System Components

Transponder

The WTActive transponder is an ultra-light radio transmitter fitted with a replaceable battery. The device is comprised of a micro antenna and a powerful microchip. Once activated by the electromagnetic field generated by the antenna, the chip transmits an alpha numeric code to two receiver modules.

The chip is housed inside a rigid, waterproof plastic case which can be fastened to the athlete’s ankle by means of a Velcro strap or mounted on a bicycle using a specially-designed attachment or applied to the back of a bib using a small sealable envelope.

Controller Box

The WTActive box carries out the following main functions:

• Activates and controls the antenna through the activating unit integrated into the main control board.
• Detects the codes transmitted by the transponder and received through the 2 receiver modules.
• Associates the relative time to each transponder code.
• Records the transponder code and its time in long term memory and transmits them to a PC through an Ethernet connection.

Antennas

The activating antenna generates an electromagnetic field which activates the chip as soon as it enters into the field. The antenna loop consists of a standard electrical cable and connects to the Activator connector on board the WTActive box. The antenna can cover up to 12 mt / 40 ft in width. Antenna options include a wire loop and a rubber, non-slip mat.

Receiver Modules

The system is comprised of two receiver modules that are connected to the WTActive box by serial cables.

The receiver modules receive the signal transmitted by the transponders and send it to the receiver unit integrated into the WTActive main control board. For optimal installation, the two receiver modules should be installed at the two opposite sides of the activating antenna loop or mat.

System Overview

The WTActive system is based on a dual frequency concept: the transponder is activated by a low frequency electromagnetic field and then transmits its code at a different, higher frequency. The use of a battery-powered / active transponder, in combination with the dual frequency principle, allows for a high read height, a low collision rate between transponders, and high accuracy even at top speeds and densities. The WTActive box control board generates a sharp edge and stable electromagnetic field around the activating antenna. When a transponder crosses into the electromagnetic field, it is activated by a powerful sensor that responds immediately to the activating field. Once activated, the transponder transmits its code. The code transmitted by the transponder is detected by the two receiver modules, which send the data to the control board of the WTActive box. The data is then processed and stored in the WTActive control board. The processed data is sent to the operator’s laptop computer via the Ethernet link.
