What is a heatmap in wireless networking?

A tool for monitoring network speed

A graphical representation of wireless signal strength and coverage

A heatmap in wireless networking is indeed a graphical representation of wireless signal strength and coverage. This tool is crucial for network planning and optimization as it visually displays how well the wireless signal reaches different areas within a space. By using color gradients, heatmaps illustrate areas of strong and weak signals, enabling network administrators to identify coverage gaps, assess interference, and optimize the placement of access points for better network performance.

In contrast to monitoring network speed or security methods, a heatmap focuses specifically on signal strength and coverage, making it an essential element for ensuring reliable wireless connectivity in a given environment. Understanding this concept helps in effectively planning and maintaining wireless networks to provide adequate coverage for users.
