5G and Beyond Mobile Wireless Technology

(United Nations, Geneva, Switzerland - Alvin Wei-Cheng Wong)


Mobile revolution has changed everything. The next generation of wireless networks, the ‘fifth generation’ or 5G of which is seen as consumer oriented, will change the way we communicate, the way we do business, the way we do everything! The impact of 5G will extend well beyond telecommunications: by connecting people, machines and things on a massive scale. 5G networks will combine numerous wireless technologies, such as 4G LTE, Wi-Fi, and millimeter wave technology to push mobile connection speeds over 100 megabits per second. 5G will also leverages cloud infrastructure, intelligent edge services and virtualized network core. 

Instead of point-to-point communications provided by legacy mobile networks, 5G will move packets of data following the most efficient path to their destination. This shift enables real time aggregation and analysis of data, moving wireless technology from communication to computing. Four factors distinguish 5G from its predecessors: connected devices, fast and intelligent networks, back-end services and extremely low latency. These qualities enable a fully connected and interactive world with a variety of applications. 

5G wireless technology will provide the backbone for IoT (e.g., Health IoT) that greatly improves data transfer speeds and processing power over its predecessors. This combination of speed and computing power will enable new applications for mobile technologies, especially in health care. By 2020, the 5G network will support more than 20 billion connected devices, 212 billion connected sensors and enable access to 44 zettabytes of data gathered from a wide range of devices from smartphones to remote monitoring devices. Healthcare organizations are eager to embrace IoT devices because they save money by keeping patients out of the hospital. If IoT devices can diagnose people in advance then that saves huge costs. 

While 4G wireless mobile technology revolutionized the consumer market, 5G is set to transform the industrial space.



5G New Radio (NR)


It’s official: 5G New Radio standard is ratified by 3GPP. In a milestone that ushers in the next generation of wireless technology, the Third Generation Partnership Project has officially ratified the first release of the 5G New Radio standard in early December, 2017, with further updates through 2018. The non-standalone 5G NR specification, or NSA 5G NR, will rely on an operator having an LTE network in which to anchor its 5G NR carriers for boosting throughput speeds and cut network latency. 

[Qualcomm]: 5G NR will redefine everything. Our 5G development efforts are focused on creating a 5G network that takes on a much larger role than previous cellular generations—connecting new industries, enabling new services and empowering new user experiences. At the foundation of this next generation cellular network is 5G New Radio (NR), the global 5G standard for a new OFDM-based air interface designed to support the wide variation of 5G device-types, services, deployments and spectrum.


What is 5G?

[IEEE SPECTRUM]: Over the last several years, researchers have been hard at work exploring new concepts and technologies to answer the question “What is 5G?”.

The 3GPP, 3rd Generation Partnership Project, is the standards body that publishes agreed upon specifications that define our wireless communications standards.  They have outlined a timeline for 5G, and the first phase of definition for 5G, called New Radio or NR, just passed in early December 2017, with further updates through 2018.
Although NR Phase 1 will be different from the LTE protocol commonly used in today’s mobile communications, there will be similarities as well. The most stark differences between LTE and NR is the carrier bandwidth and operating frequency. In addtition, NR adds new beamforming capabilities – both in the analog and digital domains....
