After the initialization phase, the tag sends location blink message periodically with given refresh interval. For time between position updates, the Tag goes into sleep modes. There are several sleep modes available suitable for different use-cases, please read more information here.   

The blink message is received by set of Anchors and it is forwarded to RTLS Studio via Ethernet of WiFi backhaul, where position is calculated. The blink message can be optionally equipped with sensor data. All the data is further disseminated trough the API.  First steps with Sewio Real Time Location System are described here.
