1Product Description
1.1 Introduction
This User Guide covers two systems. One system is referred to as the Mobile Gateway which is
comprised of a single module while the second system is referred to as the Fixed Gateway
which is comprised of two modules, the Gateway Module and the Tower Top Unit (TTU)
module. As used within this document, unless otherwise qualified, the term “Gateway” will
refer to the Gateway system which includes the Gateway module, the TTU in the case of the
fixed Gateway, and any accessories such as cables and antennas, etc. Reference to individual
components will generally use the qualifying term “module”.
1.2 Overview
The Pearl Gateway is a wireless base station which operates using LoRa or FSK modulation in
the North American ISM band of 902 MHz – 928 MHz with TDD operation across the entire
band. LoRa is a long range, low power wireless standard for Internet of Things (IoT) application
(https://www.lora-alliance.org/). The FSK modulation is customer proprietary. The Gateway is
designed to be compliant with FCC Part 15.247 as either a frequency hopping spreads spectrum
(FHSS) or Digital Transmission (DTS) System. The module has a single transmitter capable of
approximately +28 dBm maximum for the fixed gateway (conducted at the TTU antenna port)
and about +20 dBm at the mobile gateway antenna port.
Table 1-1 lists the Pearl system hardware.

Pearl Tower Top Unit
The Fixed Gateway is designed to operate always with the Tower Top Unit (TTU) which also
contains an LNA and as well amplifies the RF transmit signal. The TTU and antenna LNA are
powered from the Gateway which injects a bias supply voltage onto the RF antenna feed center
conductor. The Gateway RF antenna feed is protected against overload conditions and short
circuit conditions with an internal auto-resetting protection circuit.
Both Gateways support an active GPS antenna which is powered through the GPS antenna feed
from the Gateway. The GPS antenna feed is protected against overload conditions and short
circuit conditions with an internal auto-resetting protection circuit.

Both Gateways contain a number of ports for data management including USB and Ethernet.
The Fixed Gateway also contains binary alarm inputs for site management.

2Installation
2.1 Safety Precautions
•Installation, operation, and maintenance of the Pearl Gateway must only be performed by a
trained person who is aware of all hazards involved.
•The Pearl Gateway must be installed in a restricted access location (such that touching of
the Gateway by untrained persons is not likely).
•The Pearl Gateway may become hot to the touch during normal operation at elevated
ambient temperatures. The surface temperature of the enclosure may reach 90°C.
•The Pearl Gateway has no internal field serviceable parts. The Gateway module must only
be opened by an approved service center.
•All installation practices must be in accordance with local and national electrical codes.
•Do not work on the system during periods of lightning activity.
•The Pearl Gateway is considered permanently connected equipment. The Protective Earth
Ground connection to chassis is always required.
•Ensure the Pearl Gateway Protective Earth Ground connection is properly terminated prior
to the connection of any other interfaces.
•The Pearl Gateway TTU contains primary lightning surge suppression on the RF ports. The
primary lightning protectors have the ability to shunt lightning energy to earth ground
which includes the chassis. Ensure that the Protective Earth Ground connection is always in
place.
•Ensure that the Pearl Gateway including the TTU and its antennas and supporting structures
are properly secured to eliminate any physical hazard to people or property. The Gateway
including the TTU must be securely mounted according to the mounting instructions prior to
any cable connection and operation.
•The Pearl Gateway does not contain a power supply disconnection device; a readily
accessible disconnection device must be incorporated external to the Gateway.
•The Pearl Gateway shall be supplied through an input overcurrent protection device rated
not more than 20 A. The overcurrent protection must have the appropriate current
interrupt capacity for the power source and must be incorporated into the non-earthed
conductor(s) of the DC supply.

Pearl Gateway User Manual T0004906 Version 1.6
TEKTELIC Communications Inc. Confidential Page 16 of 52
•The DC input power positive pin must be at positive potential relative to the DC negative pin
for the Gateway to function. If the polarity is reversed, the unit will not sustain damage but
will not operate until the polarity is corrected.
•The Pearl Gateway DC power source must meet SELV requirements.
2.2 Unpacking and Inspection
The following should be considered during the unpacking of a new Pearl Gateway.
1. Inspect the shipping carton and report any significant damage to TEKTELIC.
2. Unpacking should be conducted in a clean and dry location when possible.
3. Do not discard the shipping box or foam inserts as they will be required if a unit is
returned for repair or re-configuration.
2.3 Required Equipment for Installation
The following tools are required to install the Pearl Gateway system:
1. An imperial and a metric socket with Torx set and a torque wrench.
2. Anti-oxidant compound (NO-OX-ID, Penetrox, Noalox, Ox-Gard or equivalent).
3. A small wire brush or emery cloth.
4. A clean cloth.
5. Weatherproofing tape kit for the RF connectors (Scotch Wireless Weatherproofing Kit,
WK-101 recommended).
6. Four M4 screws with locking hardware for Gateway mounting (length according to
application, see next section).
7. Four M8 screws with locking hardware for TTU mounting according to application (see
next section).
2.4 Pearl Gateway Mounting
The Pearl Gateway Modules are designed to be mounted to a flat surface using site supplied
M4 x 0.7 stainless screws with locking hardware, one at each of the four mounting points as
illustrated in Figure 6 for the Mobile Gateway Module and Figure 7 for the Fixed Gateway
Module. These four mounting screws are to pass through pre-drilled holes in the mounting
surface. The mounting drill-hole pattern is on a square as indicated in Figure 6 and Figure 7. The
dill size shall be selected for a slight clearance to M4 screws.
Mounting the Gateway module requires access to both sides of the mounting surface; this may
require two persons in cases where the mounting surface is large.

Pearl Gateway User Manual T0004906 Version 1.6
TEKTELIC Communications Inc. Confidential Page 17 of 52
The length of M4 mounting screw shall be determined according to the mounting surface
thickness. After accommodating for the locking hardware and mounting surface thicknesses,
the M4 mounting screws shall tread into the gateway chassis by at least 5 mm but not more
than 10 mm.
The Gateway Module mounting orientation is to be such that the chassis fins are vertical.
Ensure that the surface and related structure to which the Module is being mounted is secure
and able to support a dead load of at least 136 kg (300 lbs).
Ensure sufficient free space around the bulkhead connectors for access and cable ingress.

TEKTELIC Communications Inc. Confidential Page 18 of 52
Figure 7: Pearl Fixed Gateway Module Mounting Points
2.5 Pearl TTU Mounting
The Pearl TTU module is designed to be mounted to a flat surface or to a pole using the
supplied mounting brackets. The TTU may be mounted with two of the small brackets as
illustrated in Figure 9 or with one small bracket and one antenna bracket as illustrated in Figure
10. Each bracket shall be attached to the TTU module using four of the supplied M5 x 0.8 –
10mm stainless steel screws at the locations illustrated in Figure 8. Once the brackets are
attached to the TTU module, the module may be mounted.
To mount the TTU with bracket to a flat surface, four site supplied stainless steel M8 bolts are
required, two at each end of each bracket as illustrated in Figure 8 and Figure 9. The M8 bolts
shall be selected according to the site specific mounting surface material and shall include
locking hardware.

Pearl Gateway User Manual T0004906 Version 1.6
TEKTELIC Communications Inc. Confidential Page 19 of 52
To mount the TTU with bracket to a pole, two site supplied stainless steel pole straps are
required, one at each mounting bracket looped through the strap slots as indicated in Figure 8
and Figure 9.
The TTU mounting orientation is to be vertical with the vent plug pointing down to earth.
Ensure that the surface or pole and related structure to which the Module is being mounted are
secure and able to support a dead load of at least 136 kg (300 lbs).
Ensure sufficient free space around the bulkhead connectors for access and cable ingress.
