## Title
Limiting service availability when sensor device is non-operational due to noise floor change

## Abstract

Concepts and technologies are disclosed herein for limiting service availability when a sensor device is non-operational due to a noise floor change. According to one aspect of the concepts and technologies disclosed herein, a connected home system includes a controller device configured to monitor a plurality of sensor devices deployed within a premises, and a sensor device of the plurality of sensor devices. The sensor device can monitor radio frequency (“RF”) noise in a radio environment associated with the premises. The radio environment is associated with an RF noise floor. The sensor device can determine whether the radio frequency noise exceeds a noise threshold. In response to determining that the RF noise exceeds the noise threshold, the sensor device can cause the controller device to exclude the sensor device from being monitored by the controller device until the RF noise returns to below the noise threshold.

## Background
BACKGROUND
Connected homes, also known as smart homes, are homes equipped with technology that allows users to control and interact with various aspects of their home. Some aspects of the connected home include home security and automation. Home security systems can be self-monitored or professionally monitored remotely by a monitoring center. In the past, monitored security systems typically utilized landline connections to communicate with a monitoring center. In recent years, however, improvements in wireless technology to increase reliability and coverage have facilitated the deployment of wireless devices in the connected home to replace earlier landline connections, and this trend is likely to continue. Utilizing wireless technology for security systems eliminates the security vulnerability of a severed landline, but increases the system's vulnerability due to the increase in the radio frequency noise floor and resulting degradation of signal quality between sensor devices and the host controller.
SUMMARY
Concepts and technologies are disclosed herein for limiting service availability when a sensor device is non-operational due to a noise floor change. According to one aspect of the concepts and technologies disclosed herein, a connected home system includes a controller device configured to monitor a plurality of sensor devices deployed within a premises, and a sensor device of the plurality of sensor devices. The sensor device can monitor radio frequency (“RF”) noise in a radio environment associated with the premises. The radio environment is associated with an RF noise floor. The sensor device can determine whether the radio frequency noise exceeds a noise threshold. In response to determining that the RF noise exceeds the noise threshold, the sensor device can cause the controller device to exclude the sensor device from being monitored by the controller device until the RF noise returns to below the noise threshold.
In some embodiments, the sensor device can cause the controller device to exclude the sensor device from being monitored by the controller device until the RF noise returns to below the noise threshold by generating a message and sending the message to the controller device. The message can instruct the controller device to exclude the sensor device from being monitored by the controller device until the RF noise returns to below the noise threshold. The controller device can receive the message from the sensor device and can exclude the sensor device from being monitored as a two-way device. This is because the controller device will not receive an acknowledgment (ACK) message from the sensor device since the sensor device will not send an ACK message due to noise. When the sensor device determines that the RF noise has returned to below the noise threshold, the sensor device can cause the controller device to resume normal monitoring of the sensor device. The sensor device can cause the controller device to resume monitoring of the sensor device by generating a further message that instructs the controller device to resume monitoring and sending the further message to the controller device.
In some embodiments, the controller device can generate an alert directed to a monitoring center that provides, at least in part, a monitoring service for the connected home system. The alert can identify the sensor device as being temporarily offline. The controller device can send the alert to the monitoring center.
In some embodiments, the sensor device can establish the baseline RF noise floor for the radio environment. The sensor device can establish a further baseline RF noise floor for the radio environment. The baseline RF noise floor and the further baseline RF noise floor can be associated with different times of day.

DETAILED DESCRIPTION
The concepts and technologies disclosed herein are directed to limiting service availability when a sensor device is non-operational due to a noise floor change. The number of wireless devices and other customer equipment utilized by households worldwide keeps increasing. Utilizing wireless technology is a common approach for many security and connected home systems. The extensive use of wireless technology increases the radio frequency noise floor for at least a portion of the system. This can limit customer security and can make part of the premise practically unprotected. The affected area could be away from a main controller, and basically a controller jamming detection of the main controller will not be activated and most likely this sensor device will marked as an offline device.
The concepts and technologies disclosed herein can implement a robust noise detection threshold based upon a radio link assessment for sensor devices utilizing Neyman-Pearson criteria when a radio environment will be changed. The proposed algorithm can make a determination between intentional jamming (correlated jamming signal), which should be reported as an alarm event, and a change in noise floor (e.g., white Gaussian or other kind of noise). When the noise floor is above this threshold, the system can receive an alert and any sensor in the affected area can be excluded from monitoring until the noise is cleared. This will provide monitoring for the rest of the system and the noisy area is excluded until the noise signal returns to below the threshold. An alert message can be provided to the customer and/or a monitoring center.
Moreover, the concepts and technologies disclosed herein can add an enhancement for wireless security systems and other systems, such as connected home systems, when the radio environment is changed, especially in non-licensed radio bands. In particular, a determination can be made whether signal quality is above a statistical threshold for system availability following UL/CE standards.
It should be appreciated that the above-described subject matter may be implemented as a computer-controlled apparatus, a computer process, a computing system, or as an article of manufacture such as a computer-readable storage medium. These and various other features will be apparent from a reading of the remaining Detailed Description and a review of the associated drawings.

The interface 110 embodied as a wired interface can be or can include a proprietary wired interface or a standardized wired interface such as Ethernet, High Definition Media Interface (“HDMI”), Universal Serial Bus (“USB”), combinations thereof, and the like.
The controller device 108 is illustrated as being in communication with a wireless access network 112 via a wireless communications link 114.

The controller device 108 also is illustrated as being in communication with a wireline network 118 via a wireline communications link 120. The wireline communications link 120 can be provided as an optional, backup link for the wireless communications link 114. The wireline network 118 can be or can include one or more packet-switched networks. The wireline communications link 120 can be or can include any wireline cabling, some examples of which include coaxial cable and fiber optic cable.
The wireline network 118 is also shown as being in communication with a monitoring center 122, which, in turn, is in communication with one or more emergency services 124. The monitoring center 122 can monitor the controller device 108 for alarms based upon data provided to the controller device 108 by the sensor devices 106. In response to detecting an alarm, personnel associated with the monitoring center 122 can communicate with the emergency services 124 on behalf of one or more customers associated with the premises 102 to dispatch the police, fire, and/or emergency medical authorities to the premises 102. Additionally, the monitoring center 122 can provide a notification of the dispatch to the controller device 108 and/or to one or more other devices, such as a mobile telephone, to notify the customer(s) that emergency authorities have been dispatched to the premises 102. The notification can include a telephone call, a text message, an application notification, a combination thereof, and/or the like.
The monitoring center 122 also is in communication with a customer data center 126. The customer data center 126 can store one or more accounts 128 associated with customers of one or more connected home services provided within the premises 102 by the connected home system 104. The account(s) 128 can include personal information, such as name, service address, billing address, telephone number, e-mail address, service description, billing information, and any other information associated with customers of one or more connected home services.
The operating environment 100 also includes one or more RF devices 130. The RF devices 130 are illustrated as being external to the connected home system 104. The illustrated RF devices 130 are intended to encompass devices that emit RF noise 132 into a radio environment associated with the premises 102 and, in general, the RF devices 130 are not functioning directly as part of the connected home system 104. It should be understood, however, that the sensor devices 106 also emit RF noise and can contribute to overall RF noise (not illustrated) that exists in the radio environment associated with the premises 102. The RF devices 130 can include any device that includes one or more components that emits RF signals. Emission of RF signals by the RF devices 130 can be intentional, unintentional, or incidental.
The illustrated sensor device 106 contains a threshold module 134 that can be executed by one or more processing components (best shown in FIG. 3) to detect whether the RF noise 132 meets or exceeds a threshold value set for a noise threshold of the radio environment associated with the premises 102. The threshold value identifies a noise level above a baseline RF noise floor 136 of the radio environment associated with the premises 102. The threshold value can be set by an entity, some examples of which include a user of the connected home system 104 or a service provider of a connected home service that utilizes the connected home system 104. The baseline RF noise floor 136 is indicative of the radio environment of the premises 102, including RF energy emitted by all devices, including the sensor device(s) 106 and the controller device 108. In addition, the baseline RF noise floor 136 can include RF energy emitted by at least a portion of the RF devices 130—for example, one or more of the RF devices 130 that frequently operates within the premises 102. The frequency with which such RF devices operate within the premises 102 can be indicative of whether the RF energy emitted by these devices is considered to be part of the baseline RF noise floor 136, or alternatively, part of the RF noise 132. The RF noise 132 includes RF energy above the baseline RF noise floor 136.
It should be understood that the threshold module 134 can set the baseline RF noise floor 136 based upon all devices operating within the premises 102 at or around the time when the sensor device 106 is deployed within the premises 102. The threshold module 134 can adjust the baseline RF noise floor 136 to account for more or less persistent RF energy within the radio environment. What constitutes persistent RF energy can be, for example, based upon RF energy that exists within the premises 102 for a pre-defined period of time and/or a frequency with which the RF energy is present. If, for example, the mobile device is associated with a visitor to the premises 102, the RF energy emitted by the mobile device can be considered RF noise 132. If, over time, the same or similar RF energy emitted by the mobile device is present, that RF energy can be added to the baseline RF noise floor 136, thereby establishing a new noise floor for the radio environment of the premises 102. Similarly, if the mobile device leaves the premises 102 or is not detected for a specified amount of time or with a certain frequency (e.g., every day), then the RF energy associated therewith can be removed from the new baseline RF noise floor, thereby returning the baseline RF noise floor 136 to the original value.
If the threshold module 134 determines that the RF noise 132 exceeds the threshold value set for the noise threshold, then the threshold module 134 can generate a message 138 directed to the controller device 108. The message 138 can instruct the controller device 108 to temporarily exclude the sensor device 106 from being monitored because of high noise floor. When the RF noise 132 returns to below the threshold value set for the noise threshold, the sensor device 106 can generate a further message 140 directed to the controller device 108. The further message 140 can instruct the controller device 108 to resume monitoring the sensor device 106. The controller device 108, in some embodiments, can send an alert 142 to the monitoring center 122 to inform the monitoring center 122 that the sensor device 106 is currently unavailable. The controller device 108 can send the alert 142 additionally or alternatively to a customer associated therewith.
It should be understood that some implementations of the operating environment 100 include multiple premises 102, multiple connected home systems 104, multiple controller devices 108, multiple interfaces 110, multiple wireless access networks 112, multiple wireless communication links 114, multiple wireless core networks 116, multiple wireline networks 118, multiple wireline communications links 120, multiple monitoring centers 122, multiple customer data centers 126, multiple threshold modules 134, multiple messages 138, multiple further messages 140, multiple alerts 142, or some combination thereof. Thus, the illustrated embodiment should be understood as being illustrative, and should not be construed as being limiting in any way.

Thus, it should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system.

For purposes of illustrating and describing some of the concepts of the present disclosure, the methods disclosed herein are described as being performed, at least in part, by the connected home system 104, the sensor device(s) 106, and/or the controller device 108 via execution of one or more software modules. It should be understood that additional and/or alternative devices and/or network nodes can provide the functionality described herein via execution of one or more modules, applications, and/or other software. Thus, the illustrated embodiments are illustrative, and should not be viewed as being limiting in any way.
The method 400 will be described from the perspective of the sensor device 106 executing the threshold module 134. The method 400 begins and proceeds to operation 402, where the sensor device 106 is deployed within the premises 102. From operation 402, the method proceeds to operation 404, where the sensor device 106 establishes the baseline RF noise floor 136. In some embodiments, the sensor device 106 can monitor RF energy within the radio environment of the premises 102 over time to establish the baseline RF noise floor 136, which can include an average RF energy present in the premises 102. In some embodiments, the sensor device 106 can establish multiple baseline RF noise floors 136, each of which is utilized for a different time of day. For example, on weekdays from 9 AM to 5 PM the baseline RF noise floor 136 might be lower than from 5:01 PM to 8:59 AM to account for when users are at the premises 102 using their devices that emit RF energy.
From operation 404, the method 400 proceeds to operation 406, where the sensor device 106 establishes a value for a noise threshold. The noise threshold for a particular device can be established during the installation thereof, and can be updated over time using an adaptive algorithm, whereby the RF link between the sensor device 106 and the controller device 108 would be assessed over time (e.g., daily, weekly, or some other time interval). One non-limiting example for setup of a noise threshold value can be in accordance with USACE/NAVFAC/AFCEC/NASA UFGS-28 20 01.00 10 (October 2007) such that: a false alarm rate of no more than 1 false alarm per sensor per 30 days at a specified probability of detection for interior alarms; a false alarm rate of no more than 1 false alarm per sensor per 5 days at the specified probability of detection an environmental alarm during nominal conditions that shall not exceed 1 per day per sensor for exterior alarms; error and throughput rates of single portal performance rates obtained when processing individuals one at a time; a Type I error rate is an error where the system denies entry to an authorized, enrolled identifier or individual (the rate shall be less than 1 percent); and a Type II error rate is an error where the system grants entry to an unauthorized identifier or individual. The entry control Type II error rate shall be less than [0.1] [0.01] [0.001] percent.
From operation 406, the method 400 proceeds to operation 408, where the sensor device 106 monitors the RF noise 132 in the radio environment. From operation 408, the method 400 proceeds to operation 410 where the sensor device 106 determines whether the RF noise 132 monitored at operation 408 exceeds the noise threshold. If the sensor device 106 determines that the RF noise 132 exceeds the noise threshold, the method proceeds to operation 412, where the sensor device 106 generates the message 138 directed to the controller device 108 to instruct the controller device 108 to temporarily exclude the sensor device 106 from monitoring. From operation 412, the method 400 proceeds to operation 414, where the sensor device 106 sends the message 138 to the controller device 108.
From operation 414, the method 400 proceeds to operation 416, where the controller device 108 excludes the sensor device 106 from monitoring in accordance with the instructions received from the sensor device 106 via the message 138. From operation 416, the method 400 proceeds to operation 418, where the sensor device 106 monitors the RF noise 132 in the radio environment. From operation 418, the method proceeds to operation 420, where the sensor device 106 determines whether the RF noise 132 still exceeds the noise threshold. If the sensor device 106 determines that the RF noise 132 still exceeds the noise threshold, the method 400 returns to operation 418, where the sensor device 106 continues to monitor the RF noise 132 in the radio environment. If, however, the sensor device 106 determines that the RF noise 132 no longer exceeds the noise threshold, the method 400 proceeds to operation 422.
At operation 422, the sensor device 106 generates the further message 140 directed to the controller device 108 instructing the controller device 108 to resume monitoring the sensor device 106. From operation 422, the method 400 proceeds to operation 424, where the sensor device 106 sends the further message 140 to the controller device 108. From operation 424, the method 400 proceeds to operation 426, where the controller device 108 resumes monitoring of the sensor device 106. From operation 426, the method 400 proceeds to operation 428, where the method 400 ends.
Returning to operation 410, if the sensor device 106 determines that the RF noise 132 does not exceed the noise threshold, the method 400 returns to operation 408, where the sensor device 106 monitors the RF noise 132 in the radio environment. This loop continues until the RF noise 132 exceeds the noise threshold.
Turning now to FIG. 5, an example logical design 500 of the sensor device 106 and interactions with the RF devices 130 and the controller device 108 will be described, according to an illustrative embodiment. The logical design 500 includes the RF devices 130 that emit the RF noise 132 that can be sensed by the sensor device 106. More particularly, the logical design 500 details aspects of the sensor device 106 in performing various operations described herein above with reference to the method 400 introduced in FIG. 4.
The illustrated sensor device 106 receives one or more signals 501, which can include the signals associated with the RF noise 132, via an RF interface front-end 502, which, in turn, provides the signal(s) 501 from the controller device 108 and, potentially, other devices, such as one or more devices operating in non-licensed ISM bands to a receiver 504 with automatic gain control (“AGC”) provided by a gain control module 506. The receiver 504 passes the signal(s) 501 to an RF detector 508. The RF detector 508 determines a signal level 510 for each of the signals 501 and passes the signal level 510 to logic that determines whether the signal level 510 is above a signal reliability threshold (generally shown at 512). The signal reliability threshold is tied to signal detection and not noise detection. A given signal of the signals 501 shall be detected even in the presence of noise such that the signal-to-noise ratio is above the signal reliability threshold. The sensor device 106 is to process the signal(s) 501, at least in part, by utilizing gain control via a gain control module 506 to raise the signal strength of the signal(s) 501 so that the sensor device 106 can distinguish incoming signals (e.g., from the controller device 108) from noise created by other device(s) located in and around the premises 102, such as the RF devices 130. If, however, it is determined that the signal level 510 is below the signal reliability threshold, flow proceeds to stop gain control (generally shown at 516) by the gain control module 506, and then back to the receiver 504, where the loop can repeat as needed.
The reliability threshold can be setup during the installation of the sensor device 106 based on a call back algorithm. For example, the reliability threshold can be setup minimizing probability of false alarm according to UL 1023 (i.e., Neyman-Pearson criteria). The reliability threshold can be setup for white Gaussian noise, which is a pure example of noise generated by customer appliances and other electronic devices. Another example can be found in the threshold following USACE/NAVFAC/AFCEC/NASA UFGS-28 20 01.00 10 (October 2007) standards, as described above. As yet another example, EN 50131-2-7-1:2012 (Part 2-7-1: Intrusion detectors for glass breaking) can be utilized such that: Pass/Fail criteria are established so at least 16 out of 18 attempts shall be detected for each glass type; and no single detector shall miss more than one time.
As mentioned above, the illustrated sensor device 106 can receive, among the signals 501, the RF noise 132 from the RF devices 130, also via the RF interface front-end 502, which, in turn, provides the signals 501 to the receiver 504. The receiver 504 passes the signals 501 to the RF detector 508. The RF detector 508, in addition to determining the signal levels 510 of the signals 501 as explained above, determines, as shown at 518, whether the signals 501 generate the RF noise 132 above a noise threshold. If so, the sensor device 106 can generate the message 138, and can send the message 138 to the controller device 108 to take the appropriate action. If the noise threshold is not reached, however, the sensor device 106 can utilize the gain control module 506 to stop gain control (generally shown at 516) and pass the signals 501 back to the receiver 504. It should be understood that although the noise threshold detection and the signal reliability threshold aspects are described separately, these aspects can occur simultaneously as the sensor device 106 processes incoming signals. Accordingly, the logical design 500 shown in FIG. 5 is merely illustrative and should not be construed as limiting of the operation of the sensor device 106.
