Yes, you can locate clients (both connected as well as not-associated) on a floorplan by using SPoT. SPoT is a Ruckus solution that can be purchased as on-prem (virtual SPoT) or as a SPoT cloud (as a service). Depending on your use-cases beyond just locating clients on a floorplan, there are more functions that our eco-system partners provide (on top of SPoT locations) to meet your needs.
