Technology has advanced in last two decades which is evident from rapid developments in field of wireless technologies which are marking their existence into all aspects of human life. 4G has made it place at the top. The main goal of 4G is to embed broadband in all types of portable consumer devices. The vision of 4G is backbone for an advanced infrastructural framework consisting of architecture, advancement in core technologies like processor and digital signal processing and open interfaces for building, deploying and providing applications to achieve ubiquitous, seamless capacity agnostic services.
3G deployments began as early as 2003 in some countries and now most developed nations have implemented 3G networks with coverage in billions of subscribers. Scope of 4G expands access to all types of networks in category of non-mobile methods, wireless and wireline. The future average revenue per user for 4G will mainly come from data services such as mobile, video, music games, internet access, navigation and messaging. 4G will lead to converging of power and radio receiver technology with processor technology leading to innovating softwares to combine media, user profiles and location. Further, other non-market factors for support of 4G framework development are Industry standards, cultural norms, government regulations, state of technological developments and country’s intellectual property infrastructure.
Data download speeds from 2G to 4G
The emergence of 3G wireless technology has enabled faster data transmission speeds, greater network capacity and more advanced network services. ‘4G’ is the term used to refer to the International Mobile Telecommunications Advanced Technology (IMT-Advanced) family of mobile wireless services. 4G basically extends 3G technology with more bandwidth and services offered in 3G. The specification under consideration is the high speed for the data transfer with online security. Two technologies are supposed to be base features of 4G ie WiMax and LTE. WiMAX stands for worldwide interoperability of microwave access previously worked as fixed wireless facility under the 802.16e band. Now modified standard 802.16m has been developed with the properties of the speed, wide spectrum and increased bandwidth.
International Telecommunication Union using Radio defined 4G Mobile Technology as IMT-Advanced (International Mobile Telecommunication) . It is considered to embed IP feature in the set for high data rates. Instead of CDMA and IS-95 a new technology OFDMA is introduced in 4G which divides channels for greater efficiency. Further, IPv6 is approved by Verizon as a 4G standard. In India , Bharti Airtel has launched India’s first 4G service. The need of the hour is to pay more attention towards identifying the path and the strategies that will shape the 4G markets more capitals and investments for our country. We should get the infrastructure and machinery required for 4G implementation for one of the earliest bidders for the 4G spectrum for overall development and growth of nation.
