This page is all about the new 5G Matlab projects with upcoming research challenges. The standard 5G networks are designed with the objective to reach maximum efficiency, data transfer rate, and minimum network delay in wireless communication. The massive MIMO technique is used in the larger beamforming antenna for reducing the radio propagation issues. Further, it also includes other challenges such as signal propagation, inadequate bandwidth, etc.
What Is 5G New Radio?
The New Radio (NR) is the embryonic RAN technology in the form of a radio interface to support the present cellular network, i.e., 5G communication. The UMTS, LTE, and GSM are considered as the forerunner of the current 5G NR. Initially, GSM (2G) is used for the voice; later, it is improved as UTMS (3G) and LTE (4G) to increase the system efficiency and data transfer rate.
Most importantly, 5G new radio majorly depends on the LTE network to meet the maximum efficiency and bit rate for mobile internet. But, now, the scope of the 5G NR is going beyond the cellular network expectancy. Overall, this network has the core demand to make ultra-fast wireless connections possible in all places. Further, the standard 5G NR is used in the following 3 case studies,
- Ultra-Reliable and Low Latency Communications (URLLC)
- It is well-suited for both machine and human-centric communication for achieving minimum delay and maximum accessibility and reliability.
- For instance: remote control systems, autonomous vehicles, 3D gaming, mission-critical systems, and more
- Massive Machine Type Communications (mMTC)
- It is mainly intended only for machine-centric systems to establish communication over a huge network of computing devices.
- Further, it is expected to reach a high battery life, high connectivity (dense), and low cost.
- Enhanced Mobile Broadband (eMBB)
- It is used for a human-centric system for more user density, capacity, and data rates. Also, it is expected to have a smooth user experience and dynamic motion in the case of a broad coverage.
