Iot applications need to consider many factors such as node cost, network cost, battery life, data transfer rate (throughput), latency, mobility, network coverage, and deployment type.
Nb-iot and lora are two of the most promising low-power wide-area communication technologies, with different technical and commercial characteristics.
These two lpwan technologies have wide coverage, lte iot module many connections, low speed, low cost and low power consumption. They are both suitable for low-power Internet of Things applications and are actively expanding their ecosystems.
NB-IoT has obvious advantages in terms of bandwidth and time cost, and is constructed in cellular mobile networks, consuming only about 180KHz of bandwidth for enterprises, which can be directly deployed in UMTS networks, LTE networks and GSM networks, and can easily be upgraded to achieve the network.
At the same time, compared to 4G network, it supports long standby time, more efficient connection, and the battery life of the device through the networking technology has a high.
Network IoT application scenario advantage: Due to the low cost and low power consumption of network IoT technology, it is widely used in the fields of positioning, water meter and parking. For example, network IoT modules are built into shared bicycles to realize IoT communication.
It can make use of the operator's original room division system to complete coverage, and can push NB-IoT devices into users' homes through convergence packages and device experience.
It is widely used in industries such as smart home, smart retail and smart city.
Under the same power consumption condition, LoRa has attributes that can transmit longer distance than other wireless systems, thus realizing the unification of low power consumption and long distance.
The advantages of LoRa are ultra-low power consumption and multi-channel data transmission, increased system data capacity, and gateway and terminal system support for ranging and positioning, which is very suitable for location-sensitive applications.
