Murata joined the LoRa Alliance and worked with STMicro and Semtech to design a low-power, micro-sized LoRaWAN module that supports multiple sensors and wireless protocols. The Murata CMWX1ZZABZ module has been certified by the wireless management department and can use ISM bands such as 868M and 915MHz in most parts of the world. The proven module provides developers with an excellent hardware and software LoRa platform.
What is "Lora" and "LoRaWAN"?
What is LoRa?
LoRa is an abbreviation for "Long Range". Ultra-long-range communication is achieved at the physical layer (PHY) with optimized energy efficiency and stable signals.
What is LoRaWAN?
Also known as LPWAN, LoRaWAN stands for Low Power Wide Area Network and is the global standard for IoT (Internet of Things). LoRaWAN is the underlying protocol of the LoRa Alliance.
The LoRa physical layer and LoRaWAN protocol are optimized for battery life and low-cost end devices, enabling batch deployment of applications such as asset tracking, supply chain, agriculture, smart city, smart building, smart home, smart metering, and more.

About LPWA
LPWA stands for Low Power Wide Area Wireless Technology. LPWA wireless technology supports IoT (Internet of Things) applications, which typically require lower power consumption and wider coverage. Although data transmission rates are relatively slower than existing wireless communication technologies such as WiFi, Bluetooth, mobile networks, etc., LPWA technology is expected to be widely used in IoT and M2M because it can reduce the power consumption of device connections.
What is LPWA?
LPWA operates at a lower cost and with higher efficiency. And support more devices on a wider coverage area, with better two-way. Some LPWA technologies use the Sub-GHz band for long-distance transmission.
According to market forecasts, 700 million IoT devices will be connected to the LPWA network by 2021. As of 2025, 11% of IoT devices will use LPWA connections, such as LoRa, Sigfox, LTE-NB1, etc., and the service market will reach $75 billion.
Main characteristics
| Long distance | Low power consumption | Low data rate |
| The terminal can be as far as 10 kilometers from the gateway | Battery life is up to ten years | Less than 5000bps, send optical messages multiple times a day |
application
Social infrastructure, smart houses, agriculture, environmental protection, medical, pharmaceutical, industrial, logistics, utilities (water, gas metering), energy, smart buildings, smart cities, smart parking, location tracking, consumer goods, etc.
