Encompass 4 Reader
General Information
Overview
Within the United States, TransCore Encompass 4 systems are authorized for
modulated operation with center frequencies in the range of 911.75 to 919.75
MHz and for continuous wave (CW) operation in the 902.25 to 903.75 and 910 to
921.5 MHz frequency ranges. These are the bands allocated by the Federal
Communications Commission (FCC) for this type of equipment. Modulated
protocols available on this reader can include eGo, Super eGo (SeGo), EPC,
and/or Interagency Group (IAG) with American Trucking Associations (ATA). ATA
protocol includes readers for vehicles and read-only rail installations that
use the S-918 standard of the Association of American Railroads. Up to two of
these protocols are available on a given Encompass 4 reader dependent upon
which version was specified. Because TransCore readers radiate more than 3
milliwatts (mW) of RF power, in this case from 0.2 up to 2W, the FCC must
license them under Section 90.351. This is accomplished by accessing the FCC
ULS (Universal Licensing System) webpage at https://www.fcc.gov/wireless
/universal-licensing-system, registering with the FCC, and filing online using
form 601, FCC Application for Wireless Telecommunications Bureau Radio Service
Authorization, along with the accompanying schedules. “Figure1 FCC ULS Home
Page” on page 1 shows the FCC ULS website homepage and Figure2 shows the
initial application screen. Only fixed readers are licensed. Transponders on
vehicles do not need a PT 90 license so uncheck Mobile on the application
screen.
Figure2FCC Application Screen
It is the user’s responsibility to define the operating frequencies required
consistent with the technical requirements of the E4 reader (no two adjacent
lane readers within 2.5 MHz of each other) and to file the proper application
with the FCC. Due to a significant FCC processing time of approximately three
months, this process should be started early in the design phase. Potential
interference between multiple readers in close proximity, that is, those
within 1000 feet with an unimpeded LOS (line-of-sight) between them, should be
identified early in the process so a suitable frequency plan can be developed
before applying for the license. The TransCore dealer can provide assistance
and support as necessary in completing the application.

FCC Licensing Guide
Table1 shows a list of FCC forms that are part of an LN Radio Service
application. The correct forms will be automatically generated on the FCC
website as you work through the online application process.
NOTE: In some instances it may be required to register an antenna structure
using the Antenna Structure Registration (ASR) online system (Form 854). This
is typically only for those installations requiring an antenna structure more
than 200 feet in height or for those near airport runways. The highest antenna
mounting of an LN Radio service reader is 30 feet above the ground, without
special waiver of the rule. If you are uncertain, review the ASR website,
which is accessible via the ULS website, or contact the FCC.
Governmental Entity: If you are considered a governmental entity as defined by the FCC, you can use provisions of 90.353i to simplify licensing on a blanket area basis, using “temporary fixed” locations, and a waiver request of Rule 90.137b. Governmental Entities also are exempt from FCC application and regulatory fees. Contact TransCore should you require examples of such applications.

Airport Identifier: In most cases, the Airport Identifier can be left blank
unless the proposed site is adjacent to an airport. Site Status: Determine if
the frequencies used for this system are to have Primary (P) or Secondary (S)
protection in conjunction with other fixed site facilities. This can be left
blank if the Commission’s rules do not recognize Primary or Secondary
protection. Otherwise, select P if primary protection is wanted for the site
or S for no protection. In most cases, the typical selection would be P.
Environmental Effect and Quiet Zones
Refer to Section 1.1307 of 47 CFR to determine if transmitting from this
location could have a significant environmental impact and answer the related
question accordingly. In most cases, this would typically be No. If the answer
is Yes, an environmental assessment will be required per 47 CFR, Sections
1.1308 and 1.1311. If the site is located in a quiet zone listed in Item 27b
of the instructions, then list the date the Quiet Zone entity was notified.
This can usually be left blank.
Antenna
NOTE: If you are a governmental entity and are using the blanket licensing
process, leave the Antenna information blank.
Select the location from the Select Location box and click on Add Antenna from
the Antennas box. Enter the data required when the screen populates. Note:
Although some locations may have multiple antennas, the FCC requires
information for only one antenna per location.
AAT: (above average terrain): height is not required in the CW bands (902.25
to 903.75 and 910 to 921.5 MHz) when the reader is configured for ATA-only.
Enter AAT in meters AMSL (above mean sea level) for readers operating in the
modulated band (911.75 to 919.75 MHz) for any of the other protocols (eGo,
SeGo, or IAG). Antenna height: Enter in meters AGL (above ground level).
Azimuth: Typically not applicable since it may not be known in advance. Refers
to the angle in the horizontal plane of the antenna main lobe with respect to
true north. The azimuth angle can range from 0° to 360° and defaults to north
(0°) if nothing is entered. Polarization: For nearly all installations,
properly mounted antennas imply horizontal (H) Polarization for the system.
Gain: Beamwidth and Gain are antenna parameters that can be found in Table2
for TransCore antennas, under columns entitled Peak Gain (dBi) and Horizontal
Beamwidth (deg). If you use other manufacturers’ antennas, use their stated
values for beamwidth and gain. If the Polarization and Gain fields are left
blank, then default values of vertical (V) polarization and 6 dBi gain are
used. However, NONE of these parameters should be left blank. Note: If the
antenna to be employed is not listed in Table2, contact TransCore Technical
Support for the required information.

*Line losses not accounted for. In units of watts, ERP = EIRP/1.64. In units of dBm, ERP = EIRP – 2.15 dB.
Because the Encompass 4/SmartPass 4 readers typically seen in the field come
with an internal antenna, the figures shown in the first row will apply in
most cases. Encompass 4 readers with internal antennas can be identified by
part number 10-400Y-0xx and model number 05530-yy.
For readers equipped with the optional port for an external antenna (P/N: 10
-401Y-0xx and M/N: 05531-yy), any of these antennas could be employed
depending on application requirements. Parameters shown in Table2 for peak
gain and beamwidth are nominal figures based on specifications, not actual
measurements. The actual figures seen in the real world can vary due to
factors such as frequency, temperature, manufacturing tolerances, etc.
NOTE: The maximum ERP limit for Part 90 operation is 30 W which is about 44.8
dBm. This corresponds to an EIRP of 49.2 W or 46.9 dBm.
When complete, press Save and then proceed to the Frequency page.
Frequency
Select Location: Highlight the location in the Select Location box and select
the antenna in the Select Antenna box, then click on Add New Frequency .
Lower or Center Frequency: Input the center frequency of each reader at each
location. Encompass 4 Readers use only one frequency, but if this is a reader
that uses multiple frequencies, enter each frequency and emission designation.
Upper Frequency: This field is optional and may be left blank.
Frequency Carrier: This field is optional and may be left blank.
Be sure to enter the center frequency to be used, not the band edge: eGo/SeGo
and IAG interrogation downlink modulated frequency band is licensed on center
frequencies of 911.75 to 919.75 MHz.
ATA CW may use frequency bands of 902.25 to 903.75 MHz and 910 to 921.5 MHz
within the United States.
TransCore Proprietary

FCC Licensing Guide
Wider emissions must be completely within the sub-band when applied to the
center frequency. For example, some older RFID systems used an emission
bandwidth of 6 MHz total, which means they must be at least 3 MHz from the
band edges. The sub-band edges are 902 to 904 MHz for the CW carrier ATA or
un-modulated backscatter uplink, and 909.75 to 921.75 MHz band edge for
modulated downlinks of other protocols. Applicants should also note that use
of the sub-band 919.75 to 921.75 MHz is on a shared basis with another radio
service. The FCC will want an acknowledgment of such an understanding and will
often return an application asking for such confirmation. To head off such a
time delay, it is recommended that a short note stating that the applicant is
aware that this sub-band is shared with another radio service and if (in the

Follow-Up
Once you receive the license you have one more step the build-out
notification.
Be sure to keep your FCC registration information and licensee information
current. It is TransCore’s understanding that there is no fee for an
administrative update to change name of person, address, or phone number.
Change of ownership or company name requires FCC consent in advance through
FCC transfer of control form 603, which is filed online. There is a
consummation follow-up notification associated with this process. If
contacted, be sure to respond promptly to all FCC inquiries, and remember to
renew your license, which typically operates on 10-year terms.
Build-out Notification
If you obtain a regular permanent license (generally not applicable to a
blanket license), you need to also notify the FCC when the station is
constructed. Your license copy will have a build-out notification date that is
one-year from the grant date start of the license term.
NOTE: Be sure to follow up with this required notification because those new
sites will automatically be TERMINATED approximately one year later.

FCC Licensing Guide
Typically, a licensee has 8 to 12 months from the date of issuance of a
license to complete construction and then notify the FCC that the frequencies
are in use at each location. This rule section 90.155 (of 47 CFR-Code of
Federal Regulations) is now enforced by a computerized process. The FCC wants
to ensure its ULS database is current and accurate. To accomplish this, the
FCC has chosen to use the above-described termination methodology as a means
of attaining this accuracy if:
1. Your permanent FCC license has been granted for an RFID/AVI system in the
LN radio service (the code for narrowband non-multilateration location
systems, that is, any 902 to 928 MHz AVI system requiring a Part 90 license
such as TransCore’s equipment), and
2. Your license has a construction deadline You must file the required
construction notification before the construction deadline (typically the
first year) expires, and within the timely period of 15 days of completion.
Otherwise, the license will be terminated. The FCC Public Notice for build-out
notification can be found at: https://www.fcc.gov/wireless/support/knowledge-
base/universal-licensing-system-uls-resources/ constructioncoverage For
further details on guidelines and instructions regarding build-out
notification contact TransCore Technical Support.

Exhibit A
The purpose of this Exhibit is to provide additional information in support of
the attached application for authorization of an automatic vehicle monitoring
(AVM) station(s) under Section 90.351 of the Rules, specifically in the LN
nonmultilateration Radio Service. The accompanying application proposes to use
an Amtech E4 reader with internal antenna that will be mounted permanently.
The FCC ID equipment authorization grant is FIHE4PT90V5.
Eligibility
The applicant is eligible under the Sections of Part 90.351 of the FCC Rules.
The applicant will use the proposed automatic vehicle monitoring facility to
identify vehicles that have been tagged by or in cooperation with the
applicant.
Nature of the project and public interest showing
By this request, the applicant seeks to operate an AVM system. The system is
to be installed is designed to identify vehicles as they approach the
facilities specified herein. The installation will serve the public interest
in that it will provide for more accurate and rapid identification of
vehicular traffic thereby increasing both efficiency and safety of the
applicant’s operations.
Description Of System Operation (47 Cfr 90 .351)
This section supplies a detailed description of the manner in which the
proposed system will operate. As such, it provides the information required by
Section 90.351 of the Rules.
Introduction
The TransCore technology consists of tags (transponders), and readers
(interrogators). The system works by having a reader send out a radio
frequency beam toward a tag. The tag modifies a portion of the signal and
reflects it back to the reader. It is the reflected signal that carries the
identification code. These tags are attached to an object such as a vehicle,
or railcar. When the object approaches a reader, an identification code is
retrieved electronically from the tag. The reader then relays the
identification code to a computerized management system. The tags can be
either beam-powered (no battery) or battery-powered, but neither type emits an
identification signal unless interrogated by a reader. Beam-powered tags use
the signal energy from the reader to power the tag circuitry. There is no RF
transmitter on either backscatter version of the tag. Thus, the tag is not a
transmitter and does not contain components to generate RF signals. This
slight modification of the signal includes the unique identification code of
the tag. This method of communication is called modulated backscatter. The
battery-powered tags stay energized at all times, and battery life is not
affected by the number of times a tag is read. IAG active transmission tags
are also covered by this application. They are compatible with tolling systems
in the northeastern part of the United States. The block diagram of Figure4
indicates the function of each component. The RF Module transmits an
interrogation signal in the direction of a tag. The RF Module receives the
reflected signal from the tag and relays this information to the Reader. The
Reader decodes the information contained in the tag and relays the information
to a host computer for subsequent use to identify, track and schedule the
tagged objects. The actual installation will use a single antenna integrated
with the reader for easy mounting on a wall or relatively short pole.

Figure4Block Diagram of the RF Module, Reader, Antenna, and Tag
Description of System Operation
RF Module
The RF module is composed of an RF oscillator, RF processor, homodyne
receiver, and preamplifier. The RF module is responsible for transmitting and
receiving radio energy. RF energy is generated by the RF oscillator and
amplified by the RF processor. This energy is transmitted through the antenna,
and the RF energy reflected by the tag is also received by the same antenna.
For SeGo, a separate downlink interrogation frequency is often used. The RF
module transmits the uplink frequency of RF energy and receives that same
frequency after is reflected as a modulated signal from the tag. Transmitter
output power is typically 2 watts or less. Maximum effective radiated power
(ERP) is as indicated in this application. Actual ERP will often be less than
the maximum in order to operate with the least power that will provide
reliable service. Some products incorporate RF module components in the
reader, which may also house the antenna.
Reader
The RF module receives the modulated signal from the tag and passes the data
to the reader. The reader decodes the data and performs error checking,
reporting the tag number to the controller. This low power signal will be
continuously directed at the area into which tagged vehicles will travel.
Accordingly, we request authority for continuous transmission.

FCC Licensing Guide
Antenna
The reader system uses a single antenna to transmit and receive RF energy to
and from the tag. Note that the antenna is for localized coverage in a
specific direction; the antenna does not have omnidirectional coverage
patterns. Because the antenna will be mounted less than twenty (20) feet above
ground and is normally canted downward, no height above average terrain has
been calculated.
Tag
The tag is composed of the modulator, power, code generator and clock, memory,
and antenna circuits. All of the tag’s circuits are located on a single
printed circuit board. The clock circuit sequences all circuit functions such
that information stored in the memory circuits is conveyed to the reader
system within precise timing. The information stored in the memory circuit is
permanent, and is a unique code that is specified by the owner prior to
installation of the tag onto its respective object (container, rail car,
truck, etc.).
Amtech has the capability of producing two versions of the tag: battery-
powered and nonbattery-powered. Regardless of whether the tag has a battery or
not, a tag does not transmit RF energy, it only reflects energy transmitted by
the reader system.
The tag conveys 64, 128, or 256 bits of digital information (depending upon
model) by modulating the reflected energy. The reflected energy is modulated
by varying the efficiency of the tag’s antenna. IAG tags contain an active
transmitter.
The homodyne receiver is used to separate the transmitted CW energy from the
information reflected by the tag.
Bandwidth
The reader emission designation is 685KL1D for the transmitted downlink to the
tag.
In order to accommodate the bandwidth of the signal transmitted by the reader,
backscatter uplink bandwidth is 110 kHz: Emission Designation 110KN0N for the
uplink. When reflected from the tag, however, this signal spreads over a wider
bandwidth. The occupied bandwidth of the reflected signal is about 2.5 MHz.
Vehicle Location Update Rates
The vehicle location update rate is every time a tagged vehicle passes a
reader location. At such times, its tag ID is read and the vehicle’s location
is updated.
Power and Modulation Techniques
Each reader emits a coded interrogation signal. The system specifications are
listed in Table3:

System Codes
Some tag products are coded in Weigand format. Character usage, other products
use a binary field sub-field definition. Other tags use the SeGo format,
organized into 64 bit pages. IAG data is 256 bits of data transmitted with
Manchester Coding following the 20 microsecond interrogation pulse
Statement of Interrogation and Reply Formats
The newer SeGo protocol is also used in some installations, having a higher
signaling rate, but no sub-bit encoding, rather using a checksum.
Planned Installation
The applicant anticipates installation of the number of transmitters specified
on the application within twelve months of the grant of this application and
will provide the FCC the Construction Build-out Notification within that 12
month period.
Prior Licensing History
The Commission has granted a host of identical or similar applications
throughout the 902-904 and 909.75 to 921.75 MHz band previously.
Implementation Schedule
Describe when installation will start and when operation will start. Wording
should include the phrase “after the FCC license is granted.” Note: this
application may take 2 months or more for processing.
