Abstract

The present disclosure provides system and method for or creating heat maps to visualize network coverage across floor plans within buildings A floor plan database (110) is maintained for storing the details of areas designated for survey. Equipped with a boundary definition module (120), the system delineates specific zones within the floor plan. A walk test module captures precise measurement points and associated signal metrics, RSRP/RSSI, throughout the survey area. The canvas module (140) facilitates the generation of custom views and bitmap images, and manages drawing operations on the canvas. A signal strength calculation module (150) assesses the signal strength across various regions by computing and normalizing the average signal values. The heat map definition module (160) finalizes the creation of the heat map by arranging a colour gradient scheme to reflect signal intensity, thereby enabling an intuitive and analytical visualization of network distribution and strength.

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.
