4G wireless technology and its features

4G wireless technology and its features: Today we will discuss that what is 4G wireless technology and what features it has.However, today's the everywhere in this world discussion of 5G network technology is very much, but till now we are not fully taking advantage of 4G wireless technology. I feel that 60% of the whole world is still deprived of 4G wireless technology.Some countries have started giving 5G services and some countries are also thinking about the future like 6G. We will talk further on every mobile generation technology but it is also important to know about 4G wireless technology and its features.

Almost all of us are using 4G technology today in our mobile,earlier high speed internet was used only in home and office but this service was not available for mobile.Due to 4G Wireless Technology this problem has ended and now we are taking advantage of high speed internet access everywhere.At home or outside the home, we now get the high Speed ​​Internet service all the way, it's got only due to 4G wireless technology.Earlier this feature was not possible with 1G, 2G or 3G technology.Now I will write about 4G wireless technology in detail.

What is 4G wireless technology

4G wireless technology is a type of mobile communication that is based on IP-based voice,data,gaming service,high quality streamed multimedia support in portable device. 4G technology was started in the year 2000. 4G wireless technology provide  the speed of the Internet from 100 Mbps to 1Gbps,Watching TV without buffering, video calling, downloading movies, software, games on smartphone is a easy task.Earlier due to the overuse of consumers, the speed of internet was reduced, now the problem has been eliminated due to 4G wireless technology.

4G Technology is very different in terms of 3G technology.In the last 10 years, mobile technology has improved greatly due to which we are now taking advantage of 4G wireless technology.The main purpose of 4G wireless technology is to improve the high speed,high quality and high capacity network and provide to the users.In addition 4G technology provides security and reduces the possibility of data breach.

The main services in 4G technology is current application,mobile web access,IP telephony,gaming services,high-definition mobile TV,video conferencing,3D television and cloud computing. MIMO (Multiple Input Multiple Output) and OFDM (Orthogonal Frequency Division Multiplexing) used to obtained 4G wireless technology in better way.

Main standards of 4G wireless technology

The main standards of 4G wireless technology is WiMAX and LTE. Now we talk about these two briefly.

What is WiMAX?: Abbreviation of WiMAX is Worldwide Interoperability for Microwave Access.This is a wireless Industry Coalition that's completely standard to IEEE 802.16. WiMAX Mobile supported for BWA (Broadband Wireless Access Network),Fixed Wireless Application.Its main purpose is to make the device more compatible and interoperable for its use.Wemax is competing with his competitor LTE.

What is LTE?: Abbreviation of LTE is Long Term Evolution.It is also a standard of 4G wireless technology that increased network capacity and speed to the mobile devices for their users. LTE technology introduced so many technology as compared to previous cellular system. LTE technology helps to be easily operated. These technologies are OFDM (Orthogonal Frequency Multiplex), MIMO (Multiple Input Multiple Output) and SAE (System Architecture Evolution).

What is VoLTE?: The meaning of VoLTE is that Voice-Over-LTE. This is a new technology in which the user phone call are placed over the LTE network, in lieu of typical phone calls according to data packets.Therefore it is called packet voice and packet is easily shared in the network. VoLTE support too many callers together and can relocate bandwidth when needed.The packet voices provides the facility to the users that the when calling to a person that is busy or not.

4G standard set the few requirements, using Internet Protocol (IP) for mobile networks, it is necessary to have 100 Mbps of minimum data rate for data traffic. For better description 4G Technology is also known as the MAGIC. Here MAGIC is interpreted in such a way-
M- Mobile Multimedia
A- Anytime Anywhere
G- Global Mobility Support
I- Integrated Wireless Solution
C- Customized Personal Service

The meaning of LTE is Long Term Evolution and we can not even call it a technology because it used to get the 4G speed. It is complete redesign and simplification of 3G network, the result of which is the signal reduction in transfer latency and this increases both the efficiency and speed of the network.

History of 4G Wireless Technology First Generation

4G Wireless Technology First Generation of Networking first of all, it was released in 2009 in the Sweden.After that it was more developed and developed worldwide. Now we try to know about the 4G wireless technology features.

4G wireless technology work on the band 1800 MHz, 2600 MHz and 800 MHz.
The most important technology used in 4G wireless technology is the LTE and WiMAX.
4G wireless technology also uses some different technology like OFDM,MIMO,S-FDMA to provide the services.
The person who is traveling in a vehicle with a speed of 350 mph supports the high data rate of those people.According to the ITU-R, it can easily support up to 100 mbps in a moving objects like car, bus or train.Stationary users and low mobility users like pedestrians get the 1000 Mbps/1 G data speed.
4G wireless technology simultaneously support 200 voice call in a single carrier.

What was the limitations of 4G

Now I would like to mention about the limitations of 4G wireless technology.

Implementing of Next Generation Network the battery used is very difficult to implement,.for which a lot of expensive and complicated hardware is required.
4G wireless technology requires expensive infrastructure to operate, whose eNodeB's (Access Point) and mainly EPC's (Gateway and Router) embodied. 
4C wireless technology data rate is optimal, this does not mean that it is good for all voice service,some services in your phone are only for Wi-Fi or 3G / GSM cellular technologies.
It is more expensive for the implementation.
There are also many types of complex hardware used.
It uses a lot of power.

We are still seeing that something new in mobile technology is taking birth new technology in 5-10 years.In the name of new technology in the Telecom Sector, the previous version is upgraded.Some countries have also upgraded 4G wireless technology to 5G and commercially launched and its work is going on worldwide.Now I will write about 5G wireless technology in the other article.
