To identify the ideal Industrial Router for your application we have developed the Router Selector Tool which is a configurable filter to narrow down the results to match your exact requirements.
5G NR 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.
5G NR is designed to support fibre-equivalent bandwidth transmissions required for data demanding applications like streaming video, as well as low-bandwidth transmissions used in machine-to-machine communications at increased capacity where needed.
5G NR will also support transmissions with extremely low latency requirements – for example applied to vehicle-to-vehicle and vehicle-to-infrastructure communications which is a vital prerequisite in those settings
Like its predecessors, the 5G NR standard was created by the 3rd Generation Partnership Project (3GPP). The first iteration of 5G NR appeared in 3GPP Release 15.
The 5G NR standard supports a number of low-, mid- and high-frequency bands.
Frequency range 1, which includes frequency bands that are less than 6 gigahertz;
Frequency range 2, which includes bands with a low range combined with a high bandwidth and mmWave.
5G NR uses frequency bands in two frequency ranges:
Frequency Range 1 (FR1), for bands within 410 MHz – 7125 MHz
Frequency Range 2 (FR2), for bands within 24250 MHz – 52600 MHz
Benefits of 5G NR
In a growing connected world, 5G will certainly play a major role in industries and society including more capacity for wireless users, improved data rates and more importantly low lag and latency.
5G NR deployment modes
As 5G NR is being rolled out there are currently 2 Deployment Modes that are implemented. The two modes depends on several factors, including the existing infrastructure.
Essentially, a “Hybrid” as some of the 4G LTE infrastructure stays in place, while the radio frequency side of 5G NR presents the beneficial characteristics. Advantages are a more speedier rollout as current 4G facilities are reused. Non-Standalone 5G NR will provide increased data-bandwidth by using two new radio frequency ranges:
Frequency Range 1 (450 MHz to 6000 MHz) – This band overlaps with 4G LTE frequencies and is called as sub-6 GHz. Bands are numbered from 1 to 255.
Frequency Range 2 (24 GHz to 52 GHz) – This is the mm-Wave frequency band. Bands are numbered from 257 to 511.
For standalone mode, the full 5G NR technical standard is deployed. No residual 4G technical underpinnings are involved. For example, refers to using 5G cells for both signalling and information transfer. It includes the new 5G Packet Core architecture instead of relying on the 4G Evolved Packet Core to allow the deployment of 5G without the LTE network. It is expected to have lower cost, better efficiency, and to assist development of new use cases. However, initial deployment might see slower speeds than existing network due to the allocation of spectrum.
Network Slicing is also a key feature to the 5G network. 5G network slicing will allow MVNO and operators to use a portion of the 5G network spectrum to split and serve various use-cases, including mobile networking, smart homes, IoT, and inventory management. This enables service providers to tailor packages to customers needs for example for “Mission Critical” objectives like remote surgery for the medical industry.
5G network slicing supports enhanced mobile broadband (eMBB), which aims at maximizing the network speeds and data rates while having an acceptable QoS, including reliability and packet-error rates. This portion of the “Slice” will most certainly benefit data demanding applications.
There are three main primary use cases within the 5G NR
Enhanced Mobile Broadband (eMBB): Bandwidth-driven use cases needing high data rates across a mobile wide coverage area. For example 4K Media, AR and VR applications.
Ultra-Reliable Low Latency Communications (URLLC): Lowest possible latency and high network reliability for critical applications like autonomous vehicle, remote surgery/healthcare, or time-critical factory automation (e.g. semiconductor fabrication).
Massive Machine Type Communications (mMTC): Providing connectivity to a large number of devices that transmit intermittently a small amount of traffic such as Smart factories that presents this ideal scenario that will produce high productivity and efficiency.
The future of 5G NR is certainly exciting as this 5th generation of cellular technology is constantly evolving and dynamic that promises ground-breaking new capabilities and to unlock the potential of technologies such as Artificial Intelligence (AI), Extended Reality (XR) and the Internet of Things (IoT).
With the traits of low latency, increased spectrum and throughput. 5G technology is truly a key enabler of new B2B opportunities and create new emerging markets.
