Myth 1: Data security
In the era of the Internet of Things, with the increase of the number of connected devices, people pay more attention to the security of data transmission. Gan Quan, director of LoRa market strategy in Semtech China, said that data security can be discussed from two directions, one is the wireless communication security at the physical layer, and then is the system level:
First of all, LoRa is a kind of frequency expansion and frequency modulation technology, which can be transmitted under the noise. The transmission mode of this physical layer is highly hidden, safe and not easy to be found. From the wireless point of view alone, the security of LoRa technology is very high, which is higher than the current civil wireless communication technology, including 5G, 4G, Wi-Fi, etc.
The second is at the system level, including the network layer, networking and encryption mode. On the system layer, you can use a variety of different encryption methods according to the requirements, such as when using the LoRaWAN protocol, you need to use three layers of encryption. LoRa Cloud And LoRa Edge also provides cloud-to-end secure encryption, which is encrypted inside the chip, and can be used alone. Semtech Fully consider the customer needs of all aspects. For very high-level encryption, it provides encryption from the cloud to the end. Some customers need small cost, simple and convenient solutions, Semtech can also provide the simplest way to connect, let customers to choose the encryption method. LoRa's encryption method is more flexible and advantageous, with Semtech providing a variety of security-level encryption solutions.
Myth 2: LoRa and NB-IoT
To put it simply, there is no competitive relationship between the two: "who replaces who". LoRa technology was launched many years earlier than NB-IoT, and it has had a high degree of recognition and recognition in the market in the early stage. The market scale of the Internet of Things is very large, and the application market of LoRa is also very wide. For the fragmented application Internet of Things application scenarios, LoRa can give developers more space to play freely, and can provide optimization for customers from the point to the end and the cloud. For customers who want to innovate freely, LoRa has a high degree of automatic control and free choice, from connectivity to networking to applications. In the long run, LoRa is very promising in the private network sector.
In the private network + public network scenario, LoRa and NB-IoT are very suitable for complementing each other. LoRa has the characteristics of self-group, security, controllable, can support customers to fully control from the connection, networking to the final application platform, with a high degree of flexibility.
Myth 3: Is LoRa being restricted?
China's Ministry of Industry and Information Technology clearly regulated the requirements for the use of LoRa wireless technology in China in its Announcement 52 issued in 2019. For example, the output power and contract time are regulated. In fact, LoRa in China can be used in 470 MHz band and 433 MHz band, and meets the specification. The main direction of LoRa in China is the application of private network. Among all kinds of wireless communication technologies known in the market at present, LoRa has the characteristics of self-group, security and controllable, and LoRa solution is more suitable in agricultural pastures, warehouses, buildings and other use scenarios. Therefore, the national regulations not only did not limit LoRa, but also the introduction of corresponding requirements enhanced the market's confidence in the application of LoRa, and vigorously promote the orderly and healthy development of the industry.
