5G Technology

5G, A quick glance on 5G

5G is known as an improved version of 4G LTE. To be blunt, this technology is second to none in advance operations on multiple frequency bands on the spectrum of 600MHz. This technology promises faster and reliable internet connectivity to the next generation.

Benefits of 5G

  • 5G is all geared up to improve mobile users in terms of the internet. It will bring new services such as AR and VR.
  • 5G is all set to make new innovations in gaming. It is ready to improvise complex gaming effect and vendors can make games more interesting locally and remotely.
  • 5G virtual reality is in a fit state to fascinate sports fans by creating real-time effects in sports matches while watching on TV.
  • It will also improve efficiency by 30 times and users will experience better services.
  • 5G is a cost-effective solution and its efficiency is 30 times more than previous networks. It promises to provide better services to its users.
  • 5G data transmission rate is quite high- 20Gbps over wireless broadband connections.
  • 5G proffer increased data transmission as there is increased bandwidth already available and antenna technology is also getting advanced.
  • Network slicing is a distinctive quality of 5G which helps in network management. Network slicing is a process in which network operator slice single available physical network into virtual slots. Network slicing is all intended to support specific business operations.

Working of 5g

We can see wireless network as a composition of cell structures which is further divided into sectors and transmit data via radio waves.  5G is an evolution of 4G- thus we can say 4G is the base of 5G.  The 4G structure requires cell towers with high capacity and high-potential to radiate signal over distance, while 5G structure is designed to have small cell stations on multiple places such as poles, rooftops of building, etc. The reason behind the usage of multiple cell stations is that 5G is dependent on millimeter wave spectrum of 30GHz to 300GHz which traverse over only short distances and attenuate due to physical weather conditions.

Services of 5G wireless

  • 5G is offering fixed wireless broadband which provides internet to homes and businesses without any wired connections. Network operators work on the deployment of NRs in small cell towers to project a beam of wireless signal towards the receiver which is fixed on the rooftop of a building. This method of wireless connectivity abolishes roll out of fiber-optic lines towards every home and building and thus making it convenient and cost-effective for network operators to provide broadband services. The duty of network operators is to install fiber optics to cell stations which will radiate wireless signals- these broadband wireless signals will be received by wireless modems installed on customer’s locations.
  • 5G cellular services are featured to allow a user to access the operator’s 5G cellular networks. This service is expected to be available when 5G-devices will be commercially available in the market. As long as completion of mobile core standards is promised by 3GPP- Cellular service delivery of 5G is purely based upon it.

Why 5G instead of 4G?

Every upcoming generation of cellular network technology is more enhanced and varied from the previous one on the basis of speed of data transmission and up-gradation of hardware using enhanced encoding methods.  4G is featured to support data transmission with a speed of 2Gbps. Since 4G is said to be 300 times efficient than 3G, 5G is 100 times faster than its previous networks.

5G is using the OFDM encoding scheme just like 4G but the main difference lies in the latency level which is much lower in 5G.  4G channels are 20MHz with a frequency of 160 MHz whereas 5G channels are between 100 to 800 MHz requiring large segments of airwave as compared to 4G.

Since the race of getting everything perfect is never over- Samsung is doing research on 6G. Up-to this time there is no assumption on speed and accuracy of 6G but surely it will be more enhanced and powerful than 5G and 4G. A little perspective about 6G says that it will be using millimeter waves on the radio spectrum.

The telecom industry is in a continuous struggle of enhancing user experience with cellular networks- it will somehow implement 5G using the same infrastructure as that of 4G but it is in dire need of considerable investments and up-gradation of hardware resources. There is no doubt that there is an increasing need for bandwidth within the spectrum. Using available bandwidth in the electromagnetic spectrum, operators will be able to improve regulations of antennas and radio interfaces.
