The three main components are the Flat Pack Transponder, Reader , Reader Antenna and RF modules. The Flat Pack Transponder is mounted on a vehicle’s windshield at a location visible to the Reader antenna. The directivity of the Reader antenna provides a defined capture zone. Up to 8 antennas can be serviced by a single Reader via the RF modules.

The RF modules are connected to the antennas by means of co-axial cables. Transponder installation instructions are provided in Attachment A. In operation, the Reader via a selected RF module sends out a 915 MHz data stream in the format described below to each antenna in turn thereby establishing an intermittent RF field in each lane of the roadway. When a vehicle equipped with a transponder enters the field the pulses activate the transponder and cause it to respond with a data transmission on a carrier frequency of 915 MHz. It should be noted that the transponder is only activated when a 20 microsecond “wake-up” pulse is received. It will not radiate energy at any other time. Transponder radiation will be obscured by the stronger Reader RF field. The Transponder Tx data is received by the antenna which passes it to the RF module for detection and then to the Reader for decoding. If the Reader determines that re-programming of the transponder is necessary, the Reader sends an additional pulse stream to the transponder for that purpose. When the above process is completed on a given lane , it is repeated in the next lane and so on until as many lanes as necessary up to the full 8 lanes have been scanned. The timing for this process which shows RF activity for one lane is depicted in Figure 2. During a typical passage of a vehicle through a lane the transponder is typically read and programmed twice to confirm accuracy of the data and its CRC.

The Transponder transmits and receives Manchester encoded data streams in the 915 MHZ frequency band. On-Off Keying modulation is used. There are five major electronic subsystems on the circuit board: 1. The “hook” Antenna which receives and transmits RF energy 2. The RF Transmitter has two sub-sections. An RF Oscillator that is turned on by the ASIC during the entire time the Transponder transmits. The modulator which converts the baseband Manchester encoded data delivered from the ASIC to the 915 MHz band using OOK (On-Off Keying) data stream. 3. The Receiver which demodulates the 915MHz band RF pulses received from the reader via the antenna. 4. The ASIC which provides: Rx, Tx data and control interfaces, Manchester encoding/decoding, CRC generation/detection. The control interfaces keep the transponder circuitry in low current (“idle mode”) until a trigger pulse of between 10 and 30 microseconds is detected. The ASIC transmits a Manchester encoded 256 frame at 500 kilobits per second when a valid trigger pulse is detected. The ASIC only stores the incoming bit stream if the CRC is correct. 5. The Battery which provides 3.60 volt power to operate the transponder. Page 6 2.

Block Diagram of the Transponder 4. Transmitter The transponder transmits the data stream to the reader after receiving the 20μsec trigger pulse from the reader (IAG protocol),. This generates an OOK modulated signal centered at 915 MHz. The RF output power from the transponder is between -7 to -2 dBm. 4.1 General Description The transmitter consists of an oscillator and modulator. The oscillator generates the CW signal at 915 MHz. The RF signal is modulated by the modulator stage which provides OOK modulation and amplification of the RF signal. The output of the modulator is connected to the antenna.
