4G which stands as Fourth Generation is the upcoming next generation technology which will wipe its predecessor 3G out of the surface of the world. The 4G technology has promised to offer widespread, complete and invulnerable all-IP (Internet Protocol) based services example of such services are high quality multimedia streaming, enhanced gaming services, super fast broadband Internet access, IP telephony and etc. All these and many more facilities will soon be available to people all around the world by this groundbreaking technology.
4G which is also be referred as “International Mobile Telecommunications Advanced” in short IMT Advanced promises to have a targeted maximum data speed up to around 100 mega bytes per second for outdoor users like instant access to Internet by mobiles or smartphones and for indoor users like the LAN (Local Area Network) users the data speed would be around 1 Giga bytes per second, for both the mobile or fixed stationed Internet users this type of higher speed, which has never before, is truly awesome and mind-blowing. Also up to 40 mega hertz of scalable bandwidth must be provided, according to ITU requirements. The frequency-domain equalization policy has removed the CDMA spectrum radio technology that was being used by the IS-95 and 3G stations.
The reason behind the development of 4G is to provide accommodation for the required Qos and rate that was set as requirements by the advanced growth of current 3G applications such as, mobile TV, wireless broadband service, video chat, MMS that stands for Multimedia Messaging Service and also the famous HDTV contents. The fourth generation technology may also provide wireless LAN roaming and may also intermingle with systems that are used for digital video broadcasting.
Here are the main objectives that 4G will offer when after it is fully developed.
100mbps would be the normal data rate for the users who are not stationary and moving at high speeds and 1gbps would be the maximum data rate when the user is indoor or at a fixed position.
Bandwidth flexibility, between 5 to 20 mega hertz maximum up to 40 mega hertz
Worldwide roaming over multiple networks and flawless connectivity
Spectral efficiency downlink up to 3 bit/s/Hz/cell and for fixed or indoor usage 2.25 bit/s/Hz/cell
All-IP based network means packet switched network
There are many other objectives that the 4G working group has set to attain.
Sprint is providing 3G and 4G data plan in limited cities in the US and offers speed up to 10 mega bytes per second.
What Is The 4G Wireless Technology?- A Basic Information
We have seen and use the 2G (second generation) technology and 3G (third generation) technology. They are some old and current technologies for internet. When the speed and reliability of 2G was not enough, the 3G technology was developed. This 3G technology offered the world with new possibilities of using internet. With faster speed and greater reliable network than 2G, the 3G surely satisfied many users around the world. However, in this day and age, the demand for internet has become much greater. People are now seeking for more speed, good reliability and good network as the current facilities are not enough. This growing demand has become too much pressure on 3G and it is now unable to hold anymore stress. Therefore, a new generation technology, a successor of 3G technology is now being developed. It is a 4G or fourth generation wireless technology.
It is being said that the 4G technology will greatly surpass the 3G in every way. Its introduction will offer a greater capacity, even faster speed and more reliable networks. The 4G wireless technology will also offer a greater coverage which even 3G was unable to do. It doesn’t matter whether you are traveling or you are in a far away location, the 4G will surely enable you to access internet from any device which support internet. This means that, not only you can access faster speed from home, but also you can enjoy the faster speed from your mobile phones. Currently, many mobile operators are in a process of changing their networks according to 4G technology so they can provide 4G service ASAP. Some operators will use WiMAX and some will be operating the LTE technology.
WiMAX And LTE
WiMAX or Worldwide Interoperability for Microwave Access, some sort of a faster Wi-Fi, is a technology which comes under the brand of 4G technology. WiMAX have its own benefits but it will most beneficial for only those mobile operators who are using latest spectrum bands.
LTE or lont-term evolution is also another technology which comes under the brand of 4G technology. It is very similar to WiMAX. Upgrading the current 3G networks to LTE is easier than upgrading to WiMAX and it is capable to giving a full support to the spectrum bands.
There is not much of difference between the WiMAX and LTE. Both of these technologies are a part of 4G. Thus, we can understand that both of these technologies will offer a greater speed.
The speed of 4G technology is it important feature. The researchers have found that it is capable of providing a maximum speed of 1GBps when the user is not in motion and 100MBps when user is in a high speed motion. The connection and network of 4G will be uninterrupted, smooth and reliable. With such a great technology, users can enjoy the speed, like that of broadband connections, even in mobile. The introduction of this technology will revolutionize the world of internet. Two-way communication in audio and video, HD video streamings, high-speed data transfer, higher bandwidth and many other services will be possible.
The benefits of 4G wireless technology are endless and it will offer such a service which is beyond human expectations. Soon this technology will be available to you and then you will be to access internet from any device and from anywhere.

4G Wireless Network Technology
The name 4G is for further advance invention in wireless networks likely mobile phones to the up coming generation. One contributor in several parts of United States of America only offered it in 2009. Un till now no company contracted to represent 4G mobiles technology, currently it is just only a market term.
The alphabet “G” in term 4G means generation, in wireless networks like cellular phones using “G” technology from last 20 to 30 years. The technology o 1G occupied the first commonly existing cellular phones, the launched of 2G technology in begin of year 1990 brought a digital format of text messaging. After introduced of 3G technology which also brought a great option to carry data or improved info-services of how to carry websites in the original form. Now day’s iPhone is the latest and well-recognized exemplar of 3G mobile technology.
Un till now 4G mobiles is not set up as a contract. Therefore the appearance of 4G merely a market term and somewhat necessities. There should be safe and secure connection of 4G because if it’s high rate data transfer speed. An additional objective is to provide good network coverage because some time it causes trouble when it is use between several network-covered areas. An IP address based network programs should use in 4G mobile technologies for using Internet services.
The two foremost system Wimax and Clearwire, are using 4G mobile technologies within the boundaries of United States of America, a organization where major part of proprietor is Sprint Nextel. In 2008 at Baltimore it was the start of testing services further they planned to spread it out in markets in 2009. So they set up a plan to provide coverage up to 80 cities till end of 2010.
Generally Verizon backs the competitor methods, durable Evolution or LTE. It was probably anticipated that they make it prepared for testing in 2010 but due to the LTE sponsor prevail over some inconvenience by providing higher speed and manufacturing contemptible equipments, it will launch for common usage in 2012.
The Fourth Generation mobile technologies will be commonly used in cellular phones and also in computers for using Internet services. In areas having good network coverage can also avail the services of connection of home broadband without installing any cables and wires. The 4G wireless connections can be easily carried to everywhere for using Internet services and can it use when you are hanging out with friends, airports, subways, and coffee café.
