Overview
The R900 IoT Gateway is a LoRaWANTM IoT gateway that supports the full range of LoRaWAN channels. The
hardware architecture supports two Neptune RF antennas, a GPS antenna, direct DC input power or Power over
Ethernet (PoE), and backhaul options including copper Ethernet and 3G/4G wireless. The gateway model specified
for deployments is the TEKTELIC Kona Mega T0004250. The connector panel for this model is shown below.
Figure 1 Gateway Connector Panel
Scope
This document serves as a supplement to the manufacturer’s documentation for each component of the gateway
system (referenced in the appendix) and serves as a pictorial installation reference only. For detailed installation
and safety information from the manufacturer of each system component, please refer to the referenced
documentation and any other documentation available directly from the component manufacturer before
beginning the installation process. This documentation is listed in Appendix A.

Page 4
Configurations
It is recommended to install the gateway at the top of the tower, although it can also be installed at the bottom as
shown in the following figure. The selected options for powering and cabling from the required materials list will
depend on the selected configuration. When the gateway is installed at the bottom of the tower, the RF coax is
longer and two extra jumpers are required per RF antenna. When the gateway is installed at the top of the tower, a
PoE injector is required between the UPS and gateway.
Figure 2 Gateway Placement
Please note, power should not be applied to the gateway via PoE and DC simultaneously.
The figure below illustrates the connections when using DC power or the PoE injector.

Appendix D - RF Antenna Best Practices
The following section highlights best practices for installing the antennas:
-Mount antennas as high as possible, in a location which provides clear line-of-sight (LOS) to connecting
devices. Note:
oNearby objects, including the antenna’s supporting structure can change the antenna pattern and
cause areas of limited coverage
oWater towers often block the line of sight path between antenna and the connecting devices,
reducing coverage in some directions.
oOn traditional 3-leg and 4-leg towers, the standoff mount for the antenna must position the
antenna at least 5 feet away from the tower to minimize coverage area problems
-The Neptune RF antennas should have a minimum horizontal separation of 6 feet (1.8 meters). Maximum
performance is achieved by a horizontal separation of approximately 12-20 feet (3.6 to 6 meters).
-For sites with multiple antennas, mount the antennas one above the other if possible. Separate each
antenna by 10 (3 meters) feet to minimize interference.
-Antenna sites that must share space with multiple transmitting systems may require additional equipment
to protect the systems from interfering with each other. These sites could also require additional
engineering to make them perform well
-Managed antenna sites can require additional equipment and might dictate how an installation is to be
performed. Follow the site's requirements if the installation meets Neptune's minimum requirements.
-The antenna must be carefully hoisted up the tower so that it is not damaged.
-The feed line should not be attached to the antenna while it is being hoisted up the tower or other
supporting structure. The feedline should be attached after the antenna is in place.
-The antenna connector must not be damaged during installation. A damaged connector can result in
additional signal loss or complete failure of the RF connection.
