Robustel introduces an innovative LoRaWAN gateway for IoT

Robustel specializes in the development and production of a wide range of IoT communication devices, including industrial routers and LoRaWAN gateways. Robustel is now introducing its latest innovation, the R1520LG LoRaWAN gateway. Thanks to its exceptional features and functions, this very affordable device is the optimal solution for a wide range of deployments in the Internet of Things (IoT).

The Robustel R1520LG is a new and unique LoRaWAN gateway that operates at a frequency band of 868 MHz. The LoRaWAN (Long Range Wide Area Network) wireless network is designed for data transmission between IoT (Internet of Things) devices and a central control system. It is an energy-efficient, long-range network, providing wireless connectivity that enables communication over long distances, even in hard conditions such as urban areas. For this reason, the gateway is suitable for a wide range of applications, from industrial IoT environments to large buildings and smart cities, wherever a large volume of data needs to be processed. With support of 4G, 3G, 2G and WiFi technologies, the Robustel R1520LG provides a robust and reliable connection to various devices and sensors in the IoT environment.

A specific possible scenario of using the LoRaWAN router is in sharing electricity within the community energy sector within municipalities. Two buildings where a PV plant is installed on one roof and shares the produced electricity with the other building. The buildings are distant no more than 500 meters and the control and communication takes place in the LoRa network.

Another application of this solution can be in an apartment building, where radiator sensors for remote reading of heat (calorimeters) are installed and these sensors communicate with the Robustel R1520 LORA router. Imagine that you have a whole range of such sensors for measuring humidity, temperature, weather conditions, etc. And all these sensors communicate with one router, which will process this data for you and you can evaluate it very easily.

With an integrated Chirpstack LoRa network server, the router effectively manages the operations. The R1520LG is equipped with a variety of interfaces, including 2x Ethernet, 1x RS232, 1x RS485 and USB 2.0, enabling connection to a wide range of devices. The robust metal cover offers mounting options on a DIN rail and on a wall.

Advanced connection options

Using advanced connectivity options including Chirpstack LNS and Modbus to Cloud integration, the R1520LG gateway offers unmatched connectivity and enables problem-free data transfer and management. Thanks to a robust 4G cellular network and built-in WiFi 802.11b/g/n with AP function, users can stay connected anywhere, anytime, even in remote locations.

Problem-free installation and operation

The R1520LG brings the option of PoE-PD power supply, meaning it can be powered via an Ethernet cable, which is also used for data transmission. The user-friendly interface and intuitive controlling make it easy to configure and manage, ensuring a smooth use for users of all levels.

 The RobustOS operating system and free RCMS service

The Robustel R1520LG uses the RobustOS operating system, which is based on Linux and designed for use in Robustel devices. Another advantage is the free RCMS service, which enables management and monitoring of remote devices, data collection, diagnostics and remote configuration of devices connected to the Internet, thus minimizing operational overhead expenses. The gateway supports a VPN network that enables a secure connection to the Internet and security of data transmission between the device and the end network.

E2C Chirpstack software connector

The Gateway is equipped with an E2C Chirpstack software connector, which enables the connection of LoRa sensors directly to AWS and Azure cloud environments. Together with the E2C Modbus this connector enables getting the data easily from wired and wireless sensors to the cloud.

Key features of the Robustel R1520LG gateway:

• POE support
• WiFi client and AP support
• Supply voltage 9 to 60 V DC
• Dual Ethernet ports providing WAN and LAN connectivity
• Two SIM slots for resistant mobile communication
• RS232 and RS485 interfaces
• Operations Console support
• RobustVPN provides easy remote access to all devices
• SIM / Internet connection
• E2C Chirpstack software connector allows connecting LoRa sensors directly to AWS/Azure or other cloud platforms

With its advanced features, robust connectivity options and affordability without compromising on quality or performance, the LoRaWAN Gateway R1520LG by Robustel represents a significant step forward in IoT connectivity. Its compact design, scalability, security and longevity provide new possibilities in a complex solution for a wide range of applications and industries in IoT projects.
