What is 5G

5G is started launching in early 2019. No individual person or one company owns 5G, but there are a number of companies within the mobile ecosystem are contributing to bringing 5G to life. It is the 5th generation mobile network. It is a worldwide wireless standard after 1G, 2G, 3G, and 4G networks. 5G facilitate a new kind of network that is designed to connect virtually everyone and everything in support including machines, objects, and devices. 5G wireless deliver higher multi-Gbps peak data speeds, ultra low latency, more reliability, massive network capacity, increased availability, and a more uniform user experience to more users.

Technologies make up in 5G

5G is rooted in Orthogonal frequency-division multiplexing (OFDM), a method of modulating a digital signal across many different channels to decrease interference. It uses 5G NR air interface alongside OFDM principles. It also uses wider bandwidth technologies such as sub-6 GHz and mmWave. In 4G LTE, 5G OFDM operates rooted in the same mobile networking principles. But, in 5G NR air interface can further enhance OFDM to deliver a much higher degree of flexibility and scalability. 5G fetch wider bandwidths by going up the usage of spectrum resources, from sub-3 GHz used in 4G to 100 GHz and beyond. 5G can operate in both lower bands (e.g., sub-6 GHz) as well as mmWave.  Frequency rang in 5G is 3.3–4.2 GHz.

5G in Businesses use

As it is high data speeds and superior network reliability, it will have a great impact on businesses. The benefits of 5G will improve the efficiency of businesses while also giving users faster access to more information. Based on the industry, some businesses can make full use of 5G capabilities, especially those needing the high speed, low latency, and network capacity that 5G is designed to give. Eg. If factories could use 5G to run industrial Ethernet, will help them increase operational productivity and precision.

Differences between the previous generations of mobile networks

1G	2G	3G	4G	5G
1980s. IT is delivered analog voice	Early 1990s.   It is introduced digital voice (Example CDMA- Code Division Multiple Access)	Early 2000s. It is brought mobile data (e.g. CDMA2000)	2010s. 4G /LTE ushered in the era of mobile broadband	5G is a unified, more capable air interface. 5G been designed with an extended capacity to enable next-generation user experiences, empower new deployment models and deliver new services with high speeds, superior reliability and negligible latency. 5G will develop the mobile ecosystem into new realms leads to impact every industry

 

5G application in Smart Library

Integration of 5G in smart libraries is an inevitable development trend of smart libraries. Smart Library technology is capable to be kept open to library users without being Library staffed. The technologies make possible to remote control of library buildings, including automatic doors, lighting, maintaining temperature with in library, self-service kiosks and public computers.
