Wireless Heat Map Analysis

Wireless Heat Map Analysis

Various user scenarios (e.g. different environments and user behaviors) can affect the performance of IoT devices significantly. Unlike traditional log-linear analysis, Heat Map Analysis can visualize the signal distribution in the customized environments, allowing you to consider real-world factors during the product validation process.

As more and more devices come on-line, the limited wireless channels have become more congested as well. The three issues below are often occurred when these signals (e.g. 4G, Wi-Fi, and Bluetooth®) coexist under the same roof, decreasing user satisfaction.

  • Connectivity Instability
  • Communication Latency
  • Poor Roaming Capability

 The Integrity of Wireless Signal 

Heat Map Analysis provides an immediate visual summary for various wireless signals (e.g. Wi-Fi, Bluetooth®, Zigbee), allowing you to perceive Received Signal Strength Indicator (RSSI) to validate the connectivity and performance of smart devices.

Testing in Real-World Scenarios

Since the communications of IoT devices have been extended to “one-to-many,” vendors need customized testing plans, which should include multiple situation models structured by various user scenarios (e.g. different environments and user behaviors), to help them identify root causes more accurately.
