Product Description:
The Ericsson 4428 B3 KRC 161 713/1 is a component related to Ericsson's mobile communication infrastructure, specifically designed for the Band 3 frequency range in mobile networks. It is an important part of the radio access network equipment, playing a role in signal transmission and reception for mobile communication services.
1. Technical Specifications
-
Frequency Band: Operating in Band 3, which typically has a frequency range around 1710 - 1880 MHz (uplink: 1710 - 1785 MHz; downlink: 1805 - 1880 MHz). This frequency band is widely used for LTE (Long Term Evolution) and other mobile communication technologies.
-
Radio Configuration: It is likely a multi - input multi - output (MIMO) device, often with a 4T4R (4 transmit and 4 receive antennas) configuration. This MIMO setup helps improve data throughput and link reliability by taking advantage of spatial multiplexing and diversity techniques.
-
Output Power: The device may have a specific output power rating, for example, it could be designed to provide a certain amount of power per antenna port to ensure sufficient coverage and signal strength within the network cell. The output power might be in the range that allows for effective communication over the desired distance and area.
-
Interface: It is equipped with appropriate interfaces for connecting to other network elements. These may include optical interfaces for high - speed data transfer to the baseband unit and electrical interfaces for power supply and control signals.
2. Physical Characteristics
-
Size and Form Factor: It is designed to be compact and suitable for installation in various environments, such as outdoor base stations or indoor distributed antenna systems. The size is optimized to fit standard mounting brackets and enclosures, making it easy to integrate into existing network setups.
-
Build Quality: Made with high - quality materials to withstand harsh environmental conditions, including temperature variations, humidity, and electromagnetic interference. It is likely to be ruggedized to ensure reliable operation over a long period.
3. Functionality
-
Signal Processing: Performs functions such as modulation, demodulation, and encoding/decoding of the radio signals in the Band 3 frequency range. It also participates in functions like beamforming in a MIMO system to direct the radio energy towards the intended users and improve the overall system performance.
-
Network Integration: Works in conjunction with other components of the mobile network, such as baseband units and core network elements, to enable seamless communication between mobile devices and the network. It helps in managing the radio resources efficiently and ensuring smooth handovers between different cells.
4. Applications
-
Mobile Network Deployment: Used in the deployment of LTE networks to provide high - speed data services to mobile users. It can also be part of 5G network rollouts, especially in areas where the Band 3 frequency is utilized for initial coverage and capacity enhancement.
-
Urban and Rural Coverage: Helps in providing coverage in both urban areas with high user density and rural areas where maintaining a reliable connection is crucial for communication and data access.
