NTRODUCTION
The Wirnet iBTS station is part of the global Long Range Radio fixed network to provide M2M
connectivity link between low power end-point and Internet Access.
The gateway architecture is specifically designed for the needs of public networks operators.
Figure 1: LoRa Network topology
The Wirnet iBTS is based on “Next Generation LoRa” technology provided by Semtech
Company. It is compatible and interoperable with existing LoRa LPWAN and offers GPS-free
geolocalization features.
Wirnet iBTS architecture is completely modular and upgradable to offer multiple
configurations to cover different countries and areas around the world:
Please check the appropriate version for the dedicated country. Contact KERLINK if required.
The present document addresses all the above Wirnet iBTS versions.

1. Description of the Wirnet iBTS
1.1 Modular architecture
The Wirnet iBTS has a modular architecture allowing the operator to configure and upgrade
the gateway to fulfill its needs.
Thanks to the modularity the operator is able to choose:
-
The backhaul network: Ethernet or GPRS/EDGE/HSPA/CDMA/LTE
The unlicensed band (ISM) where to operate the LoRa LPWAN: 868MHz, 902-928MHz
or 915-928MHz
-
The number of channels to operate the LoRa LPWAN: 8 to 64
- The antenna interface: single (omnidirectional), dual (space diversity or dual
polarization) or tri (sectorization)
Four different modules can be integrated in the Wirnet iBTS:
• CPU Module, which includes the main following features:
o Power management of the Wirnet iBTS
o CPU
o Memories
o GNSS receiver (GPS)
• WAN Module, which provides the backhaul functionality:
o Backup battery
o 4G modem declined in 3 versions depending on the geographical area:
Europe
Americas
APAC
• LoRa module – LoRa LOC, which can be also derived in 3 versions :
o 868MHz (863-873MHz)
o 915MHz (902-928MHz)
o 923MHz (915-928MHz)
The Wirnet iBTS can integrate from one to four « LoRa modules ». In this particular “4 LoRa
modules” configuration, a specific “front-end” board and mechanical lid are used to combine
the four “LoRa modules” together (see §1.4.3 for further details).
In its maximum size configuration, the Wirnet iBTS can then integrate six modules: one “CPU
module”, one “WAN module” and four “LoRa modules”.
The Figure 2 below shows an external view of the Wirnet iBTS:

1.2 Mechanical implementation for standard casing
1.2.1 Standard casing
The Wirnet iBTS station is built on a robust IP66 aluminum enclosure of 280 x 250 x 120 mm.
It is composed of two separated parts: the frame and a lid. The lid tightens to the frame
trough M5 screws, hidden by two plastic clip-on design covers.
A mounting kit is screwed on the back of the enclosure, allowing several mounting
configurations: wall mount, pole mount and metallic strapping.
The left and right sides of the enclosure integrate two waterproof screw-in vents to equalize
the pressure inside and outside. This reduces condensation by allowing air to flow freely into
and out of the sealed enclosure. At the same time, they provide a durable barrier to protect
the internal modules from contaminants like dust, sand, water, etc … improving reliability,
safety and longer product life.
The bottom side of the enclosure is dedicated for the connectors:
• 1 x M25 cable gland used to introduce the Ethernet cable (PoE) inside the enclosure
• 3 x N-SMB adapters used as RF interfaces for the antennas:
o 1 for GNSS antenna (GPS)
o 1 for WAN antenna (GSM/HSDPA/LTE)
o 1 for LoRa antenna. The number of LoRa antenna interfaces can be extended
to 6.
• 8 x M16 blind stops. They are considered as provisions for N-SMB connectors to be
used for additional antennas (LoRa or WAN) or external power supply cable gland.
Blind threaded standoffs are inserted in the rear side the enclosure. They are used to screw
and maintain the modules inside the enclosure. The modules can be easily inserted and
extracted for maintenance and upgradability purposes.
The Figure 4 below shows the different components inside the enclosure.

1.3 Mechanical implementation for compact casing
1.3.1 Compact casing
The Wirnet iBTS Compact station is built on a high impact resistant IP67 polycarbonate wall
mounting cabinet that withstands harsh industrial and outdoor environments.
It offers excellent flammability rating, good UV resistance and also good chemical resistance.
The dimensions of the cabinet are 260 mm x 170 mm x 120 mm.
It is composed of two separated parts: the frame and a lid. The lid tightens to the frame
trough two hinges that can be opened or closed by simple clipping. No screws are required
but only optional.
A mounting kit, with embedded antenna brackets, is screwed on the back of the enclosure,
allowing several mounting configurations: wall mount, pole mount and metallic strapping.

1.4 Block Diagram
1.4.1 Common functionalities
The following figure describes the hardware architecture and basic principles that are
common to the many Wirnet iBTS versions. In this particular case, we consider a
configuration with one “CPU module”, one “WAN module” and one “LoRa Module”.
Figure 9: Common Wirnet iBTS block diagram
The Wirnet iBTS is power supplied by a PoE injector through the RJ45 cable.
The RJ45 cable is introduced into the enclosure through the M25 cable gland and connected
to the RJ45 connector of the CPU module.
An alternate option of power supply consists in using an auxiliary power supply (11V-55V DC)
and connects it to the Euroblock connector of the CPU module.
The CPU Module insures the main followings features:
o Power management unit
o Cortex A9 CPU
o Memories (8GB eMMC and 256Mb DDR)
o GNSS receiver (GPS) with one RF SMA connector to connect the GNSS
antenna
The CPU module is connected to the other modules through a back panel board allowing,
the management of all the modules inside the Wirnet iBTS.

The “WAN Module” provides the backhaul functionality. It includes:
o Backup battery
o A 4G Mini PCI Express module that can be declined in 2 versions depending on
the geographical area:
Europe and APAC
Americas
o The USIM card holder
o A RF SMB connector to connect a LTE antenna
o A 868MHz or 915MHz notch filter to avoid desensitization of the LoRa
receivers
The “LoRa modules” can be derived in 3 bands versions to address different countries:
o 868MHz (863-873MHz)
o 915MHz (902-928MHz)
o 923MHz (915-928MHz)
The RF front-end board is configured to support a single antenna (16 channels) or two
antennas (2x8 channels).

1.4.2 Standard version of Wirnet iBTS
The following figure describes the functional architecture for the standard Wirnet iBTS
version i.e. including from one to three “LoRa Modules”:
Figure 10: Standard Wirnet iBTS block diagram
The RF front-end board of the “Lora modules” can be derived in 3 bands versions to address
different countries:
o 868MHz (863-873MHz)
o 915MHz (902-928MHz)
o 923MHz (915-928MHz)
The RF front-end board is configured to support a single antenna (16 channels) or two
antennas (2x8 channels). This could lead then to a “six LoRa antennas” configurations in the
maximum use case (tri-sectors, dual polarization antenna for instance).
The GPS (GNSS) connector, the WAN (LTE) connector and LoRa connectors are available on
the bottom side of the enclosure. All antennas are external antennas.

The following figure describes the functional architecture for a “4 LoRa modules” version,
featuring a maximum of 64 channels.
Figure 11: Wirnet iBTS “4 LoRa modules” block diagram
In this particular configuration, the mechanical front-end lids and front-end boards of each
individual “LoRa Module” are removed. They are replaced by a bigger RF front end board
and front-end lid that combine the 4 LoRa modules together.
This bigger RF front-end board can be derived in 2 bands versions to address different
countries:
o 915MHz (902-928MHz)
o 923MHz (915-928MHz)
The 868MHz band is not available in this configuration.
The bigger RF front-end board is configured to support a single antenna (64 channels) or two
antennas (2x32 channels).
The GPS (GNSS) connector, the WAN (LTE) connector and LoRa connectors are available on
the bottom side of the enclosure. The antennas are all external antennas.
