Low power narrowband wireless communication technology requirements for smart buildings
Senior iot expert Gan Quan
Gan Quan introduced that at present, the national standards related to smart buildings are mainly concentrated on the wiring and design-related construction requirements, while the national standards related to smart building network systems and information systems are still blank.
Therefore, the formulation of the "Low-power narrowband wireless Communication Technology Requirements for Smart Buildings" can not only further standardize the planning and construction of low-power wireless networks for smart buildings, provide technical support for the application of wireless communication technology in smart buildings, but also further promote the development of wireless communication technology solutions in the field of smart buildings.
According to Oasis, the standard has submitted a technical requirements document in May this year, and it is expected that the Standards Court will formally establish the project and solicit opinions this year, and issue a formal industry standard in 2025.
The exploration of digital intelligence in space operation management and the application of LoRa technology
Chen Feilie, general manager of Operation Optimization Center of Shanghai Electric Group Digital Technology Co., LTD
In the space digital technology scenario, Internet of Things technology is faced with many challenges such as compatibility between different protocols, data security and privacy, data transmission rate, equipment energy consumption, signal coverage and so on.
In this case, there is a need for a technology that can help achieve lightweight implementation, low-cost deployment, sustainable operation, and data analysis.
At the same time, physical space and digital space continue to interact, influence and drive, forming a new "space twin".
Chen Feilie said that around the "LoRa technology + space twin "generated by the combination of smart space and communication solutions, it is to the enterprise operation management refined and" people-oriented "experience as the goal, to build integrated control, sustainable iteration of the number of intelligent space.
This scheme can reduce the continuous investment of managers, carry out refined control of energy saving and cost reduction, promote the continuous optimization of enterprise management, and extend more scenarios with the iteration of artificial intelligence technology.
When LoRa met the Apocalypse Satellite Internet of Things
Hao Li, product director of Beijing Guodian High-tech Technology Co., LTD

Secondly, management business is a basic need, the application of Internet of Things technology for "business management, system implementation, standard landing" service, so that the system application personnel become the master of the system!
Then, equipment stability is the core, ubiquitous Internet of Things technology gradually permeates to the control region, how to provide more stable iot sensor data is the core issue of the next step in the construction of smart power plants.
Finally, network security is the key, the severe international struggle situation continues to pull up the "security" bottom line, equipment security, network security, data security is the eternal theme of smart power plant.
Discussion on LoRa physical layer optimization technology
Wang Lu, associate professor, Shenzhen University
Synsensory integration technology is an innovative solution that integrates communication and perception functions. By integrating communication base stations, satellite communications, positioning, drones and other key infrastructure, a collaborative network system is formed to provide seamless communication and high-precision perception services.
Wang Lu discussed the possibility of synaesthesia of LoRa from the technical level.
A soft demodulation algorithm based on likelihood ratio is used to dynamically adjust demodulation parameters to improve the communication performance, and high confidence symbols are selected in the soft demodulation communication module to obtain the channel state information.
From the experimental results, the use of existing commercial nodes, without modifying LoRaWAN, without adding additional sensors, can indeed improve the communication capability and get the perception function.
