What is the difference between the power factors of the Internet of things terminal NB-IoT and LoRa
发布时间：2019/10/15
To do comparative analysis of NBIOT and LoRa, we must first consider the Internet of things are two important factors in the power consumption of the terminal node is needed, the current consumption (peak current and average current) and the contents of the agreement. The synchronization protocol of the cellular network requires that the terminal must be connected regularly and have a short downlink delay. LoRaWAN uses an asynchronous ALOHA protocol, which requires a regular wake up terminal, and the terminal can be dormant, long or short, according to the requirements of the specific application scene.

The design of the cellular network is designed to improve the utilization of the spectrum, and the cost of the node and the battery life are sacrificed accordingly. In order to reduce the cost and prolong the battery life, the LoRaWAN node will have a certain lack of spectrum utilization.
The nature of work is the demand of the terminal nodes of network coverage, for NBIoT one obvious advantages can be achieved by upgrading the existing network infrastructure to provide network deployment. One of the prominent advantages of the LoRa industry chain is that the members of each link are autonomous, and they can determine the scope of the network on its own.
Anyone can install and run a LoRa network. If we want to support roaming or mobility, LoRa needs to sign different contracts with different network operators. Besides, different operators also have different QoS problems. The activity of LoRa is open, but also lies in the defect of openness of the network itself will inevitably lead to the fragmentation of mobility services cannot operate, security problems have gradually put on the agenda of the LoRa, LoRa security solutions are needed to achieve additional security integrated networking, network operators have a natural advantage in technology based on this point, which does not require additional security integration is excellent.
NBIoT and LoRa difficult to see which technically has the absolute advantage, the biggest difference between the two is working in the licensed spectrum. Due to the existence of interference, non licensed spectrum products only for a few days will be based on authorized and non authorized spectrum has become the key to the future development of NBIoT and LoRa technology.
NBIoT and LoRa respectively will shine in the operation level and enterprise level LPWAN. Between the two is benign competition and cooperation, as the representative of the authorized spectrum to NBIoT and LoRa as the representative of non authorized spectrum starting from their respective advantages to complementary forms of business.
