5G NR (new radio) is the new standard for 5G wireless technology capable of much faster, efficient and scalable network. 5G NR technology will enable us to connect with many things in the surrounding with low latency and lighting speed.
Since the third generation of mobile network has been launched, we are able to send and receive data via mobile network. Current 4G technology offers faster data rate than its previous generations but it has limitation due to its bandwidth, scalability and number of users under individual cells.
5G NR has been designed to scale the network efficiently for next 10 to 15 years. Any future enhancements will not affect existing network and performance improvements are possible.
5G NR – Roadmap
We are expecting initial 5G NR system to be launched in the mid of 2018 or beginning of 2019. However, many tests have to be conducted, spectrum allocation and infrastructure has to be developed including user equipment (UE) within limited time frame.
How 5G NR works and high performance achieved?
Unlicensed spectrum: 5G NR will be using millimeter wave spectrum above 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 5G NR system due to 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, downlink speed 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: small cell network is a group of low power transmitting base stations which uses millimeter waves to enhance network capacity. The total network load is shared between small cells and difficulties of physical obstructions eliminated.
Modern network terminologies like beamforming and full duplex can be efficiently utilized with small cell concept and millimeter waves for transmission.
Dynamic TDD technology: allows to simultaneously transmitting and receiving efficiently and utilizing 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 efficient transmission capabilities and coexistence with other systems which the system supports.

To me if no one buys a 5G device the more the supply group PAYS?, because you are using the actual device to transmit the WAVE?
