Our last article panned across the applications and potential of 5G network. Discussing further about 5G and how it’s different from 4G. So let me confirm at first 5G determines not just the future of Internet but will help in the technologies and buzz word like IoT, IIoT, Industry 4.0, Cloud and what not to define digital transformation. 5G technology is expected to officially launch across the world by 2020, with testbeds in the US, China, South Korea and UK already live. Few say in the generation of content, 5G will be a saviour. Ericsson one of the major players in this domain, states, Being able to download a full-length HD movie in seconds and share your wow-moments with friends – that’s just the beginning. The true value of 5G is the opportunity it presents for people, business and the world at large: industries, regions, towns and cities that are more connected, smarter and more sustainable. It’s allowing industries to reinvent themselves. It affects you. And it’s starting now. Researchers found the top drivers for 5G include smart cities (60%), industrial automation and smart manufacturing (48%), high-speed connectivity (39%), fixed wireless (37%), and connected vehicles (35%).
With all leading mobile phone companies are on the edge of rolling out 5G mobile and wherein few mobile manufacturers already has, certainly 5G mobile is the next wave in the digital age. Sixty-seven percent of mobile providers will deploy their first commercial 5G networks within 18 months, another 21% within the next two years. Most (94%) expect increases in network traffic growth, connected devices, and mission-critical IoT use cases to drive security and reliability concerns. A majority (79%) say 5G is a factor in current security investments. But this would not stop 5G Mobile from entering into the market. Whether, there are intial glitches or maybe mere security concerns, 5G mobile innovators are giving every bit to make a faster mass rollout.
5G netwroks and the way it works is critically different and the architectures will be more pettifogging. When compared with 4G(LTE), 5G networks will operate in a high-frequency band of the wireless spectrum, between 28 GHz and 60 GHz. This range is known as the millimeter wave (mmWave) spectrum. The sub-6 GHz range that LTE calls home will also be used. 5G is expected to add unlicensed frequencies such as the 3.5 GHz to its list of new frequencies for mobile use. This means a lot of bandwidth will be available to users. 5G networks will have a dense, distributed network of base stations in the small cell infrastructure. 5G could end up being 100 times faster than its predecessor, with data speeds reaching 10 gigabits per second. That would allow consumers to download a full-length high-definition movie in seconds. It will be important that 5G networks support the coexistence of multiple standards (LTE, WiFi) and coordinate with various site types (macro, micro, and pico base stations). A premier challenge of 5G network design has been to create a network architecture capable of supporting this kind of flexibility while meeting the multifaceted access demands of an Internet of Things (IoT) future.
Noted earlier, unlike other generations of network 5G technology will be afar. The architecture and development process of 5G technology is disruptive in the history of networks. 5G technology provides wireless connectivity for far more connections than today’s networks. 5g technology is crucial as new types of connected objects are served by wireless networks. Imagine ‘Find My Phone’ functionalities. National instruments foresee, 5G technology for a rich, reliable, and hyperconnected world. But from new bands to wider bandwidth and new beamforming technology, 5G New Radio (NR) presents significant design, prototype, and test challenges. Unlike 4G, which requires large, high-power cell towers to radiate signals over longer distances, 5G technology or say wireless signals will be transmitted via large numbers of small cell stations located in places like light poles or building roofs. 5G technology and network operators can use spectrum they already own to build out their new networks. Though, few experts reckon that current status of 5G technology for cellular systems is very much in the early development stages.
5G Wireless Technology
To all the buzz about5G Wireless Technology seems promising. But 5G Wireless Technology also keeps the potential to augment the next generation of wireless technology. The new 5G wireless technology is not just the next version of mobile communications, evolving from 1G to 2G, 3G, 4G and now 5G. Given with solemn standardization bodies currently, 5G wireless technology are pushing, and often redefining, the boundaries of wireless technologies. These system-level inventions in 5G wireless technologies are driving the global 5G standard through our fundamental contributions to 3GPP. Many of the technologies to be used for 5G will start to appear in the systems used for 4G and then as the new 5G cellular system starts to formulate in a more concrete manner, they will be incorporated into the new 5G cellular system.
As reported by electronics notes; work moves forwards in the standards bodies the over-riding specifications for the mobile communications system have been defined by the ITU as part of IMT2020.
The currently agreed standards for 5G are summarised below:
|SUGGESTED 5G WIRELESS PERFORMANCE|
|Peak data rate||At least 20Gbps downlink and 10Gbps uplink per mobile base station. This represents a 20 fold increase on the downlink over LTE.|
|5G connection density||At least 1 million connected devices per square kilometre (to enable IoT support).|
|5G mobility||0km/h to “500km/h high speed vehicular” access.|
|5G energy efficiency||The 5G spec calls for radio interfaces that are energy efficient when under load, but also drop into a low energy mode quickly when not in use.|
|5G spectral efficiency||30bits/Hz downlink and 15 bits/Hz uplink. This assumes 8×4 MIMO (8 spatial layers down, 4 spatial layers up).|
|5G real-world data rate||The spec “only” calls for a per-user download speed of 100Mbps and upload speed of 50Mbps.|
|5G latency||Under ideal circumstances, 5G networks should offer users a maximum latency of just 4ms (compared to 20ms for LTE).|
