An overview of Mobile Technology: 1G, 2G, 3G, 4G and 5G
People like to socialize and make connections and the world now looks smaller than ever all due to miraculous gadgets people own. The mobile phone is one of them and appears to be a commonly used gadget these days. People usually have prepaid or postpay connections from their service providers other than handsets they own to communicate with each other. The development of mobile technologies is fast-paced and the future it offers is unlimited. Let’s review the past, present and future mobile technologies to get the know-how of things as they are Usually the mobile technologies are characterized by names such as first-generation, second generation, third generation and fourth generation mobile technologies.
First Generation Mobile Technologies: Nineteen eighty-three was the year when cellular phones and cellular networks arise first company to introduce the cell phones are formally Motorola who was then famous for radio installation in cars. The cell phones got popular in the eighties and were larger in size as compared to mobiles of the modern world. Basically, they were developed to be installed in automobiles and were commonly known as car phones.
Second Generation Mobile Technologies: Nineteen nineties was the era when second-generation mobiles got fame. These are commonly known as 2g-mobiles or cell phones. The network signals were better with advanced digital circuit transmission. The mobile sets were reduced in size and look better than the previous first generation mobiles. It was also the time when short text messages were introduced and now people prefer using it over voice calls.
Third Generation Mobile Technologies: Third generation mobiles are also known as 3 G mobile technology. 3 G is the name given to st of standards and technical specifications for mobiles developed in the third era of mobile technology. The advanced level of 2G mobiles is known to be 3G mobile technology. With the advancement of technology and increased need of accessibility to data and socialisation and world wide web the mobile technology developers initiated and successfully launched the mobiles that not only supports voice calls but also images to display this is the time when the concept of video calling had emerged to surface and get popularity among its users.
This was also the time when access to the Internet through your mobile sets was made possible for the consumers. The Internet access your 3G mobile offers is of high speed that is a broad band. Although the 3G mobiles got a very famous but common complaint from the users is that the vendors have not introduced them at an affordable price. Although the features are worth a price but they still are expensive.
Third-generation mobile networks, or 3 G, launched in the U.S. in 2003. At a minimum stable Internet speed of 144Kbps, 3 G was intended to offer “mobile broadband.” There are now so many variations of 3 G, however, that a “3 G” service will give you Internet speeds anywhere from 400Kbps to more than ten times that.
Fourth Generation Mobile Technologies :
New generations typically carry new basic technology, more network power for more data per user, and potential for improved voice quality. Apple was the first which introduced the 4G iPhones which had new great features and still needed to be reviewed with details. The basic features that differentiate 4G mobile with 3G mobile is the live streaming of radio and television. Nowadays 3 G has become obsolete and even 4G technology is replaced with most advanced 5G technology.
4 G phones are meant to be quicker, but that’s not always the case. There are so many technologies called “4 G” and so many ways to incorporate them that the word is almost meaningless. The International Telecommunications Union, a standards body, sought to set down conditions to call the 4 G network, but the carriers ignored them and finally the ITU backed down. 4 G technologies include HSPA+ 21/42, the now obsolete WiMAX, and LTE (although some find LTE to be the only true 4 G of that group, and some claim none of them is good enough to qualify).
This is, however, a major difference between 4 G LTE and other systems branded “4 G” and that is most apparent in upload rates. When you upload a lot of data-for examples, post images or videos you can find that LTE upload speeds are much higher than HSPA upload speeds.
There are also many different ways to implement LTE, so you can’t assume that all LTE speeds are the same. Carriers with more available LTE radio spectrum can normally run faster networks than carriers with less spectrum, for example.
Fifth Generation Mobile Technologies
These are past and present of the mobile technologies and the future is the fifth generation or 5G mobiles. With this much rapid evolution of technology, it never seems to be ending, even sky is the limit with creativity and innovation when it comes to mobile technologies.
5 G Technology and its Need
5 G seeks to deliver a range of high-speed networks to end-users. The applications designed to use these services are highly user-friendly, reducing the interaction between the application and the user. For example, the introduction of speech recognition technology into user interfaces will make it simpler for any layman to use the applications.
The key benefit is Interoperability, Various 4 G requirements limit the accessibility and connectivity of users across multiple networks. 5 G aims to provide a unified global standard that will facilitate global mobility and portability of services. In other words, end-users can subscribe to different services from different service providers using the same mobile device.
As technical requirements over currently
existing technologies (4G) lists the
1000 times the volume of mobile data per area,
-10 to 100 times the average user data limit,
-10 to 100 times the number of wired computers,
-10 times longer battery life for low-power applications,
-5 times reduced end-to-end latency.
̈ Key challenges for development:
-Cognitive Radio (CR)-New methods of usage spectrum.
Software Defined Radio (SDR) – Reconfiguration enabler.
-Reconfigurable-Interoperability between many forms of wireless networks.
-Adaptive coupler-Reconfigurable integration.
-The Energy Efficiency Network.
