1. Definition of RRU
RRU (Remote Radio Unit) is a new type of base station equipment used for wireless coverage and signal amplification in wireless communication systems. RRU is essentially a small wireless signal connector, and multiple RRUs can be connected together to form the same wireless signal distribution system. Compared with traditional base station equipment, RRU occupies a small area and has lower power. Therefore, RRU can be placed in more flexible and smaller places for installation, such as telephone poles, rooftops, etc.
2. Application scenarios of RRU
what is Rru
RRU is mainly used in the construction and maintenance of base stations in the field of mobile communications. Currently, RRU is mainly used in the following aspects:
1. Macro station construction: RRU can be used for macro station construction in mobile networks, with a wide coverage area, which can meet the large-scale coverage of wireless communication systems.
2. Indoor distribution system: RRU can be used in combination with DAS (Distributed Antenna System) to provide better wireless coverage in indoor construction.
3. Progressive network evolution of telecom operators: RRU plays an important role in the network evolution process of telecom operators and can improve the rate and reliability of data transmission.
3. Advantages and Disadvantages of RRU
As a new type of base station equipment, RRU has the following advantages:
1. Small footprint: Traditional base station equipment often requires a larger footprint, but RRUs are small and lightweight, and can be deployed more flexibly, thereby achieving a more reasonable distribution of base stations.
2. Low power: Traditional base station equipment has high power and needs to consume high power. In contrast, the RRU can communicate through the Internet and reduce the power of the modem, so as to achieve a certain energy saving effect.
3. Wide coverage: Because the RRU can communicate with other base station equipment, a larger wireless network can be formed that can cover a wide area.
However, RRU also has the following shortcomings:
1. Large signal loss: Although the RRU can provide a wide coverage of wireless signals, due to its small size, the signal strength is often weaker than that of traditional base station equipment, so there is a certain signal loss problem.
2. Poor security: The network connected to the RRU may face unexpected attacks, which brings certain security risks.
4. Summary
As an important part of the next-generation mobile communication field, RRU has many advantages such as small footprint, low power, and wide coverage, and can meet the wide-area coverage and signal amplification requirements of wireless communication systems. With the continuous development of technology, RRU will also continue to improve and develop, injecting more vitality into the development of the mobile communication industry.
