*RRU in Telecommunication* A Remote Radio Unit (RRU), also known as a Remote Radio Head (RRH) is a transceiver deployed on base stations. A transceiver combines the functionality of both a transmitter and receiver in one unit. Due to its features, RRU is used as a transceiver in telecommunications. *Definition of RRU* An RRU is a device that connects wireless devices with wireless networks to ensure the transmission and reception of data, including text messages, and various other forms of communication. In other words, it establishes a connection between an operator network with mobile devices, cell phones, or other users’ equipment (UE). The RRU is typically located close to the antenna, commonly on top of the base station. RRUs can amplify, filter, and receive and transmit RF signals. Additionally, the RRU unit establishes a connection to the base station through a bidirectional fiber optic link. A common public radio interface (CPRI) is this optical interface link. CPRI is an interface protocol developed by telecommunications equipment manufacturers, including Huawei, Cisco, Nokia, and many more. Note that the RRU helps to reduce losses in coaxial feed lines. This helps to improve the efficiency of the system and delivers a significant degree of flexibility in the construction of cellular sites. This makes it easier to upgrade to new equipment and devices. *Functions of RRU* The RRU in a BTS performs some key functions which may include the following: 1) Facilitates the transmission and reception of user signals to and from the base station. 2) Offers seamless support and connectivity for user equipment, including functions such as power management and signal delay. 3) Controls and processes electromagnetic signals received from the through via a hollow guide known as a Jumper. 4) Serves as an interface between two different physical links, such as optical and electromagnetic connections. 5) Manages and controls auxiliary equipment, such as the Remote-Control Unit (RCU), for tasks like remote electrical tilt adjustment (commonly referred to as RET). 6) Generates and transmits various signals, including but not limited to VSWR, RET, and ACT, among others. #telecommunications #RRU #RRH #CPRI #Jumper #wirelesscommunications

Digital tilts in Active Antenna Units (AAU) are a key feature in 5G networks, enabling dynamic beam control and optimization. What are Digital Tilts? Digital tilts, also known as Digital Beam Steering or Electronic Beam Tilt, allow for software-controlled adjustments to the antenna's radiation pattern. This is achieved through advanced signal processing and phase shifting techniques. How do Digital Tilts Work? 1. Phase Shifters: Digital tilts utilize phase shifters to adjust the phase of RF signals fed to individual antenna elements. 2. Beamforming: The adjusted phases create a phased array effect, steering the beam in desired directions. 3.

Reduced Interference: Minimize interference through precise beam control. 4. Increased Spectral Efficiency: Maximize spectrum utilization. 5. Simplified Maintenance: Remote software updates eliminate manual adjustments. Types of Digital Tilts: 1. Horizontal Digital Tilt (HDT): Adjusts beam direction horizontally. 2. Vertical Digital Tilt (VDT): Adjusts beam direction vertically. 3. 3D Digital Tilt: Combines HDT and VDT for precise beam control. Key Features: 1. Resolution: Digital tilt resolution defines the granularity of adjustments (e.g., 1°, 0.5°). 2. Range: Digital tilt range defines the maximum adjustment angle (e.g., ±30°). 3. Speed: Digital tilt adjustment speed affects how quickly the beam can be reconfigured. Vendors Offering Digital Tilt Solutions: 1. Ericsson 2. Huawei 3. Nokia 4. ZTE 5. CommScope 6.

LTE technology LTE (Long Term Evolution) is a wireless communication technology developed under the leadership of 3GPP. To be precise, LTE is not equal to 4G. It is a transition technology between 3G and 4G. We prefer to call it "quasi-4G" or "3.9G". There are two main LTE standards: TD-LTE (time division duplex) and LTE-FDD (frequency division duplex). If nothing unexpected happens, LTE will continue to evolve and become an important technology in 5G networks. Peak rate: 100Mbps downlink, 20Mbps uplink Delay   Control surface IDLE → ACTIVE: <100ms   User plane: one-way transmission <5ms   Mobility: 359 km/h Spectrum flexibility    1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz variable bandwidth    Supports global mainstream frequency bands and new frequency bands #LTE #TD-LTE #LTE-FDD
