Health Limits for Encompass 4 Reader Using Integrated Antenna (902 to 928 MHz)

Within the United States, environmental guidelines regulating safe exposure lev­els are issued by the Occupational Safety and Health Administration (OSHA).
Section 1910.97 of OSHA Safety and Health Standards 2206 legislates a maxi­mum safe exposure limit of 10 milliwatts per square centimeter (mW/cm aged over 6 minutes at 902 MHz.
Although not binding, other organizations such as the American National Stan­dards Institute (ANSI) have issued similar guidelines that are more restrictive than the OSHA limits (ANSI C95.1). ANSI guidelines recommend a maximum safe power density in mW/cm

Frequency
(in MHz)
1500
Thus, the maximum permissible exposure for general population/ uncontrolled exposure at 902 MHz is 0.60 mW/cm
2
. The power limit is a six-minute average.
The RF power density generated by the Encompass 4 Reader was calculated using a maximum antenna gain of 9.5 dBi, equivalent to the antenna gain of the inte­grated antenna.
Warning
At 2 W transmitted power and a distance of 19.3 inches (49 cm) from the read er, the maximum power density calculated was less than 0.60 mW/cm
2
. Install the reader at least 19.3 inches (49 cm) from the general public. Maintenance per­sonnel must remain at least 8.66 inches (22 cm) from reader when system is operating.
The data confirms that the TransCore Encompass 4 Reader effectively meets OSHA requirements and thus does not represent an operating hazard to either the general public or maintenance personnel.

This document is intended to be used by authorized TransCore Encompass 4 Reader System dealers, installers, and service personnel. Because the Encompass 4 Reader System has no operator- or end-user serviceable components or features, no end-user manual or operator guide exists. Once the system is set up and tested by the authorized installer, Encompass 4 Reader System operation requires no end-user intervention.

System Guide Organization

Note: TransCore offers the Encompass 4 Reader in two models: one with an inte­grated antenna and one that r equir es connection to an external antenna. In this system guide, information and instructions for both Encompass 4 Reader models are pre­sented. Where separate instructions dictate, a section detailing one Encompass 4 Reader model is followed immediately with a section detailing the other reader model.

The Encompass 4 Reader System is a dual-protocol reader supporting the low-cost, high-performance SeGo radio frequency identification (RFID) technology . SeGo tech­nology provides the capability to read miniature RFID tags in a myriad of options including rugged, durable, or thin flexible forms such as the eGo Plus S ticker Tag. The Encompass 4 Reader System also supports legacy transportation applications such as gated toll, parking, or security gate access and is designed to be compatible with exist-

The Encompass 4 Reader System is a high-power unit that can read both half-frame and full-frame tags. The reader output power can be adjusted using reader commands.

Reader

The Encompass 4 Reader System consists of an input/output (I/O) module, a power supply, a reader logic board (also called a tag decoder), a radio frequency (RF) trans­mitter/receiver (called the RF module), and a patch antenna.
A second version of the Encompass 4 Reader is designed to be used with a high-per­formance external antenna. These Encompass 4 Reader System components are con­tained in a highly reliable, compact, and easy-to-install environmentally-sealed package. Figure 1-1 shows the front and side views of an Encompass 4 Reader Sys­tem.

Tags

The Encompass 4 Reader System has the capability to read TransCore SeGo protocol tags, the Intellitag-based eGo protocol tags, TransCore ATA protocol, and TransCore ISO-compliant read-only full- and half-frame tags, as well as IAG protocol tags.

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 ransCor e 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. No end-user-oper­ated controls exist on the Encompass 4 Reader System.
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.
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 http://wire-
less.fcc.gov/uls. For further information on obtaining the license contact TransCore.
