ActiveTag System Overview
ActiveTag System Components
The following diagram (Figure 1) shows a very basic ActiveTag
system. The system has the following components:
•
Activator
– transmits a wake-up signal, which includes its ID
number, to the Tag.
•
Transmit Antenna
– an application-specific antenna used to
broadcast the Activator’s wake-up signal over a defined coverage
area.
•
Tag
– receives the wake-up signal and broadcasts its location
and identification information to a Receiver. Tags can be carried
by individuals, placed on assets or equipment, or mounted in or
on vehicles.
•
Receiver
– receives the Tag’s broadcast and sends the data to
some intelligent device – a computer or a Wiegand control panel,
for instance.
• One or more of the following: a computer running an application
or an intelligent controller.
An ActiveTag system can be as simple as a single Activator,
Receiver, transmit antenna and control panel to authorize access
through a door, or it can be a network of Receivers, Activators and
other devices controlled by a computer.
