5G NR (new radio) is the new standard for 5G wireless technology, which is capable of much faster, more efficient, and more scalable networks. 5G NR technology will enable us to connect with many things in the surroundings with low latency and lightning speed.
Since the third generation of mobile networks has been launched, we can send and receive data via mobile networks. Current 4G technology offers a faster data rate than its previous generations, but it has limitations due to its bandwidth, scalability, and number of users under individual cells.
5G NR has been designed to scale the network efficiently for the next 10 to 15 years. Any future enhancements will not affect the existing network, and performance improvements are possible.
5G NR – Roadmap
We are expecting the initial 5G NR system to be launched in the middle of 2018 or the beginning of 2019. However, many tests have to be conducted, and spectrum allocation and infrastructure, including user equipment (UE), have to be developed within a limited time frame.
How is 5G NR work and high performance achieved?
Unlicensed spectrum: 5G NR will use a millimeter wave spectrum above the 24 GHz range. Some of the candidates for 5G NR are
Below 1 GHz bands like 600 MHz and 700 MHz for long-range transmission
Mid 1GHz to 6 GHz unlicensed bands for higher bandwidth
Millimeter wave: it plays a big role in the 5G NR system due to its much higher bandwidth. Top candidates for future 5G networks are 24.25 to 27.5 GHz, 27.5 to 29.5 GHz, 37 GHz, 39 GHz, and 57 to 71 GHz range.
Massive MIMO: using MIMO technology, a downlink speed of up to 952 Mbps can be achieved in test cases. MIMO will use complex antenna arrays to multiply transmission speed to achieve maximum speed and efficiency.
Small Cell: a small cell network is a group of low-power transmitting base stations that uses millimeter waves to enhance network capacity. The total network load is shared between small cells, and difficulties of physical obstructions are eliminated.
Modern network terminologies like beamforming and full duplex can be efficiently utilized with small cell concepts and millimeter waves for transmission.
Dynamic TDD technology: allows simultaneous transmitting and receiving efficiently and utilizes wider bandwidth for transmission. Advanced modulation techniques of existing FDD, TDD, and combined technology can be used for more efficient spectrum usage.
Self-contained TDD subframe structure offers much more efficient transmission capabilities and coexistence with other systems that the system supports.
Advantages of 5G NR
5G NR system will offer a much faster, scalable, and efficient network that can support billions of devices and emerging technologies like the Internet of Things. Moreover, unlicensed spectrum has unlimited opportunities due to higher bandwidth, even up to 500MHz.
One of the most important advantages of the 5G NR system is its forward compatibility for the next 10 to 15 years. 5G NR is capable of further enhancements in the coming years without interrupting the existing network.
Low latency design offers a much more reliable network and supports mission-critical applications with higher accuracy. Low latency and precision is very crucial in autonomous driving and the connected car concept.
