　　700 MHz 5G NR small base station antenna: the key force to create 5G deep coverage

　　As 5G networks move towards "ubiquitous connectivity, ultimate performance", the depth and breadth of signal coverage have become core challenges. With its unique frequency band advantages and compact and flexible design, 700 MHz 5G NR small base station antennas have become key equipment to fill coverage blind spots and increase network capacity, providing efficient 5G signal solutions for scenarios such as densely populated urban areas and remote areas.

　　1. Core advantages: big energy in a small volume

　　The coverage magic of the 700 MHz low frequency band: 700 MHz belongs to the low-frequency part of the Sub-6 GHz frequency band, with a longer electromagnetic wave wavelength, and particularly outstanding diffraction and penetration capabilities. Compared with high-frequency band antennas, it can easily penetrate obstacles such as walls and trees, achieve "building-around coverage" between urban buildings, and achieve "long-distance transmission" in suburban wilderness. At the same power, its coverage range is 2-3 times that of a 3.5 GHz antenna, and the coverage radius of a single station can reach 300-500 meters, which greatly reduces the number of small base stations deployed and reduces the cost of network construction.

　　Technical optimization for 5G NR: The antenna has been specially optimized for the characteristics of 5G NR (new air interface) technology. It supports Massive MIMO (massive multiple input multiple output) technology under the NR frequency band. Through the multi-antenna port design, it can transmit multiple data streams simultaneously and achieve a peak rate of more than 100 Mbps in the 700 MHz frequency band. At the same time, it is compatible with SA (standalone networking) and NSA (non-standalone networking) modes, and can seamlessly access the existing 5G core network, providing smooth transition capabilities for network upgrades.

　　Small and flexible deployment advantages: As a small base station antenna, its design pays great attention to lightweight and miniaturization. The antenna size is usually controlled within 30cm×20cm×10cm, and the weight is less than 2kg. It can be flexibly installed in small spaces such as street lamp poles, building walls, and signal towers. The installation method supports various forms such as pole-mounted and wall-mounted. No large-scale civil construction is required. The deployment time of a single station can be shortened to within 1 hour, which greatly improves the efficiency of network construction. It is especially suitable for rapid blind spots in urban hot spots.

　　Anti-interference and environmental adaptability: There is a complex electromagnetic environment with multi-band signals intertwined in the urban environment. The antenna can effectively suppress the interference of adjacent frequency signals such as 4G LTE and WiFi through a built-in high-performance filter to ensure the purity of 5G NR signals. The shell is made of flame-retardant ABS material, with IP65 dust and water resistance, and can work stably in the temperature range of -40℃ to +70℃. Whether it is hot and hot or rainy and snowy, it can maintain stable signal transmission performance.

　　2. Scenario landing: Accurate coverage of every corner

　　Blind spots in densely populated urban areas: In the city center with tall buildings, the macro base station signal is easily blocked by buildings, forming a coverage blind spot. 700 MHz 5G NR small base station antennas can be deployed in residential corridors, shopping mall mezzanines, underground garages and other areas, using their strong penetration capabilities to provide stable 5G signals for indoor users. For example, in large shopping malls, by deploying this antenna at the elevator entrances on each floor, the problem of weak signals in elevators and underground parking lots can be completely solved, allowing consumers to enjoy high-speed 5G networks throughout the shopping process.

　　Suburban and rural coverage: In areas such as suburbs and towns where macro base station coverage is weak, the low-frequency band advantages of this antenna can be fully utilized. By deploying small base stations around public facilities such as village committees, schools, and health centers, a 5G network covering the entire village can be quickly built. Villagers can enjoy high-definition video calls, online education and other services at home, and agricultural cooperatives can also use 5G networks to realize data backhaul of farmland IoT devices, helping rural digital construction.

　　Transportation hub enhancement: Transportation hubs such as railway stations, bus stations, and subway stations have large passenger flow, concentrated signal demand, and a large number of metal structures that block signals. Deploying 700 MHz small base station antennas in these areas can specifically enhance the signal strength of platforms, waiting halls, and underground passages. For example, on subway platforms, by installing this antenna on columns, it can effectively offset the electromagnetic interference when the train passes, ensuring that passengers maintain an uninterrupted 5G connection while waiting and riding.

　　Industrial park private network: Buildings such as factories and warehouses in industrial parks have extremely high requirements for signal stability and need to support real-time communication of industrial IoT devices. This antenna can cooperate with enterprise private network small base stations to provide low-latency, highly reliable 5G connections for production line equipment, AGV robots, environmental monitoring sensors, etc. In automobile manufacturing workshops, seamless coverage is achieved by deploying multiple sets of antennas to ensure real-time transmission of control instructions for welding robots and assembly robotic arms, thereby improving production efficiency.

　　3. Future Value: The "capillaries" of 5G networks

　　As 5G applications penetrate from the consumer end to the industrial end and government affairs end, the requirements for refined network coverage are getting higher and higher. As the "capillaries" of the 5G network, the 700 MHz 5G NR small base station antenna will play a core role in the networking mode of "macro station wide coverage + small station deep coverage".

　　It not only solves the signal coverage problem of the "last mile", but also accelerates the full popularization of 5G networks with low-cost and high-efficiency deployment. Choosing a 700 MHz 5G NR small base station antenna means providing "ubiquitous, on-call" 5G connection for every user and every device, making 5G truly a digital foundation that empowers thousands of industries.
