As is shown in
The primary wireless device 102 includes a second communication unit 105 which facilitates communication between the primary wireless device 102 and the secondary wireless device 120 via a wireless link 124. The wireless link 124 is also referred to as an over-the-air (OTA) link. The second communication unit 105 includes an antenna coupled to an RF front-end, RF transceiver, and modem (see, e.g.,
During the installation process, the primary and secondary wireless devices 102, 120 are moved together as a movable apparatus 100 about the premises in an effort to find a location and position that provides for reliable reception of signals transmitted by the remote signal source 104. To provide power to the primary wireless device 102 during the installation process, a portable power source 108 can be temporarily connected to the primary wireless device 102 (e.g., via a bracket arrangement and a power cable). Use of the portable power source 108 allows the primary and secondary wireless devices 102, 120 to be freely moved about the premises without encumbrances of a power cord connected to the primary wireless device 102.
As the primary and secondary wireless devices 102, 120 are moved about the premises, the primary wireless device 102 receives signals from the remote signal source 104 and generates signal quality parameters. For example, the primary wireless device 102 can generate a Reference Signal Received Power (RSRP) parameter, a Reference Signal Received Quality (RSRQ) parameter, a Signal-to-Interference-plus-Noise Ratio (SINR) parameter or other metric of signal quality. The secondary wireless device 120 can communicate a request to the primary wireless device 102 via the wireless link 124 for the signal quality parameter(s). In response to the request, the primary wireless device 102 can pass the signal quality parameter(s) to the secondary wireless device 120.
In some embodiments, the secondary wireless device 120 can output signal quality information 126 in a form perceivable by a human installer (e.g., visual, auditory, tactile). The secondary wireless device 120 can include a display and the signal quality information 126 can be presented on the display in various forms (e.g., numbers, text, graphics). For example, a signal quality meter (see, e.g.,
In other embodiments, the primary and secondary wireless devices 102, 120 can be moved about the premises by a robot rather than a human installer. In such embodiments, the secondary wireless device 120 need not include a display, audio output device, or a haptic output device. The signal quality information 126 can be output from the secondary wireless device 120 in the form of a signal (e.g., digital data) suitable for use by the robot.
As is shown in
The primary wireless device 102a includes a first communication unit 105 which facilitates communication between the primary wireless device 102a and the remote signal source 104 via a wireless link 106. The first communication unit 105 includes an RF front-end, RF transceiver, modem, and the antenna 125 (see, e.g.,
As the primary wireless device 102a and the antenna 125 are moved about the premises, the primary wireless device 102a receives signals from the remote signal source 104 and generates signal quality parameters (e.g., RSRP, RSRQ, SINR). The secondary wireless device 120 can communicate a request to the primary wireless device 102 via the wireless link 124 for the signal quality parameter(s). In response to the request, the primary wireless device 102a can pass the signal quality parameter(s) to the secondary wireless device 120. The secondary wireless device 120 can output signal quality information 126 in a form perceivable by a human installer (e.g., visual, auditory, tactile) or in a form suitable for use by a robot, as previously discussed.
The installation process shown in
The installer initiates 500 the installation process which involves grasping the movable apparatus having one of the two configurations discussed above. The installer moves 502 the apparatus about a premises, such as by translating and rotating the apparatus. Translating the apparatus can involve changing the height and/or the lateral position of the apparatus. Rotating the apparatus can involve changing one or both of an azimuth angle and an elevation angle of the apparatus. While the apparatus is moved 502, a data acquisition process 504 is implemented. For the discrete or continuous movement of the apparatus in block 502, the secondary wireless device requests and receives signal quality parameters (e.g., RSRP, RSRQ, SINR) from the primary wireless device via an OTA messaging link established between the primary and secondary wireless devices.
In addition to signal quality parameters, other information can be acquired and recorded by at least one of the primary wireless device, the secondary wireless device, and the installer. Such additional information can include, for example, a timestamp, a GPS coordinate, a height of the primary wireless device, an azimuth angle of the primary wireless device, and an elevation angle of the primary wireless device. In a relatively simple implementation, the installer can perform the data acquisition 504, such as by recording (e.g., mentally or on paper) locations, heights, and orientations (azimuth and elevation angles) of the apparatus and the associated signal quality information. In a more complex example, the secondary wireless device (e.g., a smartphone) can provide a timestamp and include a GPS sensor and an inertial measurement unit (IMU), such as a gyroscope. The GPS sensor can provide the GPS coordinate and the IMU can provide the azimuth and elevation angles. The height data can be provided by the installer. These data and the associated signal quality information can be stored on the secondary wireless device.
A check is made at block 506 to determine if a data acquisition criterion has been met. In some approaches, the data acquisition criterion can be a target signal quality level (e.g., a target SINR). In other approaches, the data acquisition criterion can be a specified iteration value. In further approaches, multiple data acquisition criterion can be used, which can include a target signal quality level and a specified iteration value.
The specified iteration value can correspond to a specified number of times the processes of blocks 502 and 504 are to be implemented at one or more locations of the premises. For example, the installation process may require the installer to move to five different locations of the premises (e.g., five different rooms of a home when installing indoor wireless CPE) and, at each location, change the azimuth angle by turning the apparatus 360° in 10° increments while signal quality and other information are acquired at each increment. The specified iteration value in this example would be set at 180 (5*360/10). In another example, the installation process may require the installer to move to different locations of the premises and, at each location, change the azimuth angle and the elevation angle of the apparatus. For example, the apparatus can be moved to five different locations of the premises. At each location, the azimuth angle can be changed in 10° increments over 360° of movement, and the elevation angle can be changed in 10° increments over a range of 0-90° of movement while signal quality and other information are acquired at each increment. In this example, the specified iteration value would be set at 1800 (5*(360/10*90/10+1), noting that the “+1” accounts for an elevation of 0°).
The processes of blocks 502 and 504 are repeated until the data acquisition criterion has been met. The data acquired at block 504 and constraints of the physical environment at each of the locations of the premises are used by the installer to determine the optimal position to deploy the primary wireless device or external antenna. For example, the data acquired at block 504 can be reviewed (e.g., by the installer) or analyzed (e.g., by the secondary wireless device) to identify the location and apparatus orientations that produced the highest signal quality value. The installer can use the optimal parameters (e.g., GPS coordinate, height, azimuth and elevation angle) to deploy 508 the primary wireless device or external antenna at the optimal position at the premises. The installer terminates the installation process 510, which involves detaching the secondary wireless device from the primary wireless device or the external antenna.
The general installation process shown in
The fine positioning process seeks to optimally position the primary wireless device or antenna at a candidate location. For example, the gross locating process may identify the kitchen of a home as a candidate location for installing a primary wireless device (e.g., 5G CPE). In this example, the kitchen has a power outlet for supplying power to the primary wireless device and a mounting pole for supporting the primary wireless device. The fine positioning process can be used to optimally position the primary wireless device on the mounting pole.
Aspects of the fine positioning process will be described in the context of optimizing the azimuth angle of the primary wireless device at a candidate location, such as a kitchen. Due to physical constraints of the location where the mounting pole is situated in the kitchen, the azimuth angle of the primary wireless device in this example can be changed 502 in 10° increments over 180° of movement. The specified iteration value in this example is set at 19 (180/10+1). As the azimuth angle of the primary wireless device is changed by the installer, signal quality data is acquired 504 at 0° and each of the 10° increments, resulting in 19 sets of data (signal quality and associated azimuth angle data), at which point the data acquisition criterion 506 (specified iteration value of 19) is satisfied.
It may be determined by the installer or the secondary wireless device that azimuth angles of 30° and 110° produced the highest signal quality values. The fine positioning process seeks to determine whether an azimuth angle between 30° and 110° can produce a signal quality value higher than that associated with the azimuth angles of 30° and 110° (a span of 80°). In one example, the azimuth angle of the primary wireless device can be changed in 5° increments over 80° of movement between the azimuth angles of 30° and 110°. In this example, the specified iteration value is set at 16 (80/5). As the azimuth angle of the primary wireless device is changed 502 by the installer, signal quality data (signal quality and associated azimuth angle data) is acquired 504 at each of the 5° increments, resulting in 16 sets of data, at which point the data acquisition criterion 506 (specified iteration value of 16) is satisfied. It can be determined by the installer or the secondary wireless device that an azimuth angle of 90°, for example, produced the highest signal quality value. The azimuth angle of the primary wireless device can be set 508 at 90° by the installer. The fine positioning process can be similarly implemented for optimizing the elevation angle and height of the primary wireless device.
The primary wireless device 102 also includes a second communication unit 105, as is shown in
During an installation process, the apparatus 100 is moved about a premises in an effort to find a location and position for the primary wireless device 102 that provides for reliable reception of signals transmitted by the remote signal source 104. While moving the apparatus 100 about the premises, the primary wireless device 102 is in communication with the remote signal source 104 and generates signal quality parameters that change as the location and position/orientation of the primary wireless device 102 changes. The signal quality parameters are passed from the primary wireless device 102 to the secondary wireless device 120 via the OTA link 124 established between the second communication unit 105 and the communication unit 147. In some embodiments, the secondary wireless device 120 can include a display 121 which can display signal quality information that is viewable by the installer during the installation process. The apparatus 100 can be used to implement the processes shown
