Low-cost high-fidelity asset tracking in data center facilities
In one embodiment, an activation unit may render a passive radio frequency identification tag visible to a tracking infrastructure. A radio frequency identification reader may read at close range a passive radio frequency identification tag 304 attached to a server 302. A controller may create an active radio frequency signal for the server 302. A radio antenna may transmit the active radio frequency signal to a position infrastructure node 160.
