LoRa126X Series LoRa Modules: Designed Specifically for the Internet of Things

The LoRa1262 is a series of LoRa front-end modules developed by NiceRF Wireless for IoT applications, utilizing Semtech's SX1262 and SX1268 chips. This series features a compact size, low power consumption, and high sensitivity. It is produced and tested in strict compliance with lead-free processes, meeting RoHS and REACH environmental standards. Additionally, the LoRa1262 series has obtained international certifications, including CE and FCC.

LoRa126X Series Models

The LoRa126X series includes four products, covering operating frequencies of 433/490/868/915MHz. Among them, the LoRa1268 can be customized for frequencies ranging from 410-810MHz, and the LoRa1262 can be customized for frequencies ranging from 150-960MHz. Notably, the LoRa1262-868 is CE certified, and the LoRa1262-915 is FCC certified.

Uses LoRa spread spectrum chips

The LoRa126X modules use Semtech's SX1262 and SX1268 chips, which employ LoRa spread spectrum and frequency hopping modulation technology. Their communication range and reception sensitivity far exceed those of existing FSK and GFSK modulation technologies. Multiple transmission signals can share the same channel without interference, providing excellent anti-interference capabilities.

High performance in a compact size

The LoRa126X series module is a high-performance LoRa long-range transmission module featuring a compact size, ultra-low receiving current, and sleep current. It has a built-in 64KHz crystal oscillator that can wake up the microcontroller in low-power mode. The module's antenna switch can be controlled by the module's internal chip, saving external MCU resources. The LoRa126X module, with its compact size and 160mW output power, achieves a receiving sensitivity of -148dBm under LoRa modulation, providing a significant advantage for battery-powered applications.

Low Power Consumption Design

The LoRa126X has two power management modes for receiving current: LDO and DC-DC. In DC-DC mode, the minimum receiving current is 4.2mA for FSK modulation with 4.8 kb/s data transmission. For LoRa modulation with a 125 kHz signal bandwidth at 1.8V, the receiving current is 8.2mA. There are minor variations in the receiving current for both LoRa and FSK modulation under the Boosted setting.

Similarly, in LDO mode, the receiving current is minimized for FSK modulation. With Boosted improvements, the receiving current for LoRa modulation with a 125 kHz signal bandwidth is 10.1mA.

Can be used as a gateway node

The SX126X series modules can serve as LoRaWAN gateway nodes, capable of building LoRaWAN systems with NiceRF's LoRaWAN1302 and LoRaWAN1303 gateway modules. LoRa gateways collect messages transmitted by LoRa nodes and forward these messages to LoRaWAN servers, enabling communication from devices to the cloud.

What is the difference between the LoRaWAN wireless module and LoRa gateway wireless transmission technology?

Many individuals find it challenging to differentiate between the LoRaWAN wireless module and LoRa gateway wireless transmission technology, as well as their applications within the realm of IoT.

LoRaWAN specifically pertains to the networking protocol found within the MAC (Media Access Control) layer. In contrast, LoRa serves as a protocol within the physical layer. Although current LoRaWAN networking implementations utilize LoRa as the physical layer, it's worth noting that the LoRaWAN protocol also allows for the use of GFSK (Gaussian Frequency-Shift Keying) as the physical layer in specific frequency bands. From a network layering perspective, LoRaWAN can adopt various physical layer protocols, just as LoRa can serve as the physical layer for other networking technologies.

LoRa, as a technology, falls under the category of LPWAN (Low-Power Wide-Area Network) communication technologies. It represents an ultra-long-distance wireless transmission method based on spread spectrum technology, pioneered and promoted by Semtech in the United States. This approach revolutionizes the previous trade-off between transmission distance and power consumption, offering users a straightforward system capable of achieving extended range, prolonged battery life, and increased capacity. Consequently, it expands the capabilities of sensor networks. Currently, LoRa predominantly operates within free frequency bands globally, including 433/868/915MHz, among others.

On the other hand, LoRaWAN wireless communication stands as an open standard defining the communication protocol for LPWAN technology based on LoRa chips. LoRaWAN defines the Media Access Control (MAC) layer at the data link level and is overseen by the LoRa Alliance. It's crucial to distinguish between LoRa and LoRaWAN because companies like Link Labs utilize a proprietary MAC layer in conjunction with LoRa chips to create more advanced hybrid designs, such as Link Labs' Symphony Link.

LoRaWAN typically employs a star or star-to-star topology, which is generally considered superior to mesh networks due to advantages such as conserving battery power and extending communication range. In a star topology, messages are relayed to a central server through gateways, and each end node can transmit data to multiple gateways. These gateways then forward the data to the web server, where tasks like redundancy detection, security checks, and message scheduling are executed.

In summary, LoRa encompasses solely the link layer protocol, making it suitable for point-to-point (P2P) communication between nodes. In contrast, LoRaWAN includes the network layer, allowing data to be sent to any base station connected to a cloud platform. By connecting the appropriate antenna to its socket, the LoRaWAN module can operate at different frequencies, offering versatility in its applications.
