The overall architecture of the low-altitude economy encompasses three major sectors: the supply side, the demand side, and the regulatory side which are interrelated and pursue common development. The supply side exhibits new characteristics across production factors, technology, and industry; the demand side shows the core value of the low-altitude economy through diversified application scenarios; and the regulatory side provides support and assurance for the healthy development of the low-altitude economy. To propel the high-quality development of the low-altitude economy, the supply side should strengthen technology research and development and build infrastructure; the demand side should promote scenario opening and expand market demand; and the regulatory side should improve policy rules and enhance safety precautions. In this way, the low-altitude economy will emerge as a new engine driving future socio-economic progress.
The low-altitude economy is an emerging comprehensive economic form driven by low-altitude flight activities. Firstly, the industry driving forces of the low-altitude economy are studied, including four aspects: market, technology, policy, and regulation. Secondly, the research progress in the low-altitude field by standardization organizations such as ITU, 3GPP, IEEE, and CCSA is examined. Finally, in response to the technical challenges faced in air-ground networking, three commercial air-ground integrated communication networking solutions are proposed: single-carrier air-ground frequency-different scheme, dual-carrier air-ground frequency-different scheme, and dual-carrier air-ground frequency-same scheme, providing multiple options and possibilities for the development of low-altitude communication networks.
As an emerging economic model, the low-altitude economy demonstrates extensive application potential in various fields such as agriculture, logistics, transportation, emergency rescue, and cultural tourism. Its development relies on core technologies such as flight control systems, communication technology, perception and navigation technology, information technology, and data processing technology. However, with further development of the low-altitude economy, risks in network security and data security are becoming increasingly prominent, involving problems such as imperfect security supervision, high sensitivity of data, widespread networking of equipment, and high dependence on digital technology. To effectively address these risks, strategies such as improving top-level design, building a security protection system, promoting multi-party cooperation, innovating security services, building a technical system, and cultivating security professionals should be adopted, in order to promote the healthy, orderly, and sustainable development of the low-altitude economy.
The low-altitude economy, listed as one of the strategic emerging industries, has emerged as a pivotal direction for fostering new quality productive forces. The low-altitude intelligent Internet of Things (IoT) system is an effective approach to accelerate the development of the low-altitude economy on a large scale. The low-altitude intelligent IoT system is built upon the integration of air-ground networks, integrating diverse digital and intelligent capabilities such as navigation, meteorology, perception, and computing power. It aims to provide services such as connectivity, supervision, and computing power to empower the innovation of low-altitude applications. The low-altitude intelligent IoT system is poised to establish a new pattern in the low-altitude economy characterized by unrestricted flights, intelligent applications, and meticulous management.

The low-altitude economy, as a strategic emerging sector, requires guidance and regulation from the legal regime for its healthy and orderly development. In recent years, China’s low altitude economy has developed rapidly, but the legal guarantee system still has a certain lag and incompleteness, which is difficult to fully cover and effectively guide the diversified development of low-altitude economy. In this context, this paper systematically reviews and analyzes the relevant laws, regulations, and administrative normative documents related to low-altitude economy in China, then scientifically evaluates the problems existing in the current system, and puts forward reasonable suggestions. The purpose of this paper is to promote the establishment of a regulatory system to meet the development needs, so as to support the rapid development of low-altitude industry.
With the rapid development of emerging technologies such as unmanned aerial vehicles (UAVs) and intelligent logistics, the low-altitude economy is gradually becoming a new engine for driving economic growth. Integrated sensing and communication (ISAC), as an important feature of future mobile communication networks, can provide new capabilities such as detection, regulation, tracking, and obstacle avoidance for low-altitude targets on the basis of communication, promoting the vigorous development of low-altitude services. This paper explores the demand for ISAC technology in the development of low-altitude economy, and analyzes five key issues: insufficient wide area coverage, limited sensing accuracy, insufficient sensing credibility, complex and difficult global interference, and lack of systematic technical indicators in sensing. Corresponding technical solutions are proposed, which can serve as a reference for research and practice in related fields.

This paper introduces the sources of phase noise in high-speed coherent optical communication systems and its impact on optical transmission performance. Based on 400G capacity simulation, the performance differences under different laser linewidths and dispersion are compared. The results show that the limiting factors in high-speed coherent optical communication are mainly the phase noise of the laser and the equalization-enhanced phase noise generated by dispersion coupling in the transmission link. The digital multicarrier technology has stronger tolerance and can transmit longer distances than the single carrier technology.
