5G New Radio (5G NR)

(The Golden Gate Bridge, San Francisco, California - Jeff M. Wang)


5G has three main focuses - mobile networking, IoT, and very high-performance industrial control - of which mobile networking will be the most important for most people over the next few years, and which is best thought of as a continuation of 4G's Long Term Evolution (LTE) under a new flag. 

A new generation of wireless needs a new generation of radio. 5G is the fifth generation of wireless technology and NR stands for a new radio interface and radio access technology for cellular networks - a physical connection method for radio based communication. Other kinds of radio access technologies include Bluetooth, Wi-Fi and 4G LTE. All cell phones use radio waves to facilitate communication as they convert your voice into digital signals. Internet data is sent and received via these radio waves, too.  

5G NR uses two frequency ranges: frequency range 1 (FR1) includes 6 Ghz frequency bands and below. Frequency band 2 (FR2) includes bands in the millimeter wavelength (or mmWave) range, which includes 20-60 Ghz. That mmWave range is particularly helpful to enable 5G Ultra Wideband (UWB). 5G NR will enable the network to support adaptive bandwidth. Key benefits of 5G NR will include more capacity for wireless users, improved links among users (so less lag time and network loss), and enhanced speed of data rates.

5G will deliver significantly faster and more responsive mobile broadband experiences, and extend mobile technology to connect and redefine a multitude of new industries. 5G network will extend the wireless connectivity beyond the people, to support the connectivity for everything that may benefit from being connected that might include everything from personal belongings, household appliances, to medical equipment, and everything in between. 5G network will enable emerging services that include remote monitoring and real-time control of a diverse range of smart devices, which will support machine-to-machine (M2M) services and Internet of Things (IoT), such as connected cars, connected homes, moving robots and sensors. 5G networks will deliver richer content in real time ensuring the safety and security that will make the wireless services more extensive in our everyday life. Some example of emerging services may include high resolution video streaming (4K), media rich social network services, augmented reality, and road safety.
