As per 3GPP, The gNB is divided into two logical functions: the CU and DU. The DU is the baseband unit in a 5G RAN. It handles layer 1 and […]
3GPP Architecture for 5G NR
5G 3GPP Releases from Release 15 to Release 18
5G is an evolving standard. The initial version of 5G was accomplished with the freezing of Release 15 late-drop in summer 2019. Enhanced features originally were introduced in Release 15 […]
Why Is 5G Growth Faster Than The Previous Generations?
5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. 5G has more capacity than 4G. 5G is […]
3GPP Yang Model for nrCellDU “5G SW Development”
3GPP TS 28.541 explains how Yang models are implemented in 5G gNB in gNB-CU and gNB-DU as below: The nrCellDU table models a geographical area of radio coverage that is implemented […]
How 5G Drives Technical Efficiency Gains
5G builds upon existing network infrastructure to handle the increased demand for data in an interconnected society. It is transforming industries and is changing the way businesses and consumers use […]
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 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 […]
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 […]
Voice Service in 5G Network (VoNR, EPSFB)
Although the request for data services is the primary driver behind the growth and evolution of 5G, voice service is still an indispensable part of mobile communication network. The Voice […]
