 5G

Mobile and internet connectivity are key to making so many of the things we value possible—remote work, keeping in touch with far-away loved ones, reliable access to the internet—and mobile connectivity demands are growing rapidly. Luckily, new 5G technologies are providing efficient ways to solve our connectivity issues. New wireless technologies, otherwise known as 5G new radio, provide radio-based communications and other radio access technologies such as WiFi, Bluetooth, 4G LTE, etc. With 5G new radio innovations, our communication system designs can function more efficiently—with higher speed, higher capacity, and lower latency.   

The Future of Communication Design Lies With 5G New Radio

If you want to truly create designs for the future, consider designing with 5G new radio technologies. 5G new radio is the newest radio interface that can meet all the present needs of mobile connectivity. 5G new radio enables 5G mobile communication technology to be more flexible, scalable, and efficient in its power and spectrum utilization. 5G new radio features adaptive bandwidth within two frequency ranges:

  1. The frequency range 1 of 5G new radio is up to 6GHz and below. 

  2. The frequency range 2 of 5G new radio is within 20-60GHz. It includes the millimeter frequency range, which is important in enabling 5G ultra-wideband (UWB)

Design Goals of 5G New Radio

There are three design goals for 5G new radio designs:

  1. Increase mobile broadband - 5G new radio utilizes higher spectrum waves (typically millimeter waves) and broader bandwidth, making it more suitable than LTE for future mobile communication designs. Along with mobile broadband speed in gigabits, 5G new radio offers lower latency, higher bandwidth, and greater connectivity. Mobile broadband with 5G new radio enabling technologies are used in dense areas and are useful in high user mobility services.

  2. Enable seamless machine-to-machine communication - To enable machine-to-machine communication, a mobile network capable of handling billions of nodes is required. The network should also have the capacity to handle machine-to-machine communications in conjunction with human-based communications. There should not be any delay caused by the inability of the network to handle different communication patterns. The wide bandwidth and hyper-connectivity of 5G new radio makes it the best candidate for seamless machine-to-machine communication. 

  3. Ensure reliable, low latency communication networks - Due to properties such as high speed, broad frequency spectrum, and greater connectivity, the International Telecommunication Union (ITU) has classified 5G communications into enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low latency communications (URLLC). The reliability of 5G new radio is unmatched compared with conventional LTE services, making it applicable in diverse and intense traffic services. 

5G new radio designs that incorporate these goals are the best types of technology to ensure high data transfer rates, low latency, and increased capacity. Let’s take a closer look at these advantages.

Advantages of 5G New Radio Technologies

Increased Capacity 

For a given amount of space, 5G technology offers wireless customers more connected device capacity. Compared to 4G, the 5G new radio capacity is around 1000 times that, making it the best technology for IoT applications. The limitation on connected devices to a network is eliminated with the introduction of 5G new radio, which enables seamless communication with thousands of devices. In densely populated cities with more than a million devices in every square kilometer (such as smartphones, smartwatches, other wearables, smart locks, vehicles, etc.), 5G technology is beneficial. 

High Speed

In terms of speed, 5G technology is far faster than 4G technology. The utilization of millimeter waves as well as the broader bands of the frequency spectrum increases the speed of 5G communication compared to 4G. 5G wireless connectivity has an expected speed of 10Gbps, which is 100x that of 4G technology. Considering this high speed, 5G technology is clearly the future of fast broadband connections. 

Low Latency 

Latency is the measure of the time taken by a signal to travel from the transmitter to the receiver and back. In terms of redundancy, 5G networks offer the lowest round-trip data transmission time. 

Low latency becomes a significant requirement when choosing communication technology for mission-critical systems and autonomous driving applications. The latency of a 5G network is less than a millisecond, which makes it suitable for such applications. 

Applications of 5G New Radio Technologies

5G communication is used in a wide array of domains such as education, entertainment, smart homes, healthcare, logistics, communications, etc. The efficient, simultaneous transfer of voice and high-speed data is one of the remarkable features of 5G technology that has revolutionized cellular communication.

Another important application of 5G new radio technologies is in IoT and artificial intelligence applications where mostly mMTC services are employed. IoT and artificial intelligence-enabled devices rely on 5G and other wireless technologies such as ZigBee, WiFi, Bluetooth, cellular technologies (GSM, LTE),  etc. However, advantages such as the capacity to accommodate more devices, a diverse range of speed, broader bandwidth, and the quality of service make 5G technologies popular for IoT applications. The low redundancy property of 5G communication enables remote control access of IoT-based devices. 

5G New Radio: Designing for the Future

5G new radio is truly the future of communication systems. This technology helps physically realize virtual and augmented reality applications with merits such as high speed, seamless signal transmission, low lag time, and low network losses.
