What are the components of a base station?
The base station consists of four parts:
1. Antenna system
Generally, there are multiple antennas installed on the top of the base station, which are mainly responsible for the transmission and reception of signals, and are connected to the RRU.
2. RRU (Remote Radio Frequency Unit)
RRU can be divided into multiple sectors for the transmission of 2G, 3G, 4G and even 5G signals. Both signal generation and extraction of radio signals take place here.
3. BBU (Base Band Unit)
The BBU is placed in the equipment room and connected to the RRU through an optical fiber. It is the core of the base station and the unit that processes the original signal.
4. Physical support
It mainly includes power system, backup battery (to prevent power failure), transmission equipment, air conditioning system (to maintain the optimal temperature for normal operation), etc.
Based on the above components, they work together to form a base station for transmitting signals. Multiple base stations form a tightly connected network to provide users with seamless coverage of network services.

While there are many factors to consider when designing an overall system, terminal blocks are an optimal solution for complex electrical system connections. With a variety of color options and configurations, Premier Cable’ terminal blocks offer a range of options to meet your design challenges.
CAN-bus has been widely used in various automation control systems. For example, CAN-bus has incomparable advantages in various fields such as automotive electronics, automatic control, smart buildings, power systems, and security monitoring.
M12 encoding types are A encoding, B encoding, D encoding and X encoding. A-code, B-code and X-code are some of the earliest developed and longest-available M12 connectors. The latest M12 coding types currently under development are K coding for AC and L coding for PROFINET DC.
The three different sizes of NMEA 2000 certified DeviceNet standard cabling are "micro," "mid," and "mini."
The Premier Cable Starter Kits provide everything you need to get to create a basic NMEA 2000 network from scratch.
DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
