Definition of Heat Maps:
A heat map is a graphical representation of data where individual values are represented by colors. In the context of wireless networking, a heat map shows the wireless signal strength in different areas of a building.
Purpose of a Heat Map:
Heat maps are used to illustrate the effectiveness of wireless networking coverage, identify dead zones, and optimize the placement of access points (APs) to ensure adequate coverage and performance.
Comparison with Other Options:
Logical Diagram: Represents the logical connections and relationships within the network.
Layer 3 Network Diagram: Focuses on the routing and IP addressing within the network.
Service-Level Agreement (SLA): A contract that specifies the expected service levels between a service provider and a customer.
Creation and Use:
Heat maps are created using specialized software or tools that measure wireless signal strength throughout the building. The data collected is then used to generate a visual map, guiding network administrators in optimizing wireless coverage.
