4G LTE Network Growth in India and Security Issue in Network
The advancement and migration of the broadband wireless communication technology into the next generation technology known as Fourth Generation (4G) network has indeed become the next emergent wireless revolution, as an important milestone beyond third generation. 4G networks are introduced with the main intention of customization of a flexible and ubiquitous service provision in the middle of 2012 based on digital broadband packet and all IP very high throughput speed of 100300 Mbps in peak. The widespread growth of the 4G technology in India will be driven by set of new services which will be made useful for the customers such as accessing the internet and video anywhere, any time and in any places with global roaming and full fledged support for all other multimedia applications. In India even though 4G technology is introduced early in the year 2014, it's still not widespread due to some of the challenges faced by the mobile or wireless communication service providers. 4G has the advantage of mobility, high data rates, high capacity and preservation of full backward compatibility. The high speed capability and wider coverage has been a good achievement for 4G networks. Nevertheless, security and improved higher speed with a better quality of service (QOS) has been an issue in its network operations due to the open nature and all IP infrastructure of 4G network. Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (Wimax) are among the numerous new innovation technologies which have evolved as leading contenders for the 4G technology. This article explores the trends in the evolution of 4G wireless technology and its security limitations. Finally, it evaluates and recommends ways of tackling the security issues in 4G network.
