Introduction: The "network revolution" of low-altitude economy
When drone logistics networks cover the sky above the city, air taxis begin test flights, and power inspection robots shuttle between high-voltage towers, a trillion-level low-altitude economic market is accelerating. However, the large-scale development of this field has always faced two major bottlenecks: how to achieve high-precision real-time communication and how to build global security perception capabilities.
With the official commercialization of 5G-A (5G-Advanced) technology, the combination of synaesthesia integrated base stations and smart antennas is injecting breakthrough momentum into the low-altitude economy. At the beginning of 2024, China Mobile took the lead in deploying the world's first 5G-A synaesthesia integrated commercial base station in Shenzhen, marking the historic leap of the communication network from "information pipeline" to "perception-communication-computing power" fusion. This technological revolution driven by smart antennas may completely reconstruct the low-altitude industrial ecology.

‌1. Breaking through the barriers of technology: How can interawareness integration solve the low-altitude dilemma‌
Traditional low-altitude communications rely on satellite navigation and dedicated frequency band radars, which have many blind spots, long latency, and high costs. The 5G-A interawareness integrated base station achieves the integration of communication and perception capabilities through three core technological breakthroughs:

‌1. Smart antenna array: a "jack of all trades" for electromagnetic waves‌
The 128T128R massive MIMO antenna carried by the base station can both transmit 5G-A signals and receive reflected waves from targets such as drones and aircraft. Through the original ‌time division duplex perception algorithm‌, a single antenna array can switch between communication and perception modes within 0.1 milliseconds, achieving centimeter-level positioning and microsecond-level latency synchronization. Huawei's test data shows that its AirPON smart antenna has a three-dimensional positioning accuracy of ±10 cm for drones within 500 meters, far exceeding the ±1 meter level of traditional radars.

‌2. Multi-band collaborative perception: a balance between penetration and accuracy‌
Base stations operate in both Sub-6GHz and millimeter wave bands: low-frequency bands ensure penetration coverage in complex environments (such as between urban buildings), and high-frequency bands provide ultra-high-resolution perception. ZTE's UniSense solution successfully achieved group trajectory tracking of 200 drones over the Qiantang River during the Hangzhou Asian Games through ‌intelligent spectrum aggregation technology‌, with a bit error rate of less than 10^-8.

‌3. Cloud-edge-end collaborative architecture: computing power embedded in the communication network‌
Each base station has a built-in edge AI inference module that can process perception data in real time. China Unicom combines synaesthesia data with high-precision maps to build an "airspace digital twin system" in Xiongan New Area, compressing the warning speed of illegal drone intrusion from minutes to 50 milliseconds.

‌II. Commercial landing: from demonstration scenarios to thousands of industries‌
2024 is regarded as the first year of low-altitude economic scale-up, and the commercial use of integrated telepathy base stations is giving birth to multiple benchmark applications:

‌Scenario 1: "Air Highway" for UAV Logistics‌
SF Express and China Telecom have deployed 200 5G-A telepathy base stations in the Pearl River Delta to build the world's first low-altitude logistics communication network:

When the drone flies in the 200-meter airspace, the base station senses surrounding obstacles such as birds and high-voltage wires in real time and dynamically adjusts the route.

The communication bandwidth reaches 1Gbps, supports 4K video backhaul, and monitors the temperature and vibration data of the cargo warehouse throughout the process.

Test data shows that the average daily delivery trips of a single machine have increased by 3 times, and the crash rate has dropped from 0.03% to 0.001%.

‌Scenario 2: Urban Air Traffic (UAM) Management‌
The "Urban Low-altitude Traffic Brain" system of Shenzhen Pengcheng Laboratory realizes four major functions through telepathy base stations:

Aircraft digital identity authentication: millimeter wave perception can identify drone serial numbers to prevent "illegal flying".
Air traffic flow dispatch: Each base station tracks 100 targets at the same time and automatically plans conflict avoidance paths.
Emergency response: When a base station in a certain area senses that the drone is low on power, it immediately notifies the nearest charging station to land.
According to estimates, the system increases the utilization rate of low-altitude airspace in cities by 70% and the speed of accident response by 90%.
‌Scenario 3: Intelligent inspection of ultra-high voltage power grid‌
State Grid uses 5G-A telepathic base stations on the ±1100kV Jiquan line:

The base station has a perception radius of 5 kilometers and can warn of dangerous situations such as wildfires and ice cover 20 minutes in advance.
The inspection robot obtains real-time high-definition images through the base station, and the accuracy of AI defect recognition is increased to 99.5%.
The line operation and maintenance cost is reduced by 40%, and the fault repair time is shortened by 80%.
‌III. Industry Chain Resonance: Ecological Reconstruction from Equipment Vendors to Operators‌
The popularization of integrated telepathic base stations has promoted structural changes in the communications industry chain:

‌1. Equipment Vendors: From Selling Hardware to Selling Capabilities‌
Huawei launched the "Sensing-as-a-Service" platform, opening the base station sensing data interface, and logistics companies can pay by the number of calls.

Ericsson developed an integrated telepathic chipset to reduce the size of base stations by 30% and reduce power consumption by 25%.

‌2. Operators: Cross-border definition of new business models‌
China Mobile established a low-altitude economic division and launched a "one-kilometer airspace" package: companies can rent base station sensing capabilities at a price of only 1/10 of the price of self-built radar systems.

Deutsche Telekom and Airbus cooperated to develop an "airspace blockchain" based on telepathic base stations, and aircraft data was uploaded to the chain in real time for evidence.

‌3. Policy dividends: China leads the standard setting‌
The Ministry of Industry and Information Technology's "5G-A Telepathic Integration Technology White Paper" clearly defines the goal of building 100,000 low-altitude sensing base stations by 2025. Shenzhen was the first to legislate to allow synaesthesia data to be used for traffic law enforcement, and drone interference incidents fell by 95% year-on-year. According to ABI Research, the global synaesthesia integrated base station market will exceed US$22 billion in 2028, with China accounting for more than 50%.

‌Fourth, Challenges and Future: Infinite Possibilities from Low Altitude to Deep Space‌
Despite the broad prospects, the popularization of synaesthesia integrated base stations still faces three challenges:

‌Spectrum resource shortage‌: Communication and perception bands need to be dynamically shared. Nokia proposed a "federated learning spectrum allocation" solution to reduce the interference rate by 60%.
‌Privacy and security disputes‌: Base station perception data may leak commercial secrets. China Academy of Information and Communications Technology is taking the lead in formulating the "Guidelines for Low Altitude Data Security Classification".
‌Cross-industry collaboration problems‌: Aircraft manufacturers, operators, and cloud service providers need to unify data interfaces. ETSI (European Telecommunications Standards Institute) has started the formulation of relevant standards.
In the future, the path of technological evolution will gradually become clear:

‌Synaesthesia and computing integration‌: After 2026, base stations may integrate lightweight AI training capabilities to achieve "perception, learning, and decision-making".
‌Air-space-ground integration‌: China Star Network plans to interconnect telepathic base stations with low-orbit satellites to build a full-area perception network below 3,000 meters.
‌Green energy saving‌: Huawei's "intelligent sleep" technology can reduce the power consumption of base stations to 5 watts during periods without aircraft, reducing carbon emissions by 40%.
‌Conclusion: Redefine the "third capability" of base stations‌
When communication base stations evolve into "airspace sentinels" and when electromagnetic waves become the "invisible hand" that weaves a low-altitude safety net, the significance of 5G-A telepathic integration has surpassed the technology itself. It marks the first time that humans have built a digital "sixth sense" over the city, and equipped the low-altitude economy with a smart eye. In this industrial transformation led by the Chinese, the flashing of each base station is accumulating energy for the development of a trillion-level market blueprint - the future sky will surely be busier and more orderly due to technological innovation.
