　　Introduction to Pico Base Station Antenna

　　In today's wireless communication field, indoor signal coverage and user traffic demand are growing day by day. Pico base station antenna has become a key device to solve this problem with its unique advantages. The following will introduce Pico base station antenna in detail.

　　Basic functions and positioning

　　The LTE fusion Pico base station system is a wireless broadband mobile communication product developed based on the 3GPP standard, and the Pico base station antenna, as an important part of the system, undertakes the key task of signal transmission and reception. As a wireless WiFi antenna and 5G enhanced antenna equipment, Shenglu Pico base station can provide the breadth and depth of LTE network coverage. It can not only provide signal blind spot compensation and enhancement services for macro base stations, so that areas with weak or no signals can obtain good coverage, but also share the user load of macro base stations, effectively reduce the pressure of macro base stations, and improve the overall network operation efficiency.

　　Significant features

　　Broadband/dual-band characteristics: It can meet the needs of 4G/5G fusion networking, can adapt to signal transmission of different network formats, and provide good compatibility for future network upgrades and evolutions.

　　Omnidirectional coverage capability: With excellent omnidirectional coverage capability and a roundness of <7dB, it can meet the needs of all-round indoor coverage and ensure that stable signals can be received in every corner of the room.

　　Low-profile design: Only 10 mm high including PCB, this slim design will not affect the beauty of the indoor environment after installation, and it is easy to integrate into various indoor scenes.

　　Easy to install: With POGPIN feeder, the installation process is extremely simple for end users. It only needs 3 screws to fix it, and there is no need to install connectors or weld feeders, which greatly reduces the installation difficulty and time cost.

　　Wide application scenarios

　　Pico base station antennas can be widely used in urban hot spots, supermarkets, stadiums and other crowded areas. These areas often have a large number of users and large data traffic, and have high requirements for network coverage quality and capacity. Pico base station antennas can meet these needs well. Especially in areas with high data traffic, high ARPU value users, significant tidal effects and LTE target construction areas, its advantages are more prominent.

　　Comparison with traditional solutions and principle analysis

　　Principle of traditional indoor coverage solution

　　The traditional indoor coverage solution adopts a multi-level architecture of BBU+RRU + combiner + repeater + external antenna. BBU (baseband processing unit) is responsible for baseband signal processing, RRU (radio remote unit) converts baseband signals into RF signals and transmits them to the combiner through the feeder, the combiner combines multiple signals and transmits them to the repeater, the repeater amplifies the signal and transmits it through the external antenna. This multi-level architecture has many links, the signal is prone to loss during transmission, and the connection between the devices is complex and the maintenance cost is high. At the same time, due to the use of external antennas, its coverage range and signal uniformity are subject to certain restrictions, making it difficult to achieve all-round high-quality indoor coverage.

　　Principle of Pico base station antenna related system architecture

　　The ampsite system architecture (such as Lampsite) adopts a three-level architecture of BBU + switch + PRRU. The BBU is also responsible for baseband signal processing, the switch is responsible for data exchange and transmission, and the PRRU (distributed micro base station radio frequency unit) integrates the radio frequency module and antenna function, which can directly transmit and receive signals. This architecture reduces the intermediate links, reduces signal transmission loss, and improves signal transmission efficiency. The PRRU is compact and can be flexibly deployed in various locations indoors. Combined with the omnidirectional coverage capability of the Pico base station antenna, it can achieve more uniform and better indoor coverage.

　　The reason why the Pico base station antenna can achieve efficient coverage is that its omnidirectional coverage characteristics can radiate the signal evenly in all directions, and the circularity <7dB ensures that the signal strength difference in different directions is small. At the same time, its broadband/dual-band characteristics enable it to process 4G and 5G signals at the same time, meeting the needs of converged networking. In terms of installation, the simple fixing method and the design without complex connections enable it to be deployed quickly, respond to temporary capacity needs in crowded areas in a timely manner, and adapt well to scenarios such as tidal effects.
