2. LoRaWAN™ is a Low Power Wide Area Network (LPWAN) specification intended for wireless battery operated Things in
regional, national or global network. LoRaWAN target key requirements of internet of things such as secure bi-directional
communication, mobility and localization services. This standard will provide seamless interoperability among smart Things
without the need of complex local installations and gives back the freedom to the user, developer, businesses enabling the roll
out of Internet of Things.
LoRaWAN network architecture is typically laid out in a star-of-stars topology in which gateways is a transparent bridge relaying
messages between end-devices and a central network server in the backend. Gateways are connected to the network server via
standard IP connections while end-devices use single-hop wireless communication to one or many gateways. All end-point
communication is generally bi-directional, but also supports operation such as multicast enabling software upgrade over the air
or other mass distribution messages to reduce the on air communication time.
Communication between end-devices and gateways is spread out on different frequency channels and data rates. The selection
of the data rate is a trade-off between communication range and message duration. Due to the spread spectrum technology,
communications with different data rates do not interfere with each other and create a set of "virtual" channels increasing the
capacity of the gateway. LoRaWAN data rates range from 0.3 kbps to 50 kbps. To maximize both battery life of the end-devices
and overall network capacity, the LoRaWAN network server is managing the data rate and RF output for each end-device
individually by means of an adaptive data rate (ADR) scheme.
National wide networks targeting internet of things such as critical infrastructure, confidential personal data or critical functions
for the society has a special need for secure communication. This has been solved by several layer of encryption:
Unique Network key (EUI64) and ensure security on network level
Unique Application key (EUI64) ensure end to end security on application level
Device specific key (EUI128)
LoRaWAN has several different classes of end-point devices to address the different needs reflected in the wide range of
applications:
Bi-directional end-devices (Class A): End-devices of Class A allow for bi-directional communications whereby each end-
device's uplink transmission is followed by two short downlink receive windows. The transmission slot scheduled by the end-
device is based on its own communication needs with a small variation based on a random time basis (ALOHA-type of
protocol). This Class A operation is the lowest power end-device system for applications that only require downlink
communication from the server shortly after the end-device has sent an uplink transmission. Downlink communications from
the server at any other time will have to wait until the next scheduled uplink.
Bi-directional end-devices with scheduled receive slots (Class B): In addition to the Class A random receive windows, Class B
devices open extra receive windows at scheduled times. In order for the End-device to open its receive window at the
scheduled time it receives a time synchronized Beacon from the gateway. This allows the server to know when the end-device
is listening.
Bi-directional end-devices with maximal receive slots (Class C): End-devices of Class C have nearly continuously open receive
windows, only closed when transmitting. Class C

4. The Unizen LoRa Expertise
Unizen LoRa expertise enables IoT applications by using various
LoRa RF transceivers from different vendors that are embedded
into sensors and gateways to capture and transmit data over long
ranges using minimal power. In addition, the LoRa Alliance™ has
developed an open protocol based on LoRa technology called
LoRaWAN™ to help ensure that all the devices, servers and
software components on LPWANs are interoperable with each
other and deliver secure communications in IoT, M2M, smart city,
and industrial applications.
The LoRa Alliance, is a non-profit organization of nearly 400
members focused on standardizing LoRa for IoT/M2M and
creating a strong ecosystem to scale the technology.

Unizen Technologies has sound expertise in building
solutions using technologies that are driving the market
today around the Internet of Everything revolution.
Internet of Everything is based on the idea that everyday
objects can be readable, recognizable, locatable,
addressable, and controllable via the Internet. The Internet
of Things (IoT) is a scenario in which objects, animals or
people are provided with unique identifiers and the ability
to automatically transfer data over a network without
requiring human-to-human or human-to-computer
interaction. IoT has evolved from the convergence of
wireless technologies, micro-electromechanical systems
(MEMS) and the Internet
Unizen has good relationship with semiconductor majors
like Texas Instruments, Semtech, NXP-Freescale, Analog
Devices, Cypress, Pericom, Microchip, and Atmel which
helps to get support and critical materials required for
product solutions.
LoRa is a wireless technology developed to create the low-
power, wide-area networks (LPWANs) required for
machine-to-machine (M2M) and Internet of Things (IoT)
applications. The technology offers a very compelling mix
of long range, low power consumption, deep indoor
coverage, and secure data transmission and is gaining
significant traction in IoT networks being deployed by
wireless network operators.
LoRa Technology is built into chipsets from Semtech, ST
Micro and Microchip. It is also built into the products
offered by our vast network of IoT partners and integrated
into LPWANs from mobile network operators worldwide.
Through our work with the LoRa Alliance, our goal is to lead
and help foster a complete ecosystem that can provide
entrepreneurs, small businesses and large enterprises with
all the tools they need to develop their own IoT solutions
and bring them to market.
