Open RAN disaggregates the RAN into main 3 components as below: ? Upper Layer Split Central Unit (CU) • Logical node that includes a portion of the eNB/gNB functions as defined […]
What the Open RAN Main Components?
Everything You Have To Know About PTP or Precision Time Protocol?
Introduction Several time synchronization mechanisms can be used in a network. The most common standards are Network Time Protocol (NTP) and Precision Time Protocol (PTP). NTP, which is the older, […]
What are C/U/M/S Fronthaul (FH) Planes in ORAN ?
O-RAN’s proposed concepts and architectures use a split-RAN concept. There are 8 known ways to functionally split the RAN, and each one proposes splitting the processing so that different parts […]
Open RAN Interoperability Between Multi-Vendor!
For the introduction of RAN functions disaggregation and open interfaces in 5G, 3GPP has in Release 15 specified a Higher Layer Split (HLS) option of the gNB, which is also […]
Why Do We Need to Change the RAN Mindset?
First, We need to understand the most important question, Why do we need to change our RAN from a traditional setup to a more flexible one? The Answer is: Heavy […]
Why 7.2x split is the Best Split Option?
O-RAN’s proposed concepts and architectures use a split-RAN concept. There are eight known ways to functionally split the RAN, and each one proposes splitting the processing so that different parts […]
Why is C-Band Spectrum Important for 5G?
Not all radio spectrums are equal. Sub 1GHz offers the best coverage profile; however, the amount of low band spectrum available is limited. Frequency range two (FR2), i.e. greater than […]
Summary of the 5G Interfering with Aviation Safety in the US
Federal Communications Commission FCC auctioned the C-band spectrum between 3.7-3.98 GHz in early 2021. The U.S. Federal Aviation Administration (FAA) has warned that the new 5G technology could interfere with […]
Functional Decomposition of the 5G RAN “Split Architecture”
In the high-level network architecture, the RAN is represented as a single functional entity whereas in reality the realization of a 5G RAN is not so straightforward. In GSM/GPRS and […]
The Road to Open RAN
The Road to Open RAN is not easy one, there are a series of steps should be taken before migration or starting design the network architecture based on Open RAN. […]
Four Satellite “Sweet Spots” in the 5G Ecosystem
For mobile operators, 5G is far more than a faster version of the 4G/LTE standard. 5G will be an entirely new networking architecture — “a network of networks” — with […]
