What does CPRI mean?
What does CPRI mean?
Common Public Radio Interface
The Common Public Radio Interface (CPRI) standard defines an interface between Radio Equipment Control (REC) and Radio Equipment (RE). Oftentimes, CPRI links are used to carry data between cell sites and base stations.
What is CPRI 5g?
Common Public Radio Interface, better known as CPRI, is an interface standard developed more than tne years ago by network equipment manufacturers (NEMs), including Ericsson, Huawei, NEC, and Nokia. It is commonly used to carry data between 4G cell sites and base stations.
What is Fronthaul and backhaul in 5g?
Backhaul is a widely known term that describes the link between a baseband and the core network. Fronthaul, on the other hand, connects the baseband to a remote radio unit. This can simplify deployment by decreasing equipment footprint and improve network efficiency by allowing for centralized management of resources.
What is CPRI approved?
Set up in 1960 by the Government of India, it functions as a centre for applied research in electrical power engineering assisting the electrical industry in product development and quality assurance. CPRI also serves as an independent authority for testing and certification of power equipment.
What is CPRI approved panel?
Fabricated using the latest technology, these CPRI Approved Electric Control Panels are made from durable materials sourced from well known vendor in the industry. These CPRI Approved Electric Control Panels are very useful to synchronize, control and distribute electricity evenly.
What are the specifications of CPRI?
CPRI specifications support L1 in-band protocol, High level Data Link Control (HDLC) and Ethernet for configuration and management data. Other data types supported by CPRI include synchronization for frame and time alignments.
What is CPRI in a mobile network?
The CPRI (Common Public Radio Interface) is a popular standard to transport baseband I/Q signals to the radio unit in Base Station. It allows efficient as well as flexible I/Q data interface for various wireless standards such as GSM, WCDMA, LTE etc.
What bit rate options are available for CPRI?
The following are defined for CPRI: Note that generally bit rate options 1,2,3 are available over MMW, and 1,2 over FSO. These can be “aggregated” using 2+0 and higher (4+0, etc) links to provide higher capacities, for example where more LTE sectors are required.
What is the full form of CPRI?
CPRI is the short form of Common Public Radio Interface. CPRI is popular standard for transporting baseband I/Q signals to the radio unit in traditional BS (Base Station). CPRI allows efficient and flexible I/Q data interface for various standards e.g. GSM, WCDMA, LTE etc.
What is the frequency band of 4G LTE?
4G LTE Frequency Bands & Spectrum Allocations. LTE is designed to work across a number of frequency bands – E-UTRA operating bands- currently ranging from 450 MHz up to 3.8GHz. The available bandwidths are also flexible starting with 1.4 MHz up to 20 MHz with Carrier Aggregation allowing use of wider multiples.
