MAGIC of 4G Technology

 

So far there has been no specific definition to this successor of 2G and 3G. However it has been used often to denote a fast internet access available to mobile phone users. More over the distinguishing feature of high multimedia streaming and end to end IP configuration is judged to be its MAGIC enchantment.3G utilized WiMax and WiFi as separate wireless technologies, whereas 4G is expected to coalesce these two technologies. Hence one can evaluate how efficient it would become when combining two extremely reliable technologies. 4G can greatly anticipate in evolving and advancing the pervasive computing. The aim of pervasive computing is to attach itself to every living space possible, so that human beings remain intact with the wireless technology intentionally and unintentionally. Therefore 4G is  be able to connect various high speed networks together, which would  enable each one of us to carry digital devices even in dispersed locations.   The network operators worldwide would be able to deploy wireless mesh networks and make use of cognitive radio technology for widespread coverage and access.

4G Technologies

 

4G is a multi purpose and versatile technology hence it can utilize almost all of the packet switched technologies. It can use both orthogonal frequency division multiplexing (OFDM) and orthogonal frequency division multiple access (OFDMA). OFDM mechanism splits a digital signal into different narrowband and frequencies. The reason why 4G makes use of this technology lies in its ability to minimize the intervention among symbols and channels associated to data streaming.4G is also capable of using multiple input / multiple output technology (MIMO).this antenna technology is used to optimize the data speed and reduce the errors in the networks. Universal Mobile Telecommunication Service (UMTS) which is basically a broadband 3G technology is also a part of 4G. This broadband technology transfers data in the form of frames or packets. Hence it is capable of carrying voice, video, text and other types of multimedia datagram with the speed of 2Mb. UMTS is part of 4G because it can enables 4G to make use of international mobile phone roaming via using GSM (Global system for Mobile Communications).another wireless telecommunication technology known as time division synchronous code division multiple access (TD-SCDMA) provides support to 4G to transfer both circuit switched data like video and voice and packet switched data.

 

4G’s New Horizon of Opportunities

 

The telecommunication companies like NTT Docomo from Japan and Sprint Nextel were also deploying 4G wireless technologies from the early 2006 along with 3G mobile technologies. The flexibility of 4G technologies to be used in combination with GSM and CDMA has provided it an edge over other technologies. The reason is that the high broadband capability of 4G not only increases data streaming for stationary users but also for mobile users.4G can be efficiently combined with cellular technologies to make consistent use of smart phones. The digital cameras attached in smart phones can be used to establish video blogs in scattered geographical regions. This gives the manufactures the opportunity to produce more affordable user friendly 4G compatible devices. Famous iPod is one such device that supports the working of video blogs. Hence 4G is capable of providing new horizon of opportunity for both existing and startup telephone companies.

 

4G (Fourth Generation) Network

4G is the next generation is the next step into wireless and cellular technologies. This technology can be also associated with high speed and remote connectivity any where in the world. This technology is still under the phase of development, but it hopes to overcome the limitations of its bequests. The overall mission of researchers and network developers is to make secure and high speed data connection. With its flexible channel bandwidth it can replace 3G and 2G technologies entirely. This technology would be blessing for digital portable gadgets freaks because this technology would provide high speed connectivity with less signal attenuation.

 

Specifics of 4G

4G technologies are geared towards flawless network coverage. This technology is aimed to provide high quality of service to end users without dropping signals. The major problem with the wireless technologies is their signal attenuation. International telecommunication union, which is monitoring the international standards for wireless communication is demanding considerable improvement in multi media services over the cellular network. They require improvement in multimedia message services and video streaming in order to support 4G. This network technology is expected to provide 100megabits per second for mobile users, while 1GBps for fixed users. This network is also forecasted to provide interrelated roaming throughout the world. It is also predictable that this technology would be attuned to all types of wireless devices like wireless

adapters, express cards and many more. The infrastructure of 4G will follow all the standards of previous generations.

IPv6 Requirement

4G network is based on IPv6 support rather than IPv4. it is IPv6 which is supports network devices. Increased number of IP addresses also removes the need for NAT (network Address translation). NAT is a term referred to sharing minimum IP addresses with larger number of devices. Besides this improvement Nat would also has to communicate with the other devices on the previous IPv4 devices. 4G has also brought improvements in network infrastructure. For example 3G used both circuit switched and packet switched network nodes, while 4g is merely based on packet switching, hence lowering the latency of data. The basic 4G standards include LTE advanced and 802.16m.

 

 

Objectives of 4G:

This wonder technology is expected to cover the data rate deficiency in previous generations. It is also aimed to achieve quality of services. This technology would

provide many multimedia services. These multimedia services would not only include voice chat and video calls but also includes MMS, HDTV, video chat, and voice over the internet. This network would allow interactive roaming with existing LAN and digital broadcasting systems. This network's goal is to provide 100MBps data rate for moving customers and 1GB for stationary users.. So that the users can enjoy uninterrupted connectivity with high speed anywhere they go. Very smooth handover over heterogeneous networks. Flawless connectivity and international roaming across innumerable networks of the world is its next target. It should also provide Very high quality multimedia support in order to get approval from ITU. The interoperability with existing network infrastructure is another prominent feature of this technology. It is an all IP switched network and several working groups propose that it should offer an open internet protocol. The early 4G technology comprise of flash OFDM, 802.16e, wireless or mobile WiMax and HC SDMA. The demand of the wireless network users combined with the efforts of the 4G working groups would give technology and edge over its previous counterparts. This technology would revolutionize the world of cellular networks with amazing wireless broadband speed. This technology would also provide job opportunities for many. The further development for supporting 4G network is dependent upon the approval from ITU.
