What is 5G Wireless Internet? Why is it Better than any other Wireless System?
5G Wireless Internet Technology or the 5th Generation Wireless System, condensed 5G, are the intended next generation wireless system which smartness would go beyond the current 4G standards.
All the undergoing researches on 5G aims higher capacity, lower latency, lower battery consumption than previous versions, to implement the better Internet connectivity that allows users a higher density of mobile broadband, and allowing massive machine communication with ultra-reliable facilities.
What would be the characteristics of 5G System?
The data rate goes up to tens of Mbps for over hundred thousand users and riches 100 Mbps in metropolitan areas.
If we talk about offices, it would reach up to 1 Gbps for many employees, and also facilitates connecting hundreds of thousands of wireless sensor simultaneously.
The Bandwidth efficiency needs to be extremely enhanced than 4G, and the coverage range would be improved as well.
Signaling efficiency should be enhanced, on the other hand, the latency should be reduced.
Some Real-world Steps of 5G
The 5G wireless facilities are undergoing the process and among the major projects of top telecommunication companies whose aim is to provide 5G facilities within 2020 to mobile users.
However, some companies have already shown us some hint which shows that we can have 5G technology sooner than expected.
America’s top telecommunication company, AT&T is planning to test 5G Technology in Austin, Texas, to connect residence with rapid wireless broadband links within 2017.
South Korean telecommunication companies are being ambitions to provide a facility of 5G technology in mobile phones until the Winter Olympics, 2018 in South Korea, where carrier Korean Telecom (KT) has strongly concerned to stable its place as the previous adopter of latest network technology.
Nokia also has plans to launch pre-standard 5G system in 2017 for home broadband trials. However, it will commercially be launched in 2020 after the final standard.
Superiority of 5G to other Wireless System
1G was Analog cellular. 2G technologies were the first generation of Digital cellulars such as GSM, CDMA, and TDMA. 3G technologies, like HSPA, EVDO, and UMTS, obtain speeds from 200 Kbps to few Mbps. 4G technologies, like LTE and WiMAX, are far smarter than previous wireless technologies with the speed of hundreds of Mbps and even Gbps.
5G Technology will use encoding known as OFDM, that’s the same encoding uses by LTE, its air interface would be designed with lower latency-compatible and broader flexibility over LTE, though.
4G technologies are mostly focused on obtaining raw bandwidth, although 5G is designing to provide pervasive connectivity for prompt and resilient connection to the user.
5G Internet system would be designed to maintain different functions such as augmented reality, loT (Internet of Things), connected wearables, and immersive gaming.
5G technology will instigate new architectures such as virtual RAN and cloud RAN which will provide more centralized networking to make the best use of a local server.
5G will spearhead the use of cognitive radio mechanism that will allow the architecture to automatically decide the channel need to be offered, distinguish between the mobile gadgets and the fixed objects, and it can identify the devices that should be connected with.
Another important part of the 5G cellular system would be, ‘smart antennas’ which can alter the beam direction to provide more direct access as well as enhance overall cell capacity and limit interference.
Additionally, with a lot of access scheme, it can be linked to other ad-hoc wireless system for much rapid data flows.
