The AeroScout T4b Tag is a small, Wi-Fi Active RFID device that facilitates bi-directional connectivity with any standard Wi-Fi network infrastructure. The tag can be used to determine location and status of mobile assets and people, and its wireless messages are received and processed by standard Wi-Fi access points, keeping infrastructure costs low and installation simple. Bi-directional communication between the tag and the Wi-Fi network enables advanced application capabilities and drives significant business value for customers in manufacturing, logistics, healthcare and other industries. Some examples of this include:

• Workers in harsh industrial environments or patients in hospitals can request assistance and then be acknowledged by the tag buzzing or vibrating — informing them that help is on the way
• In manufacturing environments, line operators can push the tag’s call button to request parts replenishment and later receive the status progress of the request back from the network using the tag’s LED colors
• A tag connected to a host device that is receiving and transmitting telemetry data can request verification that all of the information has been received

Key Features

Beaconing and Bi-directional Communication

Similar to all AeroScout tags, the T4b Tag performs location calculations through a unique beaconing method that keeps network impact low and ensures scalability and long battery life. In addition, the T4b Tag features full bi-directional Wi-Fi connectivity and security, enabling it to send and receive information and acknowledgments from the network for a variety of advanced applications.

Acknowledgements

The T4b Tag is capable of requesting and receiving system acknowledgements for events such as call button messages or telemetry transmissions. Acknowledgements can trigger various configurable audio-visual indicators on the tag.

Audio-Visual Indications

The tag includes two multicolor LED's, a buzzer and a vibrating mechanism. These indicators can be activated from the network and set up to represent specific events and information.

Call Button

The T4b Tag includes two call buttons, adding the ability to define events according to button pushes. Multiple messages can be set up by using different patterns of button-pushes.

Motion Sensing

The tag contains an on-board motion sensor. The sensor can be configured to trigger alerts. It also enables different transmission intervals for a tag when it is stationary or in motion – which reduces unnecessary network traffic and conserves battery life.

Additional Model

Worker Safety Model

An additional model, the T4b Worker Safety Tag, offers functionality for injury-alerting applications. When a person with a tag is not in motion for a defined amount of time, the tag sends an alert. The tagged person is alerted by the tag’s buzzer and vibrating mechanism that an emergency notification has been sent and can cancel the alert by pushing a call button.
