Fire Safety Training

To enhance all employees’ awareness of fire safety and improve their preventive consciousness, and to ensure that everyone becomes proficient in fire-fighting techniques, on November 7, 2023, our company invited Mr. Xu Tianhang from Yong’an Fire Protection Co., Ltd. to deliver a fire safety lecture in the company’s fifth-floor conference room. Managers, supervisors, and relevant staff from all departments of our company attended this training session.

Laser-based wireless power transfer opens the door to a new world.

According to an official press release from Ericsson, during this demonstration, the two parties successfully activated a fully “powerless” Ericsson Streetmacro 6701 5G millimeter-wave base station—without drawing power from the street grid or relying on on-site power generation—using laser technology developed by PowerLight Technologies. The demonstration achieved energy transmission of 480 watts over a distance of 300 meters (985 feet). The system consists primarily of two components: a transmitter and a receiver. At the transmitter end, electrical power is used to generate a highly intense light beam, which is then transmitted to the receiver. The receiver employs a specialized photovoltaic array to capture this beam, converting the incoming photons into electrical energy that can power any device connected to it. Kevin Zvokel, Head of Networks at Ericsson North America, stated that the laser-beam wireless power transmission solution enables safe, long-distance power delivery without the need for grid connections, thereby eliminating the obstacles posed by battery site selection during network deployment. This approach significantly reduces deployment time and enhances flexibility. Claes Olsson, Executive Chairman of PowerLight Technologies, noted that most people are already familiar with wireless charging technologies used in small electronic devices such as mobile phones and smartwatches. However, the demonstration conducted by Ericsson and PowerLight Technologies represents a breakthrough—a crucial step toward the commercialization of safe, wireless power transmission on a larger scale. Moreover, PowerLight Technologies is currently developing a system that will enable secure, wireless power transmission over distances of several kilometers within the next few years. This wireless transmission solution from Ericsson and PowerLight Technologies replaces traditional power cables, helping operators rapidly deploy base stations—particularly in urban pole-mounted sites and micro-stations. It is ideally suited for temporary scenarios requiring rapid deployment, such as emergency communications support or periods of high traffic demand. Additionally, this technology can conveniently power a wide range of IoT devices, including unmanned AGVs, drones, and sensors.

5G network construction requires continuous innovation.

Just as mobile phones have evolved from feature phones to smartphones, and despite the ever-increasing power of smartphone functions, battery technology has yet to see a breakthrough revolution, smartphone manufacturers have increasingly turned their attention to innovating charging technologies. After all, no matter how powerful the features or how advanced the hardware of a smartphone may be, without sufficient power supply, it’s just a “brick”—and the same holds true for 5G base stations. As we all know, 5G boasts three core capabilities: eMBB—enhanced Mobile Broadband; uRLLC—ultra-Reliable & Low Latency Communication; and mMTC—massive Machine Type Communication—designed to address three major application scenarios and build a fully connected world where everything is interconnected. Yet despite its many advantages, 5G, like all technologies, follows the law of unity of opposites: "No one is perfect," and 5G has its own troublesome shortcomings. First, there’s the issue of high costs. It’s widely known that operators face enormous cost pressures when building 5G networks. To put it simply, according to data collected by China Mobile, the cost of a single 5G base station is roughly 160,000 yuan. Based on publicly available forecasts estimating that the number of 5G base stations will be twice that of 4G, achieving the same coverage as 4G would require about 10 million base stations. Thus, the total investment required for procuring 5G base stations would reach an astronomical 1.6 trillion yuan. However, this figure represents only the cost of equipment procurement by telecom operators—it doesn’t include expenses such as electricity bills, maintenance fees, labor costs, site rental fees, and so forth once the network is up and running. Therefore, reducing network deployment costs through various innovative approaches has become a top priority for operators. For example, in terms of power supply and service transmission for base stations, traditional solutions involve operators using composite optical cables to bring in external grid power. Annually, the publicly announced projects for fiber-optic cable installation at base stations often run into tens of millions of fiber-kilometers. How can these costs be effectively reduced? Second, there’s the issue of network deployment efficiency. Aside from the exorbitant costs of fiber-optic cable procurement and labor-intensive maintenance, the construction of base stations often gets delayed due to excessively long lead times for introducing or upgrading external power supplies. For instance, one of 5G’s biggest selling points is its flexible deployment capability: with its high bandwidth, low latency, and massive connectivity, 5G can connect any IoT device anytime, anywhere. However, 5G base stations themselves are hard pressed to achieve truly flexible deployment anytime and anywhere. After all, a mobile communication base station isn’t just the base station equipment itself—it’s a complete structure comprising equipment rooms, power lines, steel towers, masts, and other components. Among these, power supply equipment plays a crucial role. In scenarios such as disaster relief, large-scale galas, or sporting events, how can we eliminate that “last mile” of cabling? Thus, exploring ways to speed up and enhance the flexibility of network deployment in different environments has become a critical issue that operators urgently need to address.

Can laser power supply also be implemented in 5G base stations?

The application of laser-based wireless power transfer technology to 5G base stations is still in the R&D phase and has a long way to go before it can be fully implemented. However, from the broader perspective of communication technology, extending “wireless power transfer” from smartphones to 5G base stations represents an important step in the evolution of power transmission. This development will carry significant implications—not only for ordinary users but also for telecom operators. Remember Xiaomi’s wireless charging technology unveiled earlier this year? Compared to today’s mainstream contact-based wireless charging solutions, this technology truly enables smartphones to “wirelessly harvest power” without physical contact. And recently, this “black-tech” innovation has been further expanded—now making it possible to power 5G base stations, marking a milestone in the history of 5G infrastructure development. On October 4, Ericsson announced a collaboration with laser innovation company PowerLight Technologies, successfully completing a proof-of-concept demonstration in Seattle. They showcased the world’s first secure 5G base station powered entirely wirelessly—a solution that uses optical beams—a laser-based technology that converts electricity into high-intensity light, which is then captured by the wireless base station and converted back into electrical energy, enabling remote power supply.
