The WLAN deployment eco-system and the quality requirements of applications impose different dynamic characteristics that probably impact the connectivity and the quality. The use cases and environments relevant to the capabilities of DBS are as follows:
When the deployment includes time-sensitive applications using Wi-Fi, such as voice and video calls, which need to maintain active registration and connectivity parameters with the backend servers.
When users are using time-sensitive applications, such as voice calls, moving across a building for a continuous duration while roaming.
When users are using applications that need to have good connection quality while moving within a building that does not have continuous Wi-Fi network coverage. The building layout, obstruction, and other use cases may impact the Wi-Fi network coverage.
When the infrastructure channel plan has many channels (such as more than 15 channels).
The higher the level of those characteristics is, the more critical DBS is.
