HDL has launched the IoT smart gateway HL2100, a core device that enables wireless sensors to access public networks. Data is transmitted wirelessly between the sensors and the gateway via Sub-1GHz technology. The gateway features a built-in 4G wireless communication module, allowing it to remotely transmit sensor-collected information—via the 4G public cellular network—to a central monitoring hub, while also supporting the issuance of control commands. This device leverages a high-performance 32-bit dual-core processor, an ultra-low-power co-processor, and a robust wireless communication module, backed by an embedded real-time operating system that ensures seamless data transmission. The product is ideally suited for a wide range of applications across the IoT ecosystem, including smart factories, intelligent water management, precision agriculture, smart communities, and advanced fire safety systems. With this device, users can achieve cloud-based management and scheduling of wireless sensor nodes, paving the way for truly transformative IoT application systems.

Typical Applications

Characteristics

• Employs a high-performance 32-bit dual-core LX7 processor (with clock speeds up to 240 MHz), an ultra-low-power co-processor, and a full-fledged WIFI subsystem (802.11b/g/n);

• Supports wireless data transmission over Sub-1GHz networks, delivering high interference resistance, high sensitivity, low power consumption, and ultra-long transmission range;

• Low-power design supports multi-level sleep and wake-up modes, minimizing power consumption to the greatest extent;

• Built-in solar control chip allows direct use of the solar panel, eliminating the need for an external MPPT;

•WDT watchdog design ensures the device operates stably over the long term;

• Employs a comprehensive anti-disconnection mechanism to ensure the data terminal remains online at all times;

• Lightning protection for antenna interface;

• Supports 2.4GHz Wi-Fi for local parameter configuration and device OTA firmware upgrades;

• Smart data terminal, which can enter data transmission mode upon startup;

• Built-in standard TCP/IP (4/6) protocol stack, supporting transparent data transmission;

• Receive sensor information via 408–565 MHz and 816–1080 MHz Sub-1GHz signals

• Supports 4G LTE Cat1 communication

• The gateway can simultaneously receive information from up to 1,000 devices.

• If the gateway cannot connect to the internet or MQTT, the data received will be stored in the gateway’s memory.

• Can store data for at least 60 days (under specified operating conditions).

• Once the connection is reestablished, all data will be uploaded to MQTT in chronological order.

• Internal flash buffer for data processing and uploading.

• Able to list all RSSI readings for each detected Sub-1GHz device.

• Power, network, and battery status indicators. This button is used to turn the gateway on/off or reset it.

• On the settings page, options include the MQTT server address, IP address, Wi-Fi connection settings, and channel counts below 1 GHz, among others.

• Data will be pushed to the customer’s MQTT broker

The enclosure meets the IP67 protection rating.

Installation

It is recommended to install the equipment at a height of more than 2 meters above ground level, and whenever possible, choose a higher-lying location—such as an open area on a building rooftop with no surrounding obstructions. If special circumstances require installation in a basement, the site should be selected based on the actual conditions of the location. When mounting the equipment, it’s best to secure it to a sturdy, reliable wall; ensure that any drilled holes and expansion screws used for installation remain tight and stable. During installation, position the equipment as close as possible while still allowing the antenna to extend above the wall and remain free of nearby obstacles. Additionally, if there are tall obstructions like lightning rods nearby, make sure the minimum distance between the antenna and the obstacle exceeds 0.6 meters.
