## Abstract

Systems and methods of voice annunciation of signal strength, quality of service, and sensor status for wireless devices are provided. Some methods can include determining a signal strength or range of a radio, determining quality of service events and statistics for a wireless device, or determining a status of a sensor and then verbally annunciating information or instructions relating to the determined signal strength or range, the determined quality of service events and statistics, or the determined sensor status.

## Background
FIELD
The present invention relates generally to wireless devices. More particularly, the present invention relates to a system and method of voice annunciation of signal strength, quality of service, and sensor status for wireless devices.
BACKGROUND
Many wireless devices, including, for example, smoke detectors, carbon dioxide detectors, security devices, and other types of sensors, are known in the art. However, such devices have various limitations.
For example, many wireless devices include a radio with a limited range. The limited range can cause difficulty during installation of a wireless device, especially when the wireless device is installed in an area with marginal reception conditions. For example, when the wireless device is installed in a region with marginal reception conditions, a user may have to revisit the wireless device to remedy an installation issue, thereby incurring additional cost. Range finding techniques are known, but often rely on a blinking LED, beep, or other cryptic annunciation.
Some wireless devices can be networked together in various configurations, such as a hub and spoke or mesh configuration, using a variety network protocols. Network protocols have failure modes, such as packet collision, packet corruption, and the like. However, known wireless devices are limited to simple voice annunciation of such conditions. Indeed, when additional information is available, known systems and methods have only allowed users to access such information via a software application on a smart phone, a website, and the like. Such tools can be cumbersome to use during an installation process.
When the wireless device is installed in any region, sensors therein must often be maintained. However, when the user is inexperienced with wireless devices, sensors, and sensor failure modes, any visit by the user can take longer than necessary. Voice annunciation of maintenance events in wireless devices is known. However, information provided by known systems and methods has not been sufficient for assisting the user attending to the wireless device.
In view of the above limitations and others, there is a continuing, ongoing need for improved systems and methods of installing and maintaining wireless devices.

DETAILED DESCRIPTION
While this invention is susceptible of an embodiment in many different forms, there are shown in the drawings and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention. It is not intended to limit the invention to the specific illustrated embodiments.
Embodiments disclosed herein include systems and methods of voice annunciation of signal strength, quality of service, and sensor status for wireless devices. For example, some embodiments can provide a user with information for allowing the user to quickly, intuitively, and decisively determine the quality of service that a wireless device with an integral radio is able to receive and provide, determine and diagnose quality of service issues with the wireless device, and determine a status of a sensor in the wireless device and necessary actions to take in the event of a sensor maintenance event, all without relying on smart phone software applications, blinking LEDs, beeps, or other cryptic annunciations. Indeed, some systems and methods disclosed herein can provide voice annunciation of instructions and guidance to the user during the sensor maintenance event and other detected events and conditions.
In some embodiments, the wireless device can include a voice annunciation module that can execute one or more software applications that include, for example, a quality of service algorithm for detecting and tracking the signal strength of the wireless device's radio or for detecting and tracking quality of service events and statistics, such as dropped packets, interferences, network collisions, and the like.
The wireless device can be placed in an installation mode by actuating a push button or a test switch, providing a voice command, or the like. When in the installation mode, the wireless device can provide a range finding function that can operate intermittently or continuously to determine a range of the wireless device's radio and verbally annunciate information relating to the determined range, thereby allowing hands free operation for the user. For example, in some embodiments, systems and methods disclosed herein can provide real time guidance and instructions to the user regarding the range of the wireless device's radio, such as when the wireless device is almost out of range, verbally annunciating the phrase: “Low signal. Move device closer to central monitoring station.”
Additionally or alternatively, when in the installation mode, the wireless device can verbally annunciate information and instructions relating to the detected quality of service events and statistics. In some embodiments, the quality of service events and statistics can be cleared, either individually or as a group, via a further command received from the user, for example, by actuating a button or a switch, providing the voice command, or the like.
In some embodiments, the wireless device can include the voice annunciation module that can execute one or more software applications that include, for example, a sensor monitoring algorithm for detecting failure modes of device sensors. While the wireless device is being serviced, the user can provide input to the wireless device, for example, by actuating the button or the switch, providing the voice command, or the like, to solicit voice annunciation from the wireless device that includes details about the device sensors. The details about the device sensors that can be annunciated by system and methods disclosed herein include, but are not limited to remaining battery life, cleanliness of the sensor, remaining sensor life, and recommendations on actions to take when a sensor threshold level is reached.
In some embodiments, a service company can maintain a group of sensors and can download specific threshold levels to the wireless device. For example, a threshold level can be specific to a type of maintenance event. Additionally or alternatively, service requirements can be determined and set according to a location of the wireless device or an application of the wireless device. For example, the wireless device in a harsh environment can have a lower threshold level for maintenance than the wireless device is a mild environment.
