What is 4G? Let's know about 4G

I hope all of you know that recently 4G has been launched in Bangladesh. That's a whole new thing for us. So many of us are unaware of this new thing since it's new. So today we will learn about this new topic 4G through this post. So let's look at the details of 4G.

What is 4G LTE?
4G is the short form of the Fourth Generation or the fourth generation. It is used to describe fourth-generation wireless telecommunications technology. This is the successor of the third generation (3G) telecommunications technology. Mobile Broadband Mobile Ultra provides broadband internet services in mobile technology laptops, smartphones or other mobile devices. Among the benefits available at Forsi Network are improved mobile web services, IP telephony, gaming services, HDTV, high-definition mobile TV, video conference, three-dimensional television and cloud computing.

What is LTE?
In a very simple way, LTE (LTE) - Long Term Evolution is a technology of four or four generation of mobile phone networks. English is with LTE - Long Term Evaluation, its full name is the 3GPP Long Term Evolution. Like other technologies, mobile technology is essentially driving any standard standard. International organizations make that ideal, and everybody produces the product accordingly. Otherwise, one will not work properly with one other. Creating LTE standard value is a group called the THREEIPPP or Third Generation Partnership Project, which is working for the Universal Mobile Telecommunications System (UMTS UMTS). From here onwards its name is - THERGPIP UMTS LTE. A lot of terms came, did not it? Again there is a 3G word with THRIPPP. We were talking about 4G, then how did 3G come again! This UMSSE made 3G standard for GSM networks; And now they are working for LTE. If not very technical people, they might be a little messy. But for the general public, it would be understandable that a team called LPIPP is making the theme of the LTE and we will call him LTO short. But the problem with this LTE was that, its standard is still not finalized. It can be called a living standard too. This means that it will continue to change, enhance and revise the next few more years. As it is not standard yet.

There are two types or 4G:
The first mobile WiMAX in South Korea in 2006 and Oslo in Norway in 2009 and the first long term Evolution or LTE service in Stockholm in Sweden. However, there is a debate whether the current versions of 4G can be claimed as actual 4G, the main reason behind this is some of the rules of IMT Advanced. In the United States, Sprint Nextel established a mobile WiMAX network in 2008 and Metropolis launched the first LTE service in 2010. Wireless USB modem was available from the beginning, but WiMAX smartphones have been available since 2010 and LTE smartphone since 2011. But the European market is currently locked for WiMax smartphone sales. Although 4G is not available on mobile phones in Bangladesh, some internet service providers claim that they provide WiMax internet services, although they are suspected.

Ideas about 4G technology:
In March 2008, the IUT-R International Telecommunication Union launched an outline of the necessary contents of the wireless communications sector 4G. They form a speed of 1 Gigabit per second for 100 Mbps and low-speed communication per second for high-speed communication. After the first release of mobile WiMAX and LTE, the services that offer less speed than one Gigabit per second, according to IUT-R's policy, they can not be called 4G services, although service providers market them as 4G services. Mobile supports WiMax release 2 and LTE-Advanced IMT-Advanced content and it is also possible to provide one gigabit-speed service per second. Although the previous generation supports circuit switching, circuit-switched telephony, 4G does not support it. However, it supports all services based on Internet protocols such as IP telephony. It is expected that the next generation of network technologies will be much cheaper and better than previous generation technologies. In many countries, GSM, UMTS and LTE networks are still running simultaneously.

4G background:
Naming different generations of telecommunication technology mainly refers to some technical changes in telecommunications services, such as new types of transfer technology, higher peak data rates, new frequency bands, more storage capacity for contemporary data transfers etc. It can be seen that the telecommunication generation changes after almost ten years. This process began in 1981, from analog (1G) to 1992, with the change in digital (2G) transfer technology and this process continues, through which 3G comes in 3G multi-media support, spread spectrum transfer and at least 200 kilobit / s pick data rate . Then came in 2011-2012, the original mobile, which supports the All-Internet protocol based packet switched network, which gives the user ultra broadband Internet access.

Although ITU imposes certain conditions for technologies that are used in the future, they do not work for their improvement. Rather, some other organizations such as IEEE, The Omeks Forum and THRIPP do all these work. In the mid-1990s, ITU-R released the IMT-2000 conditions, which is used as the condition of 3G technology. Then in 2008, they formulated IMT-Advanced conditions for 4G. The fastest 3G based technology of UMTS family is HSPA +, which has been commercially used since 2009. In this, using an antenna without an MIMA, the downlink is possible to get 28 Mbit / s and uplink 22 Mbit / s speed. Using the DC-HSPA + or 2x2 MIMO in 2011, this trend was upgraded to 42 Mbit / s.

IMT Advanced Requirement:
In the case of 4G, IMT-Advanced Cellular System must meet the following requirements. 4G technology is basically a kind of IP-based network that is 100 Mbps per second for High Mobility Communication and 1 GB of speed per second in connection with Low Mobility. 5 to 20 MHz bandwidth, in some cases 40 MHz bandwidth capacity. In case of Indoor facility, the system will be spectral efficiency, in the case of downlink, 3-bit / s. / Hartz / cell and up to 0.25-bit / s / hartz / cell for uplink.

System Standard:
In October 2010, two standards of ITU-R-4G technology were approved. One is LTE Advanced and the other is Wireless Advanced. 4G technology is basically a kind of IP-based network that is 100 Mbps per second for High Mobility Communication and 1 GB of speed per second in connection with Low Mobility. 5 to 20 MHz bandwidth, in some cases 40 MHz bandwidth capacity. In case of Indoor facility, the system will be spectral efficiency, in the case of downlink, 3-bit / s. / Hartz / cell and up to 0.25-bit / s / hartz / cell for uplink.

IPv6 support:
IP version 6 or IPv6 has emerged after the IP version 4 due to the lack of growing IP. 4G network features IPv6 support. Since 4G technology is an IP based networking system, it is not meant to create a network based on old IPv4. One of the features of the 4G network is the IPv6 support.

Advanced Antenna System:
Advanced antenna system has been used in 4G networking system. Generally, signals are used by an antenna in general networking systems. But in case of 4G networks, multiple antennas are used in the handset. This technology is called Mimo. As a result, bandwidth is very good and high quality voice transmissions and receipts are possible.

Multiplexing and Access Scheme:
Network system modulation system has been added to the 4G technology access scheme. These include the 3GPP Long Term Evaluation System. This is the standard standard of GPRS / EDGE network. All these technologies have been entered into the 4G technology network.

What are the benefits of 4G?
The main advantage of 4G It is possible to exchange information at the highest speed of this network. It is said that the speed will be at least 100 megabytes. It is possible to get high definition televisions and video conferencing facilities through this technology. Apart from this, customers can always be covered under the mobile online broadband under this technology. The security of mobile conversations and information sharing through 4G is very strong and powerful. Apart from this, 4G offers a variety of services including voice message, multimedia message, fax, audio-video recording of mobile subscribers. In addition to its downlink, link spectral effect will be 15 bits per second and uplink to 6 decimal 75 bits. It is assumed that there will be many changes in our lifestyle. But the problem of the country's people is still questionable because the whole country has not reached 3G yet. Where did 3G did not reach there? But at the same time, how much money will bring for the people of the country.

So it's like today I finished the post here. Hope this new thing is about 4G that we all know about this post. Since some of the places in Bangladesh have started 4G. All of them will start slowly. To run this 4G, you will only need 4G support for a mobile, then you can use this 4G.
