INTRODUCTION
The Wirnet iBTS gateway 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 compatibility.
Wirnet iBTS architecture is completely modular and upgradable to offer multiple
configurations to cover different countries and areas around the world:

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:
x The backhaul network: Ethernet or GPRS/EDGE/HSPA/CDMA/LTE
x The unlicensed band (ISM) where to operate the LoRa LPWAN: 863-873MHz (aka
868MHz), 902-928MHz (aka 915MHz)or 915-928MHz (aka 923MHz)
x The number of channels to operate the LoRa LPWAN: 8 to 64
x The antenna interface: single (omnidirectional), dual (space diversity or dual
polarization) or tri (sectorization)
Four different modules can be integrated in the Wirnet iBTS:
x CPU Module, which includes the main following features:
o Power management of the Wirnet iBTS
o CPU
o Memories
o GNSS receiver (GPS)
x 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
x LoRa module – LoRa LOC, which can be also derived in 4 versions :
o 868MHz (863-873MHz)
o 915MHz (902-928MHz)
o 915MHz 64 Highway (902-915MHz uplink, 923-928MHz downlink)
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”.

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:
x 1 x M25 cable gland used to introduce the Ethernet cable (PoE) inside the enclosure
x 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.
x 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 5 below shows the different components inside the enclosure.

The modules are screwed on the blind threaded standoffs to build the Wirnet iBTS according
to customer requirements.
The modules are tightened all together with two mechanisms:
x the back panel board connectors,
x the wing screws assembling the mechanical sides (radiators) of the modules
SMB-SMB cables are provided to interconnect the RF interfaces of the modules to the SMBN adapters, on the bottom side of 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.
