5G RRU Applications
C-RAN is a network technology for efficient communication with centralized information processing performed remotely within a cloud system. Signals are processed at remote locations, with base stations connected via efficient fiber optic connections. It is efficient and offers several advantages in terms of system implementation and maintenance.
A Remote Radio Unit (RRU) acts as a transceiver for a mobile device. RRUs are basically arrays of antennas arranged in different directions to cover a large area around a cell tower.
RRUs in C-RAN
Several 5G RRU use cases are detailed below:
1. Occupied bandwidth typically 100 MHz with one or more 5G TDD component carriers
2. Data converter on baseband SoC runs at 245.76 Msps, supports two TX and two RX IQ streams
3. Supports DPD in RU systems to meet power and performance requirements
4. Periodically observes multiple TX paths to track changes in temperature and environmental changes
Premier Cable is a leading company in telecommunication cables, including RRU power cable, RRU power connector, BBU/OLT power cable assemblies, CPRI Cable, coxial cable grounding kit....
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.
