[0025] Those skilled in the art will recognize that terms such as “above,” “below,” “upward,” “downward,” “top,” “bottom,” “left,” and “right” are used descriptively in the drawings and do not represent a limitation on the scope of this disclosure as defined by the appended claims. Furthermore, the teachings may be described herein in accordance with functional and / or logical block components and / or various processing steps.

[0026] The use of connected electronic devices, such as Internet of Things (IoT) devices, has become increasingly common. These devices have a variety of uses, including communicating with others, consuming media, or tracking objects, such as in a warehouse. Because of their ability to wirelessly connect to other devices, such as wireless hubs, they are often battery-powered. However, wireless communication can quickly deplete batteries. One feature of this disclosure is the improvement of battery life in connected devices while maintaining a high standard of operation that allows connected devices to function as intended.

[0027] Figure 1 A vehicle 10 incorporating a wireless mesh 38 is shown as a non-limiting example according to this disclosure. Figure 1 As shown, vehicle 10 includes a body 12 supported on wheels 16, wherein one or more of the wheels 16 are steerable. The body 12 partially defines a passenger compartment 18 having seats 20 located behind an instrument panel 22. Steering control 24 is arranged between the seats 20 and the instrument panel 22. Steering control 24 is operated to control the orientation of one or more of the steerable wheels 16.

[0028] Vehicle 10 includes an electric motor 26 connected to a transmission 28, which powers one or more of the wheels 16. A rechargeable energy storage system (RESS) 30 is disposed within the body 12 and supplies power to the electric motor 26. However, the positions of the electric motor 26, transmission 28, and RESS 30 relative to the body 12 can be different. Figure 1 The positions shown are different.

[0029] In the example shown, the wireless ecosystem 38 includes a hub 40 and multiple electronic devices 42, such as IoT devices, which communicate directly or indirectly with the hub 40 via wireless connections such as Bluetooth. In this disclosure, electronic devices 42 may include mobile devices, tablet computers, computers, monitoring devices, location trackers, etc.

[0030] Figure 2 This is a schematic diagram of a wireless ecosystem 38 according to a non-limiting example of the present disclosure. The wireless ecosystem 38 includes a wireless hub 40 configured to connect to or pair with a plurality of electronic devices 42 within the wireless ecosystem 38. The wireless hub 40 includes a housing 41, a user interface 48, and a wireless communication module 44 in electrical communication with a controller 46, such as an electronic control unit (ECU), for performing the method 100 described below.

[0031] In this disclosure, the controller 46 may be equipped with one or more processors (P), such as logic circuitry, combinational logic circuitry(s), application-specific integrated circuits (ASICs), electronic circuitry(s), central processing units(s), semiconductor IC devices, etc., as well as one or more input / output (I / O) circuitry, appropriate signal conditioning and buffering circuitry, and other components such as a high-speed clock. The ECU also includes associated non-transitory computer-readable storage media, i.e., memory (M), including read-only, programmable read-only, random access, hard disk drives, etc., whether resident, remote, or a combination of both.

[0032] Each electronic device 42 includes a wireless communication module that communicates directly or indirectly with the hub 40. A first set of electronic devices 42 is powered by a battery 43B, and a second set of electronic devices 42 is powered by a wired power supply 43W, such as a power outlet found in a residential or commercial building. As discussed in more detail below, this disclosure seeks to extend the operational life of these devices powered by the battery 43B by optimizing the wireless transmission power of the electronic devices 42.

[0033] Figure 3A method 100 is illustrated for operating a wireless ecosystem 38 to maximize the battery life of an electronic device 42 powered by a battery 43B. Method 100 begins at block 102 (“Connecting to a Hub”), where the electronic device 42 is connected to a wireless hub 40. In one example, the electronic device 42 connects to the wireless hub 40 via a pairing process such as a Bluetooth pairing process. The pairing process begins with the electronic device 42 being placed in discovery mode and the wireless hub 40 scanning for nearby Bluetooth devices in discovery mode. Once the wireless hub 40 identifies an available electronic device 42 for pairing, a user can select the desired electronic device 42, such as through a user interface 48 on the wireless hub 40. When the electronic device is paired with the wireless hub 40, operational parameters such as power (wired vs. wireless), device purpose, and the Bluetooth specification of the electronic device 42 are transmitted to the wireless hub 40. This information may be stored in the memory M of the wireless hub 40.

[0034] Furthermore, once the wireless hub 40 is paired with each electronic device 42, method 100 optimizes the wireless hub transmission power. This optimization is achieved by querying the electronic devices 42 with incrementally varying or decreasing wireless hub transmission power until a hub wireless transmission power level is reached where the wireless hub cannot communicate with one of the electronic devices 42. Method 100 can then select a previous wireless hub transmission power level that allows each electronic device 42 to communicate with the wireless hub 40. In one example, the incremental variation involves sequential queries utilizing a predetermined percentage reduction in transmission power, such as 50 percent. A feature of optimizing the wireless hub transmission power is reducing interference caused by transmitting wireless signals from the wireless hub 40 at distances greater than those required to communicate with each electronic device 42. With the electronic devices 42 paired and the hub transmission power optimized, method 100 proceeds to block 104.

[0035] At box 104 (“Assign Transmission Power”), the wireless hub 40 determines the wireless transmission power to be allocated to each electronic device 42 in the wireless ecosystem 38. The allocated wireless transmission power for each electronic device 42 is determined based on at least one of several different parameters, such as device type, whether the device is battery-powered or directly wired to a power source, or the device's location relative to the wireless hub 40. Furthermore, the allocated wireless transmission power may be determined based on battery capacity or the ease of battery replacement or charging. In one example, the wireless hub 40 may determine a fraction of the wireless transmission power to be allocated to the electronic device 42 by applying a value to each of the identified parameters or by utilizing a scaling factor.

[0036] like Figure 2As shown, the first set of electronic devices 42 includes a second set of electronic devices 42 with wired power 43W and battery power 43B. When the electronic devices 42 include wired power 43W, the allocated wireless transmission power can be maintained at the available elevated or maximum wireless transmission power because extending the battery life of the wired devices is not important. However, method 100 can still reduce the wireless transmission power of the wired devices to reduce transmission interference caused by making the wireless transmission power greater than the wireless transmission power required to communicate with the wireless hub 40.

[0037] When electronic device 42 is powered by battery 43B, method 100 attempts to reduce its wireless transmission power consumption to extend battery life. When method 100 allocates wireless transmission power to the battery-powered electronic device 42 43B, method 100 can utilize one of the electronic devices 42 with a wired power supply 43W to act as an intermediary in communication with the wireless hub 40. Figure 2 As indicated by the arrow, the battery-powered electronic device 42 43B can wirelessly communicate with one of the electronic devices 42 with a wired power supply 43W to reduce the transmission distance when powered by battery.

[0038] In this example, method 100 may allocate wireless transmission power to one of the battery-powered electronic devices 42, which is insufficient to reach the wireless hub 40 but can reach one of the adjacent electronic devices 42 with wired power 43W by forming a central wireless connection. The electronic device 42 with wired power 43W can then relay communications to the wireless hub 40. This allows the battery-powered electronic device 42 to operate for longer periods without the need for maintenance to replace or recharge the battery. With wireless transmission power allocated to each electronic device 42, the method may then proceed to block 106.

[0039] At block 106 (“Transmitting Transmitted Power”), method 100 utilizes the wireless hub 40 to transmit allocated wireless transmitted power to each electronic device 42. The electronic device 42 receiving the allocated wireless transmitted power can then modify the transmission power of its respective wireless transmission module to transmit at the allocated wireless transmitted power. With the electronic device 42 operating at the allocated wireless transmitted power, method 100 can then proceed to block 108.

[0040] At box 108 (“Connectivity verified?”), method 100 verifies that each electronic device 42 can communicate with the wireless hub 40 with the allocated wireless transmission power. As described above, a feature of this disclosure is that it allows the electronic device 42 to communicate with the wireless hub 40 either via a direct wireless connection or by utilizing another electronic device 42 to relay communications to the wireless hub 40.

[0041] In one example, each electronic device 42 transmits an acknowledgment message to the wireless hub 40 at an allocated wireless transmission power. If the wireless hub 40 does not receive an acknowledgment message from each electronic device 42, method 100 returns to block 104 and determines the modified wireless transmission power of one or more electronic devices 42 of the wireless hub 40 from which it has not received an acknowledgment message. Method 100 then proceeds to blocks 106 and 108 as described above to transmit the modified wireless transmission power and verify communication from each electronic device 42. Method 100 continues until the wireless hub 40 receives an acknowledgment message from each electronic device 42. When the wireless hub 40 verifies connectivity with each electronic device 42, method 100 proceeds to block 110.

[0042] At box 110 (“Collecting Performance Metrics”), method 100 collects performance metrics and device analysis from at least one of the electronic devices 42. For some electronic devices 42 that transmit infrequently, collecting and monitoring performance metrics may not be necessary, but for other devices such as those transmitting audio or video, collecting and monitoring performance metrics may be required. Once performance metrics are collected, method 100 proceeds to box 112.

[0043] At box 112 (“Are the performance metrics satisfactory?”), method 100 determines whether the collected performance metrics meet predetermined thresholds. By analyzing the performance metrics, method 100 can determine whether it needs to return to box 104 to dynamically adjust the wireless transmission power of the monitored electronic device 42. Specifically, monitoring the performance metrics of at least one of the electronic devices 42 and performing device analysis ensures that a given electronic device 42 meets predetermined performance metrics to ensure the desired communication quality occurs between the given electronic device 42 and the wireless hub 40.

[0044] Figure 4 An extended flowchart is shown for determining whether the performance metrics collected at box 110 are satisfied at box 112 by evaluating a set of rules and analyses of a given electronic device 42. In one example, the set of rules and analyses may include the usage history and power consumption analysis of the electronic device 42.

[0045] As shown in box 120 (“First operating state?”), method 100 determines whether electronic device 42 is operating in a first operating state based on information received from box 110. In one example, the first operating state includes electronic device 42 making a hands-free phone call. If electronic device 42 is operating in the first operating state, method 100 proceeds to box 122.

[0046] At box 122 (“Is the quality metric satisfied?”), method 100 determines whether the quality metric corresponding to the first operating state is satisfied. In one example, the quality metric in box 122 includes the Quality of Service (QOS) of a hands-free phone call made on electronic device 42. If the quality metric is at or above a predetermined threshold, such as a QOS of 4, method 100 proceeds to box 124.

[0047] At box 124 (“Is the quality metric satisfied?”), method 100 determines whether a second quality metric corresponding to the first operating state is satisfied. In one example, the quality metric in box 124 includes determining whether audio has been clipped or buffered. If the audio corresponding to the first operating state at box 120 has not been clipped or buffered, method 100 proceeds to box 126 (“No action”) and takes no action to change the operating parameters of the electronic device 42, such as transmission power or rule set. Method 100 then returns to box 110 to continue monitoring the performance metric.

[0048] If neither the quality metric from boxes 122 nor 124 is satisfied, method 100 returns to box 104 and determines whether dynamic adjustment of the wireless transmission power is required or whether the rule set of the wireless device 42 needs to be changed. The rule set may include information about how the transmission power of the electronic device 42 can be varied under certain operating conditions.

[0049] If the first operating state is not present at box 120, method 100 proceeds to box 128. At box 128 (“Second operating state?”), method 100 determines whether electronic device 42 is operating in a second operating state. In one example, the second operating state includes electronic device 42 streaming audio. If electronic device 42 is operating in the second operating state, method 100 proceeds to box 124. As described above, if the quality metric of box 124 is satisfied, method 100 proceeds to box 126 and takes no action. Method 100 then returns to box 110 to continue collecting performance metrics of the electronic device. If the quality metric of box 124 is not satisfied, method 100 returns to box 104 and determines whether dynamic adjustments to the wireless transmission power are needed or whether the rule set of wireless device 42 needs to be changed.

[0050] If neither the first nor second operating state exists for a given electronic device 42, method 100 proceeds to block 130. At block 130 (“Third operating state?”), method 100 determines whether electronic device 42 is operating in a third operating state. In one example, the third operating state includes electronic device 42 streaming video. If electronic device 42 is operating in the third operating state, method 100 proceeds to block 132.

[0051] At box 132 (“Is the quality metric satisfied?”), method 100 determines whether the quality metric corresponding to the third operating state is satisfied. In one example, the quality metric at box 132 includes determining whether the video has been clipped or buffered. If the video corresponding to the third operating state at box 130 has not been clipped or buffered, method 100 proceeds to box 126 and takes no action to change the operating parameters or rule set of the electronic device 42. If the quality metric at box 132 is not satisfied, method 100 returns to box 104 and determines whether dynamic adjustment of the wireless transmission power is needed or whether the rule set of the wireless device 42 needs to be changed. Method 100 may continue in this manner until the wireless hub 40 is deactivated or no more electronic devices are connected to it.
