4 P R E LI M IN A R Y Lane Tuning Guidelines
A M IN LI E R P Y R
Chapter 4 Lane Tuning Guidelines R Why You Need to Tune a Lane Y This chapter explains the importance of lane tuning for optimum automatic vehicle identification (AVI) system performance and describes the MPI 6000 functions and features that can assist you in tuning an AVI lane.
MPI 6000 Multi-Protocol Reader System Guide Maximum traffic speed in the lane, which is used to determine the required length of the capture zone; also known as the footprint • The type of lane, that is, express or mixed-use lane • The presence of vehicle framing devices such as light curtains, which may dictate the desired location of the first read point • The presence of alternate toll collection devices, such as coin machines in mixeduse lanes, which may dictate the desired first read point • T
Lane Tuning Guidelines M IN A R Y To Be Provided. Figure 4-1 Field Size, Shape, and Antenna Polarization Define the Reading Range LI One concern for lane tuning is how large the footprint needs to be for acceptable system reliability. A rule of thumb frequently applied to this problem is that there should be time for a minimum of four complete transactions as the vehicle passes through the capture zone. Thus, the system that has the more complex transaction requires the larger footprint.
MPI 6000 Multi-Protocol Reader System Guide 3 reads @ 4 milliseconds each = 12 milliseconds 3 writes @ 4 milliseconds each = 12 milliseconds 5 GENACKs @ 0.8 milliseconds each= 4 milliseconds = 28 milliseconds total, each full handshake Y To complete 4 full handshakes (simply a rule of thumb), the vehicle would need to be in the footprint for 112 milliseconds. If the agency requires 100 mph operation, the vehicles travel one foot in 6.8 milliseconds. At this speed, the footprint would need to be 16.
Lane Tuning Guidelines • The downlink and uplink source frequencies and interference from lanes sharing same or close frequencies • The antenna-tag orientation Y RF power is the most important RF factor in lane tuning. Thirty dBm translates to onewatt nominal power. Increasing the RF power will, in general, increase the footprint.
MPI 6000 Multi-Protocol Reader System Guide ATA Tag Protocol TBD IAG Tag Protocol TBD Frequency Considerations — Multiple Protocols Y TBD Antenna-Tag Orientation P R E LI M IN A R Antennas need to be oriented to match the tag orientation (Figure 4-2). Antennas also need to match the tag placement and vice versa. For example, if the tag is placed in the center of the windshield, the antennas should be placed overhead, centered, or nearly centered in the lane.
A R Y Lane Tuning Guidelines P R E LI M IN Figure 4-3 Upper Center Interior Windshield Tag Placement Figure 4-4 Correct Exterior Tag Placement Antenna Uptilt Angle Adjusting the antenna uptilt angle directly affects the footprint and the point of first tag read (Figure 4-5). As expected, a greater uptilt angle will move the point of first tag read farther from the antenna.
MPI 6000 Multi-Protocol Reader System Guide ing license plate tags. M IN A R Y Note: TransCore does not recommend placing the antenna uptilt angles at less than five degrees. LI Figure 4-5 Overhead Antenna Tilt Angle Antenna Positioning Within the Lane P R E In lanes where the antennas are mounted side by side, TransCore recommends that you install the transmit antenna toward the driver side of the traffic lane and the receive antenna toward the passenger side of the traffic lane.
Lane Tuning Guidelines enable you to operate the lane at a lower RF power, which is usually the preferred operational mode.

A M IN LI E R P Y R
Chapter 5 Optimizing MPI 6000 Reader System Performance Y This chapter provides information to optimize the MPI 6000 performance and reduce cross-lane interference. R Cross-Lane Interference in RFID Systems M IN A Radio frequency identification (RFID) systems are subject to various types of interference that can affect the level of communications between a tag and a reader system. A type of interference that can result from the operation of the reader system is called cross-lane interference.
MPI 6000 Multi-Protocol Reader System Guide Identifying Cross-Lane Interference Cross-lane interference is identified by an area in the RF read zone, or footprint, which has areas where a tag cannot be read. If a toll lane has been operating satisfactorily and then begins to show a degradation in system performance, that is, an increasing number of missed reads or a spotty read pattern, there is a probability that crosslane interference is occurring.
Optimizing MPI 6000 Reader System Performance Diagnosing Cross-Lane Interference To diagnose this type of interference, first set the RF power in all lanes to a moderate setting of 6 to 9 decibels (dB) for both downlink and uplink antennas. Next, tune a single lane. When tuning a lane be sure to use a tag and vehicle that have been used consistently at your site. Y Once the lane has been tuned and you determine that it is working satisfactorily, perform lane tuning procedures in the adjacent lane.
MPI 6000 Multi-Protocol Reader System Guide Time-Division Multiplexing In situations where cross-lane interference can occur in an installation, and frequency management is not sufficient to solve the problem, you may need to use time-division multiplexing (TDM). By using the TDM function in readers, individual readers operate only during interleaved time periods.
Optimizing MPI 6000 Reader System Performance Because the TDM signals are based on RS–485 signals, you can extend the length of the TDM bus by using RS–485 repeaters or by using fiber with converters. Either of these two modifications should be used only when absolutely necessary in situations where the TDM lengths need to exceed the 1000-foot (305-m) maximum distance. Table 5-2 shows the pin designations and descriptions for the TDM connector.
A R Y MPI 6000 Multi-Protocol Reader System Guide Figure 5-3 Typical Plaza Configuration Using TDM P R E LI M IN The frequency settings and the 9-millisecond TDM time slots were determined based on a Title 21 tag transaction. For other installations, the frequencies and TDM duration need to be determined based on the type of transaction and expected vehicle speeds for that installation. Figure 5-4 shows a timing diagram for the readers in each of the time slots.

Master reader TDM synchronization period equals 30 milliseconds. A Note: The TDM synchronization period is set in 1.
MPI 6000 Multi-Protocol Reader System Guide TDM bus in the event of either a TDM connection failure, or a failure of the TDM circuit in the master reader, which also reduces the number of readers that will generate TDM failure messages in any one of these failure scenarios. Physical Remedies R Warning Switch off RF power before working on antennas. Y By adjusting the angle or position of the downlink and uplink antennas, you may be able to minimize cross-lane interference.
Optimizing MPI 6000 Reader System Performance LI M IN A R Y Adjusting the Antenna Side Angle In the eGo 4110A Reader System, you can adjust an antenna’s side angle so that the RF transmits toward the center of the toll lane, placing the RF footprint into the lane. If the side angle is too small, the footprint can project into the lane nearest to the tilted antenna.
