audio transmission. Specifically, it indicates the number of audio samples collected per second. The Bluetooth audio sampling rate of a Bluetooth headset is usually expressed in units of "Hz" (Hertz), and common values ​​include 44.1kHz and 48kHz. For example, when the Bluetooth audio sampling rate of a Bluetooth headset is 44.1kHz, it means that the audio signal will be sampled 44,100 times per second.

[0098] A higher sampling rate can restore the original sound more accurately and provide higher audio quality, but it will also increase the amount of data transmission and bring more channel pressure to the target channel. A lower sampling rate can reduce the amount of data transmission and reduce the channel pressure on the target channel, but it will also reduce the audio quality.

[0099] In this example, the Bluetooth audio sampling rate of the Bluetooth headset can be adjusted in the following manner.

[0100] First way:

[0101] The terminal may reduce the Bluetooth audio sampling rate of the Bluetooth headset when determining that the channel performance parameter meets a preset third parameter condition.

[0102] The preset third parameter condition is used to indicate that the target channel currently has channel pressure.

[0103] The third parameter condition may be the same as or different from the first parameter condition, and may be set by relevant staff based on actual conditions, and the present disclosure does not limit this. For the convenience of description, the third parameter condition is taken as the same as the first parameter condition to introduce the subsequent embodiments.

[0104] Optionally, when the channel performance parameter includes the throughput requirement of the WiFi, the third parameter condition may be that the throughput requirement of the WiFi is greater than or equal to a preset value, for example, greater than or equal to 100 kbps. That is, when the terminal determines that the throughput requirement of the WiFi is greater than or equal to 100 kbps, it indicates that the terminal has a large throughput requirement for WiFi, and at this time, the Bluetooth audio sampling rate of the Bluetooth headset may be reduced, that is, the terminal may reduce the number of samples transmitted per second when transmitting audio data to the Bluetooth headset.

[0105] For example, the terminal can obtain the Bluetooth audio sampling rate supported by the Bluetooth headset in advance, and then adjust the Bluetooth audio sampling rate of the Bluetooth headset to any value lower than the Bluetooth audio sampling rate currently used by the Bluetooth headset based on the obtained Bluetooth audio sampling rate supported by the Bluetooth headset. This reduces the amount of data transmitted by Bluetooth to a certain extent, saves the Bluetooth bandwidth and energy consumption between the Bluetooth headset and the terminal, and reduces the channel pressure caused by Bluetooth transmission to the target channel.

[0106] Optionally, when the channel performance parameter includes the channel information of the target channel, the third parameter condition may be that the channel information of the target channel is greater than or equal to a preset value, for example, greater than or equal to 0.7. That is, when the terminal determines that the channel information of the target channel is greater than or equal to 0.7, it indicates that the target channel is currently busy. At this time, the Bluetooth audio sampling rate of the Bluetooth headset may be reduced, thereby reducing the channel pressure caused by Bluetooth transmission to the target channel. The method of reducing the Bluetooth audio sampling rate can be found in the description of the aforementioned embodiment, which will not be repeated here.

[0107] Optionally, the channel performance parameter may further include the throughput requirement of the WiFi and the channel information of the target channel. At this time, when the throughput requirement of the WiFi and the channel information of the target channel respectively meet the above parameter conditions, the Bluetooth audio sampling rate of the Bluetooth headset may be reduced. This avoids unnecessary reduction of Bluetooth performance and improves the user experience.

[0108] Second way:

[0109] The terminal may increase the Bluetooth audio sampling rate of the Bluetooth headset when determining that the channel performance parameter meets a preset fourth parameter condition.

[0110] The preset second parameter condition is used to indicate that the target channel currently does not have the channel pressure.

[0111] The fourth parameter condition may be the same as or different from the aforementioned second parameter condition, and the present disclosure does not limit this. For the convenience of description, the following embodiments are introduced by taking the fourth parameter condition being the same as the aforementioned second parameter condition as an example.

[0112] Optionally, when the channel performance parameter includes the throughput requirement of the WiFi, the fourth parameter condition may be that the throughput requirement of the WiFi is less than or equal to a preset value, for example, less than or equal to 20 kbps. In other words, when the terminal determines that the throughput requirement of the WiFi is less than or equal to 20 kbps, it indicates that the terminal has a small throughput requirement for WiFi. At this time, the Bluetooth audio sampling rate of the Bluetooth headset may be increased, that is, the terminal may increase the number of samples transmitted per second when transmitting audio data to the Bluetooth headset.

[0113] For example, the terminal can obtain the Bluetooth audio sampling rate supported by the Bluetooth headset in advance, and then adjust the Bluetooth audio sampling rate of the Bluetooth headset to any value higher than the Bluetooth audio sampling rate currently used by the Bluetooth headset based on the obtained Bluetooth audio sampling rate supported by the Bluetooth headset. This can more accurately restore the original sound, provide higher audio quality, and enhance the user experience of the Bluetooth headset.

[0114] Optionally, when the channel performance parameter includes the channel information of the target channel, the fourth parameter condition may be that the channel information of the target channel is less than a preset value, for example, less than 0.5. That is, when the terminal determines that the channel information of the target channel is less than 0.5, it indicates that the target channel is not currently busy. At this time, the Bluetooth audio sampling rate of the Bluetooth headset can be increased to improve the user experience of the Bluetooth headset.

[0115] Optionally, the channel performance parameters may further include the throughput requirement of the WiFi and the channel information of the target channel. In this case, when the throughput requirement of the WiFi and the channel information of the target channel respectively meet the above parameter conditions, the Bluetooth audio sampling rate of the Bluetooth headset may be increased, thereby avoiding the situation where the performance pressure of the target channel is increased due to errors in the acquired channel performance parameters.

[0116] In an optional example, when adjusting the Bluetooth audio sampling rate of the Bluetooth headset, it can also be performed based on the following steps:

[0117] A sampling rate set consisting of Bluetooth audio sampling rates supported by the Bluetooth headset is obtained, and then a target Bluetooth audio sampling rate is determined in the sampling rate set according to the channel performance parameter, and the Bluetooth audio sampling rate of the Bluetooth headset is adjusted to the target Bluetooth audio sampling rate.

[0118] Among them, the greater the channel pressure represented by the channel performance parameter, the lower the determined target Bluetooth audio sampling rate is; the smaller the channel pressure represented by the channel performance parameter, the higher the determined target Bluetooth audio sampling rate is.

[0119] For example, in actual applications, the terminal can obtain the sampling rate set consisting of the Bluetooth audio sampling rate CO[n] supported by the Bluetooth headset through getCodecsSelectableCapabilities() (n is the number of Bluetooth audio sampling rate levels actually supported by the Bluetooth headset). For example, the obtained sampling rates are arranged from small to large, and may include: CO[1, 2, 3, 4, 5] = [44.1kHz, 48kHz, 88.2kHz, 96kHz, 192kHz].

[0120] Then, the terminal can determine the target Bluetooth audio sampling rate CO[m] in the sampling rate set based on the acquired channel performance parameters, where m is an integer, which can specifically correspond to the above-mentioned [1, 2, 3, 4, 5]. Optionally, it can be determined based on the following formula (2):

[0121]

[0122] CA is channel information obtained based on the CCA method, and may be specifically in the range of (0, 1).

[0123] For example, if CA is 0.8, m = 1 / 0.8 = 1.25, which is closest to the integer 1, then CO[1] is used, which is 44.1kHz. If CA is 0.6, m = 1 / 0.6 = 1.6667, which is closest to 2, then CO[2] is used, which is 48kHz.

[0124] Finally, the terminal can adjust the Bluetooth audio sampling rate of the Bluetooth headset to CO[m] through setCodecConfigPreference(newCodec). Combined with the above formula (2), it can be seen that the adjusted Bluetooth audio sampling rate is inversely proportional to the ca value. In other words, the larger the determined ca value, the busier the target channel is, and the lower the adjusted Bluetooth audio sampling rate is, which can reduce the channel pressure. The smaller the determined ca value, the less busy the target channel is, and the higher the adjusted Bluetooth audio sampling rate is, which can more accurately restore the original sound, provide higher audio quality, and enhance the user experience of the Bluetooth headset.

[0125] In the adjustment method for the coexistence of Bluetooth and WiFi provided in the embodiment of the present disclosure, the terminal can flexibly adjust the Bluetooth audio sampling rate of the Bluetooth headset according to the channel performance parameters of the WiFi in the currently connected target frequency band, thereby effectively solving the problem of mutual interference between Bluetooth signals and WiFi signals, resulting in reduced signal quality.

[0126] It should be noted that although the above-mentioned embodiments separately introduce the terminal adjusting the connection interval between each Bluetooth device and the terminal adjusting the Bluetooth audio sampling rate of the Bluetooth headset, in actual applications, when the terminal is connected to multiple Bluetooth devices and the multiple Bluetooth devices include a Bluetooth headset, the terminal can adjust both the connection interval between each Bluetooth device and the Bluetooth audio sampling rate of the Bluetooth headset, and the present disclosure does not limit this.

[0127] Figure 5 FIG. 1 is a flow chart of another method for adjusting the coexistence of Bluetooth and WiFi according to an exemplary embodiment of the present disclosure. Figure 5 As shown, the exemplary embodiment method may include the following steps:

[0128] In step 501, it is detected that the terminal is connected to WiFi of the target frequency band, and the number of Bluetooth devices that have established Bluetooth connections with the terminal reaches a preset number threshold.

[0129] The target frequency band is the 2.4 GHz frequency band.

[0130] In step 502, the connection interval between the terminal and each Bluetooth device, the Bluetooth audio sampling rate of the Bluetooth headset, and the channel performance parameters of the WiFi in the target frequency band to which the terminal has been connected are obtained.

[0131] In step 503, in response to determining that the channel performance parameter satisfies a preset first parameter condition, and the connection interval between the terminal and each Bluetooth device is less than or equal to a first preset value, and the Bluetooth audio sampling rate of the Bluetooth headset is greater than or equal to a first preset frequency, the connection interval is increased and the Bluetooth audio sampling rate of the Bluetooth headset is reduced.

[0132] The preset first parameter condition is used to indicate that the target channel currently has channel pressure.

[0133] For example, when it is determined that the channel performance parameter meets the preset first parameter condition, and the connection interval between the terminal and the Bluetooth device is less than or equal to 15ms, and the Bluetooth audio sampling rate of the Bluetooth headset is greater than or equal to 88.2k, the connection interval can be increased and the Bluetooth audio sampling rate of the Bluetooth headset can be reduced.

[0134] In step 504, in response to determining that the channel performance parameter meets the preset second parameter condition, and the connection interval between the terminal and each Bluetooth device is greater than or equal to the second preset value, and the Bluetooth audio sampling rate of the Bluetooth headset is less than or equal to the second preset frequency, the connection interval is reduced and the Bluetooth audio sampling rate of the Bluetooth headset is increased.

[0135] The preset second parameter condition is used to indicate that the target channel currently does not have the channel pressure.

[0136] For example, when it is determined that the channel performance parameter meets the preset second parameter condition, and the connection interval between the terminal and each Bluetooth device is greater than or equal to 25ms, and the Bluetooth audio sampling rate of the Bluetooth headset is less than or equal to 48k, the connection interval can be reduced and the Bluetooth audio sampling rate of the Bluetooth headset can be increased.

[0137] The present disclosure does not limit the execution order of the above steps 403 and 404.

[0138] In the adjustment method for coexistence of Bluetooth and WiFi provided in the embodiment of the present disclosure, the terminal can flexibly adjust the connection interval between each Bluetooth device and the Bluetooth audio sampling rate of the Bluetooth headset according to the channel performance parameters of the WiFi of the currently connected target frequency band, the current connection interval between each Bluetooth device, and the Bluetooth audio sampling rate of the Bluetooth headset. This effectively solves the problem of mutual interference between Bluetooth signals and WiFi signals, resulting in reduced signal quality.
