What is the difference between Lora wireless water meter and NB IoT wireless water meter?
LoRa (Long Range) and NB IoT (Narrowband Internet of Things) are two high-profile low-power wide area network communication technologies that have important development prospects in IoT applications. Although both focus on IoT applications with low bandwidth, low power consumption, long-distance, and large-scale connectivity, there are differences in many aspects.
LoRa technology is an early low-power wide area Internet of Things technology. It adopts linear frequency modulation spread spectrum modulation technology with excellent reception sensitivity, which can achieve longer communication distances and resist interference by using different spread spectrum sequences. The concentrator/gateway of the LoRa network can simultaneously receive and process data from multiple nodes, thereby expanding the system's capacity.
On the contrary, NB IoT is a technology with wide coverage, support for large-scale connections, lower power consumption, and low module cost. It focuses on the low-power wide area Internet of Things market and can be widely applied globally. NB IoT uses proprietary licensed frequency bands and supports various deployment methods such as in band, protected band, and independent carrier, allowing it to coexist with existing networks.
There are also differences in application between LoRa and NB IoT. LoRa technology plays an important role in the field of embedded wireless communication, while NB IoT places more emphasis on achieving the interconnection of everything in the Internet of Things. This is because NB IoT has advantages such as low power consumption, wide coverage, low cost, and high capacity, and is suitable for multiple vertical fields such as remote meter reading, asset tracking, intelligent parking, and intelligent agriculture.
In summary, LoRa and NB IoT each have their own advantages and are suitable for different fields. Choosing a suitable technology depends on specific application requirements, and factors such as communication distance, power consumption, deployment cost, and system capacity need to be considered. With the rapid development of the Internet of Things, both technologies will continue to play important roles in different scenarios.
