Description

SYSTEM AND METHOD FOR IN-BUILDING HEAT MAP CREATIONS

FIELD OF DISCLOSURE

[0001] The present disclosure relates generally to a field of data visualization and analysis for indoor building networks. In particular, the present disclosure pertains to a system and a method for in-building heat map creations, which involves analyzing and visualizing data related to indoor building networks to improve their performance and efficiency.

BACKGROUND

[0002] In today's world, indoor buildings are becoming more complex, with multiple devices connected to indoor building networks. These networks are crucial for communication, security, automation, and other purposes, making them an integral part of indoor building infrastructure. However, managing these networks can be challenging, especially when it comes to visualizing and analyzing the distribution of the network across different areas of the building. There is often a lack of visibility into the network, making it difficult to identify areas that may be experiencing issues.

[0003] Existing tools for visualizing and analyzing indoor building networks are often limited in their capabilities. For example, some tools may only provide a basic overview of the network, while others may be too complex and difficult to use. Additionally, these tools may not be able to provide real-time data, which can be critical for identifying and resolving issues quickly.

[0004] One of the major problems with indoor building networks is that they are often designed and installed without considering the specific needs of the building. This can lead to issues such as poor network coverage, interference, and congestion. These issues can impact network performance, leading to slow data speeds and dropped connections.

[0005] Another challenge with indoor building networks is the increasing number of devices that are connected to them. As more devices are added to the network, the complexity of the network increases, making it more difficult to manage. This can lead to issues such as poor network performance, security vulnerabilities, and increased maintenance costs.

[0006] In addition, indoor building networks often have multiple access points, making it difficult to identify areas of the network that may be experiencing issues. This can lead to a lack of visibility into the network, making it difficult to identify and resolve problems quickly. Furthermore, network administrators may not have the tools needed to analyze the distribution of the network across different areas of the building, making it difficult to optimize network performance.

[0007] In conclusion, managing indoor building networks can be challenging due to the complexity of the networks and the lack of visibility into the network. Existing tools for visualizing and analyzing indoor building networks are often limited in their capabilities and may not provide real-time data.

[0008] There is, therefore, a need for a system and a method in-building heat map creations that can provide a comprehensive and real-time view of indoor building networks, making it easier to manage and optimize network performance.

[0056] Heat maps are useful tools for network planners and engineers to understand the strength and quality of wireless signals, such as cellular or Wi-Fi, within a building. By providing information on network coverage and identifying areas with poor signal strength or potential signal interference, heat maps can help optimize the overall network performance. Additionally, heat maps can be used to evaluate the quality of service provided to users in different areas of the building.

[0057] Existing heat map generating tools have limited capabilities and may not provide real-time data. These networks are often installed without considering the specific needs of the building, leading to problems such as poor coverage, interference, and congestion. To address these issues, it's important to consider the needs of the building before designing and installing the network. This will help ensure better coverage and performance.

[0058] The present disclosure discloses a system and method for generating heat maps to analyze wireless signal strength in indoor building networks. The system generates heat maps, which are graphical representations of data using color codes, on a floor plan to help network planners and engineers understand the quality and strength of wireless signals, like cellular or Wi-Fi, within the building. The heat maps can be used to visualize and analyze the distribution of a particular network across different areas of the building. This information can assist in optimizing network coverage, identifying areas with poor signal strength, and determining potential areas for signal interference.

[0059] Moreover, the present disclosure employs processing of the data obtained from the wireless signals, including the signal strength, signal-to-noise ratio, and other parameters related to wireless communication. The system may generate a report highlighting the areas with optimal signal strength and areas with poor signal coverage. This report can be used to identify critical areas in the building where additional access points or signal boosters may be required and to avoid potential signal interference.

[0060] Overall, the system may be configured to provide an efficient and effective way to analyze and optimize wireless signal coverage in indoor building networks. By generating heat maps and comprehensive reports, the system enables network planners and engineers to make informed decisions about optimizing network coverage and improving the quality of wireless signals within the building.

[0061] The present disclosure relates generally to data visualization and analysis for indoor building networks. In particular, the present disclosure pertains to a system and a method for in-building heat map creations. The invention generates a heat map on a floor plan for analyzing wireless signal strength, visualize and analyze the distribution of a particular network across different areas of the building. The heat maps are a widely used data visualization technique that can help network planners and engineers understand the strength and quality of wireless signals (such as cellular or Wi-Fi) within the building. This information can assist in optimizing network coverage, identifying areas with poor signal strength, and determining potential areas for signal interference.

[0062] The various embodiments throughout the disclosure will be explained in more detail with reference to FIGS. 1-9. [0063] FIG. 1 illustrates a system (100) having a network visualization tool designed to generate a heat map for visualizing network coverage within a building, based on a floor plan, in accordance with one embodiment. The system (100) integrates several modules, each performing distinct functions that collectively contribute to the heat map's generation, providing network engineers with a visual representation of signal strength distribution.

[0064] The system includes a memory (105), a receiving unit (102), and a processing unit (110). The processing unit (110) is configured as a command centre. The processing unit (110) is capable of executing a set of instructions that facilitate the interaction between the memory (102) and the other components of the system (100). The processing unit (110) is configured to handle complex computations and manage multiple tasks simultaneously, thereby ensuring efficient processing of the signal strength data and the subsequent generation of the heat map.

[0065] The memory (105) is configured to store a plurality of predefined floor plan templates. The receiving unit is configured to receive a user input from a user. The memory (105) serves as the data storage component of the system (100), wherein a floor plan database is housed. The floor plan database is dynamic, allowing for updating and retrieving of floor plan data as needed. The floor plan database contains digital representations of floor plans that may vary from simple single-room layouts to complex multi-level building schematics.

[0066] The processing unit is configured to cooperate with the receiving unit to receive the user input, and further configured to cooperate with the memory to retrieve the floor plan of an area to be surveyed from the memory based on the received user input.

[0067] The processing unit includes a boundary definition module, a measuring module, a canvas module, a signal strength calculation module, and a heat map definition module. [0068] The boundary definition module is configured to define one or more boundaries having a plurality of boundary points within the floor plan. In an example, the plurality of attributes includes reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference-plus- noise ratio (SINR), Received signal strength indicator (RSSI), Download throughput and Upload throughput. The boundary definition module (120) allows users to set parameters within the digital floor plan. The boundary definition module (120) can process various inputs to define specific zones, such as office spaces, hallways, or apartments, which are crucial for targeted signal strength analysis. The boundaries can be adjusted and redefined as per the requirements of the survey, making the system (100) versatile and adaptable to different building configurations.

[0069] The measuring module is configured to measure at least one attribute value associated with a plurality of attributes corresponding to each boundary point and is further configured to record the coordinates of each boundary point. In an embodiment, the plurality of attributes includes reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference-plus- noise ratio (SINR), Received signal strength indicator (RSSI), Download throughput and Upload throughput. To gather the data necessary for the heat map, the measuring module (130) incorporates a walk test module. The walk test module is configured to be interactive and intuitive. During the survey, it guides the user through the defined boundaries, ensuring that data is collected at all relevant points. The walk test module accurately records the geographic coordinates and the corresponding RSRP/RSSI values at each measurement point, which are pivotal for assessing the signal strength. In an embodiment, the walk test module is configured to measure at least one attribute value associated with the plurality of attributes by conducting a walk test survey within the defined boundaries. The walk test module utilizes the plurality of predefined floor plan templates to facilitate automated surveying and data collection. [0070] The canvas module (140) creates a custom view and bitmap for the floor plan, employing, for example, override option that is used to override and handle the intricacies of drawing on a canvas object. The canvas module is further configured to create and manipulate shapes representing one or more structural features within the building and to assign properties to the shapes to simulate physical barriers. The abstract data collected by the walk test module is translated into a visual format that can be easily interpreted. The canvas module (140) utilizes at least one drawing method to obtain and manipulate the canvas object, which is essentially a blank slate that serves as the foundation for the heat map's visual representation. The drawing algorithm (For example, the onDraw is an advanced algorithm that works to craft each pixel and shape that will eventually make up the final heat map. Through this process, the canvas object is transformed into a detailed and accurate visual representation of the data being analyzed.

[0071] In an aspect, the canvas module is further configured to:

• create a custom view and bitmap specifically designed for representing a floor plan. This means it generates a visual representation of a floor plan, likely for some kind of analysis or presentation purpose.

• may include an "override option" which allows the user/operator to customize or override default behaviour related to drawing on the canvas. This can be particularly useful for handling specific complexities or intricacies related to drawing operations.

• take abstract data collected by another module (the walk test module in this case) and translates it into a visual format. This process likely involves converting numerical or abstract data into graphical elements that can be easily understood and interpreted by users.

• employ the drawing algorithms for manipulating the canvas object within the onDraw method. This indicates that the module is not just performing simple drawing operations but is utilizing advanced techniques to generate the visual representation. These algorithms likely handle tasks such as data visualization, scaling, rendering, etc.

[0072] By manipulating the canvas object, the canvas module lays the groundwork for creating the heat map. In an example, the heat maps are graphical representations that use color to indicate the density of data points in a particular area. So, the canvas module is responsible for setting up the visual infrastructure necessary for generating heat maps based on the data provided. The signal strength calculation module (150) is responsible for the quantitative analysis of the signal data. The signal strength calculation module (150) divides the floor plan into predefined boundaries and then computes the average signal values for these regions. The process involves normalization of the measurement points' data to ensure that the signal strength is accurately represented across different areas. This module (150) is critical for ensuring that the heat map reflects true signal strength, thereby enabling effective network optimization. The signal strength calculation module is configured to calculate signal strength for each region defined by the boundaries by averaging the at least measured attribute value and aggregating normalized values of measurement points within each region.

[0073] The heat map definition module is configured to determine a heat map data by embedding at least one measured attribute value with each of the plurality of attributes and coordinates of each boundary point. The heat map definition module generates the heat map based on the determined heat map data. In an embodiment, the heat map definition module employs the colour gradient scheme that uses cooler colours for areas with higher signal intensity and warmer colours for areas with lower signal intensity. In an embodiment, the heat map definition module is further configured to overlay non-coverage areas in a grey colour to indicate regions without signal.

[0074] The heat map definition module (160) is configured for assigning colours to different signal strengths. Additionally, the heat map definition module (160) is configured creating a colour gradient scheme that intuitively represents the intensity of the signals. In an aspect, the heat map definition module (160) is configured to assign colors to different signal strengths. This means that based on the strength of the signal at a particular point on the floor plan, the module determines which color should represent that strength. Assigning colors in this way helps users quickly interpret the strength of signals across the area. In an aspect, the heat map definition module (160) is configured to employ a color gradient scheme that intuitively represents the intensity of the signals. A color gradient scheme typically involves smoothly transitioning colors from one end of the spectrum to another, indicating varying levels of intensity. This scheme helps users understand the relative strength of signals across different areas.

[0075] Further, the heat map definition module (160) is configured to employ a Color Determination algorithm that analyzes the signal strengths and determines the appropriate color for each intensity level. This determination is often based on a predefined threshold range, meaning that signal strengths falling within certain ranges are assigned specific colors. For example, if the signal strength is low (for example, between 1-10, then a grey color may be assigned accordingly. If the signal strength is high (for example, between 40-45, then a green code may be assigned. In an example, the predefined range and assignment of colors are configurable according to the operator or user.

[0076] The heat map definition module (160) iteratively processes each point on the floor plan. For each point, it calculates the signal strength and assigns the appropriate color based on the defined color gradient scheme. By doing this for every point on the floor plan, the module ensures that every area's signal strength is visualized on the heat map. By visualizing the signal strength for every area on the floor plan, the heat map definition module provides a detailed and accurate representation of network coverage. Users can easily identify areas with strong signals, weak signals, or areas with signal coverage issues, helping them make informed decisions about network optimization or deployment. [0077] The canvas module (140) is further equipped with features that enable the creation and manipulation of shapes representing structural features. The canvas module (140) is also configured to simulate the impact of physical barriers like concrete walls or glass partitions on signal propagation within the building.

[0078] In one implementation, the walk test module is enhanced with the capability to utilize predefined floor plan templates. The walk test module facilitates a more streamlined surveying process, allowing for automated data collection that reduces the potential for human error and speeds up the entire survey process.

[0079] In one implementation, the heat map definition module (160) incorporates an intelligent colour-coding scheme. The scheme is carefully designed to provide instant visual cues regarding signal quality, with cooler colours like blues and greens indicating stronger signals and warmer colours like yellows and reds indicating weaker signal strength. In some implementations, the heat map definition module (160) may mark and display areas having no-coverage in a distinct colour to denote absence of signal. For example, the heat map definition module (160) may show a grey colour to indicate lack of coverage or no-coverage.

[0080] FIG. 2 illustrates an exemplary floor plan (200), in accordance with an embodiment of the present disclosure. In an embodiment, the system (100) further comprises a heat map database for storing the heat map data, including the coordinates (x, y) and corresponding intensity values (e.g., RSRP or RSSI values) for each area or room in the floor plan.

[0081] In an embodiment, the colour gradient scheme within the heat map definition module (160) is based on a range of intensity values, and the colours are assigned based on the intensity values falling within the threshold range. The colour gradient scheme is a method used to represent different levels of intensity values on the heat map. The scheme works by assigning a range of intensity values to a specific colour that is then displayed on the heat map. The range of intensity values is divided into multiple thresholds, and each threshold is associated with a particular colour. For example, if it is considered the heat map that represents signal strength, the colour gradient scheme can assign a range of intensity values from 0 to 100 dBm to a specific colour, such as red. The range of intensity values is then divided into multiple thresholds, such as 0 to 20 dBm (170), 20 to 40 dBm (172), 40 to 60 dBm (174), 60 to 80 dBm (176), and 80 to 100 dBm (178). Each threshold is then associated with a specific shade of red, such as light red, medium red, and dark red. The colour gradient scheme makes it easier to visualize the intensity values on the heat map and identify areas of high or low intensity. By assigning different colours to different intensity values falling within the threshold range, the scheme provides a clear and concise representation of the data.

[0082] In an embodiment, the walk test survey is performed by the walk test module following a predefined path or coverage pattern. The walk test survey involves walking along the predefined path or coverage pattern while carrying a mobile device that is used to measure the signal strength and quality. In an example, the walk test survey may be performed by an operator. In some examples, the walk test survey may be performed using a robot. In some examples, the walk test survey may be determined based on floor plan, materials used in construction, and signal propagation understanding. The predefined path or coverage pattern is designed to cover all areas of the building or outdoor environment and ensure that the survey is comprehensive and accurate. The path may include all floors, rooms, and outdoor areas, and may follow the specific direction or pattern to ensure that all areas are covered. During the walk test survey, the mobile device measures the signal strength and quality at regular intervals, such as every few meters or at specific locations. The data collected is then used to generate a heat map that represents the wireless network coverage and performance in the building or outdoor environment.

[0083] In an embodiment, the signal strength calculation module (150) calculates the average RSRP/RSSI value for each region by aggregating the normalized values of the measurement points falling within each region. The signal strength calculation module (150) uses two parameters, RSRP (Reference Signal Received Power) and RSSI (Received Signal Strength Indicator), to measure the signal strength. The measurement points are collected during the walk test survey, where the signal strength is measured at regular intervals along the predefined path or coverage pattern. After the measurement points have been collected, the calculation module (150) divides the area into multiple regions and aggregates the normalized values of the measurement points falling within each region (180). The normalization process involves adjusting the measurement values to a standard scale to ensure that the values are comparable across different measurement points.

[0084] In an embodiment, the heat map definition module (160) creates a colour gradient scheme based on the intensity values and determines the colour for each intensity from the threshold range value (182). The heat map is generated using an algorithm for analyzing wireless signal strength in indoor building networks. This algorithm considers various factors such as signal absorption and reflection caused by building materials and layouts, ensuring a realistic representation of signal distribution within the floor plan.

This could involve adding metadata or tags to each shape in a digital model or using labels or symbols on a physical blueprint.

[0089] FIG. 4 illustrates an exemplary floor plan flowchart, in accordance with an embodiment of the present disclosure. The flowchart depicts systematic process employed by the system (100) which allows engineers to select the desired technology and subsequently create a comprehensive representation of a building’s floor plan with various structural and network components. [0090] At step (402), a user may be configured to send a request to the system (100), and the system (100) may be configured to initiate the steps to generate the heat map. The system (100) may facilitate the creation of the floor plan that serves as the foundation for generating a heat map. This heat map reflects various factors such as signal strength (RSRP), signal quality (RSSI), and overall network coverage, thereby enabling the optimization of wireless network distribution within the building or RSSI, measurement data needs to be collected and visualized on the map.

[0091] Upon initiating the process ('Start') (402), the user is prompted to select (404) the relevant technology ('Select Technology'), which bifurcates into two distinct paths: Wi-Fi (406) and 2G/3G/4G/5G/6G technologies, at (408). This selection is critical as it determines the subsequent options available to the user in the creation of the floor plan.

[0092] For the Wi-Fi technology path, the user is presented with options to define the structure (shapes) of the floor plan (410), including the ability to create outlines and define spaces using various shapes such as squares, circles, and freehand drawings. Openings such as doors and windows can be added, as well as labels for detailing and peripherals specific to Wi-Fi infrastructure. Additionally, Wi-Fi access points (AP) can be placed as components within the floor plan.

[0093] For the 2G/3G/4G/5G/6G and beyond technologies, at step (412), the user may be presented with several options to define the structure (shapes) of the floor plan. Conversely, when selecting 2G/3G/4G/5G/6G technologies, the user has access to similar structural (shapes) and opening options but with components tailored for cellular technologies, such as small cells. This path also includes a 'Prediction' feature, which allows for the forecasting of network coverage based on various parameters like transmitter and receiver distance, azimuth, standard deviation, path loss, and RSRP.

[0094] In both scenarios, the user can add predefined flats such as 1BHK, 2BHK, and 3BHK to the floor plan, providing a scalable and versatile approach to designing for different building types and sizes. Once the floor plan is completed with all desired elements, the process concludes ('End') (414).

[0095] In an operative aspect, the present disclosure discloses a method for creating the heat map of the floor plan in an indoor building for network planning, optimization and visualizing and analyzing the distribution of a network across different areas of the building. After selecting technology (e.g., Wi-fi or (2G, 3 G, 4G, 5G, 6G)), the user may be able to manually choose a floor plan template and drag-drop a plurality of structures into the chosen floor plan template. In an example, the plurality of structures may include openings, 3D peripherals, flats, Labels, and components. User may be able to create an outline with walls and add doors, windows, wall openings and corners. Further, the user may be able to set the size of any shape or wall by simply typing into its dimension label. In an aspect, the peripherals may have a plurality of display options to add peripherals. The 3D peripherals are available in all technology like Wi-Fi, LTE (Long-Term Evolution), NR (New Radio), etc. Using the predictions option, the system may be configured to predict network coverage based on transmitter and receiver distance, azimuth, standard deviation, path loss, and RSRP.

[0096] In an aspect, the user may choose various components like (Small Cell, Cabinet, Cable to connect, Wi-fi) along with the Floor Plan structure, which makes it easier for the engineers or users to visualize a real view of the floor plan Of Residential/Commercial building.

[0097] In an aspect, the system may be configured to allow the user to draw freehand drawings, making it easier to create any shape - like a hexagon or octagon - and visualize a plan more realistically.

[0098] The system (100) facilitates the creation of a floor plan that serves as the foundation for generating a heat map. This heat map reflects various factors such as signal strength (RSRP), signal quality (RSSI), and overall network coverage, thereby enabling the optimization of wireless network distribution within the building or RSSI, measurement data needs to be collected and visualized on the map.

[0099] FIG. 5 illustrates an exemplary created floor plan (500), in accordance with an embodiment of the present disclosure. In an embodiment, in the boundary definition module, the generating the heat map on the floor plan for analyzing wireless signal strength is to obtain the floor plan of the area that needs to be surveyed. This can be done by obtaining a blueprint or a digital representation of the floor plan on canvas. This floor plan will serve as the basis for the heat map. The next step is to define the boundaries within the floor plan. These boundaries could represent rooms, flats, or specific areas where you want to analyze the wireless signal strength. Defining the boundaries is important because it allows you to focus on specific areas of the floor plan and identify areas where the wireless signal strength may be weaker. Once the boundaries have been defined, the next step is to capture the boundary points to do the walk test and create the heat map inside it or region of interest. This involves performing the walk test survey within the boundaries, recording the coordinates of each measurement point, and capturing the corresponding RSRP/RSSI values at each measurement point. By capturing the boundary points, one can create the heat map that provides the visual representation of the wireless signal strength within the defined boundaries.

[00100] FIG. 6 illustrates an exemplary walk test (600) on the created floor plan, in accordance with an embodiment of the present disclosure. In an embodiment, performing the walk test survey within the area is an important step in generating the heat map on the floor plan for analyzing wireless signal strength. This survey involves physically walking through the area to be surveyed, following the predefined path or coverage pattern. The path or pattern is usually designed to cover the entire area and ensure that all parts of the area are surveyed. During the walk test survey, the coordinates (x, y) of each measurement point are recorded. These coordinates represent the location where the wireless signal strength is measured. The measurement points are usually spaced out at regular intervals along the path or pattern to ensure that the entire area is covered and that there is sufficient data to generate an accurate heat map. At each measurement point, the corresponding RSRP/RSSI values are captured. These values indicate the signal strength at each location. RSRP (Reference Signal Received Power) and RSSI (Received Signal Strength Indicator) are two commonly used metrics for measuring wireless signal strength. The RSRP/RSSI values are used to determine the strength of the wireless signal at each measurement point and are later aggregated to calculate the average signal strength for each region or room within the floor plan.

[00101] Creating a custom view and bitmap is an important step in generating the heat map on the floor plan for analyzing wireless signal strength. A custom view and bitmap allow you to create the visual representation of the heat map on the canvas. To create the custom view and bitmap, for example, onDraw method to handle drawing on the canvas may be overridden. The onDraw method is a built-in method in Android that is responsible for drawing the view's content on the canvas. By overriding this method, it is possible to customize how the view is drawn on the canvas. Once the onDraw method is overridden, the canvas object in the onDraw method is obtained using the following code:

[00102] canvas = getHolder().lockCanvas(); (1)

[00103] This code obtains the canvas object and locks it for editing. The canvas object is used to draw the heat map on the bitmap. Next, the bitmap object is needed to create using the following code:

[00104] Bitmap. Config conf = Bitmap.Config.ARGB_8888; (2)

[00105] bitmap=Bitmap .createB itmap(getW idth() ,getHeight() ,conf) ; (3 )

[00106] This code creates the bitmap object with the specified configuration and dimensions. The bitmap object is used to store the heat map data and is later drawn on the canvas.

[00107] FIG. 7 illustrates an exemplary divided canvas (700) for determining signal strength, in accordance with an embodiment of the present disclosure. To divide the floor plan into predefined boundaries, there is a need to use the boundary points captured during the walk test survey. These boundary points represent the corners of each predefined boundary and are used to define the boundaries for each region or room within the floor plan. Once defined the boundaries are obtained, the average RSRP/RSSI value for each region is calculated. This is done by aggregating the normalized values of the measurement points falling within each region. The normalized values are usually calculated by subtracting the minimum RSRP/RSSI value from the measured value and dividing the result by the range of values. This normalization process ensures that the RSRP/RSSI values are standardized and can be compared across different regions. After normalizing the RSRP/RSSI values, the values for each region and calculate the average RSRP/RSSI value for the region are aggregated. This average value represents the overall signal strength for the region and is used to determine the colour and intensity of the heat map for that region.

[00108] FIG. 8 illustrates an exemplary generated heat map (800), in accordance with an embodiment of the present disclosure. To prepare the heat map data, the coordinates (x,y) and corresponding intensity values (e.g., RSRP or RSSI values) for each area or room in the floor plan is included. This data is used to determine the colour and intensity of the heat map for each region. Next, a colour gradient scheme based on the intensity values is created. This scheme is used to determine the colour of each region based on its intensity value. For example, a gradient blue cab be used for high intensity, green for fair, yellow for good and red for low intensities. After creating the colour scheme, the colour for each intensity from the threshold range value is determined. This is done by mapping the intensity value to the corresponding colour in the gradient scheme. Once the colour scheme is determined, each point in the floor plan is iterated over. For each point, the position (x, y) of the point on the canvas is determined and calculated the radius of the circle based on the intensity value. The coordinates (x, y), radius, and intensity as circles can also be stored. Next, the heat map circles on the canvas by setting the colour of the circle using the getColour() function and the radius of the circle is drawn. Each heat map circle is iterated over, retrieved the colour associated with the intensity value for the current circle, and used the canvas' drawCircle method to draw a circle at the coordinates (x, y) of the current circle. Finally, the generated heat map is exported on the canvas or as an image. The heat map is generated using following codes: bigB inSize = 5f x = x + bigBinSize; - (4) kpiValue = (kpiValue + (rssi/rsrp)) / 2; - (5) bitmap. setPixel((x, y, getColour(kpiValue)); - (6) x = initialX; - (7) and y = y + bigBinSize; (next interval) - (8)

After next interval same above process will follow.

[00109] In an exemplary embodiment, a computer system in which or with which embodiments of the present invention can be utilized is disclosed.
