450MHz LTE Antennas

　　450MHz LTE Antennas are LTE antennas that work in the 450MHz frequency band. The following is a related introduction:

　　Features

　　Wide coverage: 450MHz belongs to the low frequency band, the signal wavelength is long, the diffraction ability is strong, and it is less affected by obstacles during the propagation process. It can achieve a longer transmission distance and provide good coverage in vast and complex terrain areas such as rural and mountainous areas2.

　　Strong penetration ability: The signal in this frequency band has a strong ability to penetrate obstacles such as walls and buildings, which can effectively improve the signal coverage in indoor and underground scenes. It is suitable for applications that need to communicate inside buildings or underground spaces, such as mines, underground parking lots, etc.

　　Relatively strong anti-interference ability: Compared with some high-frequency bands, the use of the 450MHz band is relatively less crowded, relatively less interfered, and the signal transmission is more stable, which can provide more reliable guarantee for communication2.

　　Limited data transmission bandwidth: Although it can meet basic data transmission needs, the available bandwidth of the 450MHz band is relatively narrow compared with high-frequency bands, and the theoretical data transmission rate is relatively low, which is not suitable for scenarios with extremely high requirements for high-speed data transmission.

　　Type

　　Directional antenna: Such as the 450MHz Yagi antenna, which usually has a higher gain and can focus the signal in a specific direction for transmission and reception, and can achieve a longer transmission distance and stronger signal strength in this direction. It is suitable for point-to-point or point-to-multipoint communication scenarios, such as signal transmission between two distant base stations2.

　　Omnidirectional antenna: Common indoor ceiling omnidirectional antennas can radiate and receive signals evenly in 360° in the horizontal direction, so that the device can receive a relatively uniform signal strength in all directions. It is suitable for places that require all-round coverage, such as in a relatively open indoor space or a small base station, to provide communication coverage for surrounding devices2.

　　Flat panel antenna: usually has high gain and good directivity, relatively small size, flat appearance, easy to install and hide, the installation angle can be adjusted as needed to achieve the best signal coverage, often used in scenes with high aesthetic requirements or strong signal coverage within a certain angle range.

　　Application

　　Smart grid: In the power system, it is used to connect smart meters, power terminal equipment, etc., to realize real-time collection, transmission and monitoring of power data, and support intelligent management and operation of the power grid, such as remote meter reading, power equipment status monitoring, etc.

　　Industrial automation: At the industrial production site, it can connect various industrial sensors, controllers, monitoring equipment, etc. to realize communication and data interaction between equipment, support industrial automation production and process control, and improve production efficiency and quality.

　　Transportation: Communication systems used in transportation fields such as railways and highways, such as train dispatching, vehicle monitoring, intelligent traffic signal control, etc., to ensure the safety and efficient operation of transportation.

　　Public safety: In public safety fields such as emergency communication, fire protection, and security, 450MHz LTE antennas can provide reliable communication guarantees, realize on-site command, data transmission, video monitoring and other functions, and help relevant departments quickly respond to and handle emergencies.
