REVOLUTION TO 5G

 


What is "G" 

That 1 G, 2G, 3G,4G and 5G are different generations of mobile networks, 1980 to 2020. "G" convey the meaning of the generation. As shown in the above image, every decade, a new generation was introduced with a specific set of standards with each generation. Especially the speed of those networks is increased.

Journey From 1G to 5G

1G

1G was the first generation and it was the wireless telephone technology introduced in 1980 and completed in early 1990. Its speed was up to 2.4kbps. It allows the voice call in only one country. 1G network was using only analogue signals. what do you believe that compared to today's world and in 1G technology?. Amps were first launched in the USA in 1G mobile. Although 1G was the biggest revolution of its time. But in 1G there were a lot of drawbacks such as poor voice quality, the poor battery life, no security anybody can hake your limited capacity and poor handoff reliability. Because of that world move to the 2G technology.

  2G

2G refers to the second generation which is actually based on gsm which was launched in 1991. 2G was the biggest advancement compared to the 1G because in 1G  we had 2.4kbps and in the 2G, we got its data speed was up to 64kbps. It was a marvellous turning point for mobile developers. It enables services such as text messages, picture messages, multimedia messages and it also provided good quality incapacity. The major drawbacks of 2G were the 2G required strong digital signals which were not that much at that time. because they require a lot of towers to be plotted everywhere to help mobile phone work. If there is no network coverage in any specific area your digital signals would go weak. Because of this, complex data such as videoes are unable to handle.                                                                                    Then with the advancement of 2G, 2.5G was introduced. That was included in your only phone calls. The biggest advancement in 2.5G was the speed. it increased the speed from 64Kbps to 144Kbps. At that time the camera phone also was introduced. with 2.5G speed, we were able to download 3minute video about six to nine minutes.

3G

In 2000, we moved to the 3G technology. with 3G, data transmission speed increased from 144Kbps to 2Mbps amazingly. At that time smartphones were introduced and their features were increased according to their brands. And they accommodate weight-based application and audio and files. In that way, the app store came to existence. And 3G went for a long time providing faster communication. Send and receive large email messages, high speed waving more security video and 3d games. The important thing was people who were downloading three minutes video around 9 minutes, it took them only 11 seconds up to 1 minute. The major drawback in 3G is, it is expensive.

4G

Now the 4G era, 4G is just the advancement of 3G. It has got nothing much than increasing its data rate from 2 Mbps to the 20 Mbps. and it also uses the packet switching system and everything is about same only the internet rate speed has been faster in 4G.

 5G

5G is at the new tech. This technology has revolutionized everything, anything you might have never seen before. It is much faster than the normal internet speed. It's 10 to 100 prime faster than your 4G. The important thing is you can find the coverage anywhere. If you use 5G for your mobile phone, the network energy which your phone uses will be reduced by 90% that means 90% reduction in the network energy and it will benefit your battery life. With 4G, we were able to connect up to 100 numbers of connected devices per unit area. In 5G, that number has been increased up to 1000 brand with per unit area.

      Thank you for the question. Lower latency with 5G is achieve through significant advances in mobile device technology and mobile network architecture. both core Network and Radio access network are required to deliver low latency.

      Yes osura, we can expect 6G commercially like in 2030. The speed expectation is nearly 95GB/s.

    Though it doesn't exist yet, as the next revolution of telecommunication, 6G will grab the attention from 5G sooner. As per my knowledge, it's still in theoretical speak. Some companies like Nokia, Samsung, LG and Apple have shown an interest on this.

What is Social Engineering? Social engineering is that the term used for a broad vary of malicious activities accomplished through human interactions. It uses psychological manipulation to trick users into creating security mistakes or giving freely sensitive data. Social Engineering techniques Social engineering may happen in different forms anywhere where human interaction is involved. There are five most common forms of digital social engineering techniques. Baiting Scareware Pretexting Phishing Spear Phishing Baiting The way attackers do suits with English mean of the baiting. Actually, in Baiting, attackers find something the victim greed or curiosity. After making a friendship with the victim, trap the victim and steal their personal information or inflicts their systems with malware. The most reviled form of baiting uses physical media such as an infected flash drive.  But through online also attackers may attack using baiting. In this way, attackers might use some advertise...

NEED OF SIEM TOOL FOR ORGINIZATION

Image
  What is SIEM? SIEM stands for Security, Information and Event Management and it's pronounced SIM, "E" is silent when pronouncing. The main purpose of SIEM is, it is a system that collects log files, security alerts and events into one place. So security teams can more easily analyze data. An in another way you can think of a SIEM as a log management system specialized for security. How does SIEM work? SIEM collects all the information from other security systems like endpoint security, endpoint security, firewalls, intrusion detection systems. The logs and alerts from these systems needed to be stored centrally. So that analysts didn't have to go to each individual security product to conduct the investigations. Above image shows the tasks done from SIEM tool.  SIEM offer powerful log search features, the ability to trigger alerts using rules and reports that organizations can provide to auditors to demonstrate compliance with various regulations. The new SIEM is up...
