RADIO FREQUENCY HEALTH LIMITS FOR ENCOMPASS 4 READER USING AN EXTERNAL

ANTENNA IN FREQUENCY BAND OF 902.25 TO 903.75 AND 910.00 TO 921.50 MHZ

Several agencies (OSHA, FCC, IC) have environmental guidelines regulating maximum permissible exposure (MPE) or “safe” exposure levels that this product falls under. To ensure that proper safety guideline for the end users of this product, i.e. Occupational (Controlled) and General Population/ Public (Uncontrolled), the recommended levels for each of the agencies are presented in the next sections with TransCore’s recommendations for safety in the last section.

OSHA (Occupational Safety and Health Administration)

OSHA (an agency of The United States of America) legislates in the Code of Federal Regulations (CFR) Title 29 Part 1910 Subpart G 1910.97 titled “Nonionizing radiation”, a maximum safe exposure limit of 10 milliwatts per square centimeter (mW/cm

2) during any 0.1-

hour period (i.e. 6 minutes). Using the frequency (in the middle of the band of operation of this equipment) of 915 MHz and the highest antenna gain that this equipment is certified for use in a final installation, the minimum safe distance was calculated to be 8in (20cm).

FCC (Federal Communication Commission)

FCC (an agency of The United States of America) legislates in the Code of Federal Regulations (CFR) Title 47 Chapter I Subchapter A Part 1 Subpart I Section 1.1310 titled “Radiofrequency radiation exposure limits” that the maximum permissible exposure (MPE) is the following:

Occupational/Controlled Exposure

Power density = frequency(in MHz)/300 mW/cm

with an Averaging time of 6 Min

General Population/Uncontrolled Exposure

Power density = frequency(in MHz)/1500 mW/cm

with an Averaging time of 30 Min

Using the frequency (in the middle of the band of operation of this equipment) of 915MHz and the highest antenna gain that this equipment is certified for use in a final installation, the minimum safe distance was calculated. The MPE minimum distances are 14in (36cm) for the Occupational/Controlled environment, and 31.5in (80.5cm) for the General Population/ Uncontrolled environment.

Industry Canada (Innovation, Science and Economic Development Canada)

Industry Canada (a Department of the Government of Canada) sets out the requirements in Radio Standards Specification RSS-102, Issue 5 guidelines, recommending a maximum safe power density in W/m

2. Thus, the

Encompass 4 Reader System Guide

maximum permissible exposure for general population/ uncontrolled exposure at 915MHz is 2.77 W/m2. The average time is 6 minutes. The maximum permissible exposure (MPE) is the following:

Controlled Environment

Power density = 0.6455*frequency(in MHz)

0.5

W/m2 with a Reference Period time of 6 Min

General Public/Uncontrolled Environment

Power density = 0.02619*frequency(in MHz)

0.6834

W/m2 with a Reference Period time of 6 Min

Using the frequency (in the middle of the band of operation of this equipment) of 915MHz and the highest antenna gain that this equipment is certified for use in a final installation, the minimum safe distance was calculated. The MPE minimum distances are 18in (45cm) for the Controlled environment and 47in (120cm) for the General Public/Uncontrolled environment.

LIMITES D’EXPOSITION AUX RADIOFRÉQUENCES POUR LE LECTEUR ENCOMPASS 4

UTILISANT UNE ANTENNE EXTERNE SUR LA BANDE DE FRÉQUENCES DE 902.25 À 903.75

ET DE 910.00 À 921.50 MHZ

Plusieurs organismes (OSHA, FCC, IC) publient des directives environnementales qui recommandent des limites d’exposition maximale autorisée (normes MPE) ou des niveaux d’exposition « sûrs » auxquels cet appareil se conforme. Pour faire en sorte que chaque utilisateur final ait connaissance des directives de sécurité qui le concerne, que ce soit dans son travail (accès contrôlé) ou pour la population générale/le grand public (accès non contrôlé), TransCore présente les niveaux recommandés par chaque organisme dans ses recommandations sécuritaires détaillées dans la dernière section.

OSHA (Occupational Safety and Health Administration)

Dans le Code des réglementations fédérales (CFR), Titre 29, Partie 1910, Sous-partie G

1910.97, intitulée « Nonionizing radiation » (Rayonnements non ionisants), l’OSHA (organisme américain) recommande un plafond d’exposition maximale de 10 milliwatts par centimètre carré (mW/cm

2) pendant une période de 0,1 heure (soit 6 minutes). En utilisant la

fréquence de 915 MHz (milieu de la bande de fréquences d e cet appareil) et le gain d’antenne maximal pour lequel cet appareil a reçu une certification d’utilisation dans une installation finale, la distance minimale sécuritaire est de 20 cm (8 po).

How It Works

The Encompass 4 Reader System directs the RF module to generate an RF signal, which is broadcast through the integrated or external antenna. Entering the Encompass 4 Reader System’s reading range, a T ransCore RFID tag installed on a vehicle or other

object to be tracked adds its programmed identification information to the signal and reflects the signal back to the Encompass 4 Reader System. The Encompass 4 Reader System receives this modified, or modulated signal, and decodes the tag data carried by the reflected signal and transmits this data to a local host computer for processing.

Licensing Requirements

An FCC license provides the user with the legal authorization to operate the Encompass 4 on the licensed frequencies at the site specified in the license. Only an authorized installer or service technician can set the RF frequency of the Encompass 4 Reader System to the frequency specified in the FCC site license.

The FCC license may provide the user with protection and authorization to maintain the system should any other RFID product be used in the licensed area after the Encompass 4 equipment is installed.

Users of the Encompass 4 Reader System in the United States must obtain a license from the FCC. In the United States, the authorized modulated frequency band for this product is 911.75 to 91 9.75 MHz and the authorized continuous wave frequency band is 902.25 to 903.75 MHz and 910.00 to 921.50 MHz.

Introduction

The user is responsible for filing the FCC license according to FCC regulations, but the TransCore dealer will provide assistance and support as necessary to complete these forms. Forms are available online at the FCC internet site www.fcc.gov/Forms/

Form601/601.html or you can file online at wireless.fcc.gov/index.htm?job=online_ filing. For further information on obtaining the license contact TransCore.

This chapter discusses site plan development for installing the

Encompass

Note: In this section, unless specifically stated, "Encompass 4 Reader" applies both to the Encompass 4 Reader with integrated antenna and Encomp ass 4 Reader with external antenna.

Developing a site plan provides the foundation for the site’s system design and establishes the following system configuration parameters:

4 Reader System.

• Number and general location of primary components

• Number of different radio frequencies required

Gathering relevant site information is crucial before applying for Federal Communications Commission (FCC) approval and ordering and installing Encompass 4 Reader(s) and tags.

Also, consider the following factors when developing a site plan:

• Type of tags used in the facility

• Reader and/or antenna and tag alignment

• Site layout and traffic flow

• Encompass 4 Reader and/or antenna mounting requirements

• Encompass 4 Reader electrical requirements

• Encompass 4 Reader communications requirements

These factors provide relevant information regarding each site’s physical and electromagnetic environment and the conditions under which the system must perform.

Reading of Mixed Population T ags

The Encompass 4 Reader reads TransCore’s Super eGo® (SeGo) protocol tags, the American Trucking Association (ATA) and International Organization for Standard ization (ISO) read-only tags, whether powered by battery or beam, application-specific integrated circuit (ASIC)-based tags with Intellitag technology, or Inter-Agency

If the tags are not in the recommended loca tion, reliable optimum operation requires lower vehicle speeds.

Site Layout and Traffic Flow

The following site layout and traffic flow considerations are critical when determining Encompass 4 Reader installation locations:

• The Encompass 4 Reader read zone

• Other Encompass 4 Reader units and antennas in the area

Figure 2-2

• Lane configurations

• Reflection, refraction, and diffraction of RF signals

• Existing signal interference at the site

The Encompass 4 Reader Read Zone

The Encompass 4 Reader must be able to read the tag data properly within a specified area, called the read zone, without reading other nearby tags or interfering with other Encompass 4 Readers at the site. The following are some of the factors that affect the size and shape of the read zone:

• Mounting method used (pole or wall mount)

• Mounting location (overhead or side mount)

• Height from the ground and mounting angle

• Mounting method used (pole or wall mount) of the antenna

• Mounting location (overhead or side mount) of the antenna

• Height from the ground and mounting angle of the antenna

2-12

• Indoor or outdoor location

• RF output attenuation

• Range discrimination setting

• Other sources of interference and reflection

Developing the Site Plan

The Encompass 4 Reader must be positioned to allow the RF return from the tags within the designated range and be placed in an area where it is not likely to be bumped out of alignment. If the antenna becomes misaligned or some nearby structure is added or removed, system operation can be seriously affected.

TransCore recommends that traffic be guided through a controlled lane to consistently obtain accurate tag readings and to prevent physical damage to the Encompass 4 Reader and antenna.

Reflection, Refraction, and Diffraction of RF Signals

RF signals can be reflected, refracted, or diffracted by metal objects, walls, and even wet pavement or ice. Any of these factors can alter or degrade system performance. When designing your site plan, you must consider permanent structures and transient factors in the vicinity that may affect RF signals being generated by the Encompass 4 Reader. Permanent structures include buildings, chain link fences, guard shacks, and gates. Transient factors include passing tr affic and local weather conditions, such as rain or snow. Symptoms of reflection, refraction, and diffraction include reading tags that are out of the desired read zone or tags being read from another lane.

The most common RF reflectors are tially reflected by nonconducting materials suc crete. When nonconducting materials in the system increase reflection of RF signals.

as shielding, absorbing, range sensitivity adjustment, or barriers can also be used. See

Chapter 9, ”Troubleshooting and Maintenance” for more information.

Existing Interference

Interference from RF and electrical sources can degrade system performance and must also be considered in the site design. Fluorescent lights, neon signs, nearby radio sta tions, or power lines can interfere with the optimal operation of the system. The mag netic impulse noise from relays that control gate opening and closing can also disrupt the RF signal.

Interference may degrade both reader and tag performance. Existing interference at the site may be shielded, removed, or positioned further from the Encompass 4 Reader and/or antenna. In some cases, changing the operating frequency of the Encompass 4 Reader may provide a simple solution. Readers in proximity should have at least a 2 MHz frequency separation. See

13.

Strong RF sources of any frequency, in proximity to the tag, can preclude the tag

receiving the reader interrogation (see Chapter 9, ”Troubleshooting and Maintenance” ).

“Other Encompass 4 Readers in the Area” on page 2-

Electrical and Communications Requirements

All construction work at the site must be completed before installing the Encompass 4 Reader. Electrical and communications cables should be installed according to all applicable local and federal building code requirements. Specific instructions for posi tioning and installing the Encompass 4 Reader are discussed in Chapter 4, ”Installing

the Encompass 4 Reader”

Junction Box

Use a watertight junction box that meets applicable local and national building codes for connecting power and communications wiring. The junction box houses the termi nal strip for power and communications connections. TransCore recommends a NEMA Type-4 junction box with a back mounting panel.

Power and Communications Cables

Cable length for power and communications depends on the physical characteristics of the Encompass 4 Reader installation site. cabling options based on your site’s requirements.

Input/Output Circuits

To connect the Encompass 4 Reader to external equipment such as a treadle or traffic control light, install wires from these devices at the junction box. The Encompass 4 Reader input circuit is designed to connect to a dry contact closure. The Encompass 4 Reader output circuits are single-pole, double-throw relays providing dry contact clo sures. These contacts are rated at 42.2V AC peak (30V

mum with noninductive load. Output circuits are not intended for the direct control of electromechanical devices

such as motorized gates and barrier arms. For such applications, the Encompass 4 Reader output circuits should be used to drive a secondary, appropriately rated high-power relay.

Choosing, Installing, and Removing Tags

Installing eGo Plus License Plate Tags

Metallized coatings on some vehicle windshields and windows absorb the RF energy emitted by the Encompass 4 Reader, thus causing tags to be misread. You must use exterior LPT s on vehicles with metallized coatings on their windshields and windows.

Use license plate installation techniques to install tags on the exterior of vehicles that have this type of window coating.

Note: The read zone of an overhead Encompass 4 Reader should be adjusted accordingly when an exterior tag is installed on a license plate, or the read zone will be reduced.

Required Materials

• Screwdriver (flat-blade or Phillips depending on the vehicle’s license plate

mounting screws)

• Optional TransCore Exterior T ag Accessory Kit (19077-01). This kit contains

tamper-resistant mounting screws and wrench.

• eGo Plus LPT

Positioning eGo Plus License Plate Tags

The eGo Plus LPT is installed over the license plate at the upper part of the vehicle’s front license plate area.

Note: If your state does not require a front license plate, install the LPT in the area where the license plate would normally be mounted. If your vehicle does not have a front license plate area, contact your tag agency for other tag options.

The orientation of the tag is important. The tag must be mounted so that the holes on the tag base plate are on the top edge.

eGo Plus LPT Installation Procedures

To mount the eGo Plus LPT

1. Remove the screws from the license plate area of your front bumper (Figure 3-

13). If your vehicle does not have mounting screws you will need two self-

To remove an interior ATA-protocol tag installed using double-sided tape, slowly pry off the tag with a thin tool, such as a putty knife.

Installing ATA License Plate Tags

Metallized coatings on some vehicle windshields and windows absorb the RF energy emitted by the Encompass 4 Reader, thus causing tags to be misread. Use exterior LPTs on vehicles with metallized coatings on windshields and windows.

Choosing, Installing, and Removing Tags

Use license plate installation techniques to install tags on the exterior of vehicles that have this type of window coating.

Note: The read zone of an overhead Encompass 4 Reader should be adjusted accordingly when an exterior tag is installed on a license plate, or the read zone will be reduced.

Exterior tags may be installed on metal or plastic bumpers using the existing license plate bracket and hardware.

The tag can be mounted on the front bumper where the license plate is normally located or mounted directly to the front license plate or license plate bracket. Once installed, the face of the tag should be pointing directly forward or slightly upward. If the bumper, license plate, or license plate bracket has any material that overhangs the tag, the tag will not function properly.

Required Materials

You need the following supplies to install license-plate mounted tags:

• Exterior LPT

• Two 0.25-inch (.63 cm) bolts and nuts (user-supplied). Length of the bolts can

vary depending on vehicle model.

• Screwdriver and wrench (user-supplied)

• 0.25-inch (.63 cm) spacers or washers (if needed). Thickness of spacers can vary

depending on vehicle model.

Positioning ATA License Plate Tags

The orientation of the tag is important. The tag must be mounted so that the holes on

the tag base plate are on the bottom edge. See Figure 3-22.

Figure 3-22 Proper Tag Orientation

When positioning the tag, observe the following guidelines:

• The tag should be horizontal and parallel to the ground.

• The tag face should be perpendicular or tilted slightly upward.

• The tag may lean to the rear a maximum of 30 degrees.

• The tag may lean to the front a maximum of 10 degrees.

holes in the tag with the holes in the front bumper where the license plate would normally be located. See Figure 3-23.

3. Insert bolts through the tag base plate holes

and the holes in the bumper or the

holes in the upper portion of the license plate area. See Figure 3-24.

Figure 3-26 Spacer Positioned Behind Tag

6. Tighten the bolts and nuts with a screwdriver and wrench to secure the tag to the vehicle.

Types of Bumpers

When mounting tags directly to a bumper, consider the following factors:

• Tags can be mounted on any metal or non-metallic surface; composition of

bumper does not matter.

• Tags can be mounted to plastic bumpers using self-threading screws.

• Metal bumpers should be pre-drilled; self-threading screws may be used.

Alternate Mounting Locations

If the exterior type tag cannot be mounted on the license plate bracket or directly on the bumper, it may be mounted on a relatively vertical front surface of the vehicle. The exterior tag should be mounted as close to the bumper as possible, following all guidelines regarding orientation, obstruction, and overhang given fo r bumper mounting. For applications where the exterior tag can be mounted on a smooth flat surface using double-sided tape.

Required Materials

Exterior tags need to be installed on a relatively flat surface. You need the following materials to install exterior tags:
